Description

Technical Field

[0002] The main function of the power transmission device is to transmit the signal from the stationary device to the rotating device. It is used in photoelectric measurement, astronomical navigation, photoelectric search and other equipment. It is also a key component of various precision turntables, pipeline equipment and centrifuges in cutting-edge fields. The main detection parameter of the power transmission device is the dynamic contact resistance.

[0003] During the operation of the power transmission device, the brush wire and the slip ring of the power transmission device are always in a state of mutual friction. By disassembling the power transmission device that has been running for a long time, it is found that the slip ring of the power transmission device is seriously worn, which seriously affects the service life of the power transmission device. Based on the current theoretical and practical knowledge of the power transmission device, the contact pressure between the brush wire and the slip ring is the main factor affecting the service life and stability of the power transmission device. In the actual production process, after the brush wire is installed on the skeleton by gluing, it is necessary to manually adjust the opening angle of each brush wire so that the opening size between the brush wires is consistent and within a certain size range to ensure the consistency of the brush wire contact pressure. It is also necessary to adapt the brush wire skeleton to the conductive rod so that the contact position of the brush wire and the slip ring is at the bottom of the V-groove of the slip ring to ensure that the contact state of the brush wire and the slip ring is consistent. The whole process is particularly cumbersome, resulting in a long assembly cycle, which is not conducive to production needs. Summary of the invention
