All gearbox applications of worm, helical, bevel&planetary types

Gearbox specialized for fire grate

1. Overview of WT type gearbox specialized for boiler：

The product is novel structure, compact installation, small size, light weight, high efficiency, low noise, long life, widely usage,etc. It is the replacement of  1 ~ 40T / h chain grate boiler drive device. Our products passed the provincial appraisal in 1996, won provincial science and technology achievement award in 1997, and it was named the provincial excellent new product in 1998.

The transmission power is offered by electromagnetism speed regulation motor

2. Structure Characteristics of WT type gearbox specially used for fire grate:

(1) This product uses the involute gear planetary transmission (NGWN structure), to reduce the tooth surface load, to extend the service life of gear, power split mechanism and with the characteristics of floating uniform loading.

(2)Adopted electromagnetic speed motor and controller (also can be equipped with frequency conversion motor and frequency changer, etc. according to requirements.), obtained a smooth variable speed, the wide speed range can accommodate to different loads under the grate speed.

(3) high accuracy of the transmission, reliable performance, stable quality, easy to use, and easy maintenance.

(4) small size, high efficiency, noise less than 75 decibels. Tightness, and equipped with overload safety system.

(5))Adopted The oldham coupling with features such as easy installation alignment.
