The invention discloses a dustproof device of a hollow shaft type static pressure bearing. The dustproof device is composed of a sealing cover, a first partial dust remover and a second partial dust remover, and is covered on the static pressure bearing by the sealing cover; the first partial dust remover and the second partial dust remover are arranged on the sealing cover of the static pressure bearing in a pair; the sealing cover consists of two pairs of split sleeves, a left lower sealing cove, a right lower sealing cover and an upper sealing cover; the split sleeves and the sealing cover are provided with a labyrinth seal structure; the two partial dust removers respectively consist of hinged supports fixedly connected with the upper sealing cover; respective rolling brushes are tightly pressed on the outer circular cylindrical surfaces of the split sleeves along with the rotation of the hollow shaft by torsional springs and rocker arms of the first partial dust remover and the second partial dust remover, and the rolling brushes are quickly rolled through friction forces. According to the dustproof device, dust particles under the working environment of a ball grinder can be effectively prevented from entering a working space of the static pressure bearing.
Description
technical field [0001] The invention relates to a dustproof device, in particular to a dustproof device for a hollow shaft static pressure bearing. Background technique [0002] The specifications of ball mills continue to increase, and the requirements for the carrying capacity of hydrostatic bearings continue to increase. For ball mills that work in harsh environments with a lot of dust particles, the dustproof of hydrostatic bearings is very important. The existing hydrostatic bearings are The dust cover is not effective in preventing dust. Contents of the invention [0003] The object of the present invention is to provide a dust-proof device for a hollow shaft static pressure bearing with good dust-proof effect. [0004] The present invention is composed of a sealing cover, a first partial dust remover and a second partial dust remover. The sealing cover is composed of two pairs of split sleeves, a lower left sealing cover, a lower right sealing cover and an upper se...
