How to use variable speed bearing

How to use the variable speed bearing

1. Consider the shape and connection dimension of variable speed drive bearing

2. The variable speed drive bearing can be placed horizontally, vertically or obliquely. It can rotate forward and backward. The output power can be input in both positive and negative directions (i.e. deceleration or acceleration)

3. No matter what installation method is adopted, the variable speed drive bearing has dimensional matching requirements with its connecting parts

recommended: the fit between inner ring hole D and shaft is h7/h6; The fit between the pin hole do on the middle ring and the transmission shall be h7/r6; The fit between outer ring D and housing is h8/h7; Clearance fit is adopted for the matching between the transmission and the upper hole of the output shaft, and the clearance is 0.2~0.5mm.

4. Axial positioning of variable speed drive bearing: after any one of the three additional simple accessory rings is axially positioned, the other two shafts do not need to be axially positioned

5. Orientation of rotation direction; The outer ring and inner ring are positioned by flat keys. The middle ring is positioned by transmission

6. The variable speed drive bearing can bear small external force in the radial direction, but should not bear large working load

7. Transmission ratio is the transmission ratio of the first installation mode. If other installation methods of the corresponding dial and pendulum are adopted, the transmission ratio shall be calculated

8. Under the rated speed (1500rpm), the variable speed drive bearing model is selected according to the plate spring will also be re pressurized to the specified pressure test pressure value 0, V90 and XC60 dynamic ratio and required power (kw) in S60, S90 and V6

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

10. The selection of reducer model is consistent with that of variable speed drive bearing
