Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a bearing assembly device. Background Art

[0002] Bearings are an important component in mechanical equipment and are mainly used in parts that need to rotate. They are used to reduce rotational friction and support the rotating shaft. During the bearing production process, an assembly machine is required to assemble the inner ring, outer ring, rolling element and retaining frame.

[0003] In the prior art, when assembling the bearing, the rolling elements need to be placed between the inner ring and the outer ring, and then the inner ring and the outer ring are adjusted to a concentric position by extrusion. After the adjustment, the position of the rolling elements cannot be adjusted, causing the rolling elements to pile up or be too distributed. Therefore, the position of the rolling elements needs to be adjusted to keep them in a uniformly distributed position. On the one hand, it is convenient for the subsequent installation of the retaining frame and the rolling elements to be aligned. On the other hand, the force on the inner ring and the outer ring is uniform, avoiding the concentric offset of the inner ring and the outer ring in the later stage. In addition, bearings of different diameters need to adjust the distance between the same number of rolling elements to ensure the accuracy of the installation position of the rolling elements and the accuracy of the retaining frame fixing the rolling elements. Therefore, the position of the rolling elements needs to be adjusted according to the change of the bearing diameter. Utility Model Content

[0014] Beneficial effects: The present utility model discloses a bearing assembly device.

[0026] The output end of the moving cylinder 7 is fixedly connected to the lead screw 81. The nut, the partition plate 82, and the sleeve 8 are all threadedly connected to the lead screw 81. The collar 84 is arranged in the middle section of the partition plate 85 and is movably connected to the partition plate 85, enabling the partition plate 85 to rotate and slide when connected to the collar 84.
