Elastic Coupling

Elastic Coupling

 

a device used for the longitudinal joining of two rotating parts of a machine (usually shafts), designed to compensate for the relative displacement of the parts’ axes and to absorb the shocks caused by joining the parts. The elastic component of the coupling may be made of metal, as in a coil spring, or a nonmetallic material, as in a rubber doughnut.

Abstract: The paper describes the modal analysis used to extract the natural frequencies and mode shapes of a flexible membrane from elastic coupling structure.
It is necessary and adequate to perform some complexe researches on flexible intermediary membranes from elastic coupling structure, which would lead to working optimization on a long period, with favorable results in what concerns life and safeness of the system (Dobre, 2004).
Available in sizes 40 to 71, the series offers several shaft options, and an elastic coupling ensures smooth start/stopping to minimize strain on the machine, motor and gear.
Secondly, the stabilizer uses an elastic coupling to take the "kick" out of the bow and make it jump less in your hand, thereby improving accuracy.
