[0002] TAROL bearings are often used in rail vehicles such as buses and trucks. They are easy and quick to install. They are indispensable parts in machinery and equipment. Once rusted, the friction coefficient will increase, noise will be generated, and the life of the bearing will be affected, which will in turn affect the normal operation of the entire machinery and equipment. They are also prone to damage or even fall off, which brings safety hazards to the operation and use of machinery and equipment, and sometimes even fatal effects. Therefore, in daily use, it is necessary to pay attention to the maintenance of bearings to avoid negative impacts of rusted bearings on machinery and equipment.

[0009] Furthermore, a protective cover is provided at one end of the transmission shaft, and the protective cover is located outside the wire brush.

[0010] Compared with the prior art, the beneficial effects brought about by the technical solution of the utility model are:

[0011] The base slide plate and the counterweight block of the utility model enable the wire brush to be flexibly positioned during the rust removal process and adapt to the deformation of the outer ring. During the rust removal process, the wire brush can fit the surface of the bearing outer ring with a constant force regardless of whether it contacts the high point or the low point of the outer ring, thereby achieving the effect of constant-force rust removal, avoiding excessive rust removal or inadequate rust removal, and achieving rust removal without dead ends.

[0016] Preferably, in the above device, two chains 4 may be provided, one end of each chain 4 is connected to the top of the base slide 3, and the other end is connected to the counterweight base 6 through a connecting rod 10, and connecting rods 10 are provided on both sides of the upper end of the counterweight base 6, and the base slide 3 can be driven to move up and down by adjusting the counterweight 5. The top plate of the support frame 1 may be provided with a gear 11 for guiding the chain 4, and each chain 4 is provided with at least one gear 11, which acts as a fixed pulley to prevent the chain 4 from deviating left and right.

[0017] Preferably, in the above device, two linear guide rails 2 can be arranged in parallel, and correspondingly, sliders for sliding along the linear guide rails 2 are fixed at both left and right ends of the inner side of the base slide plate 3, and can move up and down on the linear guide rails 2.
