I. Overview

　　This product is a combination of spiral bevel gear transmission and planetary gear transmission. The NGW type planetary gear reducer including two-stage and three-stage series is mainly used for

　　Metallurgy, mining, lifting, transportation and general machinery and equipment.The applicable conditions are as follows.

　　1 The maximum speed of the high-speed shaft does not exceed 1500r/min:

　　2 Gear circumferential speed does not exceed 13m/s

　　3 The working environment temperature is 40℃-45℃-

　　4 It can move forward and backward, and forward clockwise is the preferred direction).
