Calcium Carbonate Making Powder Machine bearing

          

SBM introduces some details about the bearings of Calcium Carbonate Making Powder Machine parts. Although the bearing is a small part of the Calcium Carbonate Making Powder Machine, these details are also minor problems, but often these details determine the equipment. The effect of the operation is good or bad, so everyone should pay special attention. Below, SBM elaborates on the details of the lubrication, sealing and assembly details of the Calcium Carbonate Making Powder Machine bearings:

Assembly requirements for Calcium Carbonate Making Powder Machine bearings:

First, the fit of the bearing ring and the shaft should be interference fit, and the tight fit of the outer ring and the bearing hole should be adopted.

Second, for bearings with higher rotational speed, the smaller the coaxiality deviation should be, it is recommended to control within 0.01.

Third, the use of reasonable bearing clearance to ensure the bearing stiffness, rotation accuracy and load carrying capacity, thereby extending bearing life.

Fourth, the use of high-precision bearings can reduce the centrifugal additional force applied to the bearings when the rotor rotates at high speed, and also ensure high speed.

Bearing analysis and selection of bearings in Calcium Carbonate Making Powder Machine

In the high-speed impact movement of the Calcium Carbonate Making Powder Machine, the lower bearing not only has to withstand the normal circumferential force and the tension of the belt, but also the gravity of the entire rotor, so the choice of the lower bearing should be able to withstand the axial force at the same time. And radial force angular contact ball bearings. While the upper bearing is only subjected to radial force, deep groove ball bearings with low cost but high rotation accuracy and high speed limit can be selected.

Bearing lubrication method selection

At present, the Calcium Carbonate Making Powder Machine bearings commonly used in the world are rolling bearings, and there are three lubrication methods: grease lubrication, thin oil lubrication and solid lubrication. The general lubrication method is determined based on the speed factor of the bearing rotation. However, due to the more comprehensive and effective lubrication of the thin oil lubrication method, and the convenient sealing and long replacement period, the thin oil lubrication is a mature and practical bearing lubrication method.

Calcium Carbonate Making Powder Machine bearing seal

Sealing plays a vital role in the prevention of mechanical products from “three leaks”, ensuring the normal lubrication action and safe operation of the equipment. The Calcium Carbonate Making Powder Machine has high requirements for sealing, especially the sealing requirements of the grinding roller bearing. The oil seal is arranged between the stationary and rotating parts, and is used for preventing the leakage of the lubricating oil and preventing the external dust, materials and the like from entering the inner cavity of the bearing chamber, and has the advantages of simple structure, good sealing performance, and the oscillation of the shaft and the eccentricity. It is widely used in the grinding roller bearing seal of Calcium Carbonate Making Powder Machine.
