Rolling mill and end cover of bearing box thereof

Abstract

The invention discloses an end cover of a bearing box, which comprises a bottom cover (1) and a snap ring (2) arranged on the bottom cover (1), wherein the bottom cover (1) is provided with a drainage hole (3), and the inlet of the drainage hole (3) and the snap ring (2) are positioned at the same side of the bottom cover; and the bottom cover is also provided with a discharge conduit (4) communicated with the drainage hole (3). Due to the structural design of the end cover of the bearing box, the problems that the quality of a rolled product is influenced and the production cost is increased because used lubricating oil cannot be recycled and only can enter an oil rolling system can be effectively solved. The invention further discloses a rolling mill with the end cover of the bearing box.

Description

technical field [0001] The invention relates to the technical field of rolling equipment, in particular to an end cover of a bearing box, and also relates to a rolling mill with the above-mentioned end cover of the bearing box. Background technique [0002] The rolling mill is the equipment to realize the metal rolling process, which is mainly composed of rolls, roll bearings, racks, rail seats, roll adjustment devices, roll changing devices, etc. Among them, the roll bearing sleeve is set at both ends of the roll, mainly to support the roll and maintain the position of the roll. A cylindrical bearing box is also arranged outside the roll bearing, and the two ends of the bearing box are provided with end covers, such as figure 1 As shown, the end cover includes a bottom cover 01 and a snap ring 02, and the bearing box can wrap the pressure roller bearing. [0003] Since the working load of the roll bearing is heavy and changes greatly, the friction coefficient of the roll b...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the first object of the present invention is to provide an end cover of a bearing box. The structural design of the end cover of the bearing box can effectively solve the problem that the used lubricating oil cannot be recovered and can only enter the rolling oil system. However, the quality of the rolled product is affected and the production cost is increased. The second object of the present invention is to provide a rolling mill comprising the end cover of the above-mentioned bearing box
