Abstract

The utility model discloses edge dust cover in motor, comprise outer cover, velvet-like ring-like dust-proof cushion and clamping pad, outer cover and clamping pad clamp, formation can hold the cavity of velvet-like ring-like dust-proof cushion, on outer cover inwall lower plane and clamping pad, plane is provided with triangular form suspension column, velvet-like ring-like dust-proof cushion is arranged in this cavity, on outer cover inwall lower plane and clamping pad, the triangular form suspension column of plane forms profile of tooth staggered form clip to velvet-like ring-like dust-proof cushion, after adopting said structure design, effectively can fix suede and fill ring-like dust-proof cushion, on outer cover inwall lower plane and clamping pad, the triangular form suspension column of plane so firmly effectively can hand over the firmly velvet-like ring-like dust-proof cushion of mode clip again with flute profile, when this structure and product are acted on motor, just can stop that some sharp particle such as silt directly contact with sealing ring and cause it to wear and tear, greatly improve the useful life of motor.

Description

Edge dust cover in motor

Technical field

The utility model relates to edge dust cover in motor.

Background technology

Motor overall performance is the comprehensive embodiment of each associated components performance, the performance of parts also directly affects quality level and the life-span of complete machine simultaneously, sealing ring and bearing are as the main parts size on complete machine, it is the body supports of its motor operation, but existing motor itself does not seldom even have for the protective device of motor, when motor works under some environment with silt, silt easily proceeds to its inside, direct wearing and tearing are caused to sealing ring and bearing, thus affect the normal work of motor, therefore be necessary to be improved, particularly at some special machines because the relation of its function and local space lacks protection more, and the present invention can fill up its mass defect produced because designing deficiency completely, significantly improve and extend sealing ring, the useful life of bearing and complete machine.

Summary of the invention

For above-mentioned technological deficiency, the utility model proposes edge dust cover in motor.

In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:

Edge dust cover in motor, comprise outer cover, velvet-like ring-like dust-proof cushion and clamping pad, described outer cover and clamping pad clamp, formation can hold the cavity of velvet-like ring-like dust-proof cushion, on described outer cover inwall lower plane and clamping pad, plane is provided with triangular form suspension column, described velvet-like ring-like dust-proof cushion is arranged in this cavity, and on described outer cover inwall lower plane and clamping pad, the triangular form suspension column of plane forms profile of tooth staggered form clip to velvet-like ring-like dust-proof cushion.

Further, the inner wall of end of described outer cover is provided with annular groove, and the outer peripheral face of clamping pad is provided with the bulge loop matched with annular groove.

Further, described outer cover, velvet-like ring-like dust-proof cushion and clamping pad are all designed to the inner circle that coordinates with axle.

Further, the outside of described outer cover step-like design ringwise.

The beneficial effects of the utility model are: after adopting said structure design, effectively can fix suede and fill ring-like dust-proof cushion, bulge loop on clamping pad can closely cooperate with the annular groove on end cap, form the folder stamen space that can be held velvet-like ring-like dust-proof cushion, outer cover inwall lower plane so firmly can live velvet-like ring-like dust-proof cushion by the effective mode clip intersected with flute profile with the triangular form suspension column of plane on clamping pad simultaneously, when this structure and product are acted on motor, just can stop that some sharp particle such as silt directly contact with sealing ring and cause it to wear and tear, particularly velvet-like ring-like dust-proof cushion also forms turnup structure along wearing direction of principal axis while being passed by motor reel simultaneously, can extend the life-span of self, greatly improve the useful life of motor, and reduce the generation of fault.2, because sealing ring belongs to rubber parts; can with grease lubrication during installation; when rubber parts and grease are directly exposed in the external world; or by muddy water Acidity of Aikalinity corrosion and air oxidation, UV cured; accelerate the aging of sealing ring and grease volatilization, thus destroy the sealing property of sealing ring, final acceleration motor bearing and motor damage; this product forms protection outward at sealing ring and grease, and many times of formulas can be become to extend its protective value.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

As shown in Figure 1, edge dust cover in motor, comprise outer cover 2, velvet-like ring-like dust-proof cushion 4 and clamping pad 6, described outer cover 2, velvet-like ring-like dust-proof cushion 4 and clamping pad 6 are all designed to the inner circle coordinated with axle, the outside step-like design ringwise of described outer cover 2, described outer cover 2 clamps with clamping pad 6, formation can hold the cavity of velvet-like ring-like dust-proof cushion 4, on described outer cover 2 inwall lower plane and clamping pad 6, plane is provided with triangular form suspension column (1, 5), described velvet-like ring-like dust-proof cushion 4 is arranged in this cavity, the triangular form suspension column (1 of plane on described outer cover 2 inwall lower plane and clamping pad 6, 5) profile of tooth staggered form clip is formed to velvet-like ring-like dust-proof cushion 4.The inner wall of end of described outer cover 2 is provided with annular groove, and the outer peripheral face of clamping pad 4 is provided with the bulge loop 3 matched with annular groove.

After adopting said structure design, effectively can fix suede and fill ring-like dust-proof cushion, bulge loop on clamping pad can closely cooperate with the annular groove on end cap, form the folder stamen space that can be held velvet-like ring-like dust-proof cushion, simultaneously outer cover inwall lower plane so firmly effectively can hand over the firmly velvet-like ring-like dust-proof cushion of mode clip again with flute profile with the triangular form suspension column of plane on clamping pad, when this structure and product are acted on motor, just can stop that some sharp particle such as silt directly contact with sealing ring and cause it to wear and tear, particularly velvet-like ring-like dust-proof cushion also forms turnup structure along wearing direction of principal axis while being passed by motor reel simultaneously, can extend the life-span of self, greatly improve the useful life of motor, and reduce the generation of fault.2, because sealing ring belongs to rubber parts; can with grease lubrication during installation; when rubber parts and grease are directly exposed in the external world; or by muddy water Acidity of Aikalinity corrosion and air oxidation, UV cured; accelerate the aging of sealing ring and grease volatilization, thus destroy the sealing property of sealing ring, final acceleration motor bearing and motor damage; this product forms protection outward at sealing ring and grease, and many times of formulas can be become to extend its protective value.

The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection range.
