WPS / WPA / WPO Worm Gear 
 WP-type worm reducer Archimedes, with a compact, easy installation, smooth and reliable, no noise (especially single-head worm), self-locking and so on. The reducer is widely used in mining, lifting, transportation, chemical industry, light industry and other industries in the relatively small device, the reducer for the following conditions: sliding speed of not more than worm 7.5m / s; high-speed shaft speed is not greater than 1500 r / min. Operating temperature is -40 ~ 40 ℃, can be both positive and negative to the operation. 

 1, the input shaft connection methods are the basic type (single-and dual-input shaft input shaft), 
 With motor flange two. 
 2, the basic structure of the output shaft type (single output shaft, dual output shaft) and hollow 
 Two output shaft. 
 3, output, input shaft position and direction of the next in the input shaft; output shaft 
 Up and down; input axis and down. 
 4, can be 2 or 3 sets composed of multi-stage gear reducer to get a great 
 Drive ratio
