Coupling is the mechanical drive which is mainly used for connecting shaft and shaft (sometimes coupling spindle other rotary parts) with the transfer motion and torque, and also it is the commonly used components used for safety devices. Mechanical running can’t be separated from two axis; Only be separated in the mechanical parking and coupling apart from two axis.
In addition, coupling is able to complement the axial direction, angular and shaft end-play and absorb vibration, thus it can prolong mechanical life, improve the operation quality and stability of the machine.
lIt must be calibrated and adjusted when installing the coupling.
lMisalignments are sometimes caused not only by equipment assembly, but also by vibration, heat expansion, wear of bearings, etc, during operation. Therefore, it is recommended to adjust the shaft misalignment to be below 1/3 of maximum values.
lThe allowable axis deviation of coupling contains the following three types:
Calculate Motor Torque
When we know the motor watt, we can calculate the motor torque using the following formula.
Motor torque T(N. m)=kW×9550 rpm
Calculate Coupling Torque
When calculate the motor rated torque and select the adjustment factor, the coupling torque can calculate using the following formula.
T1: Motor rated torque K1: Operating Coefficient by Load Character
K2: Corrected Coefficient by Operating Hours
K3: Corrected Coefficient by Start and Braking
Load Character K1
Operating Hours FactorK2
Start and Braking Frequency Coefficient K3
Main Couplings Attachment Type:
Setscrew type:Two setscrews have a angle of 90 °, this low-cost type features the most conventional attachment. However, the point of setscrew may cause damage to the shaft and may be difficult to remove.
Clamp Type:This type is clamped on the shaft by tightening the socket head cap screws. Attachment and removal is easy, and no shaft damage results.
