Abstract
The utility model belongs to rocker arm shaft brackets, and particularly relates to a powder metallurgy rocker arm bracket. The powder metallurgy rocker arm bracket comprises a base, wherein a rocker arm shaft mounting hole is formed in one side of the base; an angle regulation hole is formed beside the rocker arm shaft mounting hole and is perpendicular to the rocker arm shaft mounting hole; an oil cavity is formed in the base; an oil rising ring is arranged on the circumferential wall of the rocker arm shaft mounting hole and communicated with the oil cavity via two or more oil supply passages. The powder metallurgy rocker arm bracket has the advantages that the structure is simple and practical, a rocker arm shaft is fastened only by increasing oil pressure with the oil rising ring, moreover, the matching angle of the base and the rocker arm shaft is regulated via the angle regulation hole; the matching stability and reliability are improved.
Description
Technical field
The utility model belongs to rocker arm shaft support, specifically a kind of powder metallurgy rocker-arm support.
Background technique
Rocker arm shaft support is for supporting engines pitman arm shaft, generally comprises on pedestal, pedestal central axis mutually vertically but do not want pitman arm shaft mounting hole, the adjustment hole handed over, and pitman arm shaft mounting hole, adjustment hole are cylindrical straight hole.Adjustment hole is installed to for adjusting pitman arm shaft the degree of tightness that rocker arm shaft support rear arm axle is installed, and is that the bolt being arranged in adjustment hole by degree of tightness regulates.This mounting type waste material is many, need to repeatedly process, due to the two-way machining hole that exists together, make the strength decreased of bearing, equally due to after installing because the bolt in adjustment hole is fixing dead, cannot unclamp the function that loses adjusting after causing the time permanent, cause the function regulating to perform practically no function.
Summary of the invention
The purpose of this utility model is the deficiency existing for above-mentioned technology, and proposing one does not need to carry out mechanical adjustment degree of tightness, can carry out the powder metallurgy rocker-arm support of angle adjustment simultaneously.
The utility model provides following technological scheme:
Powder metallurgy rocker-arm support, it comprises pedestal, pedestal one side is provided with pitman arm shaft mounting hole; the other angle adjustment holes that is provided with of pitman arm shaft mounting hole; angle adjustment holes is vertical with pitman arm shaft mounting hole; be provided with oil pocket in described pedestal, and pitman arm shaft mounting hole perisporium is provided with the oil ring that rises, and oil rises to encircle and is communicated with by least two oil transportation roads with oil pocket.
In described angle adjustment holes, be provided with nesting level.
The utility model has the advantages that simple and practically, only need to be added oil pressure and just can be realized the fastening of pitman arm shaft by the oil ring that rises, the angle that while pedestal coordinates with pitman arm shaft realizes adjusting by angle adjustment holes; Improve the Stability and dependability coordinating.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, powder metallurgy rocker-arm support, it comprises pedestal 1, and pedestal 1 one sides are provided with pitman arm shaft mounting hole 2, the other angle adjustment holes 3 that is provided with of pitman arm shaft mounting hole 2, angle adjustment holes 3 is vertical with pitman arm shaft mounting hole 2, in described pedestal 1, be provided with oil pocket 4, pitman arm shaft mounting hole 2 perisporiums are provided with the oil ring 5 that rises, and the oil ring that rises 5 is communicated with by least two oil transportation roads 6 with oil pocket 4, be generally to adopt six oil transportation roads 6, in angle adjustment holes 3, be provided with the nesting level 7 for strengthening wear resistance.
Claims (2)
