Abstract

The utility model provides a rocker arm liner bushing, and belongs to the technical field of mechanical projects. The rocker arm liner bushing solves the problems that existing valve rocker arm usingprocess has bad stability, trivial installation and detachment, and the like. The rocker arm liner bushing comprises a body which is in a cylinder shape and made of metal materials. The body is an integral structure, the lateral part of the body is provided with a penetrated gap, and two ends of the body gap are provided with embedding structures which can be used to fixedly connect the two ends.The rocker arm liner bushing has the advantages of simple structure, long service life, excellent stability in the using process, convenient installation and detachment, and the like.

Description

Rocker arm bush

Technical field

The utility model belongs to mechanical engineering technical field, relates to a kind of lining, particularly a kind of rocker arm bush.

Background technique

Rocker arm bush is heavy-duty engine indispensable vitals in the rocker arm body; in the process of the rocking arm and the relative movement of axle, play the protection parts usually; prevent that friction owing to long-term from causing the loss of parts; reduce the wearing and tearing between part and the part, prolonged the working life of part.At present, the inside and outside in the course of the work two sides of lining respectively contacts different parts, so existing rocker arm bush is generally double layer construction and double-deck material also has nothing in common with each other, and this rocker arm bush also suitable trouble of manufacturing price costliness but also manufacture process not only, complex structure, the design unreasonable, this type of rocker arm bush is owing to made by double layer material, the coherent material damage that comes off easily in long-term high-frequency working procedure.

Summary of the invention

The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the rocker arm bush of a kind of integral structure, long service life.

The purpose of this utility model can realize by following technical proposal: a kind of rocker arm bush, comprise body cylindric and that make by metallic material, it is characterized in that, described body is an integral structure, described body sidepiece has the breach that runs through, and the two ends of described body indentation, there have the embedding junction structure that it can be connected.

Body is that the rocker arm bush of integral structure makes things convenient for impact briquetting, by interference fit lining is pressed into rocking arm inner hole.In the process of using, rocker arm bush is inboard to contact and relative in the course of the work slip with pitman arm shaft, can guarantee that not only rocking arm works normally, and passes through heat treated rocker arm bush inboard and also reduced pitman arm shaft frictional loss in the course of the work.

In above-mentioned rocker arm bush, described embedding junction structure is the plush copper at body one end place and the recess at body the other end place.Concavo-convex embedding knot mode is easy for installation and removal, and press-fits back Cheng Yuan automatically, has also simplified the working process of whole lining.

As another scheme, in above-mentioned rocker arm bush, described embedding junction structure is the recess at body one end place and the plush copper at body the other end place.

In above-mentioned rocker arm bush, the quantity of described plush copper and recess is 2-5.The quantity of plush copper and recess embedding knot has determined the soundness of the use of whole lining, can formulate the quantity of embedding knot according to the needs of the intensity of working.

In above-mentioned rocker arm bush, described plush copper and recess and body are integral structure.Integral structure has been realized the simple and firm of whole lining.

In above-mentioned rocker arm bush, described body is made by steel plate materials.Practical and convenient by the body that steel plate materials is made to its processing.

Compared with prior art, the utility model has following advantage; 1, because the body two ends of being made by steel plate materials have the embedding junction structure that it can be connected, so the lining rigidity is better, the using process good stability.2, the embedding junction structure is easy for installation and removal by the cooperation embedding knot of plush copper and recess.

Description of drawings

Fig. 1 is the structural representation of rocker arm bush.

Among the figure, 1, body; 2, embedding junction structure; 11, plush copper; 12, recess.

Embodiment

Embodiment 1:

As shown in Figure 1, this rocker arm bush comprises body 1 cylindric and that made by metallic material, integral structure body 1 sidepiece has the breach that runs through, the two ends of indentation, there have the embedding junction structure 2 that it can be connected, described embedding junction structure 2 is by the plush copper 11 at body 1 one end places and the recess 12 at body 1 the other end place, and quantity is that 2-5 plush copper 11 and recess 12 is integral structure with body 1.

Body 1 be the rocker arm bush of integral structure by impact briquetting, by the mutual embedding knot between plush copper 11 in the embedding junction structure 2 at two ends and the recess 12 it is fixed into cylindricly, inside and outside two sides realizes that by handling there is different performances inside and outside both sides.In the process of using, rocker arm bush inboard with pitman arm shaft contact and relative in the course of the work slip, can guarantee that not only rocking arm works normally, and the heat treated rocker arm bush of process inboard has also reduced and pitman arm shaft between friction.

Embodiment 2:

In above-mentioned rocker arm bush, the embedding junction structure is recessed 12 and the tang 11 at body the other end place at body 1 one end places.

All the other structures of present embodiment all with embodiment 1 roughly the same, this paper does not do and gives unnecessary details.

Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.

Although this paper has used 1, body morely; 2, embedding junction structure; 11, plush copper; 12, recess.Deng term, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
