ZSY160 Three-Stage Gear Reducer: Complete Technical Parameters


H1: ZSY160 reducer - technical parameters and selection information

Technical parameters of ZSY160 three-stage hard tooth cylindrical gear reducer: ratio, torque

 capacity, speed limit, size, and rated power listed in physical data

H2: Rated power of ZSY160 reducer gearbox (based on transmission ratio and input speed)

The nominal input power (P₁) varies substantially with ratio and input speed. At the lowest ratio (22.4) and 1500 r/min, ZSY160 is rated at 67 kW; as the ratio increases toward 100, the permissible input power falls because the required output torque rises at lower speeds.
