Abstract
The utility model discloses a dry-type iron-base main clutch friction disk, which is constituted by an outer ring type ring-shaped steel core board and dry-type iron-base powder metallurgy friction material, wherein the powder metallurgy friction material is sintered on the two sides of the steel core board. The outer circle of the steel core board is provided with 123 gears, the double faces are sintered with 16 sheets of fan-shaped tablet pressed compacts which are pressed by dry-type iron-base powder metallurgy friction material and 8 sheets of single faces, and certain distance gap exists between each fan-shaped tablet pressed compact. The utility model eliminates the phenomenon of sintering and carbon penetration of the iron-base friction disk steel core board, greatly reduces brittleness of the friction disk, puts an end to fracture accidents of the friction disk, and enhances the friction performance of the friction disk by improving size preciseness, and the working of the clutch is more stable and reliable.
Description
Technical field
The utility model patent relates to a kind of friction plate, relates in particular to a kind of dry type iron-based Main Clutch Friction Plate.
Background technique
GJW320 type crawler trench excavator is large-scale crawler that I engineer of army the fills the domestic gaps working equipment of digging pit, because this car is efficient, quick type earthwork machine, its clutch is frequent operation under abominable geological condition, and is therefore high to the performance requirement of friction plate.GJW320 type crawler trench excavator main clutch has adopted the dry type ferrous based powder metallurgical friction plate of seldom using at present both at home and abroad.Iron-based friction material generally is applied to the thicker one sintered friction plate of steel core board size or is used to rivet the combined type friction plate, is used in the break more.And, generally all adopt the wet type copper base friction plate for engineering machinery and tank, armored vehicle clutch friction plate, with defectives such as the steel backing brittle failure avoiding causing and sintering warpages because of carburizing.
So far, in the military, civilian at home machinery of dry type iron base friction plate multidisc clutch, the precedent of application is arranged seldom, domestic other enterprises of the key technology problems in its friction plate manufacturing and R﹠D institution still are difficult to resolve and determine.
Summary of the invention
The purpose of this utility model provides a kind of dry type iron-based Main Clutch Friction Plate.
The technological scheme that the utility model technical solution problem is adopted is:
Adopt external tooth type ring-type steel core plate and dry type iron-based powder metallurgy friction material sintering to form, wherein the powder metallurgy friction material sintering is in steel core plate both sides.
Described steel core plate is the external tooth type ring structure, and cylindrical has 123 teeth.
Described powder metallurgy friction material is the dry type iron-based powder metallurgy friction material, forms the fanning strip pressed compact by compacting, pieces together circle and is sintered in steel core plate both sides.
16 dry type iron-based powder metallurgy friction materials of the two-sided sintering of the steel core plate of described friction plate fanning strip pressed compact, 8 of single faces.
The beneficial effects of the utility model are: employing dry type iron-base powder metallurgy material is sintered in the method for external tooth type ring-type steel core plate both sides, has strengthened the frictional behaviour of friction plate, has improved dimensional accuracy.Eliminate iron base friction plate steel core plate sintering carburizing phenomenon, greatly reduced friction plate fragility, stopped the fracture accident of friction plate.By improving dimensional accuracy, clutch stable working and reliability have been strengthened.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further, but not as to qualification of the present utility model.
As shown in Figure 1 and Figure 2, dry type iron-based Main Clutch Friction Plate forms 8 of single faces by 16 two-sided sintering of dry type iron-based powder metallurgy friction material fanning strip pressed compact in a slice steel core plate both sides.
As shown in Figure 3, the steel core plate before the sintering is the external tooth type ring structure, and cylindrical has 123 teeth.
As shown in Figure 4, the dry type iron-based powder metallurgy friction material is the fan shape small pieces.
Manufacture method is: adopting steel core plate, dry type iron-based powder metallurgy friction material is raw material, produces Main Clutch Friction Plate by compacting, sintering and machining.
Specific embodiment of the present utility model elaborates content of the present utility model.For persons skilled in the art, any conspicuous change of under the prerequisite that does not deviate from the utility model spirit it being done all constitutes the infringement to the utility model patent, with corresponding legal responsibilities.
