Combined type labyrinth sealing bearing

Abstract

The invention discloses a combined type labyrinth sealing bearing. The combined type labyrinth sealing bearing comprises a mounting alignment end, a labyrinth buckle sealing shaft shell, a buckle cover and a ball, wherein the mounting alignment end is embedded into the labyrinth buckle sealing shaft shell and is coaxial with the labyrinth buckle sealing shaft shell; the labyrinth buckle sealing shaft shell comprises a magnetic field pushing device, a magnetic field end to be pushed, a stress extruding body, stopping buckles to be pushed, a protection shell, a buckle device, a ball mounting groove, a friction groove, a movable friction rod, a stress extruding triggering device and a magnetic field end to be started; the combined type labyrinth sealing bearing is characterized in that the two stopping buckles to be pushed are arranged; the buckle device penetrates through the inner part of the protection shell and is welded with the protection shell; the ball mounting groove is formed ina lateral side of the protection shell; the movable friction rod and the friction groove are located on the same axis. Compared with the prior art, parts can be separately placed; when the parts needto be mounted, the parts are stacked together, so that equipment in the combined type labyrinth sealing bearing pushes the buckles to clamp at the maximum limit, a loosening condition is reduced to the minimum, and the equipment can be assembled separately.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a combined labyrinth seal bearing. Background technique [0002] Senkimir rolling mill bearings are high-end rolling mill equipment in the field of steel cold rolling. They are mainly responsible for the rolling of high-precision silicon steel and stainless steel sheets. The quality of the bearings directly affects the running stability of the rolling mill. The bearings are mainly divided into open and sealed. For a long time, the application effect of domestic sealed structure bearings has been unsatisfactory, mainly due to problems such as poor sealing contact, insufficient interference, slipping and loosening, and unstable pressure, which directly affect the service life and life of the bearings, resulting in domestic Senkimir rolling mills. The bearing market has always been monopolized by imported bearings. The early form of linear motion bearings was to place a row of wooden poles u...

Problems solved by technology

[0003] For the current bearing, its shape is limited during its production process, and it is already a whole. It is difficult to disassemble it or better assemble it, which is easy to cause looseness and unevenness of the bearing. stable
