RX Series Single Stage Helical Gearbox with Foot Mounted
RX series helical gearbox is one type of R series single-stage helical gearbox with foot mounted. The transmission ratio of the R series helical gearbox is finely graded to meet different working conditions based on the customer’s need. R series helical gearbox realizes mechatronics, high transmission efficiency, and low energy consumption. It is mostly used in metallurgy, sewage treatment, chemical industry, pharmaceutical, and other industries. Shengjie’s R series gearbox is designed and manufactured on the basis of the modular combination system. There are many motor combinations, installation forms, and structural schemes.
