Extension Shaft Mounted Gear Speed Reducer with high torque
Product structures and characteristics
ZJY series axial speed reducer uses installation of directly hangs from supporting main machine power input shaft, and leaves out construction platforms of conjoined accessories and speed reducer between them. It is appropriate for bucket elevator, belt conveyor, scraper conveyer, and other devices’ mechanical transmissions. It can fit with other main engines that have this installation requirement as well.
Products are manufactured according to FB／T9095.1—1999 standard. The driving parts use superior alloy steel material. Gears are processed by cemented quenching and gear grinding technology. Precision is GBl0095—88, six-grade. The product is small in size, with high bearing capacity, long life, low noise and high efficiency. Compared with ZJ series axial speed reducer, with same output torque, the weight of ZJY is just about 30％ of ZJ. Therefore it reduces the demand for rack rigidity of supporting main machine, drive smoothly. Besides two-way operation, products can be equipped with back stop device according to user’ needs, to realize one-way braking.
Product model and label
All series speed reducers take slow speed center distance (MM) as unit, altogether75、90、106、125＼150、180、212、250、300 specifications. transmission ratio of every specification has nine kinds, including 10、11、2、12．5、14、16、18、20、22、4、25.
Standard designations of speed reducer include model, slow speed center distance, nominal transmission ratio and direction of turning.
