ISO 9001 factory OEM flexible steel rubber couplings with high quality

1, Conform the working condition of main motor, electric motor, choose the working condition coefficient K value, K value see the chart.
2,Conform the Solleistung of Coupling Pc=P x K
Formula:Pc-Solleistung(Kw)P- Antriebsleistung(Kw)K- application factor 
3, Calculation of coupling of each power value Pc/N(r/min) Formula: n—Transfer speed According to Pc/n value, then choose the type of coupling from the continuous 
4, Review the condition
maximum speed
Peek torque
The shaft end distance of main and electric motor
shaft diameter of main motor and electric motor
The maximum axial misalignment and angular misalignment maximum

Note: If the user can’t find corresponding types of shaft end distance and shaft diameter size, we company can design and manufacture as user’s request.

Instruction of selection

When coupling need Angle to the compensation and the axial displacement at the same time, which allows for the amount of compensation in referring to the following figure curve.Angle to the coupling of the axial force and stiffness can be calculated according to the drawing and parameter data in the table.
