SL cross slider coupling
Summary:SL type cross slider coupling is also called floating disc coupling, which has a simple structure and a long history of use.It allows large radial relative displacement and large transmission torque, but due to the intermediate sliding block, the starting inertia is large, and it cannot be used at high speed. Generally, the shaft speed does not exceed 300r/min.
Main features of SL cross slider coupling:
SL type cross slider coupling is also called floating disc coupling, which has a simple structure and a long history of use.It allows large radial relative displacement and large transmission torque, but due to the intermediate sliding block, the starting inertia is large, and it cannot be used at high speed. Generally, the shaft speed does not exceed 300r/min.
The two half-couplings are each provided with a radial through groove. When the axes of the two connected shafts have a relative radial displacement, the tenon of the cross slider can slide in its corresponding groove. Due to the wear of the cross groove, And the transmission efficiency is reduced.
