Maintenance of Single Row Ball Slewing Bearing
1. The mounting bracket of the single row ball slewing bearing (the seat underneath the lower surface of the ring gear and the seat on the upper surface of the inner race) must be rigid enough to be flattened. Assembly of Single Row Ball Slewing Bearing before the bearing should be subjected to stress treatment, to reduce the single row of ball slewing bearing bearing deformation. The contact surface of the bearing and the single row ball slewing bearing must be cleaned.

2. The use of noise should pay attention to changes in the torque and torque changes, if any abnormal phenomenon should be demolished.

3. Single row ball slewing bearing must be horizontal lifting or storage, not vertical lifting or storage, so as not to deformation.

4. Before the bolts are fully tightened, the meshing check of the gears shall be carried out. The meshing conditions shall be in accordance with the requirements of the gears: the contact spots on the tooth surface after the operation of the gears under slight braking are not in the direction of the tooth height Less than 25%, not less than 30% in the length of the teeth.

5. To ensure the reliability of the bolt work, to avoid the lack of bolts preload, single row ball slewing bearing work of the first 100 hours and 500 hours, Single Row Ball Slewing Bearing should be checked bolt preload torque. After each 1000 hours of work should be checked once the tightening torque.

6. Tighten the nut, the bolt threads and nuts should be coated with lubricating oil, and should be used in the circumferential direction of the torque wrench evenly tightened several times. Single Row Ball Slewing Bearing When tightening the last time, the tightening torque on each bolt should be substantially uniform.

7. In the single row of ball slewing ring gear on the surface of the raceway on the surface of the uniform distribution of the four oil cup, which added to the raceway grease. Under normal circumstances, single row ball slewing bearing 50 hours lubrication time. Every time the fuel must be added, until the grease from the seal so far.

8. Idle found loud. Single Row Ball Slewing Bearing Just like the mountain bike shift the same as the voice of Kappa Kappa. And the phenomenon is very serious. Initially thought that the tower crane inside the daughter of broken teeth. Or the cards of the cards are broken.
