Compared to general speed reducers, motorized pulley drum got smaller volume, lighter weight, better sealing and easier to be dis-assembled. It can be used in such environment as heavy powder, muddy, wet and outdoors. The operating ambient temperature is -10℃ to +40℃. And usually it isn’t used at altitude over 1000m.

 

The motorized drum we produce includes three types - the cycloidal pin wheel, the fixed-shaft gear one, the planetary gear one. The installing form includes motor-inside, motor-outside and mobile one. There are ten series of them, YD, DY1, JDY, QD, YBT, JAT, JXT, WDT, WBT, WXT. All the products can be glued, the glue face can be classified into planar glue, herringbone-type glue and and rhombic glue. The whole motorized drums except DY1 and JYD series can be equipped with back-stop parts. There are oil-cooling type and oil-immersed type when motor-inside, and when motor outside of the drum, could realize motor-horizontal type, motor-vertical type and horizontal vertical type. The motor is assembled with Y2 series motor, explosive-proof motor is available when necessary. In additional, HL-type elastic pin coupling, YOX-type hydraulic coupling and YWZ-type hydraulic-pressure block brake could also be provided with drums.
