Friction plate assembly performance traditional at present is poor, and assembly precision is not high, while coefficient of friction is low, and product loss is fast, rubs
It is poor to wipe disk heat dispersion, the reduction of friction plate service life can not be caused effectively discharge during caused heat pole.
Chinese patent 201320313869.2, a kind of low noise marine gearbox copper based powder metallurgy friction wafer is disclosed, wrapped
Pairing steel sheet is included, pilot hole is provided with described pairing steel sheet, the edge of described pilot hole is provided with equally distributed assembling tooth,
The surface and the back side of described pairing steel sheet are respectively equipped with the copper base to fit therewith, and described copper base, which is provided with, uniformly to be divided
The helicla flute of cloth, equally distributed radial slot, a diameter of 244.5mm of described pilot hole, institute are provided with described helicla flute
The a diameter of 332mm for the pairing steel sheet stated.The performance of this structure is relatively low.
The content of the invention
The utility model mainly solves the deficiencies in the prior art, there is provided one kind can quickly be radiated, more
Protection equipment normal operation the special friction plate of large-tonnage ships gear-box.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of special friction plate of large-tonnage ships gear-box, including core plate, the centre of described core plate are provided with pilot hole, institute
The a diameter of 308mm for the pilot hole stated, the edge of described pilot hole are provided with the assembling tooth of uniformly continuous distribution, described assembling
The number of teeth of tooth is 45, and surface and the back side of described core plate are respectively equipped with copper-based liner, and the surface of described copper-based liner is set
There is continuously distributed helicla flute, 6 radial slots divided equally are provided with described helicla flute, the groove width of described helicla flute is 0.9
~1mm, the pitch between adjacent grooves are 4mm, and the groove width of described radial slot is 6mm, described radial slot and helicla flute
Depth is respectively 0.5~0.6mm；
The depth ecto-entad of described radial slot is gradually deepened, the outer end of described radial slot and copper-based liner outward flange
Spacing be 5.5mm.
Preferably, the thickness of described core plate is 10.5mm, the gross thickness of two copper-based liners and core plate is 12mm, institute
The pilot hole stated and radial slot overall diameter are 458mm.
Preferably, the bottom land of described radial slot is distributed in arcuation.
Preferably, the outer knuckle of described copper-based liner is in the distribution of falling shape.
This structure can significantly lift the performance of product.
Therefore, the special friction plate of large-tonnage ships gear-box of the present utility model, heat radiation is high, is easy to assemble, and protects
Protect equipment normal operation, service life length.
