Little knowledge of quintuple type elastic coupling

The quincunx elastic coupling is mainly composed of two convex teeth that are closely meshed and subjected to radial extrusion to transfer torque. When the two axes have relative deviation, the elastic element will produce corresponding elastic deformation and play an automatic compensation role. 2. The plum-shaped elastic coupling is mainly suitable for starting frequently, positive and negative rotation, medium high speed, medium torque and high reliability requirements of the workplace, such as: metallurgy, mining, petroleum, chemical, lifting, transportation, light industry, textile, water pump, fan, etc. Working environment temperature: -35 ℃ ~ 80℃, transmission nominal torque 25 ~ 12500Nm, allowable speed 1500 ~ 15300r/min.

Quin-shaped elastic coupling is a kind of widely used coupling, also called claw coupling, is composed of two two metal claw plates and an elastic body. The two metal jaw discs are generally 45 steel, but aluminum alloy can be used for load sensitive applications.

The quin-shaped elastic coupling is composed of two half couplings and elastic components with the same shape of convex claw. The quin-shaped elastic components are placed between the convex claw of two half couplings to realize the connection of two half couplings.

Compared with other couplings, quin-shaped elastic couplings have the following characteristics: (1) stable and reliable operation, with good damping, buffering and electrical insulation performance. (2) simple structure, small radial size, light weight, small moment of inertia, suitable for medium-high speed occasions. (3) With a large axial, radial and angular compensation capacity. (4) High strength polyurethane elastic components are wear-resistant and oil-resistant, with large bearing capacity and long service life. (5) Coupling without lubrication, less maintenance workload, can be continuous long-term operation.
