Gearbox HG

此減速機為獨特中空軸設計，輸出端可裝置較少齒數齒輪，伺服馬達可選用較小規格，獲得最小啟動扭矩，達到高經濟效益。HG系列榮獲台灣精品獎項肯定。

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
