Non-standard bearings manufacturer to install and remove the matters needing attention

Non-standard bearings manufacturer to install and remove the note source: bearing | last updated: - 2020 08 - 04 non-standard bearings manufacturer to install and remove the matters needing attention in the hope that before the installation, just open the bearing packing. General grease lubrication, cleaning, not directly fill grease. Lubricating oil, ordinary also don't have to be clean, but, instrument using or high speed bearings, etc. , to be washed with clean oil, remove rust inhibitor) on the bearing. Remove the rust inhibitor of bearing, easy to rust, so cannot be placed. Also, has the bearing grease sealed, not directly use cleaning. Bearing installation method, owing to the different bearing structure, with other conditions. In general, as more as the axis of rotation, so the inner circle need interference fit. Cylindrical hole bearing, multi-purpose press pressure into, or multi-purpose hot charging method. Taper hole, installed directly on the taper shaft, or use the socket installation. When installed on the shell, clearance fit more commonly, outer ring have surplus quantity, usually use the pressure into the press and or have shrink fit method of cooling after installation. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of bearing. So, need a good rust prevention measures. The installation of the bearings generally needed a bearing heater and other professional tools. Non-standard bearing running noise for a long time to do non-standard bearing raceway sound and sound way to control the raceway ring raceway is bearing at the time of operation, the bearing roller rolling on raceway and the sound of continuous features is slippery, the sound is all the rolling bearing will produce the basic sound. Some of the most common bearing noise is rolling way voice and other sound mixing. Race also have different, for example, the ball bearing raceway acoustic sound of raceway is irregular, she has to frequency above 1000 hz, and its main frequency and other bearing different is that it is not changes with speed, but its total sound pressure level is increased with the speeding up of the rotational speed. Some bearing raceway sound particularly big, the sound pressure level and its race viscosity range is, the smaller is the greater the viscosity of raceway sound; And some of the raceway small bearings, the raceway sound pressure level and viscosity is proportional, the greater the pressure level, that is, the more viscous loud. Raceway sound changes and the rigidity of the bearing has a relationship, and the stiffness of the bearing and the raceway of sound pressure level is, the rigidity of the bearing, the greater the raceway of the total sound pressure level will be lower. Also have relationship with radial clearance, radial clearance and the raceway of sound pressure level and the main frequency is inversely proportional, the smaller the radial clearance, the greater the sound pressure level and the main frequency. Looked at these, for sound control method is also a little clue, we can choose waviness small bearings, this will effectively reduce the noise, you should be careful in terms of use. Raceway of sound a big impact for the overall mechanical noise, raceway noise reduction can effectively reduce the mechanical noise.
