2Input and output shaftProduct description

2.12.7 Output shaft as a splined hollow shaft /..VThe output shaft is a splined shaft according to DIN 5480.

Included in the scope of delivery:

End plate with screws [1], or 2 retaining rings and protection cover [2].

2.12.8 Gear unit mounting with hollow shaft gear unitsDue to the rigid connection between the machine shaft and hollow shaft of the gear unit,constraining forces can occur on the output shaft bearing.

This is why you have to observe the following points when mounting hollow shaft gearunits:

• The gear unit is usually foot or flange-mounted and used as bearing point when themachine shaft has no individual bearing or merely provides one bearing point. Youhave to provide for an accurate coaxial alignment with the bearing point.

• If the machine shaft has at least two bearing points, the gear unit should be con-nected only to the machine shaft and supported with a torque arm. In order to preventexcess stress on the bearing, gear units with foot or flange mounting are to beavoided.

8593160843[1]

[2]



The protection cover is dust-proof, see previous page.

INFORMATIONNon-observance may result in damages to the output shaft bearing and increased fret-ting corrosion in the connection between the machine and the hollow shaft of the gearunit.

2 Storage and transport conditionsProduct description

2.16 Storage and transport conditionsThe gear units can be provided with the following protection and packaging types de-pending on the storage and transport conditions.

2.16.1 Internal conservationStandard corro-sion protection

After the test run, the test oil fill is drained out of the gear unit. The remaining oil film pro-tects the gear unit against corrosion for a limited period of time.

Long-term corro-sion protection

After the test run, the test oil fill is drained out of the gear unit and the interior space isfilled with a vapor phase inhibitor. The breather filter is replaced by a screw plug and en-closed with the gear unit.

2.16.2 Exterior corrosion protectionThe following measures are taken for exterior corrosion protection:

• Anti-corrosion agent is applied to bare, non-painted functional surfaces of shafts,flanges, mounting and foot surfaces of the housing. Remove it only using an appro-priate solvent which is not harmful to the oil seal.

• Small spare parts and loose pieces, such as bolts, nuts, etc., are packed in corrosionprotection plastic bags (VCI corrosion protection bags).

• Threaded holes and blind holes are covered by plastic plugs.

M1 = Initial mounting positionM4 = Pivoting direction9° = Fixed pivoting angle

Pivoted from mounting position M1 to M4 by 9°.

2.25.2 Variable pivoted mounting position Definition: Gear units with variable mounting position can change the mounting position variably

during operation within the specified max./min. range.

Example: The gear unit is operated in variable pivoted mounting position M1 to M6 = 9° and M1 toM5 = 12°.

Step 1: The largest pivoting angle determines the positive pivoting direction (12° > 9°). In thisexample, this is 12° towards M5.

12° → pivoted from M1 to M5 by +12°

9° → pivoted from M1 to M5 by -9°

The variable pivoted mounting position is shown on the nameplate as follows:

Step 2:For variable pivoted mounting positions, the customer must determine the pivoting anglein which the oil level is checked.

An additional nameplate is used to clearly indicate the oil check angle. This nameplatelists the mounting position for the oil level check.

2.25.3 Combination of variable and fixed pivoted mounting positions

Fixed and variable pivoted mounting positions can be combined.

Example: The following example describes a combination of fixed and variable pivoted mountingpositions according to chapters 3.5.1 and 3.5.2.

The type designation is set up as follows:

The variable and fixed pivoted mounting position is shown on the nameplate as follows:

When combining fixed and variable pivoted mounting position, the customer must deter-mine the variable pivoting angle in which the oil level is checked. The fixed angle for theoil level check is already defined.

The gear unit has an additional nameplate to ensure correct oil level checks. This name-plate lists the mounting position for the oil level check.

M1 = initial mounting positionM4 = pivoting direction9° = Fixed pivoting angle

M1 = initial mounting positionM5 = pivoting direction12° = 12° from M1 to M5 –9° = –9° from M1 to M5 (= 9° from M1 to M6)
