For cone bearing: 6206 bearing inner ring diameter

Mold casting manufacturing cage puts engineering plastic vacuum drying of granular material barrel, a resistance wire heating melt into a liquid state, with the help of a plunger or mobile screw pressurizing, half liquid raw materials from nozzle injection molding into forming mould, after heat preservation, cooling to obtain required cage. If the radial force of two fulcrum, is often chosen as swimming end shaft extension end, in order to prevent the nut contact with bearing cage, should add spacer between the nut and bearing. Is put forward by the special TH check reducer high speed shaft bearing oil company, always can't see exactly how much oil can be added to go in the high-speed bearing, such as complete demolition of tubing with high-pressure air purging, blocked two thin cotton rope inside discovery! In addition, TH company in the process of replacement of reducer bearing, also found that the bearing eccentric set oil hole is too thin, Eccentric set oil hole can than bearing its own oil hole diameter big specification) , so will be the oil hole reaming processing. The north cold area, the surface of the axle box heat faster, if you have any individual with car axle box above the top temperature is higher than the temperature of baidu, is not normal phenomenon, should find out the reason. Spectrum is very single frequency doubling, only a lot of this kind of accident, also accumulated some practical skills, is this kind of bearing in the early part of the device after operation, monitoring the status of vibration, spectrum analysis was carried on. Load due to the size of the grease cone into the degree of relationship to use when can withstand the load, load should choose cone into the large degree of small, Consistency is bigger) The grease; If is under heavy load and impact load, should choose to contain grease of extreme pressure additives such as grease containing molybdenum sulfide. Bearing clearance, after appropriate operating temperature ℃ or so, normal, XC company cement mill reducer coupling itself processing error is too great, cause of bad, motor bearing high temperature, large equipment vibration. If in some special occasions to use higher speed bearings, such as used in high-speed cutting machine tools and precision machining of high speed rotation axis ChengHai can use ceramic bearings, electrical, magnetic bearings and other special bearings, will contact the professional manufacturers. Lubrication way six selection principles after the above analysis, for the advantages and disadvantages of all kinds of lubrication method has carried on the comprehensive evaluation, so in terms of the bearing lubrication mode selection, can according to actual operation condition to choose the suitable way, main principles can be summed up in the following points: if the bearing running speed and temperature indicators are reasonable, then you can choice the way of the grease. Vertical motor bearing configuration when the vertical motor to drag the cylinder in the petrochemical system with pump, because of the multi-stage cylinder pump in the starting moment of the axial force upward, plus freight on request, and to bring damage to bearing rotor thermal expansion, vertical tube with pump motor ( All are very or extremely) Motor, bearing should choose to install two single row angular contact ball bearings, the bearings with cylindrical bearings, is to choose light series is advisable. Bearing and shaft test good method is through the vibration problems whether bearing and shaft, bearing and shaft also how long does it take to be able to run, it is need to maintenance personnel. 设置- - - The Set - RightTM method Right to use the probability method and control the dimensional tolerance of related parts to ensure that all assembly assembly.
