Abstract

The utility model discloses a bearing box of a rolling bearing. The bearing box of the rolling bearing comprises an upper bearing box and a lower bearing box. A plurality of holes are respectively arranged from top end to bottom end on a box body wall of the upper bearing box and a box body wall of the lower bearing box. The holes are distributed on the box body walls in a circumferential direction. One ends of the contiguous holes are communicated. The holes form an S-shaped return circuit. The starting end of the S-shaped return circuit is a liquid inlet, and the tail end of the S-shaped return circuit is a liquid outlet. Cooling liquid is filled in the S-shaped return circuit. According to the bearing box of the rolling bearing, the rolling bearing of an aluminum strip and foil mill can be quickly cooled, service life of the rolling bearing is prolonged, and production efficiency is improved.

Description

A kind of bearing housing of roll bearing

Technical field

The utility model relates to the bearing housing of a kind of aluminium strip, aluminium foil mill roll bearing.

Background technology

At present; Be not used in the cooling structure of cooling roll bearing on the bearing housing of most domestic aluminium strip, aluminium foil mill roll bearing, roll bearing is easy to heating in rotating at a high speed, and temperature raises and can not be cooled fast; Make the easy locking of roll bearing; Reduce the service life of bearing, increased maintenance cost, reduced production efficiency.

The utility model content

The purpose of the utility model is exactly to solve the problems referred to above that exist in the prior art; A kind of bearing housing of roll bearing is provided; Use the aluminium strip, aluminium foil mill roll bearing of this bearing housing can be, prolong roll bearing service life, enhance productivity by quick cooling.

For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of bearing housing of roll bearing; It comprises top bearing housing and lower bearing housing; On the upper and lower bearing housing box body wall of top bearing housing box body wall, from the top to the bottom, have a plurality of holes, a plurality of holes are distributed on the box body wall according to circumferencial direction; Adjacent holes one end is connected, and a plurality of holes form the serpentine loop, and the initiating terminal in serpentine loop is an inlet, and end is a liquid outlet, and serpentine is connected with cooling fluid in the loop.

Above-mentioned described serpentine is connected with the ROLLING OIL cooling fluid in the loop.

Because the utility model all is connected with circulating cooling liquid in top bearing housing box body wall and lower bearing housing box body wall; The heat that produces when cooling off fluid power with the rolling mill roll bearing working is taken away; Thereby cooled off the rolling mill roll bearing of work; Prolong roll bearing service life, reduced maintenance cost, improved production efficiency.Cooling fluid is selected ROLLING OIL for use, in the time of can avoiding cooling fluid to reveal to the pollution of ROLLING OIL.The utility model also can be used on the roll bearing of industry uses such as steel rolling.
