1, to understand the overall and joining dimensions of the shifting drive bearing.
2, shifting drive bearing horizontal placement or vertical or inclined place. Pros and cons can be rotated. Both input and output power (that is, slow down or growth).
3, shifting drive bearing regardless of how it was installed, with couplings all dimensions meet the requirements.
Recommended:
D inner hole and shaft meet by H7/h6;
Do ring top pin in hole by H7/r6 in conjunction with transmission;
D cooperate with shell in H8/h7 in the outer ring;
Hole on the drive and output shafts combined with clearance fit, clearance of 0.2~0.5mm.
4, shifting drive bearing axial position: any one of the three laps after the axial positioning ring, b is no longer axial positioning.
5, rotation direction; outer rings and inner rings are flat key position. Circle is used in driving position.
6, shifting drive bearing diameter up to withstand small forces, but not stand heavy workload.
7, transmission ratio, is the first installation of the transmission ratio. If using other installation methods, you should calculate the gear ratio.
8, at the rated speed (1500rpm), depending on transmission ratio and power required (Kw) select the shifting drive bearing model.
9, when according to torque, and accordingly select the model.
10, reducer model selected should be consistent with the model of the shifting drive bearing.
