Installation skills of angular contact ball bearings

High speed precision angular contact ball bearings are mainly used in light load high speed rotating occasions, requiring high precision, high speed, low temperature rise and low vibration and a certain service life. The supporting components of high-speed motorized spindle are used in pairs, which are the key components of high speed motorized spindle for internal surface grinding machine.

Installation form

Angular contact ball bearings and easy automation selection Daquan can provide selection, installation form of angular contact ball bearings, a series of face to face and back to back, three. (two back-to-back wide end bearing relative) installation, bearing contact angle line along the axis of rotation diffusion direction, bearing angle can increase the radial and axial rigidity, maximum deformation resistance; face to face (two relatively narrow end bearing) installation, bearing contact angle of the rotary axis line towards the direction of its convergence. Bearing angle less rigidity. Because of the inner ring of the bearing outer ring out, when pressing the outer ring two bearing together, the original gap ring is eliminated, can increase the bearing preload; tandem arrangement (two wide end bearing in one direction) when installing the bearing contact angle and parallel lines in the same direction, the two share the same bearing the direction of the work load. However, in order to ensure the axial stability of the installation, two pairs of bearings arranged in series must be installed opposite to the ends of the shaft in order to ensure the axial stability of the installation.

Main technical indexes:

1. bearing accuracy index: more than GB/307.1-94 P4 accuracy

2. high speed performance index: dmN value 1.3~1.8x 106 /min

3. service life (average): >1500 H

The service life of high speed precision angular contact ball bearing has a great relationship with installation, and the following items should be paid attention to

1. bearings should be installed in dust-free, clean room, bearing should be carefully selected, bearing ring to be grinding, in maintaining the inner and outer ring ring height, the ring parallel degree should be controlled below 1um;

2. before the installation of bearings should be cleaned, cleaning inner ring slope upward, hand induction flexible, no sense of stagnation, after drying, into the specified amount of grease, such as oil mist lubrication should be placed in a small amount of oil mist oil;

3. bearing installation should use special tools, uniform force, no beat;

4. bearing storage should be clean and ventilated, no corrosive gas, relative humidity is not more than 65%, long-term storage should be regularly antirust.
