Description

A New Bearing Block Device for Hollow Shaft Hydrostatic Bearings

technical field

The utility model relates to a bearing seat device of a static pressure bearing, in particular to a novel bearing seat device of a hollow shaft type static pressure bearing.

Background technique

The specifications of the ball mill continue to increase, and the requirements for the load-carrying capacity of the hydrostatic bearing continue to increase. The limit function of the hinged bearing seat and the strong stiffness of the bearing seat are very important.

Utility model content

The purpose of the utility model is to provide a novel bearing seat device of a hollow shaft type hydrostatic bearing.

The bearing seat device of the present invention is composed of a bearing seat, a bearing body rotation limiting plate, a pin shaft, a ball stud bolt and a ball nut; the bearing seat is used to support the bearing body on both sides of the semi-outer cylindrical support with bearings. Body upright position fixed limit plate and bearing body maximum inclined position fixed limit plate, double clevis for hinged rotation limit plate and two-way positioning plate for positioning bearing body, bearing seat has weight-reducing holes.

The beneficial effects of the utility model: the bearing seat has a large strength-to-weight ratio and reliable position limiting.
