Features

Features

 N/AOne-Piece Gearbox Housing
齿轮箱和内齿圈是一体式结构。高齿轮精度符合DIN6课程。

满滚针轴承的设计
The planetary gear transmission employs full needle roller bearings without a retainer to increase the contact surface that maximizes structural rigidity and service life.

夹紧机构
The input-end and the motor are coupled through a collet locking mechanism that ensures concentricity and balance on the connection and no backlash for power transmission while running at high speed.

Integrated Planetary Arm Bracket
The planetary arm bracket and the output shaft are one-piece constructed to increase torsional rigidity and accuracy. The entire structure is machined for controlling accuracy in the specified tolerance.
