Description

Adjustment gasket for car engine balance shaft

Technical field

The utility model relates to automobile auxiliary spare part technical fields, are used for automobile engine in particular to one kind The adjustment gasket of balance shaft.

Background technique

It is inevitable since piston does the movement of high-speed straight-line repeatedly in cylinder in the automobile engine course of work Biggish inertia force can be generated on piston, piston pin and connecting rod, and then lead to entire engine causes vibration.Positioned at engine Interior balance shaft is the vibration for balancing and reducing engine, and realizing reduces engine noise, prolong the service life, promoted and driven The purpose of the person's of multiplying comfort；And it is located at the installation gap that the adjustment gasket in balance shaft is then used to adjust itself and supported hole, and with Rotate together.

But due to being limited by engine structure, the lubricating oil in engine cavity is difficult to enter into balance shaft and supported hole Between gap, therefore the lubricant effect between balance shaft and supported hole is relatively poor, is easy to produce abrasion, will lead to balance shaft Counterbalance effect is deteriorated, and entire engine luggine increases, service life reduction.

Utility model content

The purpose of this utility model is to provide a kind of adjustment gaskets for car engine balance shaft, are improved with this flat The greasy property of weighing apparatus axis, reduces the vibration of engine, increases service life topic.

To realize the utility model aim, the technical solution used for：For the adjustment gasket of car engine balance shaft, Including shim body；Multiple oil grooves are offered at least one end face in two end faces of the shim body, multiple oil grooves are equal Radial direction along shim body is arranged, and multiple oil grooves on each end face are along the circumferencial direction uniform intervals of shim body Arrangement；The periphery of shim body is run through in one end of each oil groove, and the other end of each oil groove runs through the inner headed face of shim body On.

Further, the section of the oil groove be triangle, rectangle, it is trapezoidal in one of which.

Further, the oil groove is extrusion process molding.

Further, the opening width of the oil groove is 0.5 ~ 3mm.

Further, the depth of the oil groove is less than the half of shim body thickness.

Further, the section of the oil groove is arc-shaped, a diameter of 0.5mm ~ 3mm.

The utility model has the beneficial effects that

1. not only making the counterbalance effect of gasket more preferably under the premise of not influencing gasket and balance shaft working performance；And it mentions High greasy property between balance shaft and said spacer mounting bores, prevents from or reduces balance shaft wearing.

2. effectively mitigating gasket weight, and then mitigate entire engine weight, reduces oil consumption；And itself and balance shaft can be increased Frictional force between end face can be rotated preferably with balance shaft simultaneously, to reduce the abrasion of relative motion generation.

Detailed description of the invention

Specific embodiment

The utility model is further described in detail below through specific implementation examples and in conjunction with the accompanying drawings.

A kind of adjustment gasket for car engine balance shaft provided by the utility model shown by Fig. 1, Fig. 2, packet Include shim body 1；Multiple oil grooves 2, multiple oil grooves 2 are offered in two end faces of the shim body 1 at least one end face It is arranged along the radial direction of shim body 1, and circumferencial direction of the multiple oil grooves 2 along shim body 1 on each end face is equal It is even to be intervally arranged；The periphery of shim body 1 is run through in one end of each oil groove 2, and the other end of oil groove 2 is through shim body 1 On inner headed face.

The shim body 1 is annular shape, and two end faces of shim body 1 are the front and back sides of gasket；The pad The oil groove 2 on one of end face in two end faces of piece ontology 1 is at least 2, and in two end faces of shim body 1 Oil groove 2 on another end face is more than or equal to 0, and 2 sum of oil groove on two end faces is axially equal along the circumference of shim body 1 It is even to be intervally arranged, to keep the distribution of weight of shim body 1 uniform, make shim body 1 when rotating synchronously with balance shaft, gasket Ontology 1 is able to maintain balance.By the way that oil groove 2 is arranged to through slot structure, the lubricating oil in oil groove 2 can be effectively set smoothly to be flowed into Between balance shaft and said spacer mounting bores, keep the greasy property between balance shaft and said spacer mounting bores more preferable, prevents or reduce balance Axis is worn.

The section of the oil groove 2 be sector, triangle, rectangle, it is trapezoidal in one of which, the concrete shape of oil groove 2 can It is adjusted according to the thickness of gasket or actual use situation.The oil groove 2 is extrusion process molding, makes adding for oil groove 2 Work is more quick and convenient, so that the processing efficiency of gasket be made to greatly improve.The opening width of the oil groove 2 is 0.5 ~ 3mm, and oily The depth of slot 2 is less than the half of 1 thickness of shim body.The section of the oil groove 2 is arc-shaped, when the section of oil groove 2 is arc When shape, the diameter of oil groove 2 is 0.5mm ~ 3mm.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
