Description
Technical field
The invention belongs to engines distribution structure member technical fields, more particularly, to a kind of engine roller rocking arm.
Background technology
Rocking arm is one of parts important in engine valve actuating mechanism, and function is the movement and effect for transmitting cam
Power changes direction and is transmitted to valve, makes valve opening.Rocking arm shape in valve actuating mechanism is more complicated.Currently, high-power both at home and abroad
The structural shape of diesel engine rocking arm is generally single armed or both arms fork shaped lever, has the characteristics that structure is relatively simple.And it is this
Rocking arm is because both arms forked type is elongate rod, and this rocking arm rigidity is not big enough and both arms forked type bar it is difficult to ensure that rigidity requirement, while
The demand of tight space overhead camshaft arrangement is not adapted to, and valve actuating mechanism frictional work is big；It is past when driving two valves of the same name
There is big phase deviation in opening and closing toward valve, and the error of port timing is larger, can influence the performance of engine.
Invention content
In view of this, the present invention is directed to propose a kind of engine roller rocking arm is, it can be achieved that the high compact Layout top of Four valve
Set the demand of camshaft valve actuating mechanism.And roller rocking arm rigidity is larger, it is ensured that valve opening of the same name is synchronous with closing, has
Accurate port timing.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of engine roller rocking arm, including rocker body, universal ball structure and roller bearing, the rocker body are U
Type structure includes the fork-type arm of interlude and its both ends, and two fork-type arms are by the transition circle segmental arc and straight line coupled with interlude
Section is constituted；The end of two fork-type arms of the rocker body is respectively provided with one and opens a grade bearing hole, each opens a grade bearing hole installation one
Roller bearing is covered, each roller bearing is made of roller and roller axle；The both ends of the interlude of the rocker body are respectively provided with
One mounting hole, each mounting hole install a universal ball structure, and the bottom of the universal ball structure connects pressure head, described universal
Spherical structure is located at upper surface one end installation universal ball end adjustment bolt of interlude；The rocker body is internally provided with oil leab,
The oil duct that lubricating oil is entered back into after being entered in rocker body by the oil circuit on rocker arm shaft on two fork-type arms is lubricating valve rod end
And cam end.
Further, to be equipped with rocking arm oil between the opening on the inside of grade bearing hole of the roller and rocker body stifled.
Further, the oil duct in the fork-type arm is equipped with steel ball in one end of valve.
Further, the interlude is linear type.
Compared with the existing technology, the present invention has the advantage that：
(1) roller rocking arm of the present invention can realize the demand of the high compact Layout air dispensing machine for top-set camshaft of Four valve.And
And roller rocking arm rigidity is larger, it is ensured that valve opening of the same name is synchronous with closing, there is accurate port timing.
(2) between the bearing outer ring and camshaft of roller rocking arm for roll plus sliding, can be effectively reduced rocking arm and
Friction and wear between camshaft, valve actuating mechanism friction power loss reduce, and valve actuating mechanism has good power performance.
(3) the oil leab arrangement of roller rocking arm of the present invention is convenient, and oil can be individually arranged on each arm of both sides
Road can easily realize the lubrication of valve end and each roller bearing；Engine consumption can also be reduced to a certain extent.Rolling
Pillar rocking arm can be applicable on the high reinforcing stimuluses such as engineering machinery, car and boat power, gas engine.
