Description

Wear-resisting formula tilting disk assembly Technical Field The utility model relates to the field of swashplates, in particular to a wear-resistant swashplate assembly. Background The tilting disk of the helicopter is a core component of a flight control system, and has the core function of converting pilot control input into periodic attack angle change of rotor blades, so that the precise control of the flight attitude and lifting of the helicopter is realized. In the chinese patent with the patent name CN206417188U, the built-in bearing structure of the inclined disc slave moving ring phase positioner mounting frame, the first phase positioner (first connecting arm) and the second phase positioner (first connecting arm) are connected through the cooperation of the first screw and the bearing, but in the long-term use process, the bearing is easy to wear and the guide pillar is damaged, and further the rotating disc in the inclined disc cannot synchronously follow the spindle to move, and the like, which more seriously causes the potential safety hazard of the helicopter in the use process. In summary, how to improve the wear resistance between the first connecting arm and the second connecting arm becomes a problem to be solved by researchers in the field. Disclosure of utility model The utility model aims to solve the technical problem of improving the wear resistance between a first connecting arm and a second connecting arm; in order to solve the technical problems, the utility model adopts the following technical scheme: The utility model relates to a wear-resistant tilting disk assembly which comprises a fixed disk, a rotating disk and a rotating disk, wherein the fixed disk is connected with a main shaft through a bearing and is connected with a shaft tube sleeved outside the main shaft through a limiter, the rotating disk is rotatably arranged with the fixed disk and is connected with the main shaft through a synchronizer, the synchronizer and the limiter both comprise a first connecting arm and a second connecting arm which are mutually hinged, first supporting legs are arranged on two sides of the end parts of the first connecting arm in an outward extending mode, first connecting holes are formed in the support in a penetrating mode, the end parts of the second connecting arm are located between the two first supporting legs, locking pieces penetrate through the first connecting holes of the two first supporting legs and the end parts of the second connecting arms, a jacket is arranged at the position of each first supporting leg, a self-lubricating sleeve is sleeved outside the jacket, and the self-lubricating sleeve is in contact with the inner wall of the first connecting holes.
