Abstract
The utility model relates to a friction plate, in particular to a paper-based friction plate used for a large-sized tractor. The paper-based friction plate comprises dual steel plates. A mounting hole is arranged in the middle of each of the dual steel plates, key sleeving teeth are arranged at the edge of each of the mounting holes, the front surface and the back surface of each of the dual steel plates are respectively provided with a paper-based layer, a waffle slot is arranged on the surface of each of the paper-based layers, an oil guide hole is arranged between each of the paper-based layers and each of the mounting holes, the slot width of the waffle slots is 2mm, and the slot pitch of the waffle slots is 19mm. The paper-based friction plate used for the large-sized tractor is simple in structure, high in radiating performance, convenient in assembly and long in service life.
Description
Technical field
The utility model patent relates to a kind of friction plate, relates in particular to a kind of paper-base friction wafer that is used for large tractor.
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 paper-base friction wafer that is used for large tractor 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 paper-base friction wafer that is used for large tractor, 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 surface and the back side of described antithesis steel disc are respectively equipped with paper substrate, and the surface of described paper substrate is provided with magnificent husband's groove, is provided with oil guiding hole between described paper substrate and pilot hole, the groove width of described magnificent husband's groove is 2mm, and the slot pitch of described magnificent husband's groove is 19mm.
China husband groove plays good heat radiation and the effect of oil excessively.
As preferably, the diameter of described oil guiding hole is 6mm, and the knuckle in described magnificent husband's groove is a chamfering, and described oil guiding hole has 6,6 oil guiding holes be evenly distributed in pilot hole around.
As preferably, the thickness of described antithesis steel disc is 13mm, and the thickness of described paper substrate is 1mm.
Therefore, the paper-base friction wafer that is used for large tractor of the present utility model, simple in structure, the thermal diffusivity height is convenient to assembling, long service life.
