Fixed screw
Plum couplingAlso called claw coupling, it is composed of two metal claw discs and an elastic body.The two metal claws are made of No. 45 steel, but aluminum alloy or stainless steel is also used when load sensitivity is required.The advantages of positioning screws to fix the Torx coupling are:
1. Simple structure, easy installation and maintenance, oil resistance and electrical insulation, dimension-free torsional elasticity, intermediate elastic body connection, good dynamic characteristics, and long service life.
2. The main shaft sleeve is made of aluminum alloy, which is lightweight.
3. The transmission torque is large and maintains good accuracy.
4. The characteristics of clockwise and counterclockwise rotation are exactly the same, and there is no backlash.
5. Compact design and low moment of inertia.
6. Vibration can be absorbed, and axial plug-in installation.
