Description
Technical field
Plunger tappet parts are the utility model is related to, especially a kind of tappet.
Background technology
Tappet is the chief component of automobile fitting mechanism, is to utilize engine oil pressure by the power transmission on camshaft on eccentric wheel
Mechanism to valve.And existing tappet and cam junction be because collision or other factors are also easy to produce deviations, i.e., cam is with enduring
Bar contact position departs from, and connection loosely causes work smooth can not complete, therefore potential safety hazard be present.
Utility model content
For the deficiency in background technology, the utility model provides a kind of tappet, and overcomes disadvantages described above.
Technical scheme is used by the utility model solves its technical problem：A kind of tappet, including the first connection end,
Two connection ends and the main body of connection the first connection end of connection and second connection end, first connection end is bulge-structure, and is held
Portion is provided with groove, and the bottom of the groove is provided with the recessed spherical groove put, and ball built in groove, the both sides of the inwall of the groove are provided with
Space, is provided with hole between the space and groove, the only ball with elastic component in the space, and ball passes through hole portion
It is point exposed outside；The second connection end is set for protrusion spherical structure, and the spherical structure diameter is more than main diameter.
Volume of the groove not less than half of ball.
Described ball one end positioned at groove both sides connects elastic component, other end overhead in hole, the elastic component it is another
End is fixed in space, is connected between the ball and elastic component by retainer ring.
The diameter in the hole is less than ball diameter disposed within.
First connection end, second connection end and the main body are integral type structure setting.
Connected loosely by adopting the above-described technical solution, effectively improving junction between existing tappet and cam
The problem of, the tappet is reasonable in design simple, is engaged by groove with cam, it is ensured that tappet does not depart from convex in the course of work
Wheel, with ball is provided with time slot, makes the connection between tappet and cam more flexible.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 partial enlargement structural representation.
1, first connection end in figure；2nd, second connection end；3rd, main body；4th, groove；5th, groove；6th, ball；7th, space；8th, hole；
9th, retainer ring；10th, cam；11st, elastic component.
Embodiment
Fig. 2 is combined with reference to figure 1 to understand, the utility model：A kind of tappet, including the first connection end 1, second connection end 2 and
Connection the first connection end 1 of connection and the main body 3 of second connection end 2, the main body 3 are set for cylindrical structural, and described first connects
It is bulge-structure to connect end 1, and end is provided with groove 4, and the bottom of the groove 4 is provided with the recessed spherical groove 5 put, ball built in groove 5
6, the both sides of the inwall of the groove 5 are provided with space 7, and hole 8 is provided between the space 7 and groove 5, is only had in the space 7
Ball 6 with elastic component 11, and ball 6 through the partial denudation of hole 8 outside；The second connection end 2 is protrusion sphere knot
Structure is set, and the spherical structure diameter is more than the diameter of main body 3.
The groove 5 ensures ball 6 without departing from out groove 5 not less than the volume of half of ball.
Described to connect elastic component 11 positioned at one end of ball 6 of the both sides of groove 4, other end overhead is in hole 8, the elastic component 11
The other end be fixed in space 7, connected between the ball 6 and elastic component 11 by retainer ring 9, specifically, the fixation
Ring 9 is fixed on elastic component 11, and ball 6 is placed in retainer ring 9, and retainer ring 9 and the face of the contact surface of ball 6 and ball 6 are adapted,
It is concaveconvex structure on its contact surface, the bump height of concaveconvex structure unanimously forms the cambered surface being adapted with the surface of ball 6, convex
Point structure setting reduces the contact area between retainer ring 9 and ball 6, so as to reduce friction, makes the using flexible of ball 6, ball 6
To be fixed by the power between retainer ring 9 and hole 8, both sides are provided with the cam 10 that ball 6 makes the first connection end 1 be applied to different-thickness,
It is applied widely.
The diameter in the hole 8 is less than the diameter of ball 6 disposed within, the retainer ring 9 it is interior through being less than in the inner
The diameter of ball 6.
First connection end 1, second connection end 2 and main body 3 are integral type structure setting.
Its course of work is that the checkpost of cam 10 is put built in the groove 4 in the first connection end 1, the edge overhead of cam 10 with
It is located at ball 6 in groove 5 to offset, two sides of cam 10 are in contact with the ball 6 provided with elastic component 11, and ball 6 can be with convex
Wheel 10 is rotated and rotated；The cambered surface that the protrusion spherical structure of the second connection end 2 is placed in one end of the rocking arm of control valve is recessed
In groove, structure is connected firmly flexibly.By setting ball 6 to improve using flexible degree.
The utility model effectively improves the problem of junction is connected loosely between existing tappet and cam, the tappet
It is reasonable in design simple, it is engaged by groove with cam, it is ensured that tappet does not depart from cam in the course of work, with being provided with time slot
Ball, make the connection between tappet and cam more flexible.
Every technical staff's notice：Although the utility model describes according to above-mentioned embodiment, this
The invention thought of utility model is not limited to that utility model, any repacking with inventive concept, will all include this specially
In sharp scope of patent protection.
