Precautions when using variable speed FAG bearings

Use variable speed FAG bearings should pay attention to:

1. Understand the shape and connection dimensions of the variable speed drive FAG bearing.

2. The variable speed transmission FAG bearing can be placed horizontally or vertically or tilted. Can be rotated forward and backward. Positive and negative input and output power (ie deceleration or speed increase).

3, variable speed transmission FAG bearing regardless of the installation method, and its couplings have size matching requirements.

Recommended:

The inner ring hole d and the shaft are matched by H7/h6;

The pin hole do of the middle ring and the transmission are matched by H7/r6;

The outer ring D and the housing are matched by H8/h7;

The transmission and the hole on the output shaft are matched by a clearance fit, and the gap is 0.2~0.5mm.

4. Axial positioning of variable speed drive FAG bearing: After any three turns of the ring are axially positioned, the other two axes do not need to be axially positioned.

5. Positioning in the direction of rotation; both the outer ring and the inner ring are flat key positions. The middle circle is positioned using the drive.

6. Variable speed transmission FAG bearings can withstand small external forces in the radial direction, but should not withstand large working loads.

7. Transmission ratio is the transmission ratio according to the first installation method. If other installation methods are used, the gear ratio should be calculated.

8. At the rated speed (1500 rpm), select the variable speed drive FAG bearing model according to the transmission ratio and the required power (Kw).

9. When based on the working torque, the model number should be selected accordingly.

10. The selection of the reducer model should be consistent with the model of the variable speed drive FAG bearing.
