Abstract
The utility model discloses a sealed double-row deep groove ball bearing which comprises an inner ring, an outer ring, dustproof covers and a plurality of steel balls. The axial length of the inner ring is the same with the length of the outer ring; the inner surface of the outer ring and the outer surface of the inner ring are respectively provided with two rows of grooves; the steel balls are clamped in the grooves between the inner ring and the outer ring; the two sides of the steel ball are respectively provided with a retainer; the two sides of the groove of the outer ring are respectively provided with a clamping slot; and the dustproof covers are covered outside the retainers and are clamped in the clamping slots of the inner surface of the outer ring. The carrying capability of the sealed double-row deep groove ball bearing is enlarged; the sealing performance of the sealed double-row deep groove ball bearing is improved and the service life of the sealed double-row deep groove ball bearing is prolonged.
Description
Technical field
The utility model relates to a kind of sealing biserial deep groove ball 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.Exist the bearing carrying capacity can not satisfy the demand of main equipment in the existing technology.
The model utility content
The utility model provides a kind of sealing biserial deep groove ball bearing that strengthens carrying capacity, improves sealability.
The utility model technical solution problem provides following scheme:
A kind of sealing biserial deep groove ball bearing comprises inner ring, outer ring, dust cover and several steel balls, and the axial length of said inner ring is identical with outer ring length; Said inner surface and inner ring outer surface are respectively equipped with two row grooves; Said steel ball is fastened in the groove between the inside and outside circle, and said steel ball both sides are separately installed with retainer, and the groove both sides of said outer ring are established draw-in groove respectively; Said maintenance is covered with dust cover, and said dust cover is fastened in the draw-in groove of inner surface.
The utility model is provided with two row grooves between Internal and external cycle when design, several steel balls are installed in groove, and dust cover is installed between Internal and external cycle, has effectively guaranteed to avoid falling into dust on the steel ball between the Internal and external cycle, influences the life-span of bearing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; A kind of sealing biserial deep groove ball bearing comprises inner ring 1, outer ring 2, dust cover 3 and several steel balls 4, and the axial length of said inner ring 1 is identical with outer ring 2 length; Said outer ring 2 internal surfaces and inner ring 1 outer surface are respectively equipped with two row grooves 5,6; Said steel ball 4 is fastened in inside and outside circle 1, the groove between 25,6, and said steel ball 4 both sides are separately installed with retainer 7, and groove 6 both sides of said outer ring 2 are established draw-in groove 8 respectively; Said retainer 7 is covered with dust cover 3, and said dust cover 3 is fastened in the draw-in groove 8 of outer ring 2 internal surfaces.
