Attachment of drive elements
The mode of balancing of drive elements must be adjusted to the motor. Refer to
the notes regarding the installation of drive elements.
Motor damage by intrusion of liquid!
CAUTION
Pending liquids (e.g. cooling lubricants, gearbox oil, etc.) at the drive shaft are
inadmissible.
When installing gearboxes please use gearboxes with closed (oil-proof) lubrica-
tion system only. Gearbox oil should not be in permanent contact with the shaft
sealing ring of the motors.
Gearbox mounting on motors
Observe the instructions in the corresponding manufacturer´s documentation.
Over-determined bearing
When installing drive elements, avoid overdetermined bearing, as impermissibly
high bearing reactions can be generated due to unfavorable bearing ratios.
If an overdetermined arrangement of bearings cannot be avoided,
please contact Bosch Rexroth.
Couplings
The machine construction and the drive elements used must be carefully adap-
ted to the motor type so as to make sure that the load limits of the shaft and the
bearing are not exceeded.
When extremely stiff couplings are attached, the revolving radial
force may cause an impermissibly high load on the shaft and bear-
ing.
Bevel gear pinion or helical drive pinion
Due to thermal expansion, the DE side of the drive shaft can be displaced by up
to 0.6 mm in relation to the motor housing. If helical drive pinions or bevel gear
pinions directly attached to the output shaft are used, this change in position
will lead to
●
a shift in the position of the axis, if the driving pinions are not axially fixed on
the machine side,
●
a thermally dependent component of the axial force, if the driving pinions are
axially fixed on the machine side. This causes the risk of exceeding the maxi-
mum permissible axial force or of the gear backlash increasing to an imper-
missible degree.
