Frictional shaft-hub-connections

Why frictional shaft-hub-connections: Frictional shaft-hub-connections are standard machine elements used to connect shafts and hubs. They are capable of transmitting Torque, axial forces, radial forces and bending moments.

Shrink Discs and Cone Clamping Elements: Among the frictional shaft-hub-connections Shrink Discs and Cone Clamping Elements take an important position. By tightening clamping screws conical surfaces are pulled together generating radial forces; these forces provide the required frictional connection between the parts involved in the transmission of torques or forces. Shrink Discs and Cone Clamping Elements are capable of transmitting much higher torques than conventional positive connections with keyways. The shafts can be designed smaller and shorter. The relationships between shaft diameter and shaft length are illustrated in the example shown in figure 1-1. In this comparison, the same torque is transmitted via a Cone Clamping Element (upper half of the figure) and via a keyway connection (lowers half of the figure). The Cone Clamping Element design offers a much more compact and cost effective solution.

Categories of RYDON Shaft-Hub-Connections

Shrink Discs

Shrink Discs are external clamping connections for the backlash free fastening of hollow shafts or hubs to shafts. By tightening clamping screws conical surfaces are pulled together generating radial forces, Torques or axial forces can be transmitted frictionally from the hollow shaft to the shaft. The shrink Discs itself is not involved in the transmission of torques or axial forces. The radial clamping forces which act through the circumference of the hollow shaft also ensure an optimum centering to the shaft.

Shrink Discs are used, for example, to fasten machine shafts to gearboxes with hollow-shafts.

Cone Clamping Elements

Cone Clamping Elements are internal clamping connections free fastening of hubs

on shafts. By tightening clamping screws conical surfaces pulled together

generating radial forces, these forces create a frictional connection between the

Cone Clamping Element to the hub.

Cone Clamping Elements are used, for example to fasten sprockets, flywheels,

levers, pulleys, brake discs or conveyor-belt drums.

Ensured Torques with the RYDON Calculation Method

The RYDON calculation method takes into account the friction-coefficient fluctuations which naturally occur in all screw connections. The transmissible torques or axial forces listed in this catalogue are based on friction-coefficient fluctuations in accordance with VDI Guideline 2230 and are minimum values. This ensures a reliable selection of the shaft-hub-connection.

In contrast, torques shows in catalogues issued by various other manufactures are based on simplified calculation methods. These catalogue values are often comparatively higher, but are subject to the friction-coefficient fluctuations described below and thus do not represent reliable minimum values for customers and users

In most frictional shaft-hub-connections, the frictional connection is created by torque-controlled tightening of screws. These axially positioned screws are tightened to a specified screw tightening torque. On the basis of the determined preload forces and transmission ratio of the conical angles, the radial forces between the clamping element and the shaft or hub are calculated by taking into account friction losses. With these radial forces and the friction coefficients between the components the transmissible torques or axial forces can be calculated

The determination of the correct actual preload force in a given application is of prime importance. Simple calculation methods are based on an assumed preload force, from which the pressures (and thus the component stress factors) as well as the transmissible torques or axial forces are calculated. The use of such calculation methods is dangerous, as friction-coefficient fluctuations lead to actual preload forces that are higher or lower than assumed. If the actual preload forces are also higher than component stress factors are also higher than calculated, which can cause component damage (e.g.to the hub) in extreme cases. In the opposite case, when the preload forces are lower than assumed, the calculated torques or axial forces may not be transmitted. Consequently, the connection slips.

The RYDON calculation method ensures that such errors in the dimensioning of shaft-hub-connections are avoided. This is achieved by using a method that has been tested and proven over many years, according to which the real friction coefficient µK in the contact area under the head of the screw and µG in the screw threading line between 0.10 and 0.14. This conforms to current engineering standards as described in VDI Guideline 2230. The RYDON method for calculating preload forces is described below using the example of a M10 screw with a hardness rating of 12.9

As the actual friction coefficient in a given case is unknown, the screw tightening torque Ms must correspond to the lowest friction coefficient of µ=0.10(Ms=73Nm) according to the RYDON calculation method. If a higher tightening torque is used, the screw could be overloaded.

If the actual friction coefficient is µ=0.14, then the preload force Fs=52.1kN will not be achieved with a screw tightening torque of Ms= 73Nm. The preload force will be only Fs=38.8kN, where as the component stress factors in the hub are calculated on the basic of a preload of Fs=52.1kN.

Design and Function of Shrink Discs

Two-part Shrink Discs

Design and Function

Two-part shrink discs consist of an outer stopped conical ring, and an inner stepped conical bush, as a number of clamping screws (see Figure 4-1).

The stepped conical ring is pulled onto the stepped conical bush by tightening the clamping screws. A radial clamping force is generated by the conical surfaces, which is independent of the friction coefficient at the screws and conical surfaces, the radial clamping force presses the hollow shaft onto the shaft and creates a frictional connection at the hollow shaft. Thereby, torque and /or axial force can be transmitted between the shaft and the hollow shaft.

