Description

Equipment for mounting balls on inner ring of tapered roller bearing Technical Field The utility model relates to assembly equipment of a bearing, in particular to equipment for mounting balls in an inner ring of a tapered roller bearing. Background In the production process of ball loading in the tapered roller bearing, the efficient and accurate assembly technology is important. At present, various technical solutions are available in the related art to improve assembly efficiency and quality. For example, the utility model patent application CN114803327a discloses an automatic assembly device and method for tapered roller bearings, which comprises a cage feeding device, a roller feeding device, a bearing inner ring assembly device, a bearing outer ring assembly device, a turntable workbench and other structures. Through the cooperative operation of the devices, the working procedures of retainer feeding, tapered roller assembly, inner ring assembly, outer ring assembly and the like can be automatically completed, and the production efficiency is improved to a certain extent. However, the technology still has some defects in the step of installing balls in the tapered roller bearing. In the ball assembly process, the existing assembly equipment has a relatively single filling mode for balls, and quick adaptation of retainers with different specifications is generally difficult to realize. As mentioned above, when the tapered roller is assembled to the cage, the roller feeding device in the above patent is based on a specific structural design and operation mode, and for the ball assembly scene, it cannot flexibly adjust the angle and speed of the ball, so that the accuracy and efficiency of the ball filling are affected when facing the cages of different sizes and structures. There is also room for optimization in the prior art for the positioning and transfer of the holders. In the CN114803327a patent, although the posture adjustment module is provided in the feeding process of the cage, in the whole assembly process, the positioning accuracy and stability of the cage when transferring from one station to another station still need to be improved. In the new method of fitting balls into the inner ring of a tapered roller bearing, the cage needs to be positioned precisely at the filling position to ensure that the balls can be filled into the respective accommodation positions of the cage without any error, and it is difficult in this respect to meet the requirements of higher precision in the prior art. Furthermore, existing assembly equipment has problems in terms of the synergy of the equipment as a whole. The fit between the different devices may be insufficiently tight, resulting in latency in the production process, reducing overall production efficiency. When the ball is arranged in the tapered roller bearing, the ball is fed and positioned from the retainer to the filling of the ball, all links need to be tightly connected, seamless connection of all links is difficult to realize in the prior art, and the production rhythm is influenced. The new tapered roller bearing inner race ball loading device is based on improvement and innovation of the defects of the prior art, and aims to provide a ball assembly solution which is more efficient, accurate and more adaptive.
