Slewing Ring Process Flow Chart
1.Slewing ring handling in the loading and unloading process should be done gently, and non-throwing,hitting. Weighting more than 30kg slewing ring, it should be use lifting holes when in the handling process.
2.Slewing ring must be horizontal in the transport. For the non-wooden packaging of slewing ring, the bottom must be put in wooden pads and should have anti-slip steps.
3.For the diameter greater than 3000mmor easily deformed slewing ring, bearing should have assistant supporting.
12.Usage and maintenance
1.The slewing ring had been filed a few of No.3 lithium based grease in the race before delivery. Consumers should fill the new grease suitably according to different working condition before use it. Generally, it is necessary to fill in grease once every 100 hours for ball slewing ring, and once every 50 hours for roller slewing ring. When filling in lithium based grease, it must take the grease even till the grease out off from the sealing. The filling period should be shorten if there is the special working condition such as at the torrid zone, high humidity, severe dust, large temperature variation and long continuing working time. It should be filled with new grease before and after the machine being long time stop working.
2.The gear face exposed in air should periodically cleaned and spread with appropriate oil on it.
3.In general working condition, check the pre-tighten force of the bolts after first 100 working hours then check it every 500 hours of the slewing ring. It must be always kept enough pre-tighten force.
4.Cleaning the slewing ring with high-pressure water is not permissible during operation so as to avoid the water entering to the rolling race.
5.Stop and check the machine during operation if there is abnormal noise, vibration occurred or suddenly power rose. Remove the trouble or dismantle it for repairing if necessary. 6.Should not let the hard materials access or enter in the engaging area of the gear. 7.Regularly check the seal ring is that OK or not. Replace it if it is damaged and reset it when is is fallen.
8.Multi-slewing rings overlapping together horizontally must put at least 3-5 pads evenly in the direction of circumference between the slewing rings. And the upper and lower pads put in the circumferential direction of the position should be consistent. Slewing ring stand up is prohibited.
9.Slewing ring should be placed on non-corrosive medium, and stored in dry, flat indoor room, can not be soaked watered.
