Dismantling device for rolling elements of bearing cage

Abstract

The invention discloses a device for unpacking the rolling body of a bearing cage, which comprises a base, a support frame is arranged on the base, a pressure applying mechanism is arranged on the support frame, and the pressure applying mechanism includes a The movable bolt, the lower end of the movable bolt is vertically provided with an extension rod that can be pressed against the rolling body, the upper end surface of the base is provided with a chute, and a pair of cage shafts are slidably provided in the chute The clamping plate is limited to the position, and the clamping plate is fixed in the chute by a fixing member. The invention provides a rolling body dismounting device of a bearing cage which has simple structure, uniform force, is not easy to slip, and reduces damage and deformation of the surface of the rolling body and the cage.

Description

technical field [0001] The invention relates to a device for unpacking rolling elements of a bearing cage. Background technique [0002] The cage (that is, the bearing cage, also known as the bearing cage) refers to the bearing parts that partially wrap all or part of the rolling elements and move with them, to isolate the rolling elements, and usually guide the rolling elements and keep them in the bearing Inside. [0003] At present, such as in needle roller bearings, there is an interference fit between the needle roller and the cage. To realize the needle roller falling off the cage, a certain force must be applied to the end surface of the roller. However, during the disassembly process, due to Uneven application of force can easily lead to deformation of the cage and damage to the surface of the needle roller after the force is applied. After disassembly, the accuracy of the needle roller and the size of the cage cannot be guaranteed, resulting in changes in the size ...

Problems solved by technology

[0003] At present, such as in needle roller bearings, there is an interference fit between the needle roller and the cage. To realize the needle roller falling off the cage, a certain force must be applied to the end surface of the roller. However, during the disassembly process, due to Uneven application of force can easily lead to deformation of the cage and damage to the surface of the needle roller after the force is applied. After disassembly, the accuracy of the needle roller and the size of the cage cannot be guaranteed, resulting in changes in the size of the sample, making it impossible to measure accurately Unqualified sample delivery of new products caused by unqualified values ​​or dimensions can easily affect subsequent test results

In addition, this method is very unsafe to a certain extent, because during the disassembly process of the metal cage, it is often necessary to use tools (such as a screwdriver) to disassemble the needle roller, but because there is no good force point to ensure disassembly The normal trajectory of the tool is easy to slip off on the needle roller, thus acting on the hands of the dismantling personnel, causing personal injury
