Performance, characteristics: 1. There are two types of input shaft connection: basic type (single input shaft and double input shaft) and motor flange. 2. The output shaft structure has basic type (single output shaft, double output shaft) and hollow output shaft. 3. The position direction of output and input shaft has input shaft down and up; output shaft up and down; input shaft up and down. 2 or 3 reducers can be used to form a multi-stage reducer to obtain a great transmission ratio. : Worm gear reducer is widely used in metallurgy, mining, lifting, transportation, chemical industry, construction, ceramics, cold rolling, bending officer, entertainment and other mechanical equipment deceleration transmission.
