Abstract

The invention relates to a synthetic friction belt for a switch machine and a manufacturing method thereof. It uses cashew nut shell oil modified phenolic resin as a binder. Strong binding ability; the present invention uses NFJ non-rusting lightweight foam fiber with a carbon content of less than 0.02% as one of the reinforcing fibers, which has rough surface, loose, porous, strong plasticity, no rust, noise reduction, etc. Advantages; the present invention uses carbon fiber powder as a kind of reinforcing phase, which has high strength, low density and strong corrosion resistance; the present invention uses stabilized heat treatment to improve the heat dissipation of the material, regulate the porosity of the material, and improve the hardness and Anti-shear performance; the invention has simple process, low energy consumption, good material uniformity, high mechanical strength, strong toughness, good thermodynamic performance, stable friction coefficient, good thermal stability, excellent durability and reliability, and low wear Rate.

Description

technical field [0001] The invention relates to the technical field of transportation materials, in particular to a synthetic friction belt for a switch machine and a manufacturing method thereof. Background technique [0002] With the progress of the times, high-speed rail trains have appeared more and more in people's lives, and people have deeply realized the convenience brought by high-speed trains, and more and more people have begun to choose trains to travel. However, with the popularization of motor trains, people pay more attention to its safety factor, and the switch machine is one of the important guarantees for the safe running of the train. The friction coupling plays an important role in the electric switch machine. It is a coupling device for motor drive, protection motor and absorbing moment of inertia. Its main functions are three: one is to ensure the stable output of the torque of the transmission part during the normal conversion process of the switch ma...
