Problems solved by technology
[0003] There are two types of traditional shaft couplings. One is to compress the shaft through the screws at both ends to transmit torque and support the transmission shaft. The transmission torque is small and the support is unreliable; Large centrifugal force, not suitable for high-speed rotation, and complex processing technology, high cost; another coupling is composed of locking sleeve, bolt, compressor coupling, intermediate body, bolt, motor coupling, and the structure is more complicated , the processing cost is high, the structure is large, it is only suitable for large-scale units to connect and drive, and the scope of use is limited

The invention relates to a shaft coupling, which includes a shaft coupling body and lock nuts, two of the lock nuts are provided, and the two lock nuts are respectively installed at both ends of the shaft coupling body; The main body of the shaft coupling is provided with a claw portion, and after the lock nut is installed, pressure is exerted on the claw portion radially inward, so that the claw portion is locked with the shaft. The coupling provided by the present invention adopts a structure in which the jaws are deformed by force to press the input and output shafts, and locked by the lock nut, which can transmit greater torque and make the connection more reliable; the jaws are evenly distributed and the center of mass is centered , suitable for high-speed rotation requirements; the main body of the coupling and the lock nut can be processed by injection molding or turning, and the material can be plastic or metal. The processing is simple, the cost is low, and the structure is compact. wider.
Description
technical field [0001] The invention relates to a shaft coupling. Background technique [0002] A coupling is a mechanical part used to connect two shafts in different mechanisms so that they rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of buffering, damping and improving the dynamic performance of the shafting. Generally, the power machine is mostly connected with the working machine by means of a coupling, and the coupling is the most commonly used connecting part for shaft transmission of mechanical products. [0003] There are two types of traditional couplings. One is to compress the shaft through the screws at both ends, which transmits torque and supports the drive shaft. The transmitted torque is small and the support is unreliable; Large centrifugal force, not suitable for high-speed rotation, at the same time, the processing technology is complicated and the cost is high; the other cou...
