The function of the bearing sleeve of the rotary level switch

　　In the structural design of the rotary paddle level switch, both bearing and sleeve components are used. Both the bearing and sleeve can bear the load of the shaft. The bearing is a split type, and when it rotates, the inner and outer rings of the bearing itself move relative to each other; while the sleeve is an integral structure, and when it rotates, the shaft and sleeve move relative to each other. It can be seen that the structures of the bearing and sleeve of the rotary paddle level switch are completely different. What are the functions of the two?

　　The bearing in the movement of the rotary paddle level switch is a part that connects the rotating parts and the stationary parts. It supports the rotating shaft and the parts on the shaft to maintain the normal operation and rotation accuracy of the shaft. Its function is to transfer the axial force and radial force of the rotating parts to the stationary parts, which is conducive to the smooth rotation between the parts.

　　The shaft sleeve of the rotary paddle level switch transmission part is mainly used for axial positioning, reducing shaft wear and shock absorption. The shaft and blades work in the material storage tank for a long time, and the shaft sleeve can prevent dust from entering the shaft and play a protective function. The shaft sleeve is usually used in places with low speed, high radial load and high clearance requirements, which is in line with the transmission principle of the rotary paddle level switch.
