The dust-bearing is an important accessory of the electrostatic precipitator. Below is a detailed introduction about it:

• Structural Composition: The dust-bearing consists of a support wheel assembly formed by a support wheel shaft, support wheels, and sealing sleeves, as well as support seats, gaskets, locking sleeves, split pins, pin shafts, retaining rings, protective covers, etc. The support wheels are cylindrical, with a clearance fit to the support wheel shaft, and are equipped with grooves that match the sealing sleeves. The support wheel shaft has a narrow section in the middle, with retaining ring grooves and split pin holes at both ends. The base plate of the support seat is rectangular, with fixed bolt holes at both ends and a rectangular hole in the middle for discharging dust. The side plates are symmetrical, featuring inclined slots, locking sleeve holes, and pin shaft installation holes.

• Working Principle: The dust-bearing is mainly used to support the rapping shaft of the electrostatic precipitator, bearing radial loads. It ensures that the rapping shaft rotates in place without any lateral or longitudinal movement, guaranteeing the normal operation of the rapping shaft and thereby achieving the rapping and cleaning of the precipitator's plates and wires.

• Structure of the Dust-Bearing

  The dust-bearing consists of the following components:

  Support Wheel Shaft: Features a narrow section in the middle, with retaining ring grooves and split pin holes at both ends.

  Support Wheels: Cylindrical in shape, with a clearance fit to the support wheel shaft, and equipped with grooves that match the sealing sleeves.

  Sealing Sleeves: Used to prevent dust from entering the interior of the bearing.

  Support Seat: The base plate is rectangular, with fixed bolt holes at both ends and a rectangular hole in the middle for discharging dust. The side plates are symmetrical, featuring inclined slots, locking sleeve holes, and pin shaft installation holes.

  Other Accessories: Include gaskets, locking sleeves, split pins, pin shafts, retaining rings, protective covers, etc.
