Planetary Gear Reducer
The involute planetary gear reducer has begun to be adopted in domestic mine hoist drive system since the early of 1980s. Because of a series of advantages such as small size, light weight, great bearing capacity, high drive efficiency, stable running and so on, the involute planetary gear reducer becomes more and more popular among the users so that share of the market has expanded gradually. The involute planetary gear reducer is driven by single motor, adopting for single rope winding mine hoist and multi-rope friction mine hoist. According to the gear ratio requirements of reducer by mine hoist, the tactic forms of involute planetary gear reducer are divided into two types of single-stage derivative planetary gear drive (prepose a first-stage parallel-axes gear for drive) and two-stage planetary gear drive.
