Helical worm gears - Import export

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.

Housing aluminium. Worm screw steel, worm wheel special brass. Version Housing anodised. Ball bearing with rubber sealing washer RS. Note Universally applicable and maintenancefree worm drive in one size with a centre distance of 20 mm and 7 different ratios. The housing is sealed to prevent grease leakage and keep dust out. These are left hand worm gears. The rotation direction on the shaft is arbitrary. smooth power transmission simple screw fastening quiet Note FR permissible radial force at FA=0 FA permissible axial force at FR=0
