Choosing the most suitable type of coupling in a servo application may be a confusing thing, because it is a complicated process to select a coupling for a servo system.Including torque, shaft deviation, hardness, speed, space requirements, etc., the coupling needs to meet all of these in order for the system to operate normally.Before choosing a coupling, we need to have a detailed understanding of the properties of these couplings and their applications. Different types of couplings have their own advantages and disadvantages.
Choosing the right servo coupling is an important part of the overall system design, which will greatly affect the overall performance of the system.In the design process, the coupling should be considered as early as possible, and the system, function, and target arrangement of the coupling should be compared separately, so as to avoid the problems that often occur in the actual application of motion control.
Under normal circumstances, plum couplings are widely used in spindle servo motors, and diaphragms are used in transmission servo motors, such as CNC milling and CNC lathes. The XY axis of CNC milling belongs to the transmission servo motor, and it is often used in forward and reverse rotation. The diaphragm is better than the plum blossom. The spindle servo motor of the CNC car uses plum blossoms. The plum blossoms are cheaper than the diaphragm. For the same size, the rotation limit of the plum blossoms is smaller than that of the diaphragm. The plum blossoms are shock-resistant and allowable shafts. The directional deviation is larger than that of the diaphragm, but the greater the deviation, the faster the pad in the middle wears, and the sensitivity and precision of the diaphragm are higher.
Each type of coupling has its own characteristics and is suitable for different applications. At present, there are various types of couplings on the market for design engineers to choose. The most suitable coupling makes the system performance optimal and has a long service life.
