Elastic spider coupling

1.Product presentation:

Elastic spider coupling is a common elastic coupling, it transmits torque by mechanical structure, and uses the intermediate elastic spider to compensate misalignment. This product features small structural size, light weight and high transmission torque. Coupling with elastic spider is a torque elastic coupling, the claw shaped teeth of two coupling halves stagger by half a tooth pitch on the circumference, with an elastic spider inlaid in their gap, and the connection of driver with the driven machine is realized by the elastic spider between the claws of the coupling halves. Coupling with elastic spider has the fail-safe protection function, can effectively damp and reduce the vibration and impact during operation, and effectively correct the axial, radial and angular installation deviation.

2.Product features:

  • Torsional elastic and maintenance free;

  • High transmission efficiency and reliable operation; 

  • Compact structure design, simple structure with low inertia; 

  • 2.4.Ableto transmit high torque, with good damping performance;

  • 2.5.Axialinserted mounting, with fail-safe protection function;

  • 2.6.Good dynamic characteristics, vibration absorption and low noise; 

3.Product development:

The elastic body of an ordinary elastic coupling is subjected to bending stress and pressure due to the existence of installation deviation, making it easy to wear and shortening the service life of the coupling. In a elastic spider coupliner, the elastic spider, with its drum shaped teeth design, is only subjected to pressure during service, therefore it can withstand higher load and transmit larger torque, and the maximum torsion angle of the spider can be 3-5°. The elastic spider is resistant to wear, oil, oxidation and aging, and its water resistance makes it suitable in tropical climate areas.

Presently, our products are in two categories, one is for axial inserted mounting without the need of nut, suitable to applications with small operation space and unit with protective shield; the other is for use in heavy machinery, with its structure able to realize radial mounting and dismantling without moving the machine.

4.Product application:

Couplings with elastic spider are widely used in applications such as metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pumps and fans.
