The plum blossom elastic coupling has a simple structure, a small number of parts, a small radial dimension, and no need for lubrication; the elastic element has a high load-bearing capacity under pressure.Except for the double-flange plum blossom elastic coupling, the half coupling must be moved axially when replacing the vulnerable plum blossom elastic parts.This kind of coupling has a certain ability to compensate the relative offset of the two shafts.The cross-section of the plum petals of the plum elastic coupling is usually circular, which can improve the uniformity of the load distribution on the working surface, and can transmit larger torque, but the elasticity is slightly reduced.It can also be made into a rectangle or fan shape.When the coupling is working, the plum petals are squeezed, and only half of the plum petals carry work.Quincunx...

　Key points for coupling selection: ① Allowable rated torque-is the allowable value of torque that the coupling bears during actual use. ②Maximum allowable torque-is the maximum critical value for damage to the coupling during use. ③Maximum allowable speed-It is necessary to make sure that the speed of the motor is within this range when selecting the model. ④ Allowable eccentricity-the allowable value of the parallel deviation of the axis of the two shafts. ⑤ Allowable deflection angle-the allowable value of the mutual angle formed between the two shafts. ⑥ Allowable axial deviation-the allowable value of the displacement of the two shafts in the axial direction.When starting, stopping, and switching between forward and reverse rotation, the motor will apply a load greater than the maximum torque of the motor to the coupling, so...
