The output elements shall not transmit to the gearbox radial loads FR and axial FA exceeding
the maximum permissible value. In particular, for belts and chains it is necessary to respect the
correct tension.
No additional load due to unbalance of hubs is permitted.
Radial loads shall be applied as close as possible to the gearbox.
7.7
Mounting of plug-in gearboxes
If the reaction arm screw loosens, the gearbox can beat against the output shaft
Lock the screw connection to prevent loosening, for example with Loctite 242 or
a second nut.
Damage to gearbox caused by axial forces.
In the event of improper assembly, bearings, gear wheels, shafts and carcases
could be damaged.
-
Use suitable shrink disks.
-
Don’t beat on the
gearbox with a hammer.
To simplify assembly and subsequent disassembly, apply an anti-corrosion lubricant to the shaft
and hub before assembly. Excess grease or anti-corrosion may leak and drip after mounting.
After a break-in of about 24 hours, thoroughly clean the points on the output shaft. The grease
leak does not constitute a loss of the gearbox.
