Description
Technical field
The utility model relates to a kind of friction plate, relates in particular to a kind of low noise marine gearbox copper based powder metallurgy friction wafer, for marine gearbox.
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 be effectively discharge during the heat utmost point that produces, cause friction plate to reduce working life.
Chinese patent 200920207215.5, a kind of friction plate is disclosed, the friction plate that comprises ring-type, be distributed with on two rubbing surfaces of described friction plate on a rubbing surface of fin or described friction plate and be distributed with fin, is distributed with the oil storage pit on another face of this friction plate.The wear resistance of this structure is relatively poor, and working life while is shorter, and maintenance cost is high.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, and a kind of compact structure is provided, and wear resistance is high simultaneously, guarantees the Safety performance of using, and has improved the low noise marine gearbox copper based powder metallurgy friction wafer of friction factor and high-temperature behavior.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of low noise marine gearbox copper based powder metallurgy friction wafer, comprise pairing steel sheet, in described pairing steel sheet, be provided with pilot hole, the edge of described pilot hole is provided with equally distributed assembling tooth, the surface of described pairing steel sheet and the back side are respectively equipped with the copper base fitted with it, and described copper base is provided with equally distributed spiral chute, in spiral chute, are provided with equally distributed radial groove, the diameter of described pilot hole is 244.5mm, and the diameter of described pairing steel sheet is 332mm.
Radial groove and spiral chute play good heat radiation and the effect of oil excessively, and the assembling tooth can guarantee the interchangeability of friction disk and property slidably.
As preferably, the pitch between described spiral chute is 3.0mm, and described spiral fluted groove width is 0.8-1.0mm, and the described spiral fluted degree of depth is 0.5mm; Described radial groove has 12, and the top of described radial groove is connected with the assembling tooth, and the bottom of described radial groove is connected with the outward edge of pairing steel sheet, and the groove width of described radial groove is 5.0-6.0mm, and the groove depth of described radial groove is 0.5mm.
As preferably, described assembling tooth is involute tooth, and the quantity of described assembling tooth is 78.
Therefore, low noise marine gearbox copper based powder metallurgy friction wafer of the present utility model, compact structure, thermal diffusivity is high, and wear resistance is good, high temperature resistant, and matrix strength is high, long service life.
