技術要求：     1.配合間隙選配：徑向為0.05-0.08mm，軸向游隙為0.08-0.15mm。     2.離合器傳遞扭矩≥250N.m。     Technical requirements:     1. Matching clearance selection: radial clearance is 0.05-0.08mm, and axial   clearance is 0.08-0.15mm.     2. The clutch transmits a torque of ≥ 250N.m.

本系列離合器主要適用于小型高速電機。小高速電機離合器，在運行時，它可以很好的軸向和徑向定位。

具有運轉平穩，摩擦力小，基本無噪音等特點。

徹底解決了三滾柱離合器的定位不好，運轉時左右擺動容易損壞行星架齒輪的缺點，大大提高了整機的使用壽命。其靜態扭矩達220N.m。

This series of clutches is mainly suitable for small high-speed motors. The small high-speed motor clutch can achieve good axial and radial positioning during operation.

It has the characteristics of smooth operation, low friction, and basically no noise.

Thoroughly solving the problem of poor positioning of the three roller clutch and easy damage to the planetary carrier gears due to left and right swinging during operation, greatly improving the service life of the entire machine. Its static torque reaches 220N. m.
