1, the variable speed drive bearing reference to the shape and size of connection
2, variable speed drive bearing placed horizontally, vertically or tilt can be placed. Can be both positive and negative rotation. Can be both positive and negative input and output power (ie, reduction or growth rate).
3, variable speed is drive bearing regardless of installation, its parts are connected with the size requirements.
Recommended:
Inner hole d and shaft by H7/h6;
Do in the ring with drive pin hole with the press H7/r6;
D and with the outer shell by H8/h7;
Transmission and output shaft hole with the use of space cooperation, space volume of 0.2 ~ 0.5mm.
4, variable speed drive bearing axial positioning: the circle three times for any axial location, the other two axes is no longer axial position.
5, the rotation direction of orientation; outer and inner rings are flat key position. The circle is to use the drive position.
6, the variable speed drive bearing in the radial force on affordable small, as shown in Figure 5, but should not bear a greater workload.
7, the transmission ratio, are installed according to the first mode of the transmission ratio. If you use other installation methods, should be calculated according to Table 1, the transmission ratio.
8, at rated speed (1500rpm), according to the transmission ratio and the required power (KW) Table 2 select variable speed drive bearing models.
9, when the work is based on torque, the selected models in Table 3.
10, the gear selection is variable speed drive models bearing the same model.
