HGR speed reducer

螺旋傘齒輪設計，精密研磨齒輪，齒面平滑精度高。

高容許輸入轉速。

直角齒輪箱採用高強度鋁合金設計，使輕量化。

Features

Smooth operation and low noise

The pinion and rack are fitted with a helical system and are hardened and precision ground.

Easy to install, space-saving and weight-saving

The pinion is connected to the hollow shaft of the reducer by a high-strength and tough coupling.

The reducer can withstand large load axial/radial thrust.

The reducer output shaft is equipped with a set of high-strength tapered roller bearings.

The pinion and rack can be adjusted to optimal precision.

The structure is simple and the position of the pinion is easy to adjust thanks to the eccentric connecting plate.

High starting performance and short acceleration time

Excellent structural design achieves low moment of inertia and sensitive start-up and stopping.

High economic benefits

Due to its low moment of inertia, a smaller servo motor can be selected, saving costs.

Excellent linear positioning accuracy

The pinion and rack are made of ground-grade products, and the cumulative pitch error accuracy of the rack is 0.03/1000mm.

Long lifespan
Combining the following overall synergies

European standard design structure
Selected bearings from renowned Western European brands
German-made oil seal
The gears are hardened and precision ground.
High protection index oil lubrication
