Abstract
The utility model discloses a sealing ring bearing, which comprises an inner ring, an outer ring, a sealing ring and several steel balls; one end of the inner ring is aligned with one end of the outer ring; the length at the axial direction of the inner ring is longer than that of the outer ring; the external surface of one end of the inner ring and the interior surface of the outer ring are equipped with grooves; the steel ball is fastened in the grooves between the inner ring and the outer ring; the double sides of the steel ball are respectively equipped with two half retainer; the double sides of the groove of the outer ring are respectively equipped with a channel section; the external periphery of the sealing ring is provided with a flanging crimping; and the sealing ring is fastened in the channel section on the inner surface of the outer ring. The sealing ring bearing has the advantages of good sealing and firm connection without sliding.
Description
Technical field
The utility model relates to a kind of sealed bearing.
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.The utility model provides a kind of novel Placement of retainer.It is firm inadequately to exist bearing and axle directly to be connected in the existing technology, causes phenomenon such as the easy landing of bearing to cause the accident, the appearance accident.
The model utility content
The utility model provides a kind of good airproof performance, is connected firmly, is difficult for the sealed bearing of landing.
The utility model technical solution problem provides following scheme:
A kind of sealed bearing; Comprise inner ring, outer ring, seal ring and several steel balls, said inner ring aligns with outer ring one end, and the axial length of said inner ring is longer than the axial length of outer ring; The one end outer surface of said inner ring and the internal surface of outer ring are provided 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, and the groove both sides of said outer ring are established draw-in groove respectively; The outward edge of said seal ring is provided with the crimping of outward flanging, and said seal ring is fastened in the draw-in groove of inner surface.
Said seal ring is a butyronitrile rubber, perhaps other sealing materials
The utility model adopts the length lengthening with inner ring; Like this at inner ring with when the outer surface of axle combines, area of contact improves greatly, makes can be the firmly firmly low last difficult drop-off that be installed in of bearing; And adopt the rubber seal sealing, sealability improves greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, a kind of sealed bearing comprises inner ring 1, outer ring 2, seal ring 3 and several steel balls 4; Said inner ring 1 aligns with outer ring 2 one ends; The axial length of said inner ring 1 is longer than the axial length of outer ring 2, and an end outer surface of said inner ring 1 and the internal surface of outer ring 2 are provided with groove 5,6, and said steel ball 4 is fastened in inside and outside circle 1, the groove between 25,6; Said steel ball 4 both sides are separately installed with two halves retainer 7; Groove 6 both sides of said outer ring 2 are established draw-in groove 8 respectively, and the outward edge of said seal ring 3 is provided with the crimping of outward flanging, and said seal ring 3 is fastened in the draw-in groove 8 of outer ring 2 internal surfaces.
