Abstract
The utility model discloses a bearing provided with outer protective wheels, which comprises inner rings, outer rings and a plurality of steel balls, wherein a plurality of grooves are arranged on the outer surfaces of the outer rings, the outer protective wheels are sleeved on the outer surfaces of the outer rings, stop grooves are arranged on the outer surfaces of the outer rings, grooves are arranged on the inner surfaces of the outer rings and the outer surfaces of the inner rings respectively, the steel balls are clamped in the grooves among the inner rings and the outer rings, and two semi-retainers are respectively arranged at two sides of each steel ball. The bearing can effectively protect the outer rings of the bearing, prevent rusting, and is not easy to abrade.
Description
Technical field
The utility model relates to a kind of bearing that has outer guard sheaver.
Background technique
Bearing is a kind of very important component in the contemporary machinery, and its major function is supporting rotating shaft or other moving body, and guiding rotation or moving movement also bears by axle or parts on shaft transmission and the load of coming.Press the difference of motor element frictional property, bearing can be divided into two types on rolling bearing and sliding bearing.Each lasso all has the radial ball bearing of continuous ditch type raceway that cross section is approximately the girth 1/3rd of ball, is applicable to precision instrument, low noise motor, automobile, motorcycle and common mechanical etc., is a most widely used class bearing in the mechanical industry.Simple structure, working service is convenient.Mainly be used for bearing radial load, also can bear certain axial load, when the radial internal clearance of bearing strengthens, have the performance of angular contact ball bearing, can bear bigger axial load.Such pivot friction coefficient is little, and limit speed is high, and dimensional range and variation are various.Solid durable, highly versatile and low noise operation can be turned round and be easy under at a high speed and installed.Single-groove grooved ball bearing has the sealed type design in addition, can lubricate and service free again.Single-row band filling slot and two-row ball bearing are applicable to severe duty.Exist bearing in use to be prone to get rusty in the existing technology, be prone to be worn.
The model utility content
The utility model provides a kind of can effectively protect bearing outer ring, prevents to get rusty, the nonabradable bearing that has outer guard sheaver.
The utility model technical solution problem provides following scheme:
A kind of bearing that has outer guard sheaver; Comprise inner ring, outer ring and several steel balls, establish several grooves on the outer surface of said outer ring, be set with outer guard sheaver on the outer surface of said outer ring; The outer surface of said outer ring is provided with locking groove; Said inner surface and inner ring outer surface are respectively equipped with groove, and said steel ball is fastened in the groove between the inside and outside circle, and said steel ball both sides are separately installed with the two halves retainer.
Said outer guard sheaver adopts the PU material.
The utility model bearing foreign steamer is with the direct molding and forming of PU material, and anti-friction property is excellent especially, good hardness, and weatherability is good, has the incomparable characteristic of synthetic rubber.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; A kind of bearing that has outer guard sheaver comprises inner ring 1, outer ring 2 and several steel balls 3, establishes several grooves 4 on the outer surface of said outer ring 2; Be set with outer guard sheaver 5 on 2 outer surfaces of said outer ring; Said outer ring 2 internal surfaces and inner ring 1 outer surface are respectively equipped with groove 6,7, and said steel ball 3 is fastened in inside and outside circle 1, the groove between 26,7, and said steel ball 3 both sides are separately installed with two halves retainer 8.
Claims (2)
1. bearing that has outer guard sheaver; Comprise inner ring, outer ring and several steel balls; It is characterized in that: establish several grooves on the outer surface of said outer ring, be set with outer guard sheaver on the outer surface of said outer ring, said inner surface and inner ring outer surface are respectively equipped with groove; Said steel ball is fastened in the groove between the inside and outside circle, and said steel ball both sides are separately installed with the two halves retainer.