During the clamping process, the position of the stepped conical bush relative to the hollow shaft remains unchanged. The connection is released by tightening clamping screw in the threaded bores for the jacking screws.

Design and Function of Shrink Discs

Distance-controlled assembly

The clamping screws are tightened uniformly in a clockwise sequence until the face of the stepped conical ring is flush with the front face of the stepped conical bush (see Figure 4-2).

Once this assembly state is reached, the torque or axial force values shown in the tables can be reliably transmitted between the hollow shaft and the shaft.

Insufficient or missing lubrication of the conical surfaces as might happen during servicing will make the assembly procedure impossible to complete.

Three-part Shrink Discs

Design and Function

Three-part shrink consist of a threaded flange, a pressure flange, a slotted inner ring and number of clamping screws (see Figure 5-1).

The threaded flange and the pressure flange are pulled together over the inner ring by tightening the clamping screws. A radial clamping force is generated by the conical surfaces which are dependent on the friction coefficients at the screws and conical surfaces. The radial clamping force presses the hollow shaft onto the shaft and creates a frictional connection at the contact surfaces between the shaft and the hollow shaft. Thereby, torque and/or axial force can be transmitted between the shaft and hollow shaft.

During the clamping process the position of the inner ring relative to the hollow shaft remains unchanged. The clamping is released simply by loosening the clamping screws, as the cone angles are self-releasing.

Torque-controlled assembly

The clamping screws are tightened uniformly in a clockwise sequence until the specified torque achieved (see Figure 5-2).

Insufficient or missing lubrication of the conical surfaces as might happen during servicing, results in a reduction of the radial clamping force. The torques or axial forces listed in the tables can no longer be transmitted reliably. This often goes unnoticed as the specified tightening torque was achieved during assembly and the assembly procedure is considered completed.

Technical Points for Shrink Discs

Shaft diameter dw

The values for the transmissible torques M or axial forces F given in the tables are calculated for exemplary shaft diameters sw. Values for shaft diameter dw that fall between the shaft diameters dw stated in the table can be determined with sufficient accuracy by interpolation. Please contact us for shaft diameters dw which are smaller than those given in the tables we will gladly calculate the transmissible torques M or forces F for you.

Axial width of contact surface LF

The transmissible of torque or axial force is achieved through the contact surface between shaft and hollow shaft. The pressure created by the Shrink Disc decreases strongly in areas that go beyond the bearing axial width L1 of the Shrink Disc. In such areas with low pressure, there may be micro movements that allow the formation of harmful fretting corrosion.

The axial width of contact surface LF should therefore be limited to:

LF ≤ 1.1*L1

For contact surfaces with a witch that is smaller than L1, there is an increased pressure generated which may damage the shaft and/or hollow shaft or the hub. Please contact us.

Joint clearance between shaft and hollow shaft

When the joint clearance the value given in the tables, the transmissible torque or the transmissible axial force decrease. Additionally, the equivalent stress in the hollow shaft increases in this case. Please contact us. If the joint clearance is lower than indicated the Shrink Disc, shaft or hollow shaft may be damaged during assembly or the torque listed in the tables can no longer be transmitted. Please contact us.

Friction Value

The values listed in the tables for transmissible torques M or axial forces F assume a function value of µ=0.15 in the contact surface between shaft and hollow shaft. The value is safely achieved in a dry and degreased steel/steel paring. For different friction values, the transmissible torque or axial force will change proportionally.

Simultaneous transmission of torque and axial force

The transmissible torque M which are shown in the tables apply for axial forces F = 0kN and conversely, the indicated axial forces F apply to torques M = 0 Nm. If torque and axial force are to be transmitted simultaneously, the transmissible torque and the transmissible axial force are reduced compared to the values listed in the tables for M and F.

For a given axial force FA, the reduced torque Mred is calculated as:

Mred=√M2-(FA*dw/2)

2

For a given torque MA, the reduced axial force Fred is calculated as:

Fred=2/dw√M2

- MA2

Bending moments

Where there is bending moments in addition to the torque MA or the axial force FA, the transmissible torque or transmissible axial force deceases compared to the values for M or F as listed in the tables. Please contact us.

Design and Function Cone Clamping Elements

Cone Clamping Elements as shown in figure 13-1 consist of an outer ring with

inside cone and inner ring with outside cone as well as a number of clamping

screws.

The outer ring is pulled onto the inner ring by tightening the clamping screws.

Radial clamping forces are generated by the conical surfaces which are dependent

on the torques of the clamping screws, the cone angle and the friction coefficient at

the screws and conical surfaces.

The radial clamping forces press the outer ring into the hub bore and the inner ring

onto the shaft and create a frictional connection at the respective contact surfaces.

In this way, torque and/or axial force can be transmitted between the shaft and the

hub.

