Bearing drawings: outer spherical bearing G stand for

Dyed point distribution, demanding ° - in the center of the bearing - every square centimeter in ° Angle Points so far, shoulds not be too little or too much; Otherwise, need crapping, after shaving with a white cloth dipped in alcohol clean tile face and neck, repeat the above research method, make the bearing shell dyed point scraping the thinner, the more more more, until it meets the requirements. For rolling bearing clearance shall not adjust, because of the radial clearance as defined by the standard in manufacturing has been good, can't adjust, such loading on the diameter of axle bearing or bearing hole, after the actual radial clearance is called assembly radial clearance, assembly time to assemble the size of the radial clearance is right to make necessary work in the operation of radial clearance, in order to protect the bearing flexible rotation. Improper installation, About %) Use brute force: when installation, directly with a hammer percussion bearing to bearing damage, is the main cause of deformation; Installation does not reach the designated position, install a deviation or failure to bearing, bearing clearance is too small. You can use a little oil, put into, tool splint convex shoulder must resist inner ring, adjust the tie rod nuts make weeks forcibly even, then turn out screw pull out bearing. Shaft under the conditions of low speed rotation daub polymer materials, note: grinding, grinding liquid cooling must be used; Shaft end parts repair materials must be chamfering processing. What bearing grease is not in conformity with the requirements or contaminated lubricating grease choose not appropriate, not easy to form homogeneous lubricating oil film, unable to reduce the bearing internal friction and wear, lubrication, bearing temperature rise. The limits of synthetic lubricant temperature is much higher than oil, the characteristics of two phase flow field of heating and temperature distribution of bearing has a decisive influence, has a great influence on the performance and service life of the bearing. Traditional detection, & amp; emsp; & emsp; The author understands, high bearing temperature is crusher common problem, is also a great failure. Thickener is a mixture of sodium calcium soap and soap, drop point ~ ℃, penetration to mm, weak water resistance in calcium base grease, allow the water vapour or work in damp environment and working temperature for ~ ℃, not suitable for low temperature. Has carried on the induction, and share with you, the size of its force in order to protect the transport and the starting, bearing is not due to the backward from the shaft extension end to the load for axial force and the damage degree. Metal material concession sex difference, the longer it is easy to cause micro fit clearance, if not found in time and take measures, will cause the micro gap widening, directly run bearing inner ring, bearing damage. Reason: the impact of the host load is too large, large amount of spindle and the bearing fit interference; Also have larger stripping friction causes the crack; When installation precision is bad; Improper use, With copper hammer, card into the big) Friction and crack.
