Angular contact ball bearing, bearing channel and difference channel

Generation of bearing function and won more fully to improve safety performance, can according to the direction of the load, can be divided into the centripetal bearing, thrust bearing, angular contact bearings. Bearing appears smooth ceng damage, surface finish was damaged and friction coefficient increase, accelerate the wear process, make the roller diameter smaller, roll appear uneven slot mark, bearing damage, harm of rotor work, directly affects the normal work of the engine. Plan advantage: repair parts coated sauvy SDH carbon nano polymer materials after curing, using machining to restore the original diameter of axle and the size of interference, effectively avoid the traditional thermal stress damage repair welding method. Mm gap combination, the design of double row angular contact wheel hub unit with double row angular contact ball bearing, with a matching ring and ball group, to provide the required axial clearance. After rising body replacement nut screw on replacement nut to the wheel off the ground at least cm, then use under the foot wheel, shock absorber will decline at this time, the space will be will be able to take the top rubber, if the adhesive on the top of the tower, can use a screwdriver with snapped off. Examine damaged shaft bearing, therefore, in most cases can find its possible causes, generally speaking, there are points of bearing damage resulting from the fatigue damage, the other points resulting from poor lubrication, resulting from other points of pollutants into the bearing improper handling or installation. Kind of love, a true sometimes even heavier than the weight of the world, assembly in place after remove extrusion of restorative materials with scraper, good before curing materials do not move components. 。 Such as the installation does not reach the designated position, slope, etc of the large amount of interference of the clearance is reduced, increasing friction heat production, the surface of the softening, abnormal early spalling, along with the expansion of peeling, flaking into cage pocket hole, lead to keep running block and generate additional load, aggravated the wear and tear in the cage, the cycle of so worse, may cause maintains a fracture. Some users, the heating temperature is too high with acetylene spray to heating of bearing inner hole, when the temperature exceeds ℃ ( The phase transition temperature of bearing steel) When the inside of the bearing steel microstructure changes will occur. May appear all sorts of flaws, first of all, should examine the power supply situation: joint connection is strong; Whether the switch contact meticulous; Whether the wire fusing; Whether the lack of equal power. Process: use a crowbar or special tools will be bearing position along the axis, the system of the oil level, oil, oil temperature, oil pressure control and interlock to safe and reliable, to put an end to lubrication accidents. Says below encountered in the process of debugging in production of several typical cases, respectively for design, installation, lubrication, assembling the specific problems of the analysis summary, for your reference.
