General Description |
VC design and construction is different from the CB and CM elements in that the torque is transmitted by torque bars rather than the sidewalls of the actuating tube. 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. Element torque capacity is dependent upon the applied pressure and rotating speed. Catalog ratings are given at 75 psi (5.2 bar) and zero rpm. Maximum recommended pressure is 125 psi (8.6 bar). Adjustment for pressure and speed is explained under Selection Procedure. |
Part Number refers to basic part number only. When ordering, the number of air inlets and type of connection must be specified.
1 Maximum rpm is dependent upon operating conditions and varies for each application. Consult factory for applications exceeding these speeds.
