Abstract

The utility model discloses a novel bearing block device of a hollow shaft type hydrostatic bearing. The novel bearing block device of the hollow shaft type hydrostatic bearing is composed of a bearing block, a bearing body rotary limiting board, a hinge pin, a ball head bolt and a ball head nut. A bearing body vertical-position fixed limiting board and a bearing body largest inclined-position fixed limiting board are arranged at the two sides of a semi-outer cylindrical surface support, used for supporting the bearing body, of the bearing block respectively; two lugs used for being hinged to the rotary limiting board are arranged at the two sides of the semi-outer cylindrical surface support, used for supporting the bearing body, of the bearing block respectively; two directional locating boards used for limiting the bearing body are arranged at the two sides of the semi-outer cylindrical surface support, used for supporting the bearing body, of the bearing block respectively. A lightening hole is formed in the bearing block. The novel bearing block device of the hollow shaft type hydrostatic bearing is large in the ratio of strength to weight and reliable in limiting.

Description

The novel bearing base device of hollow shaft type hydrostatic bearing

Technical field

The utility model relates to a kind of bearing holder device of hydrostatic bearing, particularly a kind of novel bearing base device of hollow shaft type hydrostatic bearing.

Background technique

The specification of pebble mill constantly increases, and the demands for bearing capacity of hydrostatic bearing is improved constantly, and the limit function of hinging supporting shaft bearing, the strong rigidity of bearing support are most important.

The model utility content

The purpose of this utility model provides a kind of novel bearing base device of hollow shaft type hydrostatic bearing.

This bearing holder device is made up of bearing support, bearing support rotary spacing plate, bearing pin, ball stud and bulb nut; The both sides that are used for half external cylindrical surface bearing of spring bearing body on the bearing support have the bearing support orthostatism fixedly limiting board and bearing support maximum inclination position fixedly limiting board, for the ears ring of hinged rotary spacing plate with for the two-way positioning plate of positioning bearing body, have lightening hole on the bearing support.

The beneficial effects of the utility model: this bearing support ratio of strength to weight is big, and is spacing reliable.
