Description
Technical field
The present invention relates to engine rocker, especially a kind of rocking arm with oil storage tank.
Background technology
With developing rapidly for auto industry, people propose higher and higher to dynamic property, the economy of automobile engine
It is required that, promote automobile engine to develop to high intensity, high speed, low oil consumption, low emission, high life direction, so that also to parts
Product proposes requirements at the higher level.Valve rocker improves its wearability, reduction friction system as one of automobile engine vital part
Number, lightweight, raising life-span etc. are the targets that valve rocker design is pursued with manufacture.
General valve rocker is made up of two parts, and main body is rocker body, and another part is needle bearing；Needle bearing is by three
Part is constituted, respectively roller, bearing pin and needle roller, and the needle roller and roller of bearing are supported by bearing pin, and the bearing pin of bearing and rocking arm
Body is riveted together, and is that the typical case of this rocking arm constitutes structure.
Needle bearing and cam contact, with cam rotation and pass to valve with this to drop during work by power by rocking arm
Low-friction coefficient, improves service life, but the bearing pin of this rocker bearing is riveted together with rocking arm, above covered with needle roller and
Roller, due to the gap very little between roller and rocker body, therefore causes bearing pin, roller in work in lubricating oil bearing more difficult to get access
There is dry friction phenomenon with needle roller, easily cause bearing pin or needle roller inordinate wear situation occurs, this is also to cause the rocking arm life-span not
One of dominant failure factor of foot.
The content of the invention
The purpose of the present invention, aiming at the deficiency present in prior art, and provides a kind of rocking arm with oil storage tank,
The program increases axial gap with needle roller, lubricating oil just can be from this gap using setting oil storage tank on the inside of rocker body with this
In give bearing to provide certain more lubrication, reach the purposes for improving bearing service life.
This programme is achieved by the following technical measures：
A kind of rocking arm with oil storage tank, includes rocker body and the needle bearing being fixed in rocker body, the inner side of rocker body
Face, which is located on the region of needle bearing correspondence position, is provided with oil storage tank.
It is used as the preferred of this programme：The spacing H of oil storage tank and the spacing h of rocking arm inwall relation is：H/h=1.1-1.3.
It is used as the preferred of this programme：Needle bearing includes bearing pin, needle roller and roller；Needle bush is on bearing pin；Roller housing
On needle roller.
It is used as the preferred of this programme：Rocker body, which is located on the madial wall above oil storage tank, is provided with inclined-plane.
It is used as the preferred of this programme：The radius of oil storage tank is R, and the internal diameter of roller is r, and the external diameter of roller is M, and M>R>r.
It is used as the preferred of this programme：The width of needle roller is L1, and the width of roller is L2, and L1<L2.
It is used as the preferred of this programme：Bearing pin can rotate relative to rocker body.
It is used as the preferred of this programme：Roller includes body and stage portion；Stage portion is arranged on the outside of roller；Stage portion
Width be L3, the width of body is L2, and L3<L2.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due to being set in this scenario on the inside of rocking arm
Oil storage tank is put, lubricating oil can be easy to remain in oil storage tank, the lubricant effect persistently to needle bearing is played；Between oil storage tank
Relation away from H and the spacing h of rocking arm inwall is：H/h=1.1-1.3, this setting can either ensure that spacing width is suitable, again can
Ensure that the roller scope of activities of needle bearing will not be excessive；It is provided with using being located in rocker body on the madial wall above oil storage tank
Inclined-plane, can be easy to lubricating oil to flow into oil storage tank；The radius R of oil storage tank and the internal diameter of roller are r, external diameter the setting for M of roller
Relation is put, the needle roller and roller portion of lubricating oil effectively lubricating needle bearing is ensure that；The width of needle roller is used for L1, roller
Width be L2 and L1<L2 setting, can reduce the weight of needle bearing, while can also be internally formed certain sky in roller
Between oil storage, it is ensured that needle roller and roller good lubrication effect；Body and stage portion are included using roller；Stage portion is set
On the outside of roller；The width of stage portion is L3, and the width of body is L2 and L3<L2 set-up mode, can mitigate roller weight
Amount, while forming oil storage space outside roller, adds the amount of storage of lubricating oil, further ensures the profit of roller and needle roller
Sliding effect；The set-up mode that bearing pin can be rotated relative to rocker body is to make bearing pin and rocker body rolling friction, reduces and rub
Resistance, improves the response speed and flexibility ratio of rocking arm.
As can be seen here, the present invention compared with prior art, with substantive distinguishing features and progress, its beneficial effect implemented
It is obvious.
