Abstract
The utility model discloses the piston pin hole with oil groove on a kind of piston, the periphery that described piston pin hole is formed is axially arranged with at least one oil groove along piston pin hole, the lubricant oil being stored in oil groove can enter piston pin hole with the motion of crank-connecting rod from oil groove, realizes the lubrication between piston pin hole and wrist pin.The utility model structure is simple, reasonable in design, with low cost.
Description
Technical field
The utility model relates to a kind of piston, is specifically related to the piston pin hole with oil groove on a kind of piston.
Background technique
Automobile charged piston, because pressure of explosion increases, makes piston pin hole surface temperature and specific pressure increase, can destroy lubricant film, wrist pin is bitten, therefore need increase the lubrication between piston pin hole and wrist pin surface.
Summary of the invention
The purpose of this utility model is to provide the piston pin hole with oil groove on a kind of piston with significant trapped fuel lubrication.
For achieving the above object, the utility model is by the following technical solutions:
A piston pin hole with oil groove on piston, the periphery that described piston pin hole is formed is axially arranged with at least one oil groove along piston pin hole.
Described oil groove is arc groove.
The width of described oil groove is less than 5mm, and the degree of depth of described oil groove is less than for 0.5mm.
The arc center line of described oil groove and the angle of piston pin hole center line are 20 °.
Described oil groove is 2.
The utility model adopts above technological scheme, along piston pin hole, axially at least one oil groove is set by the periphery formed at piston pin hole, the lubricant oil being stored in oil groove can enter piston pin hole with the motion of crank-connecting rod from oil groove, realizes the lubrication between piston pin hole and wrist pin.The utility model structure is simple, reasonable in design, with low cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail:
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the structural representation of the utility model oil groove.
Embodiment
As shown in the figures 1 and 2, the piston pin hole 1 with oil groove 2 on a kind of piston of the present utility model, the periphery that described piston pin hole 1 is formed is axially arranged with at least one oil groove 2 along piston pin hole 1.
As shown in Figure 2, described oil groove 2 is arc groove, and the width of described oil groove 2 is less than 5mm, and the degree of depth of described oil groove 2 is less than for 0.5mm, the angle that the arc center line of described oil groove 2 and piston pin hole 1 center line are formed is α, α is 20 °.
Described oil groove 2 is 2.
Working principle of the present utility model: along piston pin hole 1, axially at least one oil groove 2 is set by the periphery formed at piston pin hole 1, the lubricant oil being stored in oil groove 2 can enter piston pin hole 1 with the motion of crank-connecting rod from oil groove 2, realizes the lubrication between piston pin hole 1 and wrist pin.
