Gear reducer | Planetary gear reducer

Gear reducer | Planetary gear reducer

Achieves high driving force and precise positioning with a high-precision, high-rigidity planetary gear reducer. By switching to reinforced bearings, it is possible to increase the allowable axial and radial loads.

Stover's planetary gear reducer achieves high precision, high rigidity, and high efficiency through technologies such as helical gears and internally geared components that are integrally molded with the housing. By using four planetary gears, it offers a lineup of coaxial types ranging from the PHQ/PHQA type, which has very high torque, precision, and rigidity, to the economy type PE. Additionally, by combining with bevel gears, an orthogonal axis type is also available. 【Features】 ■ Improved positioning accuracy with high precision and high rigidity ■ A wide variety of shafts, outputs, and reduction ratios available ■ Possible to change to reinforced bearings (axial and radial) ■ Maintenance-free with no need for lubrication oil replacement

Compower planetary gear reducer

Compower planetary gear reducer

A high-torque yet compact radial planetary gear reducer. The overall length has also been significantly shortened.

**Features** 1. Rich Variety of Models By adopting a modular design, we have accommodated many specifications with a minimal number of components. • A wide range of output torque from 0.46 to 736 kN·m and input power from 0.2 to 1200 kW is available in the series. • Gear ratios from 5 to 1400 are supported. • Compatible with foot mounting, flange mounting, and shaft mounting (optional). 2. Drive Unit A motor direct connection type (drive unit) is available in the series. Since the reducer and motor are integrated, the layout of the equipment is simple. Complicated motor alignment and base plate fabrication are unnecessary, which reduces installation labor. 3. High Strength and High Rigidity Planetary Gear Mechanism Multi-stage planetary mechanism: The multi-stage planetary gear system and our unique equal distribution structure optimally distribute the load acting on each gear. It allows for large torque transmission with a slim outer diameter. High pressure angle gears: By adopting a maximum pressure angle of 27°, the bending strength at the tooth root of the gears is significantly improved, resulting in a design that is strong against shock loads.
