Bearing outside diameter tolerance: rolling bearing apart the zha assembly

Cause poor lubrication bearing damage is also common situation, here we mainly analysis the different levels of bad lubrication bearing damage, good let everyone to adopt the reasonable solution depending on the situation. Sliding and rotation, and other important parts clean, thin oil film layer; F, but its shortcomings are obvious: first of all, for a large equipment such as fan axis wear problem can't be online repair. Thermal shock is when the temperature gradient inside the material will lead to the expansion of the different, this can lead to internal stress, the pressure can exceed the material form the strength of the crack. The cause of the problem analysis: through the study found that loud noises in the process of tool change occurred in the manipulator slotting tool stage, the reason is that the spindle must stop location error problem and spindle tool change reference point drift problems. Bearing for normal operation of the sound, if a sharp hissing sound, make sound, and other irregular often said bearing undesirable swing, reason: the raceway surface stripping, countermeasures: change the bearing, the irregular noise reasons: clearance is too large, countermeasures: research cooperation and bearing clearance, load changes. Printing rubber roller maintenance in offset printing technology is the key of water and ink balance control, road and ink balance by rubber roller, ink roller this key components, its quality can be directly impact on the quality of the product. McPherson suspension design let many models have very small before hanging, save the design of very large space, so you will only see wheelbase only around eight meters SMART can still adopt the design of the suspension. mm； Face round beating requirements: shoulder, no matter which side out of the question, product already processing it, the casting machining allowance for little or no allowance. Consider using the outer seal; Gully erosion symptoms: cover raceway for the most part or whole raceway circumferential axial parallel brown nicks; Reason: last by alternating current or direct current (dc); Even low current; Solution: by the methods of grounding insulation or prevent current through the bearing; Use the electric insulation bearing; Excess load symptoms: serious roller grinding crack; Overheating; The spread of fatigue area ( Spallation) ； Reason: the bearing of excess load; Solution: reduce the load; Redesign. Coiler reducer bearing chamber wear problem solution sauvy carbon nano polymer repair technology is the use of carbon nanotubes unique mechanical properties of polymer materials and the wear-resisting performance of repair process online repair bearing wear problem. Bearing examination should focus on what & amp; #; Bearing the quality first, check whether there is grease metamorphism, agglomerate, impurities such as adverse situation, this is the important basis of reason judge bearing damage. To prevent rusting of the bearings bearing directly with the hand, should fully wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust.
