Abstract
The utility model provides a ball bearing for a blender, which comprises an inner ring, an outer ring and balls arranged between the inner ring and the outer ring, wherein a groove allowing the balls to roll is arranged on the inner circumferential surface of the outer; a groove allowing the balls to roll is arranged on the outer circumferential surface of the inner ring; and a ball track formed by the inner ring groove and the outer ring groove is filled up with the balls in a way of being butted against one another. The utility model relates to an improvement on a ball bearing which is applied on a linkage shaft of a blender. Since no retainer is arranged, the entire ball track is filled up with the balls which are supported one another; and since the hardness of the inner ring, the outer ring and the balls is high, the compression resistance capability of the ball bearing is improved, and the service life of the bearing is prolonged. In addition, only damaged components need to be replaced when the ball bearing is damaged, thereby saving the time of maintenance and replacement.
Description
Technical field
The utility model relates to a kind of stirrer ball bearing.
Background technique
Conventional ball bearing mainly comprises four primary elements, i.e. ball, interior ring, outer shroud and retainer.Between ball and the ball spacing is arranged,, guarantee that it can not come off from the raceway that interior ring and outer shroud form by the fixing ball position of retainer.Retainer hardness is low than ball and interior ring, outer shroud, easily fracture.Conventional ball bearing is used under high temperature, the flue dust condition, the easy oil starvation of retainer, when oil starvation is serious retainer can with the ball locking, because the reaction force that is subjected to during stirrer work is big, can cause the retainer fracture, ball loses support and fixing, breaks away from from the raceway that inside and outside ring forms, and bearing life stops.The bearing of scrapping needs earlier the axle on the stirrer to be disassembled when changing, and bearing is unloaded from axle again, wastes time and energy.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of long service life at the above-mentioned deficiency of prior art, change stirrer ball bearing easily.
For achieving the above object, the technical solution of the utility model is: comprise interior ring, outer shroud and be located at ball between interior ring, the outer shroud; The inner peripheral surface of described outer shroud is provided with the groove that rolls for ball; The outer peripheral surface of ring is provided with the groove that rolls for ball in described; Described ball is filled in outer annular recess and the formed raceway of inner annular recess with reclining mutually each other.
Ring bottom is provided with the baffle ring that is used for preventing that ball from coming off from the raceway of interior ring and outer shroud formation in described.
The utility model is the improvement that is applied in the ball bearing on the heavy-duty motor couple axle to existing, owing to there is not retainer, ball is full of whole raceway, ball plays supporting effect each other, because the hardness of interior ring, outer shroud, ball is big, has improved the anti-extrusion ability of ball bearing, prolonged the working life (extending to more than 1 year) of bearing, simultaneously, the parts that only need change damage when occurring damaging get final product, and have saved the maintain and replace time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a sectional drawing of the present utility model.
Among the figure, 1, outer shroud, 2, interior ring, 3, ball, 4, baffle ring.
Embodiment
Among Fig. 1, Fig. 2, in the utility model comprises ring 2, outer shroud 1 and be located in ring 2, the ball between the outer shroud 1.The inner peripheral surface of outer shroud 1 is provided with the groove that rolls for ball, and the outer peripheral surface of interior ring 2 is provided with the groove that rolls for ball.Ball 3 is filled in interior ring 2 grooves and the formed raceway of outer shroud 1 groove with reclining mutually each other.The baffle ring 4 of a ring is arranged at interior ring 2 bottoms, and baffle ring 4 internal diameters are identical with interior ring 2 internal diameters.Outer shroud 1, interior ring 2 are fixed on ball 3 in the raceway of outer shroud 1, interior ring 2 compositions jointly with baffle ring 4.There is not retainer between outer shroud 1 and the interior ring 2; Do not have spacing between ball 3 and the ball 3, support mutually between the ball 3.The utility model because the hardness of interior ring 2, outer shroud 1, ball 3 is big, has improved the anti-extrusion ability of bearing in use, has prolonged the working life of bearing, and simultaneously, the parts that only need change damage when occurring damaging get final product.
