Problems solved by technology

[0002] The rotating shaft in the traditional rotating system is more prone to radial runout and axial jolting, resulting in a decrease in accuracy and serious wear of the rotating shaft, so the service life of the traditional rotating system needs to be improved
[0003] In addition, in the traditional rotating system, there is a disadvantage that the external circuit of the rotating shaft and the internal circuit of the rotating shaft cannot maintain long-term gap-free contact
There are also shortcomings such as elastic-plastic deformation of the contact surface, which makes the contact of the contact surface unreliable, the shaft jumps, and affects the machining accuracy or the reliability and life of the conductivity and diversion.

Abstract

The invention provides a nested high-reliability contact rotation system and a combined system and a method thereof. A single motion contacting body, multiple motion contacting bodies or multiple motion contacting bodies contacting one another as a whole is / are in contact with a first contacted body and a second contacted body under a force applied by a motion contacting body force applying mechanism. Motion contacting bodies like ball-shaped contacting bodies ensure that rotating bodies rotate relatively through gap-free contact, and make rotating bodies free of gap jump. The ball-shaped contacting bodies ensure that rotating bodies are not affected by relative rotation wear of the contact surfaces and are always in contact through motion following, ensure contact, and can be used for conducting. Multiple fulcrums can be obtained through multiple ball-shaped contacting bodies, so rotating bodies are aligned stably and rotate smoothly. Rotating bodies do not produce axial endplay under the condition of no radial run-out. Controlled movable contact can be easily realized.

technical field [0001] The invention relates to a contact rotation system, in particular to a nested high-reliability contact rotation system and a combined system and method thereof. Background technique [0002] The rotating shaft in the traditional rotating system is more prone to radial runout and axial jolting, resulting in a decrease in accuracy and serious wear of the rotating shaft, so the service life of the traditional rotating system needs to be improved. [0003] In addition, in the traditional rotating system, there is a disadvantage that the contact between the external circuit of the rotating shaft and the internal circuit of the rotating shaft cannot be maintained for a long time without gaps. There are also shortcomings such as elastic-plastic deformation of the contact surface, which makes the contact of the contact surface unreliable, the shaft jumps, and affects the machining accuracy or the reliability and life of the electrical conduction and diversion....
