Dust-proof and easy-to-remove bearings for high-speed precision CNC machine tools

Abstract

The invention discloses a dustproof and convenient-to-dismount bearing for a high-speed precision numerical control machine tool. The dustproof and convenient-to-dismount bearing can solve the problems that when a bearing for a traditional high-speed precision numerical control machine tool is used, a gap exists between an inner shaft inside the bearing and an outer ring outside the bearing when the bearing is in use, so that dust enters easily, the rotation accuracy of the bearing is affected after long-term use, and the service life of the bearing is shortened; and moreover, because the bearing is extremely difficult to dismantle, when some part in the bearing is damaged, the bearing cannot be dismantled and have to be replaced as a whole. The bearing comprises a bearing block and a bearing main body fixedly arranged in the bearing block. Fixing side grooves of concave structures are formed in the outer walls of the two sides of the bearing block. An arc-shaped top with an arc-shapedstructure is arranged at the top of the bearing block. A top small hydraulic pump is arranged inside the arc-shaped top. A bolt connected with the outer wall of the bearing main body is arranged on the arc-shaped top in a penetrating mode. A screw cap is connected to the bolt in a screwed mode.

Description

technical field [0001] The invention relates to a bearing, in particular to a dust-proof and easy-to-remove bearing for a high-speed precision numerical control machine tool. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The application range of bearings is very wide, including high-speed precision CNC Machine tools, while high-speed precision CNC machine tools refer to high-speed, precision CNC lathes, turning centers, and compound processing machine tools with more than four axes linkage, mainly meeting the needs of aerospace, aviation, instruments, meters, electronic information and bioengineering industries. Bearing applications High-speed precision CNC machine tools require higher precision and performance. [0003] However, the existing high-speed precision CNC machine to...

Problems solved by technology

[0004] The purpose of the present invention is to provide a dust-proof and easy to disassemble and replace bearing for high-speed precision CNC machine tools, which can solve the problem of traditional high-speed precision CNC machine tool bearings when they are in use. There is a gap between the outer rings, so that dust is easy to enter. Long-term use will not only affect the rotation accuracy of the bearing, but also greatly reduce the service life of the bearing, and because the bearing is extremely difficult to disassemble, when a part inside the bearing is damaged The problem that it cannot be disassembled but can only be replaced as a whole
