Example 1

As shown in fig. 1 to 6, a bearing for a mixer, comprising an outer ring 100, an inner ring 110, a cage provided between the outer ring 100 and the inner ring 110, and a plurality of balls 130 provided on the cage 120, is characterized in that: the two ends of the outer ring 100 are extended with a blocking part 140 facing the axial direction of the outer ring 100. The inner ring 110 is located at the inner side of the outer ring 100, the cage 120 is located between the outer ring 100 and the inner ring 110, the balls 130 are uniformly arranged on the cage 120, and the blocking portion 140 is adapted to wrap the balls 130 between the outer ring 100 and the inner ring 110, so as to increase the bearing capacity of the outer ring 100.

The retainer 120 includes a left retainer 121 and a right retainer 122, and a plurality of mounting holes 123 adapted for placing the balls 130 are formed in the left retainer 121 and the right retainer 122, wherein the left retainer 121 and the right retainer 122 are attached to each other. The arrangement of the left cage 121 and the right cage 122 can increase the number of the balls 130 in the cage 120, so that the bearing can bear a larger bearing capacity, each of the mounting holes 123 is correspondingly provided with one ball 130, and the balls 130 rotate along the outer wall of the inner ring 110 in the mounting hole 123.

A spacer 150 is disposed between two adjacent balls 130, wherein one end of the spacer 150 abuts against the left cage 121 and the right cage 122, and the other end abuts against the inner ring 110. The spacer 150 may vary its thickness to adjust play, may bear both radial and bi-directional axial loads, and may limit bi-directional axial displacement of the outer race 100 within the bearing play.

The left retainer 121 and the right retainer 122 each comprise a clamping plate 124 and a baffle 125 fixedly connected with the clamping plate 124, the clamping plate 124 and the baffle 125 are connected to form an L shape, wherein the mounting hole 123 is arranged on the clamping plate 124; two baffles 125 are respectively disposed at both ends of the inner ring 110. The clamping plate 124 is suitable for opening the mounting hole 123, so that the ball 130 rotates in the mounting hole 123, and the baffle 125 is suitable for blocking impurities and particles with larger sizes, preventing the impurities and particles from entering the bearing and blocking the bearing.

Two grooves 111 are formed in the inner ring 110, wherein the two grooves 111 are respectively attached to the side walls of the balls 130 on the left and

right holders

121 and 122. The groove 111 is adapted to receive the ball 130 such that the ball 130 rotates within the groove 111 of the inner race 110.

The groove 111 is obliquely arranged, and one end of the groove 111, which is close to the spacer 150, is higher than one end of the groove 111, which is far away from the spacer 150. The grooves 111 are inclined so that the balls 130 are also inclined in the grooves 111, thereby increasing the area of the outer race 100 and increasing the bearing capacity.

The balls 130 on the left cage 121 and the right cage 122 are staggered. The staggered arrangement of the balls 130 can make the balls 130 stressed uniformly, and the service life of the bearing is prolonged.

The outer ring 100 comprises a left outer ring 101 and a right outer ring 102, clamping grooves 103 are formed in one surface, adjacent to the left outer ring 101 and the right outer ring 102, of each clamping groove 103, a clamping piece 104 is formed by splicing the two clamping grooves 103, and a fastener 105 is arranged in the clamping piece 104 so as to fixedly connect the left outer ring 101 with the right outer ring 102; the blocking portions 140 are disposed on outer end surfaces of the left outer ring 101 and the right outer ring 102. The left outer ring 101 and the right outer ring 102 are separately arranged, clamping grooves 103 are formed in one side, adjacent to the right outer ring 102, of each clamping groove 103, each clamping groove 103 is in a V shape, one side, adjacent to each clamping groove 103, of each clamping groove 103 is attached to form a clamping piece 104, each clamping piece 104 is in a W shape, each clamping piece 105 is located above each clamping piece 104, each clamping piece 104 is clamped by the corresponding clamping piece 105, two clamping grooves 103 are tightly attached together, namely, the corresponding clamping piece 105 is used for fixing the left outer ring 101 and the corresponding right outer ring 102 together, and the blocking portions 140 are arranged on the outer end faces of the left outer ring 101 and the right outer ring 102, so that the left retainer 121, the right retainer 122 and the corresponding balls 130 can be limited to rotate between the outer ring 100 and the inner ring 110.

The blocking part 140 includes an extension plate 141, and the extension plate 141 forms an arc surface with the inner walls of the left and right

outer rings

101 and 102 to be attached to the side wall of the ball 130. The thickness of the extension plate 141 is greater than that of the outer ring 100, so that the extension plate 141 receives a greater load, i.e., reinforces both sides of the outer ring 100, so that the outer ring 100 can receive a greater force.

The balls 130 are in a cylindrical state, and the diameters of the balls 130 decrease from the middle to the two sides. The diameter of the balls 130 decreases from the middle to the two sides, so that the balls 130 can be more attached to the inner walls of the left outer ring 101 and the right outer ring 102 and the extension plate 141, and thus the balls 130 do not separate from the outer ring 100 and the inner ring 110 when they rotate.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
