EATON Airflex VC Clutch Twindisk
Overview
VC clutch is transmitted by torque bars. The loose actuating tube is contained within a housing formed by a rim and two side plates, and is replaceable. The torque bars, which are held in position by the side plates, pass through cavities in the backing plates of the friction shoes. Pressurizing the actuating tube forces the friction shoes to engage around a cylindrical drum. Leaf springs in the torque bar cavities of the backing plates retract the friction shoes when the actuating tube pressure is released.
Torque up to 13,877,000 lb.in / 1,567,000 N.m
