Abstract
The utility model provides an oil ring which comprises a ring body. The inner wall face of the ring body is provided with a circle of first groove in a concave mode, the outer wall face of the ring body is provided with a circle of second groove in a concave mode, a plurality of through holes are arranged between the first groove and the second groove, and the plurality of through holes enable the first groove and the second groove to be communicated. Due to the structure that the through holes which are distributed evenly at intervals inside the oil ring, and the through holes enable the first groove and the second groove which are respectively arranged on the inner wall face and the outer wall face of the oil ring in a concave mode to be communicated, the weight of the oil ring is effectively lowered, and the sealing performance and the lubricating effect of the oil ring are improved.
Description
Technical field
The utility model relates to a kind of lubricating fitting, relates in particular to a kind of oil ring.
Background technique
As everyone knows, gear-box is a kind of device of transferring power or adjusting rotary speed.Its inside generally includes the gear of the some groups of starts that cooperatively interact.The problem that gear-box often occurs mainly comprises: damage of bearings, gear destruction, off-axis, seepage wet goods.So in order to improve the working life of gear-box, how to improve the part of gear-box accomplished to lubricate comprehensively and effectively, become one of the MANUFACTURER of gear-box or research direction of user.
Oil ring is as the constituent element of lubricating fitting in the gear-box, and it plays an important role to the lubricated of gear-box.It is large that oil ring of the prior art exists quality of product, and friction factor is large, the defective that adaptation and lubrication effect are undesirable.
In view of this, be necessary oil ring of the prior art is improved, to address the above problem.
The model utility content
The purpose of this utility model is to provide a kind of oil ring, in order to alleviate the quality of oil ring, improves sealing and the lubrication effect of oil ring.
For realizing above-mentioned model utility purpose, the utility model provides a kind of oil ring, comprise ring body, the internal face of described ring body is arranged with a circle the first groove, the outer wall of described ring body is arranged with a circle the second groove, be provided with some through holes between described the first groove and the second groove, described through hole connects described the first groove and the second groove.
As further improvement of the utility model, the even compartment of terrain of described through hole is arranged in the described ring body.
As further improvement of the utility model, the cross section of described through hole is circular.
As further improvement of the utility model, the quantity of described through hole is seven.
As further improvement of the utility model, the side ring surface of any side of described ring body is provided with a conical surface.
As further improvement of the utility model, the tapering of described conical surface is 10:1.
As further improvement of the utility model, the sectional shape that described the first groove is arranged with into the internal face of described ring body is semicircle.
As further improvement of the utility model, the sectional shape that described the second groove is arranged with into the outer wall of described ring body is semicircle.
Compared with prior art, the beneficial effects of the utility model are: by the through hole that evenly is intervally arranged is set in oil ring, this through hole connects the first groove and the second groove that the inside and outside wall of oil ring is arranged with, by this structure, the quality that it has alleviated oil ring has effectively improved sealing and the lubrication effect of oil ring.
Description of drawings
Fig. 1 is the front view in a kind of oil ring one embodiment of the utility model;
Fig. 2 is the sectional view along A-A line among Fig. 1.
Embodiment
Below in conjunction with each mode of execution shown in the drawings the utility model is elaborated; but should be noted that; these mode of executions are not limitation of the utility model; those of ordinary skills all belong within the protection domain of the present utility model according to these mode of execution institute work energy, method or structural equivalent transformation or alternative.
Shown in please refer to the drawing 1, wherein Fig. 1 is the front view in a kind of oil ring one embodiment of the utility model.In the present embodiment, a kind of oil ring 10, it comprises ring body 1, and the internal face 11 of this ring body 1 is arranged with a circle the first groove 111, and the outer wall 12 of this ring body 1 is arranged with a circle the second groove 121.Be provided with some through holes 14 between this first groove 111 and the second groove 121, described through hole 14 connects described the first groove 111 and the second groove 121.
In the present embodiment, this oil ring 10 can be arranged on the gear main shaft in the gear-box (not shown), lubricant oil in the gear-box can be by arranging on this oil ring 10 through hole 14 provide lubricant oil to main shaft, thereby reduced the frictional force between gear and the main shaft, and effectively the part of gear-box inside is lubricated, improve the working life of gear-box, reduced the maintenance of operating personnel to gear-box.
In conjunction with shown in Figure 2, in the present embodiment, these through hole 14 even compartment of terrains are arranged in the ring body 1.Wherein, the cross section of this through hole 14 is circular, and the quantity of set through hole 14 is seven in this oil ring 10.The sectional shape that this first groove 111 is arranged with into the internal face 11 of this ring body 1 is semicircle.The sectional shape that this second groove 121 is arranged with into the outer wall 12 of this ring body 1 is semicircle.
More specifically, the side ring surface 13 of this ring body 1 any side is provided with a conical surface 131, and the tapering of this conical surface 131 is 10:1.This conical surface 131 can with gear-box in seal ring (not shown) effectively fit, thereby improved the sealing of this oil ring 10.
