Abstract

The invention provides a wet copper basic powder metallurgy friction disc and a manufacture method. The friction disc mainly consists of a middle steel core plate and at least a side upper friction layer; at least one surface of the steel core plate is combined with a rubber film layer which is composite with a friction layer; the manufacture method at least comprises friction layer material distributing, mixed material, pressing-typed, burning, assembly with the steel core plate, and oil trough processing. The invention is characterized in that no pressure burning in a continuous burning furnace is adopted for burning; the friction layer after burning is dipped in rubber in a vacuum rubber dipping trough in normal temperature and is dried and assembled with the steel core plate; before the assembly, the surface of the steel core plate is coated; after assembly, the pressurization and solidification are carried out on a slab vulcanizing machine; the invention has the advantages of high efficiency of processing technique, low cost, increasing the hardness and strength, high size precision, etc.

Description

technical field [0001] The invention relates to a transmission friction plate and a manufacturing method, in particular to a friction plate and a manufacturing method for a transmission clutch made of copper-based powder metallurgy. Background technique [0002] The friction plate is one of the most important parts in various mechanical equipment. They use friction to work. To work reliably, the friction plate must have a sufficiently high and stable friction coefficient, high wear resistance, heat resistance, and high mechanical strength. , will not bite to death with the dual piece. The friction plate can be divided into metal, fiber reinforced resin base, such as asbestos, semi-metal, non-asbestos, paper base, carbon base, or powder metallurgy friction material according to the material. Powder metallurgy friction materials are widely used due to their high heat resistance, friction coefficient and wear resistance under various working conditions. The application range ...
