Novel-structure bearing seat for four-row tapered roller bearings for rolling mill

Abstract

The invention provides a novel-structure bearing seat for four-row tapered roller bearings for a rolling mill, and relates to the technical field of bearing seats. The novel-structure bearing seat comprises a bearing bottom seat, an oil injection component and oil storage tanks. The left end and the right end of the top of the bearing bottom seat are connected with the left end and the right end of the bottom of a bearing top seat correspondingly, and the right end of the bearing top seat is connected with a clamping hook. The oil injection assembly is installed on the top side of the bearing top seat. The clamping hook is respectively connected with an arc-shaped spring and a manual bolt. The two oil storage tanks are in a circular arc shape, and the oil storage tanks are connected with the bearing bottom seat through rotary knobs. When the bearing top seat is rotationally buckled to the top of the bearing bottom seat, thrust is applied to the clamping hook through the arc-shaped spring, the clamping hook is driven to rotate leftwards, the bottom side of the clamping hook makes contact with the top side of a barb, the right end of the bearing top seat is fixed through the clamping hook, the stability of a bearing in the bearing top seat is guaranteed, and a bearing is easier and more convenient to disassemble, assemble and fix.

Description

technical field [0001] The invention belongs to the technical field of bearing housings, and more particularly relates to a bearing housing for four-row tapered roller bearings for rolling mills with a new structure. Background technique [0002] The bearing seat is a kind of support and fixed part that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation and convenient maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support It is the long-term bearing seat. [0003] The bearing seat can refer to the patent CN102852981B, which mainly includes the bearing seat body, the top surface of the bearing seat body is an arc surface, the arc surface is provided with a water cooling groove, and the outer side of the water cooling groove is sealed and welded with a stainless steel cover plate; the bearing seat body; The bott...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a bearing seat for a four-row tapered roller bearing with a new structure for a rolling mill, to solve the problem that the upper and lower parts of the bearing seat are often connected and fixed by bolts when the existing similar bearing seat is in use. The staff need to hold a wrench to disassemble and assemble, which is cumbersome, and the heat dissipation performance is poor. It is difficult to release the heat generated by the bearing rotation in time. Excessive temperature will easily shorten the life of the internal lubricating oil and affect the lubrication effect of the bearing.
