Generally, large machinery requires various rotating operations, and only double-row slewing bearings can better cooperate with the machine's operation, so the maintenance of double-row slewing bearings is very important. How to maintain the slewing bearing of double-row volleyball?
During the maintenance of the double row ball slewing bearing, it is usually misunderstood by customers that the oil level of the double row ball slewing bearing is the same as the lubrication cycle of the arm and is pumped every day. In fact, it is just the opposite. If the lubrication cycle is too short, the bearing lubricant will be too much, leading to dust seal leakage. At the same time, with the leakage, impurities will enter the bearing, thereby damaging the normal operation of the bearing. Generally, the lubrication interval of rotating bearings is about once every 250 hours. At the same time, apply butter up and down, and beat the rotating machine at the same time. It is enough to hit the grease gun full every 15 degrees. The lubrication cycle can be adjusted based on the working intensity in different applications.
The maintenance cycle of the lubricating oil for the rotating motor is 1,000 hours. In daily operation, we must observe the amount of rotation oil on the dipstick. In some cases, we will find abnormal loss of lubricating oil. We must open the window of the large gear ring to check whether the lubricating oil has leaked into the large annular cavity through the seal.
The rotating platform includes the rotating gear ring, reducer, central component, etc. Generally, when we open the lifting rod next to the cover, we can observe the lubrication of the gear ring cavity and the wear of the gear. Therefore, it is necessary to regularly maintain the double row ball slewing bearing to ensure normal rotation.
Only correct maintenance can ensure that it works normally on the machine. Lubrication is the most important in maintenance. Without proper lubrication, the double-row ball slewing bearing not only works well, but also wears easily. Here, we show how to double the lubrication of the slewing bearing.
The double row ball slewing bearing is supplied with a small amount of grease rolling inwards when it leaves the factory, and users should replenish new grease according to different working conditions.
The raceway of the double row ball slewing bearing should be lubricated regularly. Generally, the steel ball support frame is oiled every 100 hours, and the roller support frame is oiled every 50 hours, as well as special working environments such as tropical, humid, dusty, large temperature difference, continuous operation, etc., which need to shorten the lubrication cycle.
Double row ball slewing bearings may not rotate under heavy workloads. It can be tilted by reducing the amplitude, adjusting the support legs, or moving the position of the chassis to help reduce the weight of the rotating bearing and complete the scheduled lifting operations. If the double row ball slewing bearing is already damaged, technical maintenance should be carried out to avoid further damage. Therefore, by carefully calculating the maximum load of each double row ball slewing bearing and selecting the appropriate one, the service life of the double row ball slewing bearing can be greatly improved.
