Worm gearboxes ZAP
Application: Worm gearboxes type ZAP with motor, without motor are assigned for speed reduction of the input unit onto the input speed of the output unit by a constant ratio.
The use of these gearboxes is applicable at places where from their small size are required large gear ratios, smooth and silent running and a relatively large power output. The gearboxes can work in all positions.
Description:The gear ratio of the basic unit is executed through a worm gear. The gearboxes are delivered:
- with motor and without motor
- with single, double or hollow shaft
- with feet, flanges or without them
Gearboxes with elektromotor are using a three phase asynchronous motor with a short-circuit armature, type 4AP or with a break 4APB, with IP 54 protection - closed with own surface cooling, model number IM 3681. The motor is usually delivered for voltage of 380 V/50 Hz. The housing and the feet are from grey-cast iron.