In the configuration shown in the illustration, the connection is released by turning

some of the clamping screws into the threaded bores for the jacking screws. This

presses off the outer ring.

Centering the hub to the shaft

As a rule, a true running accuracy of the hub to the shaft of 0.02 to 0.04 mm can be

achieved with Cone Clamping elements of the series RLC 200. With these series

the hub must be centered to the shaft in accordance with the specific requirements

of the application.

No axial displacement of the hub relative to the

shaft during clamping

The series for which no axial displacement of the hub relative to the shaft is created

during the clamping procedure. This is ensured, for example, by a fixed hub

backstop point on the collar of the inner ring. For all other series, the clamping

procedure (tightening the clamping screws and pulling the outer ring onto the inner

ring) involves an axial hub displacement.

Hub Width and Hub Outer Diameter

Frictional shaft-hub-connections with Cone Clamping Elements create very high

radial clamping forces. This requires a hardness analysis of shaft and hub. For this,

the Cone Clamping Element tables list the maximum pressures pw in the contact

surface at the shaft and the maximum pressures PN in the contact surface at the

hub.

The contact pressure PW leads to radial stress in the shaft that is usually not critical

for steel shafts. There is always a tangential stress δt in the hub, and for thin-walled

hubs it may be a multiple of the initiated pressure PN. The amount of the actual

tangential stress depends on the load-bearing hub width N, the hub outer diameter

K and the pressure PN. Calculation of load-bearing hub width N takes into account

the fact that hub pressure PN is transmitted by load-bearing width L1 and taken up

beyond it in an angle of approximately 26.5°

For the different Cone Clamping Element series, the tables list the required hub

width Nmin and the required hub outer diameter Kmin for three exemplary yield

strengths Re of the hub. Thereby, the hub is to be arranged as seen in figure 15-1

for Cone Clamping Elements with a fixed backstop point.

For any deviating hub arrangement and/or lower yield strengths Re of the hub

material, the shaft-hub-connection must be verified according to the technical

points on pages 30 and 31.

Application example

Backlash free connection of a screw gear and simultaneous coupling of the divided

drive shaft of a continuous heating furnace with two Cone Clamping Elements RLC

110. A simple and cost-effective solution, because clamping the screw gear and

coupling the shaft ends is achieved simultaneously by the Cone Clamping

Elements.

Technical points for Cone Clamping Elements:

Clamping screw tightening torque

The tightening torque MS listed in the tables must be achieved during assembly and must not be exceeded by more than 10%. If the indicated tightening torque MS is not achieved, the transmissible torque or axial force, as well as the contact pressure at the shaft and at the hub will be proportionally reduced compared to the values listed in the tables for M or F as well for Pw and PN. When the indicated tightening torque MS is undercut by more than 30%, please contact us

Design security

On page 5, the RYDON calculation method for determination of the preload forces according to common friction–coefficient fluctuations is explained. As already shown there, the transmissible torques M and axial forces F listed in the tables are calculated based on the minimum preload force FS, where as the required hub outer diameters Kmin are calculated based on the maximum preload force MS assumed in the table are exceeded by 10%.

The calculation for the elements RLC 200, assumes that the preload force of the clamping screws provided by the customer is distributed accordingly.

In the interest of the best design security, the following assumptions were made for the calculation of the Cone Clamping Elements:

Simultaneous transmission of torque and axial force

The transmissible torque M which are shown in the tables apply for axial forces F = 0 kN and conversely, the indicated axial forces F apply to torques M = 0 Nm. If torque and axial force are to be transmitted simultaneously, the transmissible torque and the transmissible axial force are reduced compared to the values listed in the tables for M and F.

For a given axial force FA, the reduced torque Mred is calculated as:

Mred = √M2-(FA*d/2)

2

For a given torque MA, the reduced axial force Fred is calculated as:

Fred = 2/d√M2 - MA

2

Bending moments

Where there is bending moments in addition to the torque MA or the axial force FA, the transmissible torque or transmissible axial force is reduced compared to the values for M or F as listed in the tables. Please contact us.

Hollow shafts

When clamping Cone Clamping Elements on hollow shafts, the tangential stress δtWi must not exceed the yield strength Re of the hollow shaft material.

Hub Design

For the different Cone Clamping Element series, the tables list the required hub width Nmin and the required hub outer diameter

Kmin hub. Thereby, the hub is to be arranged as seen in figure 30-1 for Cone Clamping Elements with a fixed backstop point.

When the actual load-bearing hub width NA is smaller than the required hub width Nmin and the yield strengths Re of the hub

material is known, the calculated approximately as follows:

Kmin = 1.2 * D*

H = ( Re *

NA )2

1.27*PN L1

When the hub width NA is known and the hub yield strength Re must be higher than the equivalent stress δV in the hub.

δV = 1.27*PN* L1

* √3+CN4

with

NA 1-CN2

CN = D

KA The load-bearing hub width NA in the application must not be smaller than the load-bearing width L1.
