Abstract
The utility model discloses a semi-closed deep groove ball bearing, which comprises an inner ring, an outer ring, sealing rings and a plurality of steel balls, wherein the axial length of the inner ring is longer than the axial length of the outer ring; the outer surface of one end of the inner ring and the inner surface of the outer ring are provided with grooves, and the steel balls are clamped in a groove between the inner ring and the outer ring; one side of the inner ring and one side of the outer ring are provided with sealing baffle plates, and two sides of each steel ball are respectively provided with two half retainers; the left side of the groove of the outer ring is provided with a card trough, and the outer edges of the sealing rings are provided with curling sides flanging outwards; and the sealing rings are clamped in the card troughs of the inner surface of the outer ring. The semi-closed deep groove ball bearing adopts a semi-closed structure, so that the sealing performance of the bearing is ensured, and the working time in one-time use process of the bearing is prolonged.
Description
Technical field
The utility model designs a kind of semi-enclosed 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 adopts semi-enclosed structure, has guaranteed bearing and outside area of contact, the working life of having improved bearing.
The model utility content
The utility model provides a kind of employing semi-enclosed structure, has guaranteed the semi-enclosed deep groove ball bearing of sealability of bearing.
The utility model technical solution problem provides following scheme:
A kind of semi-enclosed deep groove ball bearing; Comprise inner ring, outer ring, seal ring and several steel balls, the axial length of said inner ring is longer than the axial length of outer ring, and an 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; One side of said Internal and external cycle is established sealing baffle, and said steel ball both sides are separately installed with the two halves retainer, and draw-in groove is established in the groove left side of said outer ring; 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.
Be connected together through claw between said two and half retainers.
The utility model adopts semi-enclosed structure, adopts sealing baffle that one side sealing of bearing is got up at an end of bearing, and opposite side is installed seal ring, compares existing technology, and be improved the working life of bearing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; A kind of semi-enclosed deep groove ball bearing comprises inner ring 1, outer ring 2, seal ring 3 and several steel balls 4, and the axial length of said inner ring 1 is longer than the axial length of outer ring 2; The one end outer surface of said inner ring 1 and the internal surface of outer ring 2 are provided with groove 5,6; Said steel ball 4 is fastened in inside and outside circle 1, the groove between 25,6, and a side of said Internal and external cycle 1,2 is established sealing baffle 7, and said steel ball 4 both sides are separately installed with two halves retainer 8; Draw-in groove 9 is established in groove 6 left sides of said outer ring 2; The outward edge of said seal ring 3 is provided with the crimping 10 of outward flanging, and said seal ring 3 is fastened in the draw-in groove 9 of outer ring 2 internal surfaces, is connected together through claw 11 between said two and half retainers 8.
Claims (2)
