The micro - Bearing installation principle

Miniature bearing installation option bearing installation method is very important, according to the situation, choose suitable correct method. Bearing installation is to pay attention to at the same time, if the installation is undeserved, can affect the precision of the bearing, the life and performance. Therefore, please fully study the installation of the bearings, earnest reference bearing installation manual, today by admin tell everyone about the miniature bearing installation principle! Before the installation note 1) Bearing: due to the bearing through antirust processing and packaging, so do not open the packing before installation. In addition, the coating on bearing anti-rust oil has good lubrication performance, for general purpose bearing or bearing grease filling, can not directly use cleaning. But for the instrument bearing or bearing for high-speed rotation, the application of clean cleaning oil washed away anti-rust oil, when the bearing is easy to rust, not a long time. 2) Axis and shell of inspection: the bearing and the shell cleaning, confirm no scar or mechanical processing of burr. Shell has absolutely not YouYan grinding agent ( SiC and Al2O3, etc. ) Sand, scraps, etc. Next inspection shaft and shell size, shape and machining quality are consistent with those drawings. Before install bearing, in the inspection of shaft and the shell of the mating surface coating machine oil. Bearing the installation method of bearing installation method for bearing type and matching conditions are different. Due to the more commonly as the axis of rotation, so the inner ring and outer ring can be divided into: don't use interference fit and clearance fit, the outer ring rotates, the outer ring USES the interference fit. ( 1) Pressure into the installation: the installation in general use press, also can use a bolt and nut, when forced to use hammer into the pack. ( 2) Heat installation: heat the bearing in oil so that it has expanded again after installed on the shaft of the hot set method can avoid unnecessary force, the bearing in a short time, complete the installation.
