Rolling bearings: how to look out of the bearing changed good

This kind of bearings mainly take radial load, the bear radial load at the same time, can also carry a small amount of axial load, usually is not used for pure under axial load, such as pure axial load, only column of steel ball bearing roller, spherical roller bearing has two columns is mainly used to bear radial load, but also can withstand the direction axial load. Pure axial load, thrust bearing, optional motor using bearing is a bearing parts, can guide the axis of rotation, also can withstand the above the shaft parts. Countermeasures: change meets the design requirements of aperture bearing box, if that is the catastrophic damage, LTD bearing to determine the root cause of the problem, because may be outside lubrication factor. Please note; Linear bearing is not suitable for plug repeatedly, ten, rated life life life can according to the basic dynamic load rating and imposed on the linear bearing load. Sauvy engineer for this problem, quickly carried out technical discussion, remove the reducer in the enterprise in time, sauvy engineer overnight work overtime according to wear trunnion sizes customized processing 'sauvy tooling', at noon and in the day to arrive at the enterprise site equipment. N— — Outer ring with locking slot on the bearing, and ten thrust cylindrical roller bearings by a circle of ring shaped raceway ( Axial circle, seat) With cylindrical roller and cage components. Overloading when low speed, thrust roller bearings, with small axial clearance to withstand the thrust load, make close axial lead of the roll, and can withstand axial load force. The quick method to solve the problem of bearing wear traditional methods like machining after welding to repair, and surfacing can make parts surface at high temperature, causing parts deformation or cracks, obtained by machining size cause downtime greatly extended. It is more hard than stainless steel, so it can last longer, the higher the working temperature, allowing the tangent speed to reduce accordingly, when work ° C temperature is reached, the tangent velocity down ~ %. Rockwell hardness of steel ball bearing steel ball hardness is carbon steel ball, stainless steel balls, bearing steel ball of the commonly used steel ball in the high hardness, HRC above, because good abrasion resistance, high precision bearing steel balls are widely used in bearing assembly, low accuracy of bearing steel ball is mainly used for polishing, grinding, etc. Cause of pre-load; Caused by roll wear and ring tilt skew roller; Cylindrical roller bearing axial load is too high; The matching of the square; On the surface of the axial pre-load excessive; Solution: to improve the lubrication ( Increase the viscosity, EP additives and quantity) ； Ensure the correct bearing adjustment; Symptoms: reverse loading ball appears on the outside the raceway edge rolling on gully erosion caused by; Reason: angular contact ball bearing is designed to only in the axial direction of the force; By reverse load. For high precision rotary spindle, the commonly used method is in the liner between the bearing inner and outer ring, inner casing can be slightly oblique, then with both hands thumb and index finger two bearing all the clearance, the other with only middle finger into the bearing hole, strike had partial lining set, check whether the resistance is similar to the bushing.
