Background
The coupling is a mechanical part for coupling two shafts (a driving shaft and a driven shaft) of different mechanisms to rotate together to transmit torque. The coupling between two shafts requiring coaxiality is usually a rigid coupling, such as a flange coupling specified in the chinese national standard GB/T5843-2003, which is a rigid coupling, in which two half couplings with flanges are respectively connected to two shafts by using a common flat key, and then the two half couplings are connected into a whole by using bolts to transmit motion and torque. The drawbacks of rigid couplings are: the two shafts need to be strictly coaxial, the requirement on position precision is high, and the adjustment is troublesome.
The universal coupling can overcome the defect of different shafts between two shafts, so that the two shafts are not on the same axis, the two connected shafts can continuously rotate under the condition of an included angle of the axes, and torque and motion can be reliably transmitted; however, the universal coupling is usually of a cross-axle type or a rzeppa type, and has a complex structure, high requirement on manufacturing precision and high manufacturing cost.
For example, in the single-screw type papaya crusher, a motor and a screw are coaxially arranged; a lifter, a motor and a screw rod are coaxially arranged in the papaya processing process; in both cases, the coupling used is a rigid coupling, which has high requirements for manufacturing accuracy and high manufacturing costs.
