Description

Technical Field

[0001] The utility model belongs to the technical field of bearings and relates to a bearing, in particular to a high-stability bearing. Background Art

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing cage (i.e. bearing cage, also known as bearing retainer) refers to the bearing part that partially wraps all or part of the rolling elements and moves with them, which is used to isolate the rolling elements, and usually guides the rolling elements and keeps them in the bearing.

[0003] Existing bearing cages are usually fixed with rivets after installation. This means that when the bearing is in use, if the cage, ball or shaft seat is damaged, it means that the entire bearing must be replaced. The reason is that the cage is difficult to remove after being fixed. In order to save maintenance time, the entire bearing is replaced, which is undoubtedly a waste of resources. Summary of the invention

[0004] The utility model aims to provide a high-stability bearing in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a high-stability bearing, including a bearing body, characterized in that a bearing inner ring is arranged in the bearing body, a bearing outer ring is arranged at the upper end of the bearing body, the bearing outer ring and the bearing body are fixedly connected by fixing bolts, a plurality of balls are arranged on the bearing body, and a fixed shaft for installing the balls is fixedly arranged on the bearing body relative to the position of each ball, and the balls are respectively abutted against the bearing inner ring and the bearing body, the upper end of the balls are arranged in a planar structure, the upper end of the fixed shaft is provided with a positioning portion for positioning the balls, a rolling ball is arranged between the positioning portion and the balls, and the upper end of the balls is provided with a rolling ring groove for rolling the rolling column.

[0006] In the above-mentioned high-stability bearing, a first installation groove for installing the ball is provided on the outer peripheral wall of the inner ring of the bearing, and a second installation groove for installing the ball is provided on the bearing body.

[0007] In the above-mentioned high-stability bearing, a rolling groove 1 for balls to roll is provided on the inner ring of the bearing, and a rolling groove 2 for balls to roll is provided on the bearing body.

[0008] In the above-mentioned high-stability bearing, a fixing portion is fixedly provided on the bearing body, and a plurality of mounting holes are formed on the fixing portion.

[0009] Compared with the prior art, the high-stability bearing changes the structure of the bearing retainer installed on the original bearing ball. The balls rotate on the fixed shaft, making the inner ring of the bearing more stable during use. When one of the balls is damaged, there is no need to replace it as a whole, thereby reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 As shown, the high stability bearing comprises a bearing body 1, wherein the bearing body 1 is provided with a bearing inner ring 2, and the upper end of the bearing body 1 is provided with a bearing outer ring 3, wherein the bearing outer ring 3 and the bearing body 1 are fixedly connected by fixing bolts, and a plurality of balls 4 are provided on the bearing body 1, and a fixing shaft 5 for installing the balls 4 is fixedly provided on the bearing body 1 at a position relative to each ball 4, and the balls 4 are sleeved on the fixing shaft 5, and the fixing shaft 5 and the bearing body 1 are provided as an integral structure, and the balls 4 are respectively against the bearing inner ring 2 and the bearing body 1, and the upper end of the balls 4 is provided with a plane structure, and a positioning portion 6 for positioning the balls 4 is provided on the upper end of the fixing shaft 5, and a rolling ball 7 is provided between the positioning portion 6 and the balls 4, and a rolling ring groove for rolling the rolling column is provided on the upper end of the balls 4. The rolling balls 7 move on the rolling ring groove, and the rotation of the bearing inner ring 2 causes the balls 4 to rotate.

[0014] To be more specific, a first mounting groove for mounting the ball 4 is provided on the outer peripheral wall of the bearing inner ring 2, and a second mounting groove for mounting the ball 4 is provided on the bearing body 1.

[0015] In further detail, the bearing inner ring 2 is provided with a rolling groove 1 for the rolling of the ball 4, and the bearing body 1 is provided with a rolling groove 2 for the rolling of the ball 4. The ball 4 rotates under the rotation of the bearing inner ring 2, and rotates on the rolling groove 1 and the rolling groove 2 respectively.
