Abstract
The utility model relates to a friction plate, especially to a loader copper-based powder metallurgical friction plate. The friction plate in the utility model comprises a steel disc the center of which is provided with an assembling hole. The edge of the assembling hole is provided with sleeve key teeth. The front face and the back face of the steel disc are respectively provided with a copper-based layer. The surfaces of the copper-based layers are provided with end-breaking grooves and spiral grooves. The spiral grooves are equipped between the end-breaking grooves. The loader copper-based power metallurgical friction plate in the utility model has the advantages of simple structure, high heat radiation, assembling convenience and long service lifetime.
Description
Technical field
The utility model patent relates to a kind of friction plate, relates in particular to a kind of loader copper based powder metallurgy friction wafer.
Background technique
At present traditional friction plate assembly performance is poor, and assembly precision is not high, and friction factor is low simultaneously, and the product loss is fast, and the friction disk heat dispersion is poor, can't effectively discharge the heat that produces timely, causes friction plate to reduce working life.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides a kind of heat dissipation rate fast, the loader copper based powder metallurgy friction wafer that quality of fit is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of loader copper based powder metallurgy friction wafer, comprise the antithesis steel disc, the centre of described antithesis steel disc is a pilot hole, the edge of described pilot hole is cover key tooth, the front and back of described antithesis steel disc is respectively equipped with base copper, the surface of described base copper is provided with broken end groove and spiral chute, is provided with spiral chute between described broken end groove.Broken end groove and spiral chute play good heat radiation and the effect of oil excessively, and cover key tooth can guarantee the interchangeability of friction disk and property slidably.Recessed tooth in the cover key tooth is a circle-arc tooth.
As preferably, described broken end groove comprises broken end groove and 4 outer broken end grooves in 4, described in broken end groove and outer broken end groove be dislocation and be evenly distributed on the base copper surface.
As preferably, the true dip direction of broken end groove equates in described 4, and the true dip direction of described 4 outer broken end grooves equates, described in the end of broken end groove and outer broken end groove be respectively arc end.In broken end groove and outer broken end angle of groove inclination degree be 15 degree.
Therefore, loader copper based powder metallurgy friction wafer of the present utility model, simple in structure, the thermal diffusivity height is convenient to assembling, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sectional structure schematic representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2, a kind of loader copper based powder metallurgy friction wafer, comprise antithesis steel disc 1, the centre of described antithesis steel disc 1 is a pilot hole 2, the edge of described pilot hole 2 is cover key tooth 3, the front and back of described antithesis steel disc 1 is respectively equipped with base copper 4, the surface of described base copper 4 is provided with broken end groove 5 and spiral chute 6,5 of described broken end grooves are provided with spiral chute 6, described broken end groove 5 comprises broken end groove 7 and 4 outer broken end grooves 8 in 4, the groove 7 that breaks end in described is dislocation with outer broken end groove 8 and is evenly distributed on base copper 4 surfaces, the true dip direction of broken end groove 7 equates in described 4, the true dip direction of described 4 outer broken end grooves 8 equates that the end of described interior broken end groove 7 and outer broken end groove 8 is respectively arc end.
