Angular contact bearing installation method

The installation of the high speed precision angular contact ball bearing high speed precision angular contact ball bearing, mainly used for high speed rotating load lighter, bearings and high precision, high speed, low temperature rise, low vibration and service life. Often for high speed motorized spindle bearing parts installed in pairs, is the key to the high-speed motorized spindle surface grinding machine fittings. The main technical indicators: 1. Bearing precision index: more than GB / 307. 1 - 2 94 P4 level precision. High-speed performance indicators: dmN value of 1. 3 to 1. 8x 106 /min 3. The service life ( On average) :> 1500 h high-speed precision angular contact ball bearing service life had a lot to do with the installation, should pay attention to the following: 1. Bearing installation should be clean, clean the room, the bearing should be carefully selected, bearing with baffle passes through grinding, and in keeping the baffle on inner and outer contour under the premise of baffle parallelism should be controlled below 1 um. 2. Bearing should be cleaned before installed and when cleaning inner ring ramp up, flexible hand induction, no stagnation, air-dried, into the specified amount oil, if oil mist lubricating oil should be in a small amount of oil mist; 3. Bearing installation should use specialized tools, force uniform, do not knock; 4. Bearing deposit should be clean and ventilated, non-corrosive gas, relative humidity is not more than 65%, long-term storage should be rust on a regular basis. With diagonal contact ball bearing load capacity calculation formula is: 1, face to face with the back to back or matching the basic dynamic load rating of bearing C = 1. Series 62 x C single bearing 2, configure the basic dynamic load rating of bearing C = 2 x C single bearing basic static load rating C0 = 2 x C0 single bearing fatigue load limit Pu = 2 x Pu single bearing angular contact ball bearings and tapered roller bearings are able to bear a large axial force bearing, upside the can't afford to bear the effect of axial force. How is the dress? Angular contact ball bearing ring and the contact Angle between the two, the standard of the contact Angle is 15 ° 40 °, 30 °, and the larger the contact Angle of the axial load capacity is, the greater the contact Angle is smaller, the more conducive to high-speed single bearing can bear radial load and one-way axial load axial force when installation should be from outer thin to thick outer side direction of the force!
