Description
Technical Field
The utility model relates to a connecting rod plunger structure, concretely relates to connecting rod plunger structure for skewed axis awl fluted pump.
Background
At present, a connecting rod plunger structure mostly adopts a rolling mode to pack a connecting rod and a plunger together. In the process of wrapping the plunger, the plunger is easy to deform and crack due to extrusion of external force, so that the plunger is inflexible to use, has high rejection rate, needs to be replaced in a whole set during maintenance, and has very high maintenance cost. In addition, the connecting rod plunger structure for the bevel gear pump has the advantages that in the long-term operation process, the pressure in the plunger hole cannot be well balanced, and the hole wall cannot be sufficiently lubricated.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims at overcoming the not enough among the prior art, provide a use is nimble, easy dismounting, and the maintenance cost is low, plays balanced oil pressure and lubricated cylinder body effect's balanced oil pressure connecting rod plunger structure for bevel gear pump.
The technical scheme is as follows: in order to solve the technical problem, a balanced oil pressure connecting rod plunger structure for bevel gear pump, it includes connecting rod and plunger be equipped with the plunger hole on the plunger, the plunger hole includes bottom ball socket and draw-in groove be the ball ring groove between bottom ball socket and the draw-in groove be equipped with the ball ring in the ball ring groove be equipped with interior jump ring in the draw-in groove, the bulb of connecting rod is established in bottom ball socket and ball ring plunger outer wall middle part is equipped with the facet of 2-4 equipartitions.
The small plane is a milling groove.
The plurality of facets are provided on the same cross-section of the plunger.
The bottom surface of the small plane is a rectangular plane or a square plane.
And a space is arranged between the ball ring and the ball socket at the bottom.
Has the advantages that: compared with the prior art, the utility model, it is showing the advantage and is: the utility model has the advantages of reasonable overall structure, it includes the plunger, the ball-ring, interior jump ring and connecting rod, all be equipped with the ball socket on plunger hole bottom and ball-ring, the downthehole jump ring groove that is equipped with of plunger, couple together the accessory that has processed with the internal spring can, easy dismounting, it is nimble to use, when maintaining, only need change the accessory of wearing and tearing, need not whole change, greatly reduced the maintenance cost, this structural connection is reliable steady, zero disability rate, be equipped with the facet of 2-4 equipartitions at plunger outer wall middle part, play the effect of balanced oil pressure and lubricated cylinder body, effectively improve whole life and operation effect, accord with the in-service use requirement.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in figure 1, a balanced oil pressure connecting rod plunger structure for skewed axis awl fluted pump, it includes connecting rod 1 and plunger 2 be equipped with the plunger hole on plunger 2, the plunger hole includes bottom ball socket 3 and draw-in groove 4 be ball ring groove 5 between bottom ball socket 3 and the draw-in groove 4 be equipped with ball ring 6 in the ball ring groove 5 be equipped with interior jump ring 7 in the draw-in groove 4, the bulb of connecting rod 1 is established in bottom ball socket 3 and ball ring 6, be equipped with the interval between ball ring 6 and the bottom ball socket 3 2 outer wall middle part of plunger is equipped with the facet 8 of 2-4 equipartitions, facet 8 is the milling flutes, and a plurality of facet 8 are established on the same cross section of plunger 2, facet 8's bottom surface is rectangle plane or square plane. The utility model has the advantages of reasonable overall structure, it includes the plunger, the ball-ring, interior jump ring and connecting rod, all be equipped with the ball socket on plunger hole bottom and ball-ring, the downthehole jump ring groove that is equipped with of plunger, couple together the accessory that has processed with the internal spring can, easy dismounting, it is nimble to use, when maintaining, only need change the accessory of wearing and tearing, need not whole change, greatly reduced the maintenance cost, this structural connection is reliable steady, zero disability rate, be equipped with the facet of 2-4 equipartitions at plunger outer wall middle part, play the effect of balanced oil pressure and lubricated cylinder body, effectively improve whole life and operation effect, accord with the in-service use requirement.
The utility model provides a thinking and method, the method and the way of specifically realizing this technical scheme are many, above only the utility model discloses a preferred embodiment should point out, to the ordinary technical personnel in this technical field, not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improvements should also be regarded as the utility model discloses a protection range, each component that does not make clear and definite in this embodiment all can be realized with prior art.
