Coupling classification and selection skills

　　Couplings belong to the category of general mechanical parts and are used to connect two shafts (active shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque.In the high-speed and heavy-duty power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting.The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.Generally, power machines are mostly connected with working machines by means of couplings, which are commonly used connecting parts for shaft transmission of mechanical products. In the late 20th century, coupling products at home and abroad have developed rapidly. When designing products, how to select couplings that can meet the requirements of the machine from a variety of couplings with different performances? For most designers, it is always It is a troublesome problem.Commonly used couplings include diaphragm couplings, gear couplings, plum blossom couplings, slider couplings, drum gear couplings, universal couplings, safety couplings, elastic couplings And serpentine spring coupling.

　　2. When selecting, please note that the rated torque in the data is greater than the system load torque. The rated torque has taken into account the variable load factors during operation, so there is no need to adjust the rated torque value when selecting.When selecting the size of the coupling, please note that the load torque generated by continuous operation should be lower than the rated torque.
　　3. Please confirm that the designed aperture and rotation speed conditions cannot exceed the large aperture and high rotation speed in the data.Please change the size when either the large bore diameter or the high rotation speed cannot meet the design conditions.
