Fag bearing type: diy solar magnetic suspension bearing to want what spare parts

Punching cage J - — Stamping steel cage, the bearing under the ABEC system called precision bearing, the higher the number from the number, precision grade, the higher bearing manufacturing. Using carefully measuring feeler gage to wear such as position, according to the wear condition to determine the repair plan; According to the wear and tear on the axial and radial auxiliary method of the axial and radial, big limit to ensure alignment in order to protect the use after repair effect; Test and bearing, at room temperature using the standard size of bearing inner ring, by adding points in order to meet the requirements of bearing assembly; With gas welding baked into grease on the surface of the worn parts, carbide to Mars, grease. Causes of the wear between: operate at a high speed and the constant axial load under point contact ball bearing, the ball will generate dynamic load centrifugal force and gyroscopic moment of inertia of the large centrifugal force role Yu Gangqiu, always make the ball to the outer ring, cause the outer contact Angle decreases, and the inner ring of contact Angle increases, with the increase of speed within one and a half circle by partial discharge to completely uninstall, bearing should be changed from point contact to two-point contact right now, if the bearing is still not out of point contact at this time, due to the effect of gyro moment, steel ball will be half a circle in the load of the severe sliding channel, the cause of bearing parts abrasion or wear. Bearing is screw drivers of precision parts, a little damage can cause failure of the whole screw drivers, so we should pay attention to daily use, the screw drivers for maintenance, and keep its normal work, and don't overload the reasonable lubrication is confirmed reliable operation rolling bearings and the life of the key factors. When filling Angle exceeds °, the device will compare difficult, as under RPM speed of the motor mostly adopts CM clearance, such as high temperature and high speed motor, require the use of relatively large clearance. With oil pool heater motor, if the motor used in the winter in the north, in h before starting the heater must be open, and time, pay attention to the oil temperature oil pool, to ensure the oil temperature is less than t. Overloading, two sides with dust cover or seal bearing, assembly don't need to clean; Coated with rust bearing lubrication and grease, when assembly, also don't need to clean. Amorphous layer organization grinding the instantaneous high temperature makes the workpiece surface reach a molten state, molten metal molecular flow is evenly coated to the work surface, and the matrix metal cooling at breakneck speed, formed a very thin layer of amorphous tissue layers. But as a result of the expansion coefficient of bearing coat than bear the bearing chamber of cast iron parts - — Or bearing sets of large and bearing a coat of temperature is higher, so the original bearing coat at room temperature can slide along the axial in bearing chamber, but bearing during operation after heated also not necessarily can string move, that is using two ball bearings bearing life is short, the main reason for the fever. Shell hole tolerance zone in order to satisfy the use requirement, and switch to Kmm, mm; Delta plain surface average diameter deviation on Dmp = mm, delta under the Dmp = - 。 Gear box is very widely used in industry, and as a result of the wear of gear box bearing chamber gear box can not continue to work normally, the common problems of in order to let everyone have a good understanding, to make an introduction to the reasons of gear box bearing chamber wear, and to make repair case, hope to be of help. At the same time of help enterprises to improve equipment management means, can limit production line for downtime, production and the economic benefits of losses, MESYS software is a professional mechanical engineering calculation software, the bearings, shaft and the shaft can be calculated analysis.
