The 7201 dust bearing is a new type of dust bearing for electrostatic precipitators, consisting of a supporting wheel shaft, a supporting wheel, a sealing sleeve, a supporting wheel component, a support, a gasket, a locking sleeve, an open pin, a pin shaft, a retaining ring, a shield, etc. The supporting wheel is cylindrical in shape and fits with the gap between the supporting wheel shaft, with a groove that matches the sealing sleeve; There is a narrow diameter in the middle of the supporting wheel shaft, with retaining ring grooves and open pin holes at both ends. The support base plate is rectangular in shape, with fixed bolt holes at both ends and a rectangular hole for dust discharge in the middle. The wall panels on both sides are symmetrical, and there are inclined slots, locking sleeve holes, and pin shaft installation holes on the wall panels. The supporting wheel components and shields can be quickly installed through retaining rings, locking sleeves, pin shafts, gaskets, and split pins. The structural form adopted by the dust bearing can appropriately extend the service life of the dust bearing, and can easily and quickly install and remove all components, making installation, maintenance, and replacement very convenient.

Working principle of 7201 dust bearing:

A new type of dust bearing for an electrostatic precipitator is composed of a supporting wheel component, a supporting wheel, a sealing sleeve, a support, a gasket, a locking sleeve, an open pin, a pin shaft, a retaining ring, a cover, etc. The supporting wheel is cylindrical in shape and fits with the gap between the supporting wheel shaft, with a groove that matches the sealing sleeve; There is a narrow diameter in the middle of the supporting wheel shaft, with retaining ring grooves and open pin holes at both ends. The support base plate is rectangular in shape, with fixed bolt holes at both ends and a rectangular hole for dust discharge in the middle. The wall panels on both sides are symmetrical, and there are inclined slots, locking sleeve holes, and pin shaft installation holes on the wall panels. The supporting wheel components and shields can be quickly installed through retaining rings, locking sleeves, pin shafts, gaskets, and split pins. The structural form adopted by the new dust bearing can appropriately extend the service life of the dust bearing, and can easily and quickly install and remove all components, making installation, maintenance, and replacement very convenient.

In theory, bearings in dust cannot achieve the function of transmission. Moreover, bearings can also affect transmission. In order to reduce this effect and achieve good lubrication on high-speed shaft bearings, some bearings already have lubrication, called pre lubricated bearings, while most bearings have lubricating oil. When the load is running at high speed, friction not only increases energy consumption, but also makes it easy to damage the bearings.
