AI Technical Summary
Technical Problem
Existing diaphragm couplings are prone to keyway deformation under high torque, and flange connections require high alignment accuracy, resulting in low stability and high maintenance costs.
Method used
The coupling side section adopts a double keyway structure, combined with set screws and connecting bolts. By setting a keyway on the inner wall of the first cylinder of the coupling side section and installing set screws at the keyway, the force on the key and keyway is evenly distributed, reducing the extrusion force. Combined with a stainless steel diaphragm, elastic compensation is provided.
Benefits of technology
It improves torque transmission capability, reduces keyway wear and deformation, enhances connection stability and service life, and reduces maintenance costs.
