Abstract
The utility model discloses an oily bearing, which comprises a bearing main body, a sealing ring, a snap ring, a pad and a seal cover, wherein the bearing main body is provided with through hole, and one end of the bearing main body is provided with an annular convex part. One side of the sealing ring is provided with a locking groove, and the locking groove is communicated with a hole of the sealing ring. The sealing ring is sleeved on the end part of the bearing main body, and the annular convex part is plugged inside the locking groove. The snap ring, the pad and the seal cover are superposed onto the other end of the bearing main body. The sealing ring is sleeved on end part of the bearing main body, and the annular convex part is plugged inside the locking groove, so the sealability is better, and the leakage of lubricating oil can be adequately prevented.
Description
Technical field
The utility model relates to a kind of bearing means, especially relates to a kind of oil-impregnated bearing.
Background technique
Bearing is the parts that are used for supporting rotations such as helper motor rotating shaft, does not have the auxiliary of bearing, then because frictional force is big motor can't be rotated, thereby bearing has very important effect at the device by electric-motor-driving.Common ball bearing comprises bearing housing, lining, ball and axle center, the form of coaxial setting inside and outside described lining is with described bearing housing, be provided with described plurality of balls between described lining and the described bearing housing, described axle center is positioned at described lining, and can rotate with respect to bearing housing, ball increases the lubricity of ball and ball bearing by butter.
Along with the prolongation of service time, the high temperature that long-time use is caused changes butter oil, thereby makes the noise that oiling agent reduces and generation is bigger around the ball, in addition, and described ball bearing cost height.For addressing the above problem, oil-impregnated bearing arises at the historic moment, and the relative ball bearing price of oil-impregnated bearing is lower, and it is mainly made by materials such as alloys such as iron, copper or stainless steels, can use for a long time, thereby is subjected to using widely.Yet existing oil-impregnated bearing sealing is poor, occurs the problem of leakage of oil usually.
Summary of the invention
The utility model is the oil-impregnated bearing that a kind of good airproof performance is provided at the defective that the above-mentioned background technology exists.
For achieving the above object, the utility model discloses a kind of oil-impregnated bearing, it comprises bearing body, seal ring, snap ring, liner and sealing cover, and described bearing body is provided with perforation, and an end of described bearing body is provided with annular protrusion.One side of described seal ring is provided with snap groove, and this snap groove is connected with the circle hole of seal ring.Described seal ring is set on the end of described bearing body, and described annular protrusion is plugged in the described snap groove.Described snap ring, liner and sealing cover are stacked in the other end of described bearing body mutually.
Further, one end of described bearing body is provided with accepting groove, and described snap ring is housed in the described accepting groove, and described liner is between described snap ring and described sealing cover, and be housed in the described sealing cover, an end of described sealing cover is plugged in the described accepting groove.
Further, described snap ring is provided with annular distance, and described annular distance periphery is provided with some oil grooves, and described oil groove is connected with the bi-side of described snap ring.
Further, described sealing cover is the straw hat shape.
In sum, the utility model oil-impregnated bearing is set in by described seal ring on the end of described bearing body, and described annular protrusion is plugged in the described snap groove, thereby better tightness, can prevent the leakage of lubricant oil fully.

Embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reached, function, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
See also Fig. 1 to Fig. 4, the utility model oil-impregnated bearing comprises bearing body 1, seal ring 2, snap ring 3, liner 4 and sealing cover 5, and described bearing body 1 is provided with axially extended perforation 11, and described perforation 11 extends to the both ends of the surface of described bearing body 1.One end of described bearing body 1 is provided with annular protrusion 12, and the axle center of the center of described annular protrusion 12 and described bearing body 1 is on same straight line.One end of described bearing body 1 is provided with accepting groove 13, and this accepting groove 13 is formed to its peripheral recesses by an end of described perforation 11.
A side adjacent with described bearing body 1 of described seal ring 2 is provided with snap groove 21, and this snap groove 21 is interconnected with the circle hole 22 of seal ring 2, and corresponding with described perforation 11.Described seal ring 2 is set on the end of described bearing body 1, and described annular protrusion 12 is plugged in the described snap groove 21.Described snap ring 3, liner 4 and sealing cover 5 are stacked in the other end of described bearing body 1 mutually.
Described snap ring 3 is housed in the described accepting groove 13, and described liner 4 and is housed in the described sealing cover 5 between described snap ring 3 and described sealing cover 5, and an end of described sealing cover 5 is plugged in the described accepting groove 13.Described snap ring 3 is provided with annular distance 31, and described annular distance 31 peripheries are provided with some oil grooves 32, and described oil groove 32 is connected with the bi-side of described snap ring 3.By described oil groove 32 is set, thereby can reduce the frictional force of bearing and described liner 4 and snap ring 3, thereby can improve working life.
Described liner 4 is made by high abrasion resisting material.Described sealing cover 5 is the straw hat shape, by this straw hat shape structure, thereby sealing cover 5 and described bearing body 1 is fitted tightly.When using the utility model, rotating shaft is inserted the circle hole 22 of described seal ring 2 and is passed the perforation 11 of described bearing body 1 and the annular distance 31 of snap ring 3, directes reach to withstand on the described liner 4.When described rotating shaft is rotated,, thereby can prevent oil leakage by the sealing of described seal ring 2.
In sum, the utility model oil-impregnated bearing is set on the end of described bearing body 1 by described seal ring 2, and described annular protrusion 12 is plugged in the described snap groove 21, thereby better tightness, can prevent oil leakage fully.
The above embodiment has only expressed a kind of mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with claims.
