Worm gears - Import export

Offered for drive systems with low moments and regular loads, worm gear units stand out with their light, modernly designed bodies with high strength, as well as silent operation.

Helical and worm gear units with 90° input and output axis range. Casing with feet, flange F options Rigid case structure and suitable for heat transfer. System resistance calculations are made in accordance with ISO, DIN and NIEMANN standards. Different input options may be provided (Coupled motor, IEC, PAM, W, Servo motor connected, ...). Different output options available (Solid shaft, Hollow shaft, With shrink disc, ...).

Worm screw steel. Worm wheel CuZn37Mn3Al2PbSiS40. Version Worm screw with righthand pitch, casehardened HV 620 – 700, flanks and hole ground. Note for ordering Wheels/screws can only be combined to form a worm gear if they have the same centre distance and transmission ratio. Note A worm gear consists of a worm screw (shaft) and a worm wheel. Suitable for forming worm drives with a 90° shaft angle. A worm drive enables very large speed reduction ratios with a single stage. The toothing has the flank shape K. The engagement angle is 15°. The worm gears are prebored. The stated T2 output torques are the permissible output torques on the worm wheel. These apply for an input speed of 2800 rpm of the worm screw. The worm gears are suitable for continuous operation at high speeds and high torques. Attention 22500171002 Screw polished only. 22500172002 Worm wheel with helical gear toothing.
