Description

Technical Field

[0001] The utility model relates to the field of needle roller bearings, in particular to automatic needle-installing equipment for needle roller bearings. Background Art

[0002] In the production of needle roller bearings, it is usually necessary to add needle rollers to the needle roller bearings because these needle rollers can provide efficient rolling motion inside the bearings. The original design intention of the needle roller bearings was to provide higher load-bearing capacity and lower friction in applications where space is limited. The slender shape of the needle rollers enables them to arrange more rolling elements in a limited space, thereby significantly improving the load-bearing capacity of the bearings. In addition, the rolling friction characteristics of the needle roller bearings give them a lower friction coefficient at high-speed rotation, thereby reducing energy loss and heat generation. Therefore, the insertion of needle rollers is not only to achieve rolling motion, but also to improve the overall performance of the bearing and ensure that it can operate efficiently and stably in various mechanical systems.

[0003] The thrust needle roller bearing automatic assembly machine with application number CN202320701634.4 after retrieval includes a base, the upper surface of the base is fixedly connected with a pushing mechanism, the output end of the pushing mechanism is fixedly connected with an assembly mechanism, and the side of the assembly mechanism is fixedly connected with a return mechanism. The utility model simplifies the assembly equipment and occupies a small area. The retaining frame is pushed by the pushing mechanism. When the assembly mechanism is assembled, the pushing mechanism can push the next assembly process once. The assembly time is short. Through the set discharge pipe and rotating motor, the needle roller is output from the discharge pipe to the assembly position, and the program is controlled according to the product hole position. When the circumferential distribution hole position of the product is an even number, the program controls the rotating motor to rotate the corresponding angle and then stop, so that the needle rollers in the discharge pipes on both sides enter the assembly position for assembly, and repeat this process until the assembly is completed. It only takes half the time to complete an assembly, which improves production efficiency.

[0004] In the above scheme, the bearings need to be loaded manually, which consumes a lot of human resources. During assembly, the bearings need to push the retaining frame through a pushing mechanism. When the assembly mechanism is assembled, the pushing mechanism only needs to push once to proceed to the next assembly process. The assembly efficiency is low and only small batch production can be carried out. Therefore, the utility model aims to provide an automatic needle loading device for needle roller bearings.
