Abstract
The utility model discloses a bearing of a roller. The bearing comprises inner rings, outer rings, anti-dust caps and a plurality of steel balls and is characterized in that the axial length of each of the inner rings is longer than that of each 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, two semi-retainers are respectively arranged at two sides of each steel ball, clamping grooves are arranged at two sides of each of the grooves of the outer ring, the anti-dust caps are covered outside the semi-retainers and clamped in the clamping grooves on the inner surfaces of the outer rings. The bearing is simple in structure and convenient in installation, and stable work of the bearing can be ensured.
Description
Technical field
The utility model relates to a kind of roller bearing.
Background technique
At present, bearing is extensively applied to industry-by-industry, studies carefully it and is used for saying be to support, and promptly literal interpretation is used for holding axle, but this is the part of its effect, supports its essence and can bear radial load exactly.Also be appreciated that for it be used for fixing the axle.Be exactly that stationary axle makes it can only realize rotating, and control its axially with moving radially.It is exactly can not work that motor does not have the consequence of bearing at all.Because axle maybe be to the motion of any direction, and require axle to rotate during machine operation.Can not realize the effect of transmission theoretically, moreover, bearing also can influence transmission; On the bearing of high speed shaft, must realize good lubricating in order to reduce this influence, the bearing that has itself has had lubricated, is called prelubricated bearing; And most bearing must have lubricant oil; Load on when running up, because friction not only can increase energy consumption, more fearful is to be easy to damage bearing.The saying that changes sliding friction into rolling friction is unilateral, because kind of a thing that is sliding bearing is arranged.Existing technological middle (center) bearing exist structure single, existence can not be according to need carrying out structural change.
The model utility content
The utility model provide a kind of simple in structure, easy for installation, can guarantee the roller bearing that bearing can stable operation.
The utility model technical solution problem provides following scheme:
A kind of roller bearing comprises inner ring, outer ring, dust cover and several steel balls, and it is characterized in that: the axial length of said inner ring is longer than the 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, and the groove both sides of said outer ring are established draw-in groove respectively; Said half retainer is covered with dust cover, and said dust cover is fastened in the draw-in groove of inner surface.
The outer surface of said outer ring is provided with several spacing groove.
The utility model is offered several groove on the surface, outer ring of bearing, such groove can be guaranteed that bearing can be stablized and be sleeved on the axle securely after assembling is accomplished.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, a kind of roller bearing comprises inner ring 1, outer ring 2, dust cover 3 and several steel balls 4; The axial length of said inner ring 1 is longer than outer ring 2; Said outer ring 2 internal surfaces and inner ring 1 outer surface are respectively equipped with groove 5,6, and 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 two halves retainer 7; Groove 6 both sides of said outer ring 2 are established draw-in groove 8 respectively; Said half 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, and the outer surface of said outer ring 2 is provided with several spacing groove 9.
Claims (2)
1. a roller bearing comprises inner ring, outer ring, dust cover and several steel balls, and it is characterized in that: the axial length of said inner ring is longer than the 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, and the groove both sides of said outer ring are established draw-in groove respectively; Said half retainer is covered with dust cover, and said dust cover is fastened in the draw-in groove of inner surface.
