Description

Low-abrasion self-lubricating wind power yaw slewing bearing structure Technical Field The utility model relates to the technical field of wind power yaw, in particular to a low-abrasion self-lubricating wind power yaw slewing bearing structure. Background The wind power yaw slewing bearing structure is a supporting structure used for connecting a cabin and a tower in a wind turbine generator and realizing yaw movement of the cabin, and mainly has the functions of supporting the weight of the cabin and blades and transmitting the loads to the tower, and is also responsible for bearing complex loads such as acting force of wind on the blades and torque generated by the operation of the cabin. In the prior art, through the flange type slewing bearing of search patent bulletin number CN215487269U, including ring flange, rotating assembly and seal assembly, rotating assembly is located ring flange's upper surface center department, seal assembly joint is at rotating assembly's upper surface, the inner wall fixed mounting of inner circle has last go-between, the surface fixed mounting of outer lane has down the go-between, the upper surface of go-between has evenly seted up the rotation groove, the inside rotation in rotation groove is connected with first ball, realizes the effect of reducing wearing and tearing, but the device does not set up the structure of automatic lubrication, can not realize that outer body circle and interior body circle in the bearing structure can all realize the effect of automatic lubrication to can exert an influence on mechanical equipment's performance and equipment, reduce availability factor. Disclosure of utility model The utility model aims to provide a low-wear self-lubricating wind power yaw slewing bearing structure which solves the problems that the device is not provided with an automatic lubricating structure and can not realize the effect of automatic lubrication of an outer body ring and an inner body ring in the bearing structure, thereby influencing the performance and equipment of mechanical equipment and reducing the use efficiency. In order to achieve the above-mentioned purpose, provide a low wearing and tearing self-lubricating formula wind-powered electricity generation driftage slewing bearing structure, including becoming oar bearing, it is provided with a plurality of paddles to become oar bearing outside terminal surface, it is fixed with main shaft bearing to become oar bearing back, main shaft bearing back has slewing bearing main structure through transverse bolt connection, slewing bearing main structure includes the outer lane, the outer lane inboard is fixed with the inner circle, the outer lane top is provided with lubricating structure, lubricating structure includes the lubrication box, lubrication box outside right-hand member is fixed with the oil filler pipe, oil filler pipe left side runs through to lubrication box inboard, lubrication box bottom is fixed with the oil outlet pipe, oil outlet pipe one end runs through to lubrication box inboard, and the other end runs through to the outer lane is inside.
