Precision worm centre distance 31mm i=12 PN: 32111200

Material: Steel 11SMnPb37 (1.0715), inspected for fissures, case
hardened HV 620-700, ground. Pressure angle 15°. The worms can only be
used with gear wheels 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, since – besides the lead angle – also mounting,
lubrication, speed and assembly have an influence on the efficiency.
