What are the maintenance skills of self aligning ball bearing friction?
Clicks:15485 Date:11-27
Self aligning ball bearing is matched with the static ring bearing and rotating the rings are stationary and part of the mount (usually bearing) and rotating part (usually axis) with consolidation, in order to achieve the load transfer and limited movement system relative to the stationary system of basic tasks in rotating state.
In the shaft and bearing seat, deep groove ball bearing requires radial, axial and tangent direction in three directions to fix its position. The radial and tangential position through the tight fit of the self aligning ball bearing rings mining, axial position only in a few cases the use of tight fit; deep groove ball bearings with axial spacing parts, such as cover and ring to limit the axial position in the clearance range.
When self aligning ball bearing shaft is directly contacted with the Bush, the adhesion and boundary lubrication performance can be prevented. The material factors affecting the friction compatibility of friction pairs are:
(1) the degree of difficulty in forming alloy by metallurgical materials.
(2) the affinity between materials and lubricants.
(3) friction coefficient of auxiliary materials under non lubrication condition.
(4) microstructure of materials.
(5) thermal conductivity of materials.
(6) the size of the surface energy and the characteristics of the oxide film.
The high pressure oil is injected into the bearing by the oil pump, and the oil in the bearing is injected into the oil groove at the other end of the bearing. In the bearings rotate at high speed, roller and cage to very high rotation speed of the surrounding air to form air lubrication method is difficult to use lubricating oil to the bearings, then we must use the method of high pressure jet lubricating oil spray to self aligning ball bearing, nozzle position should be placed between the inner ring and the cage center.
