Material: Special brass CCuZn37Mn3Al2PbSi/So. Pressure angle 15°.
The gear wheels can only be used with worms having the same centre
distance and the same transmission. Can be built into gear systems, no
reworking required, thus short assembly times. ** The figures stated for
the efficiency are only reference values, as besides the lead angle,
also mounting, lubrication, speed and assembly have an influence on the
efficiency.
