Force transmission control device for hoisting engine, has eccentric disks, with same radius, coupled by coupling sleeve driven in continuous circular movement of coupling rod by guiding system guided by constant velocity joints

摘要

The device has a driveshaft (1) acting on eccentric disks (A, B), after a slight angular clearance during a change of two directions of a transmission of a couple of forces, where the disk (B) has a journal (2). The disks have the same radius and are coupled by a coupling sleeve (3) driven in a continuous circular movement of a coupling rod by a guiding system guided by constant velocity joints. The joints are supported on the opposite vertical walls of a fixed chassis-case (C) and are composed of lateral fingers originating from a circumference of the two sides of the sleeve.
