Compared with the prior art, the utility model discloses following beneficial technological effect has:
the utility model discloses only lubricate between rocking rod and the connecting axle through lubricated wearing layer, belong to self-lubricating, need not extra oiling lubrication, avoid causing lubricating oil and granule dust iron cut to mix into fatlute, influence the rotatory lubricity of connecting axle department rocking rod. On this basis, the pin sealing angle and the pin bolt sealing angle are just respectively sealed with the pin side chamfer and the bolt side chamfer, and the particle dust can be further prevented from being ironed and entering the connecting shaft. Greatly ensuring the rotating lubricating property of the swinging rod at the connecting shaft.
