Problems solved by technology

In order to prolong the service life of the bearings, most general bearings will install dust covers at both ends of the bearings, which can prevent dust or water and other debris from entering the inside of the bearings, prevent the bearings from rusting, and virtually extend the life of the

Example Embodiment

[0009] The present invention will be further explained below in conjunction with the drawings in the specification:

[0010] A bearing includes an inner ring 2 and an outer ring 1, a rolling element 3 is arranged between the inner ring 2 and the outer ring 1, and also includes a dust cover 4, which is clamped to the outer ring 1, There is a working gap between the dust cover 4 and the inner ring 2. The dust cover 4 is insulated from the outer ring 1. The dust cover 4 is provided with an electrostatic dust collector, and the electrostatic dust collector includes an electrostatic brush 5 , The electrostatic suction net 41, the electrostatic brush 5 is provided with bristles 51 that are in contact with the electrostatic suction net 41, and the electrostatic brush 5 is connected to the inner ring 2.

[0011] By adopting the above technical solution, the dust cover 4 has no contact with the inner ring 2 or outer ring 1 of the bearing, and has no effect on the normal operation of the bea...

Abstract

The invention relates to a bearing structure. It is characterized in that the dust-proof cover is insulated from the outer ring, and an electrostatic dust-absorbing device is provided on the dust-proof cover, and the electrostatic dust-absorbing device includes an electrostatic brush and an electrostatic dust-absorbing net. There are bristles in contact with the electrostatic dust collection net, and the electrostatic brush is connected with the inner ring. In the present invention, by adopting the above technical scheme, the dust cover has no contact with the inner ring or outer ring of the bearing, and has no influence on the normal operation of the bearing. The bearing and the dust cover are insulated and matched, so static electricity can be generated by friction on the dust cover. When the electrostatic device works through the bearing, the inner ring rotates. The brushes fixed on the inner ring and the electrostatic dust collection net on the dust cover rub each other to generate static electricity. The friction between the bristles and the electrostatic dust collection net is very small and can be ignored. Regardless, the generated static electricity absorbs nearby dust, reducing the probability of dust passing through the gap between the dust cover and the bearing, and the dustproof effect is good.

Description

Technical field [0001] The invention relates to a bearing structure. Background technique [0002] Bearings are used to determine the relative movement position of the rotating shaft and other parts, and are used as supporting or guiding parts. It is a component that fixes and reduces the friction coefficient of load during mechanical transmission. It can also be said that when other mechanical parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the shaft center position fixed. In order to prolong the service life of the bearing, the general bearing will install dust caps on both ends of the bearing, which can prevent dust or water and other debris from entering the bearing, can prevent the bearing from rusting, and extend the bearing invisibly The service life of the dust cover, but the common dust cover includes contact type and non-contact type, contact type, the dust cover will generate friction...
