UNIVERSAL JOINT USED FOR SHAFT TRANSMITTING TURNING MOMENT, PARTICULARLY, CARDAN SHAFT, AND PARTIAL DRIVING SHAFT

摘要

PURPOSE: To reduce the wearing in the bearing portion by arranging a slip layer of the retraining roller for raising the slip property at the inner side of the slide bearing bushing rotatably supported on the entraining journal. CONSTITUTION: A spherical basic component supporting a slip layer 17 is on the back layer of a slide bearing bushing 16. The slip layer 17 deposited on the basic component has a matrix made of polyether-etherketone. The matrix is deposited in the hollow space of the basic component. Graphite short fibers are deposited inside the matrix. These short fibers have a length shorter than about 1 mm and a diameter of about 0.005-0.03 mm, comprising 10-45% of the total weight of the slip layer 17. PTFE granular of a granularity of 40 μm are deposited in the matrix as an additive for improving the slip property.
