Variable speed bearing design considerations of the application of 1, the appearance of variable speed drive bearing and the connecting size reference 2, variable speed drive bearing horizontal placement, can also be placed vertical or inclined.
Can be positive and negative rotation.
Can be positive and negative input and output power (
The reduction or growth)
。
3, variable speed drive bearing no matter adopt what kind of installation method, and its connection are size requirements.
Recommended use: d inner circle hole and shaft with the H7 / h6;
Circle the pin hole on the do cooperate with transmission of the H7 / r6;
With the outer shell and D according to H8 / h7;
Drive with the output shaft hole with the use of clearance fit, the interval of 0.
2 to 0.
5mm。
4, variable speed drive bearing axial positioning: will any of its three laps after axial positioning, do not need other two shaft axial position again.
5, the rotation direction positioning;
Both outer and inner ring is flat key position.
The circle is the use of 6, variable speed drive bearing on the radial location can bear the external force of smaller, as shown in figure 5, but unfavorable under high work load.
7, transmission ratio, all is according to the first installation of transmission ratio.
If the other installation, should according to the calculated ratio in table 1.
8, at the rated speed (
1500rpm)
, according to the transmission ratio and the required power (
千瓦)
According to table 2 select variable speed drive bearing type.
9, when based on the working torque, select model according to table 3.
10, reducer type selection in accordance with variable speed drive bearing model.
