Helical Driving Pinion
Owing to thermal effects, the end of the output shaft may shift up to
0.6mm in relation to the motor housing. If helical or spiral-bevel driving
pinions are directly attached to the output shaft are used, this change in
position will lead to
•
a skewing of the bearing of the driven axis.
Note:
The direct attachment of helical driving pinions is not allowed
in general. If helical driving pinions have to be used then only
drive elements with their own bearings may be used that are
connected to the motor shaft via axial-balancing couplings!
Bevel Gear Pinion
Owing to thermal effects, the end of the output shaft may shift by 0.6 mm
in relation to the motor housing. If bevel gear pinions are directly mounted
to the output shaft, this change in position will lead to
•
a thermally dependent component of the axial force if the driving
pinions are axially fixed on the machine side. This could allow the
maximum permissible axial force to be exceeded or for the backlash
within the mesh to increase to an impermissible degree.
For this reason, bevel gear pinions may not be attached directly to the
motor shaft. If bevel gear pinions have to be used then only drive
elements with their own bearings may be used and these must be
connected to the motor shaft via axial-balancing couplings!
Note:
The direct attachment of bevel gear pinions to the motor shaft
is not allowed.
