Yuncheng 014.45.1800.001 slewing bearing factory direct sales

Yuncheng...slewing bearing factory direct sales/ ' (3,3,3) -. The installation support of the slewing bearing (slewing bearing) (the seat supporting the lower surface of the ring gear and the upper surface of the inner race The seat) must be sufficiently rigid and the mounting surface must be flat. Before assembling the slewing bearing, the bearing should be stress-relieved to reduce the deformation of the slewing bearing bearing. The contact surface between the support and the slewing bearing must be cleaned during assembly.
/ ' (3,3,3) - When using the tower crane, attention should be paid to changes in noise and rotational resistance torque. If there are any abnormalities, it should be dismantled and inspected.
/ ' (3,3,3) - The slewing bearing must be lifted or stored horizontally, and must not be lifted or stored vertically to avoid deformation.
/ ' (3,3,3) - Before the bolts are completely tightened, the gear meshing should be checked. The meshing condition should meet the requirements for gear accuracy: that is, the gear pair operates under slight braking and the rear teeth The contact spots distributed on the surface are not less than 3 in the height direction of the gear teeth and not less than 3 in the length direction of the gear teeth.
/ ' (3,3,3) - The tooth surface should be cleaned of debris once every shift and re-lubricated.
/ ' (3,3,3) -. In order to ensure the reliability of bolt work and avoid insufficient bolt pre-tightening force, the pre-tensioning of bolts should be checked separately during the first hour and after the slewing bearing is working. Tight torque. The preload torque should be checked every working hour thereafter.
/ ' (3,3,3) -. The bolts and nuts connecting the slewing bearing are all made of high-strength bolts and nuts, and double nuts are used to tighten and prevent loosening.
/ ' (3,3,3) - When tightening the nut, lubricating oil should be applied to the threads of the bolt and the end surface of the nut, and a torque wrench should be used to tighten symmetrically and evenly multiple times in the circumferential direction. During the final tightening, the pretightening torque should be roughly even on each bolt.
/ ' (3,3,3) -. Oil cups are evenly distributed on the upper surface of the ring gear of the slewing bearing in alignment with the raceway, thereby adding grease to the raceway. Under normal circumstances, the slewing bearing should be lubricated once every hour of operation. Each refueling must be sufficient until grease seeps out from the seal.
