The utility model discloses a bearing that shield is difficult for dropping, comprises a bearing, the bearing is equipped with outer lane and inner circle, the inboard inside sunken boss that forms of terminal surface of outer lane, the boss evenly sets up the screw around the centre of a circle of outer lane, the lateral wall setting of inner circle centers on the recess in inner circle axle center, the bottom and the boss of recess are located same water flat line, be equipped with the ball between outer lane and the inner circle, set up the shield of ring shape jointly on the boss with in the recess, be equipped with noise damping layer in the shield, the through -hole around centre of a circle evenly distributed to the shield, the position of through -hole and screw is corresponding and pass through bolted connection. This bearing that shield is difficult for dropping utilizes through -hole and the screw on the boss on the shield to carry out the bolt fastening, recycles the wrap -around rubber sleeve elasticity in the shield outside for in the shield avris extrusion entering recess, make the shield more fixed, and the fine reduction bearing noise of the cotton layer ability of sound is inhaled in the setting in the shield.

Description

A kind of dust cap is difficult to the bearing dropped

Technical field

This utility model relates to field of bearings, is specifically related to the bearing that a kind of dust cap is difficult to drop.

Background technology

Bearing is a kind of important spare part in plant equipment in the present age.Its major function is to support machinery rotary body, reduces its motion During coefficient of friction, and ensure its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling bearing Class big with sliding bearing two.Wherein rolling bearing is the most normalized, seriation, but compared with sliding bearing its radial dimension, Vibration and noise are relatively big, and price is the highest.Rolling bearing is typically made up of outer ring, inner ring, rolling element and retainer four part, It is made up of outer ring, inner ring, rolling element, retainer, sealing, the big part of lubricating oil six strictly speaking.In simple terms, as long as Possess outer ring, inner ring, rolling element just to may be defined as rolling bearing.By the shape of rolling element, rolling bearing be divided into ball bearing and The big class of roller bearing two.And the dust that bearing dustproof cover is prevented from outside enters Bearing inner, affect the use of bearing.

Traditional bearing dustproof cover is firm not with the connected mode of bearing, and dust cap easily loosens and drops, to the use band of bearing Carry out a lot of trouble, be unfavorable for that user uses, easily increase use cost simultaneously.And traditional bearing is in the running, easily Produce noise.

Utility model content

The technical problems to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of dust cap is difficult to the axle dropped Holding, the use in providing amenities for the people, make that dust cap installs is more firm, reduces the noise that bearing sends.

In order to solve above-mentioned technical problem, this utility model provides following technical scheme: a kind of dust cap is difficult to the axle dropped Holding, including bearing, described bearing is provided with outer ring and inner ring, and cave inward inside the end face of described outer ring formation boss, described convex Platform is uniformly arranged screw around the center of circle of outer ring, and the lateral wall of described inner ring arranges the groove around inner ring axle center, described groove Bottom and boss are positioned on same level line, be provided with ball, described boss sets jointly with in groove between described outer ring and inner ring Putting the dust cap of annular shape, be provided with noise reduction layer in described dust cap, described dust cap is uniform-distribution with through hole around the center of circle, Described through hole is corresponding with the position of screw and is bolted.

Preferably, described screw and the quantity of through hole are with being set to four.

Preferably, the rubber-coated set in the outside of described dust cap.

Preferably, described noise reduction layer is set to acoustical cotton layer.

This utility model is reached to provide the benefit that: this dust cap is difficult to the bearing dropped, and is opened by the cycle surface at bearing If boss, a circle groove is set in the lateral wall of inner ring, utilizes the through hole on dust cap and the screw on boss to carry out bolt and fix, Outside recycling dust cap, cladding is rubber packed so that dust cap avris is squeezed in groove so that dust cap is more reinforced Fixed, and acoustical cotton layer is set in dust cap can well reduce bearing noise.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein be preferable to carry out Example is merely to illustrate and explains this utility model, is not used to limit this utility model.

Embodiment 1

As shown in Fig. 1 Fig. 5, a kind of dust cap of the present embodiment is difficult to the bearing dropped, including bearing 1, described bearing 1 Being provided with outer ring 2 and inner ring 3, cave inward inside the end face of described outer ring 2 formation boss 4, and described boss 4 is around outer ring 2 The center of circle be uniformly arranged screw 5, the lateral wall of described inner ring 3 arranges the groove 6 around inner ring 3 axle center, described groove 6 Bottom and boss 4 are positioned on same level line, are provided with ball 7, with recessed on described boss 4 between described outer ring 2 and inner ring 3 The dust cap 8 of annular shape is set in groove 6 jointly, in described dust cap 8, is provided with noise reduction layer 11, described dust cap 8 around The center of circle is uniform-distribution with through hole 10, and described through hole 10 is corresponding with the position of screw 5 and is connected by bolt 9.

Described screw 5 is same with the quantity of through hole 10 is set to four so that it is more preferable that dust cap 8 is fixed；Described dust cap 8 Outside rubber-coated set so that the outside of dust cap 8 has elasticity；Described noise reduction layer 11 is set to acoustical cotton layer so that dust-proof Subtracting of lid 8 is hot-tempered effective.

It should be noted that a kind of dust cap of this utility model is difficult to the bearing dropped, dust cap 8 is placed on boss 4, Dust cap 8 is due to the elasticity of rubber sleeve, fixing, by through hole 10 alignment boss 4 of dust cap 8 in can being squeezed into groove 6 On screw 5, utilize bolt 9 to be tightened so that dust cap 8 is fixed on boss 4, and owing to boss 4 is from outer ring The end face of 2 caves in and offers out, so do not interfere with any function that bearing is original.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this practicality new Type, although this utility model being described in detail with reference to previous embodiment, for a person skilled in the art, its Still the technical scheme described in foregoing embodiments can be modified, or wherein portion of techniques feature is carried out equivalent replace Change.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in Within protection domain of the present utility model.
