Abstract
A drive coupling having a flexible web joining a pair of hubs and including at least one undulation. The undulation has an axis extending substantially at a right angle to the longitudinal axis of the coupling with all sections of the web cut by transverse planes normal to the longitudinal axis of the coupling being substantially parallel.
Claims7
A unitary one piece flexible coupling for transmitting rotational torque comprising:
- a relatively rigid drive hub connectable to a driving member;
- a relatively rigid driven hub connectable to a driven member;
- and at least one relatively thin web formed of the same material as said hubs integrally with and thereby joining said driven hub to said driven hub and including at least one undulation in said web, said web having an axis of curvature extending substantially at a right angle to the longitudinal axis of said hubs with all sections of the web cut by a transverse plane at right angles to the longitudinal axis of the coupling being substantially parallel, said undulating thin web forming a relatively flexible connection between said relatively rigid hubs.
A unitary one piece flexible coupling for transmitting rotational torque comprising:
- a relatively rigid drive hub connectable to a driving member;
- a relatively rigid driven hub generally aligned with said drive hub and connectable to a driven member;
- and at least one unitary relatively thin web formed of the same material as said hubs integrally with and thereby joining said hubs and including at least one undulation in said web, said web having an axis of undulation extending substantially at a right angle to the longitudinal axis of said hubs and being flat in the direction of said axis of undulation with all sections of the web cut by a transverse plane at right angles to the longitudinal axis of the coupling being substantially parallel, said undulating thin web forming a relatively flexible connection between said relatively rigid hubs.
