Economical plum blossom coupling

Structural features

Plum blossom main structure: This type of coupling is mainly composed of two metal claws with convex teeth and a plum blossom-shaped elastic body. The common materials of metal claws are 45# steel or aluminum alloy. The claws made of 45# steel have high strength and good toughness, and can withstand large torque and load; the claws made of aluminum alloy are lighter, which is conducive to reducing the overall weight of the equipment, improving the operating efficiency of the equipment, and have good corrosion resistance.

Screw fixing and clamping design: By tightening the screws, the various parts of the coupling are tightly connected together. On the one hand, the screws fix the metal claw plate on the shaft to prevent it from axial and radial displacement during operation; on the other hand, the clamping structure further enhances the tightness of the connection, ensuring that there will be no looseness between the coupling and the shaft under high speed and high torque conditions, ensuring the reliability of power transmission.

Performance characteristics : excellent shock absorption and buffering performance , strong displacement compensation ability , high torque transmission efficiency , good concentricity and balance performance

Material selection

Metal parts: In addition to the 45# steel and aluminum alloy mentioned above, stainless steel may also be used under some special working conditions. Stainless steel has excellent corrosion resistance and is suitable for corrosive environments such as moisture, acid and alkali, which can ensure the long-term stable operation of the coupling in harsh environments.

Elastomer: Polyurethane plastic is a commonly used elastomer material, which has the characteristics of wear resistance, oil resistance, aging resistance, good elasticity, etc. It can maintain stable performance in a wide temperature range, effectively transmit torque and absorb vibration 1910.
