Make an order
Cylindrical-worm gearbox CH (CH-40, CH-50, CH-63, CH-80, CH-100, CH-125, CH-160, CH-200) is designed for horizontal or vertical installation (shaft down) as a general purpose drive.
This is a two-stage gearbox, in which the cylindrical gear is high-speed, and the worm gear is low-speed. The longitudinal axes of the motor shaft and the output shaft form a right angle, which enables a convenient location of the drive. The leading gear wheel mounted on the motor shaft transmits the rotation of the gearbox. Cylindrical-worm reducers are an effective technical solution for the improvement and replacement of typical one- and two-stage worm reducers (CH, 2CH, CH2 series).
Terms of use:
- operation in S1 mode (according to GOST 183-74) with a duration of 8-24 hours/day;
- rotation of output shafts – in any direction;
- external environment – non-aggressive, non-explosive with non-conductive dust content up to 10 mg/m3;
- climatic execution of U;
- placement category 3 according to GOST 15150-69 when working at an altitude of up to 1000m above sea level.
