Problems solved by technology

If the bearing clearance is too large and the bearing is too loose, shaking will occur during work, which will affect the precision of the equipment
If the bearing clearance is too small, the bearings will be too tight, the bearings will squeeze each other, and the wear will be serious, which will affect the service life.

Abstract

The invention provides a bearing clearance pre-tightening method applied to the technical field of boring and milling machine parts, and further relates to a bearing structure. A first bearing pack (1), a mounting sleeve (2), an outer spacer bush (3), a second bearing pack (4) and an inner spacer bush (9) of the bearing structure sleeve the mounting sleeve (2), a bearing of the first bearing pack(1) is attached to a limit boss (12) of the mounting sleeve (2), the inner spacer bush (9) is located on the inner ring of the outer spacer bush (3), a clamp nut (6) is screwed up on a threaded portion (5) of the mounting sleeve (2), and the thickness size of the outer spacer bush (3) is equal to that of the inner spacer bush (9). According to the bearing clearance pre-tightening method and the bearing structure provided by the invention, bearing clearances can be effectively controlled during bearing mounting, bearings are made to work in a satisfactory working state, and the service lives ofthe bearings are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of milling and boring machine parts, and more specifically relates to a bearing clearance pre-tightening method, and the invention also relates to a bearing structure. Background technique [0002] Bearings are an essential part of milling and boring machine equipment. When installing bearings on a milling and boring machine, especially when installing multiple sets of bearings, it is necessary to control the bearing clearance so that the bearing clearance is in an ideal state. If the bearing clearance is too large and the bearing is too loose, shaking will occur during work, which will affect the precision of the equipment. If the bearing clearance is too small, the bearings will be too tight, the bearings will squeeze each other, and the wear will be serious, which will affect the service life. Therefore, the bearing clearance adjustment is extremely important. Contents of the invention [0003] The t...
