Description
Technical Field
The present disclosure relates to guide bar structures, and particularly to a guide bar structure for a rotary connector.
Background
The rotary connector is composed of a stator and a rotor, wherein the stator is fixed on a wallboard, a base and the like at a relatively static place, and an electric signal wire connected with the stator passes out along a fixed wire tube. And the corresponding power conductors, electrical signal conductors, etc. to which the rotor is connected should rotate with the mechanism as the rotor rotates. In general, the transmission mechanism for providing the rotation power for the rotor has higher requirements on the coaxiality of the rotary connector, which causes a certain restriction on the working environment of the rotary connector and limits the volume and the action range. In the process of conducting hydraulic signals, the coaxiality requirement of the rotary connector is very high, if the coaxiality between the stator and the rotor cannot meet the requirement, the hydraulic components such as an oil seal, a Gelai ring and the like are worn, so that the service life of the rotary connector is shortened, and even the transmission quality of the hydraulic signals is affected. Even though the coaxiality of the stator and the rotor of the rotary connector mechanism reaches a very precise level, in the practical application process, uneven abrasion often occurs due to the phenomena of coaxiality error or gravity center deviation and the like between the transmission link of the mechanism to the rotor and the rotary connector, and the liquid ring conduction failure is caused.
Chinese patent document CN102822011a discloses a "rotary connector device". A stator and a rotor which rotates concentrically with respect to the stator and a steering gear are employed, and a torque transmission section which rotates together with the rotor and transmits a rotational torque of the steering gear to the angle detection rotary body is configured concentrically with the angle detection rotary body provided in the angle detection sensor which detects a rotational angle of the steering gear. This structure has high coaxiality requirements, and although the structure can play a good role in transmission on most rotating mechanisms, the structure has a great influence on the transmission capability of hydraulic signals when the environment is severe.
