    Design Considerations of variable speed bearing applications
    1, the shape of the variable speed drive bearing and connection size reference special bearings
    2, variable speed drive bearing level of placement, can also be vertical or tilted placement. Can be positive and negative rotation. Can be positive and negative input and output power (ie, deceleration or growth).
    Variable speed drive bearing regardless of which installation method, coupled to have the size to meet the requirements.
    Recommended:
    Inner hole d and shaft with the press H7/h6;
    In the ring, pin holes do drive with the press H7/r6;
    The outer ring D and the shell with H8/h7;
    The transmission output shaft hole with clearance fit clearance volume of 0.2 ~ 0.5mm. special bearing
    4, the axial positioning of the variable speed drive bearing: a circle three tim es any axial location, the other two axes do not need to axial position.
    5, rotational orientation; outer ring and inner ring are the positioning of the flat key. In the circle drive positioning
    6, variable speed drive bearings in the radial direction can be subjected to a smaller force, as shown in Figure 5, but should not bear a greater workload.
    7, the transmission ratio, are according to the first installation of the transmission ratio. If using other installation methods, the transmission ratio should be calculated according to Table 1.
    8, at the rated speed (1500rpm) under, according to the transmission ratio and the required power (Kw) of Table 2 to select the variable speed drive bearing models.
    When working torque, according to selected models in Table 3.
    10, model selection and variable s peed transmission shaft of the reducer model. bearing catalogue
