Further machining of worm and worm wheels
Further machining of worm and worm wheels moderate power
The worms and worm wheels on pages 56-60 can be used whenever it is
not necessary to use high performance worm gear units. Every worm and
can be paired with every worm wheel of the same module. However, the
centre distance is different in each case.
Material: see data pages 56-60
Further machining
The following clamping methods are recommended:
Installation
For worm and worm wheels, in general, proceed as suggested on page 170
Installation advice see page 174
Lubrication
The most suitable lubrication is to be determined from case to case.
Grease lubrication is adequate for manual operated drives and small rpm’s.

Worm wheels with machined hubs can be
clamped here.
Cast iron wheels without machined hubs are
to be held by mandrel, and the hub is to be
machined, thereafter it can be clamped on the
hub to machine the bore.
Worm tooth (or teeth) is machined concentric
to the bore.
Worm shafts are centre drilled. It is therefore
advisable to take them up on the centres.
