Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of bearing inner rings, and in particular to a bearing inner ring which is easy to disassemble. Background Art
[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibrations and noise are larger, and their prices are also higher. Rolling bearings generally consist of four parts: an outer ring, an inner ring, rolling elements and a cage. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. The inner ring refers to the bearing ring with the raceway on the outer surface.
[0003] For example, Chinese patent publication number CN207364109U discloses a bearing inner ring that is easy to disassemble, including a bearing inner ring body, a bearing inner ring rolling groove is arranged on the bearing inner ring body, a bearing outer ring is arranged on the outer side of the bearing inner ring body, and balls are installed between the bearing inner ring body and the bearing outer ring, a detachable slider body is arranged on the bearing inner ring body, an extended fixing plate is installed on the detachable slider body, a threaded nail fixing groove is arranged on the bearing inner ring body, a threaded nail is installed on the threaded nail fixing groove, and the detachable slider body is fixedly connected to the bearing inner ring body by the threaded nail.
[0004] The above application provides a removable slider body. When removing the bearing inner ring body, it is not necessary to forcibly remove it by external force. It is only necessary to remove the screw nails and push the removable slider body to the side to separate the removable slider body from the bearing inner ring body. The connection between the removable slider body and the bearing inner ring body in the above application depends on the screw nails, which are not strong enough and are easy to loosen during high-intensity work, and the bearing inner ring is easy to be damaged.
