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.

The new direct-current motors with worm gear enable quiet and economically efficient operation with drylin® lead screw units. The worm wheel has a spline to which the drive pin of the linear unit is connected. As a result, a motor flange and coupling are unnecessary and, this taken in conjunction with the motor adapter angled by 90°, the structure of the linear module is very compact. Thanks to the integrated magnetic rotary encoder (2-channel hall), the new DC motors are suitable for positioning. - Space-saving and compact design - Easy to fit - Quiet operation - Rotary position encoder included - Suitable for: SLW-BB, SAW, ZLW

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

Base and rotary table aluminium alloy. Hollow shaft stainless steel. Preloaded worm gear steel. Claw coupling aluminium with polyurethane coupling spider. Version Aluminium alloy anodised. Note for ordering The unit is supplied with the position of cable outlet or control unit as shown in the drawing. Note Rotary positioning stages for motorised adjustment and positioning tasks. The preloaded worm gear runs virtually playfree. The bearing of the worm shaft offers maximum radial rotational accuracy. Cables can be routed through the large bore in the hollow shaft. The adjustable positioning ring is used to determine the rotational reference point to the position of the assembled part. Proximity switches can be mounted with the optionally available sensor holder (21094). The suitable programming software and interface cable for the stepper motor with positioning control are available as accessories (2500015).
