BEGE Helical Gear Motors – Type G & M Lubrication

Lubrication

These lubricants are for ambient

temperatures from -5°C to +40°C The lubricant quantity responds to the mounting

position shown on the name plate and depends on

gear size and mounting position.

Special lubricants: • For extreme low temperatures -40°C to 0°C

• A non toxic lubricant for the food processing

industry, certified to USDA H1 standard

• Further special lubricants on request

Standard lubrication G-series: Mineral lubricant ISO VG220

Standard lubrication M-series: Synthetic lubricant VG460

BEGE Helical Gear Motors – Type G & M 4-stage gear units

4-stage gear units

The 4-stage gear units are designed using two basic 2-stage gear units: • The primary gear unit is always a flange mounting gear unit

• The secondary gear unit can be a foot- or flange mounting gear unit. This depends on the mounting position

Lubricants The lubricant quantities for the 4-stage gear unit can be selected from the same selection table but now specified as primary

and secondary gear unit.

Example:

4-stage gear unit (DS)G55-26 mounting position B3:

Primary gear unit G26 : 0.5 liter

(Always flange mounting so use B5 lubricant quantity)

Secondary gear unit G55 : 4.7 liter

BEGE Helical Gear Motors – Type G & M Efficiency

Gears selection

The correct choice of gear unit starts by determining the required torque. The gear selection lists specify for the respective output drive speed n2 and the theoretical output torque T2n

The power rating of the motor P1n to be installed can then be chosen (include safety margin)

Helical gear motors have a very high efficiency Generally the efficiency for each gear stage is 0,98 < η > 0,95 and 0,95 < η > 0,90 for a gear stage with oil seals

Our experience shows that;

• The total efficiency for a 2-stage gear is η = 0,90

• The total efficiency for a 3-stage gear is η = 0,86

BEGE Helical Gear Motors – Type G & M Criteria

Gears selection

Criteria We recommend consulting with us regarding the operation in detail if two or more of the following points apply:

• Vertical arrangement (mounting position V5 and V1 or V6 and V3)

• Ratio i < 20 helical gear drive

• Drive speed n1 > 1500 min-1

• High ambient temperature > 40°C

• Specific installation conditions apply e.g. gear enclosure, radiated heat, restricted installation space, etc.

BEGE Helical Gear Motors – Type G & M Load type

Drive design Certain details such as motor power, output speed, output torque etc. Are necessary for configuring the drive.

To match the operating conditions the service factor fb needs to be determined.

BEGE Helical Gear Motors – Type G & M Service factor

Gears selection

Drive design Certain details such as motor power, output

speed, output torque etc. are necessary for

configuring the drive.

To match the operating conditions the

service factor fb needs to be determined.

The service factor has to be multiplied by:

• 1.2 for the application with a combustion

wengine drive, with reversing operation and

winstantaneous overloads

• 1.5 for the application with a brake motor

BEGE Helical Gear Motors – Type G & M Radial load at the output shaft

Gears selection

Drive design The radial load at the output and input shaft which is caused by

transmission elements can be calculated with the following formula:

FR2 = Radial load [N]

Td = Torque of the shaft [Nm]

fz = Transmission element factor

fb = Service factor

dw = Mean diameter of the transmission element [mm]

Changing the rotation direction, the loading

direction, or the use of reinforced bearings, can

result in a higher permissible radial load FR2max

BEGE Helical Gear Motors – Type G & M Axial load at the output shaft

Gears selection

Axial load The permissible axial load is 50% of the permissible radial load FR2max.

(The permissible axial and radial load may be applied simultaneous on the output shaft)

Reinforced bearings If the permissible radial/axial load is not sufficient, it is possible to apply reinforced bearings

for the output shaft at additional cost.

If the axial load is higher then the permissible axial load, please contact BEGE

BEGE Helical Gear Motors – Type G & M Maximum permissible radial load on the output shaft

Gears selection

Maximum permissible radial load The permissible radial load effected on the output shaft is given in Newton [N]

The G-series it depends on the power and speed

The M-series it depends on the gear unit size and speed

n2 : Speed of the output shaft [min-1]

P : Power [kW]

BEGE Helical Gear Motors – Type G Maximum permissible radial load on the input shaft

Gears selection

Maximum permissible radial load The permissible radial load effected on the input shaft is given in Newton [N]

Pay attention to radial force when;

• Transmission by v-belt or chain

BEGE Helical Gear Motors – Type G Gear motor with IEC-adapter

Gears selection

IEC-adapter The gear motors can be delivered with an IEC-adapter.

Thereby any motor can be installed with an IEC standard flange (oil sealed motor required)

Advantage: Install a patented magnetic pulse encoder (MIG), which is implemented as an intermediate flange.

With the combination of IEC gear unit / MIG / 3-Ph motor it’s possible to implement a gear motor for;

• Frequency controlled positioning

• Dosing control

• Torque control

• etc.

The mechanical connection between motor and gear is achieved via a toothed coupling (included)

BEGE Helical Gear Motors – Type G Gear motor with IEC-adapter

Gears selection

IEC-adapter The gear motors can be delivered with an IEC-adapter.

Thereby any motor can be installed with an IEC standard flange.

• Simple installation and dismantling

• No frictional corrosion

• Compact design

• Cost effective spare parts

• By using different bores in the toothed coupling, it’s

kpossible to fit different sized motor frames to each gear

BEGE Helical Gear Motors – Type G & M Motors

per hour) of a motor is calculated from the switching

frequency specified in the data list:

A : Max. switching operation (with load)
