Abstract
The utility model discloses a sealing cover of a hollow shaft type hydrostatic bearing. The dustproof device of the hollow shaft type hydrostatic bearing is composed of two pairs of split type sleeves, a lower left sealing cover body, a lower right sealing cover body and an upper sealing cover body, the split type sleeves are sleeved on the left side and the right side of a journal of a hollow shaft respectively in a hollow mode, the lower left sealing cover body and the lower right sealing cover body are mounted on a groundwork through foundation bolts, the lower left sealing cover body and the lower right sealing cover body are connected in a sealing mode through a bolt set, and the upper sealing cover body is arranged on the lower left sealing cover body and the lower right sealing cover body and is connected with the lower left sealing cover body and the lower right sealing cover body through a bolt set. The split type sleeves sleeved on the hollow shaft in the hollow mode are pulled towards the two sides to proper positions respectively, the bolt set at the connecting position of the split type sleeves is screwed down, the split type sleeves are made to be fixedly connected to the hollow shaft, and a labyrinth sealing structure is formed by the split type sleeves and the sealing cover. The dustproof device of the hollow shaft type hydrostatic bearing is compact in structure, convenient to assemble and disassemble and good in sealing effect.
Description
Technical field
The utility model relates to a kind of seal closure of hydrostatic bearing, particularly a kind of seal closure of hollow shaft type hydrostatic bearing.
Background technique
The specification of pebble mill constantly increases, the requirement of the bearing capacity of hydrostatic bearing improved constantly, and at the pebble mill that the more evil of dust granules is slightly worked in the environment, hydrostatic bearing dustproof most important, the dust-proof effect of existing hydrostatic bearing dust-proof cover is not good.
The model utility content
The purpose of this utility model provides a kind of seal closure of hollow shaft type hydrostatic bearing of good sealing effect.
The utility model is comprised of two pairs of opposite opened sleeves, lower-left seal closure, bottom right seal closure and upper seal closure; Two pairs of opposite opened sleeves are placed in respectively about neck of hollow shaft, lower-left seal closure and bottom right seal closure are installed on the ground by the stone bolt group, by the bolt group lower-left seal closure and bottom right seal closure are tightly connected, upper seal closure is installed on lower-left seal closure and the bottom right seal closure and by the bolt group and is tightly connected, two pairs of opposite opened sleeves that are placed on the quill shaft are pulled to the appropriate location to both sides respectively, tighten opposite opened sleeve joint bolt group, the opposite opened sleeve is fixed on the quill shaft, and opposite opened sleeve and seal closure are formed with the labyrinth seal structure.
The beneficial effects of the utility model: compact structure, mounting or dismounting are convenient, good sealing effect.
