Summary of the invention
The whole barrel-shaped tappet device of a kind of pressure lubrication of the present invention, technical problem to be solved is to improve Injection Pump pressure lubrication, refrigerating function and bearing capacity, may be used in pump in upright arrangement, monoblock pump, the co-rail fuel feed pump.
For solving the problems of the technologies described above, the scheme that the present invention adopts is:
The whole barrel-shaped tappet device of a kind of pressure lubrication; Mainly comprise stop sleeve 1, feather key 2, tappet body 3, roller pin 4, roller 5; It is characterized in that tappet body 3 is provided with 2 through holes 8, roller pin hole 9, roller pin hole 10 and guiding groove 11, roller 5 is sleeved on the roller pin 4; Be installed between the roller pin hole 9 and roller pin hole 10 of tappet body 3; Tappet body 3, roller pin 4, roller 5 are assembled into one, are assemblied in the stop sleeve 1, rely on feather key 2 in tappet body wall face guiding groove 11, to lead with spacing.
Above-mentioned rollers pin 4 adopts interference fit with tappet body 3, and magnitude of interference is 0.01～0.039mm, and roller 5 is a Spielpassung with roller pin 4, and the gap is 0.071～0.122mm, and tappet body 3 is a Spielpassung with stop sleeve 1, and the gap is 0.025～0.089mm.
2 vertical oil grooves 6 of above-mentioned stop sleeve 1 cylindrical wall design, oil groove is of a size of R0.3, and length to stop sleeve 1 bottom edge at 2 vertical oil groove 6 ingress design cross through hole 7, is of a size of Φ 6mm.
Above-mentioned rollers 5 materials adopt Rapid Tool Steel W6Mo5Cr4V2, and roller pin 4 materials adopt beryllium bronze QBe2.
The whole barrel-shaped tappet device of a kind of pressure lubrication of the present invention compared with prior art has following beneficial effect:
1, realizes the pressure lubrication of tappet parts and camshaft; In diesel engine or all running operating mode processes of Injection Pump; Lubricant oil all has definite flow direction and flow; Not only between tappet and stop sleeve, form the pressure lubrication oil film, and direct directive roller of lubricant oil and cam, lubricated and cooling effect is superior to the splash lubrication of conventional tappet parts.
2, the tappet body adopts whole barrel shaped structure, and cylindrical guiding length is big, and deformation is little, is easy to form the pressure lubrication oil film, improves bearing capacity.
3, in the tappet body, be designed with 2 through holes; Reduce the pump-absorb action of tappet parts in movement process on the one hand; In tappet to-and-fro motion process, can form the lubricant oil jet on the other hand, further cooling and lubricating roller and cam, the fatigue that improves roller and cam contacts the life-span.
4, cancellation roller bush, the rigidity of enhancing roller pin and roller improves bearing capacity, and reduces number of spare parts, reduces cost.
5, roller pin, roller material are mated rationally, and wear-resisting property is good.
