Abstract:
[0058] A coupling assembly (20, 120, 220) and method can include a first rotatable member (22, 122, 222) and a second rotatable member (26, 126, 226) defining a cylindrical hub portion having a plurality of springs (42, 142, 242) interposed between the cylindrical hub portion of the second rotatable member (26, 126, 226) and the first rotatable member (22, 122, 222) for transferring rotational torque between the first and second rotatable members. A plurality of load-bearing surfaces (32, 132, 232) associated with the first rotatable member (22, 122, 222) are engageable by the plurality of springs (42, 142, 242) to accommodate radial clearances (34, 36, 134, 136, 234) between the first rotatable member (22, 122, 222) and the cylindrical hub portion while providing rotational drive torque from the first rotatable member (22, 122, 222) to the second rotatable member (22, 122, 222) through the plurality of springs (42, 142, 242).
Abstract:
A multiple natural frequency coupling apparatus (10) for connecting a rotatable driving member to a rotatable driven member of a drive line. The coupling apparatus (10) of the present invention provides a substantially cylindrical housing (12) having a longitudinal axis (13) with a substantially cylindrical outer shaft (34) coaxially aligned with and connected to the housing (12). A substantially cylindrical inner shaft (38) is coaxially aligned with the outer shaft (34) and the housing (12). A substantially cylindrical fluid chuck housing (26) is coaxially aligned with the housing (12), the outer shaft (34), and the inner shaft (38) wherein the fluid chuck housing (26) is connected to the inner shaft (38). A substantially cylindrical collapsible sleeve (50) is coaxially aligned with and between the fluid chuck housing (26) and the outer shaft (34), wherein the collapsible sleeve (50) may move between a non-actuated position, wherein the collapsible sleeve (50) does not engage the outer shaft (34) thereby providing the coupling apparatus (10) with a first torsional stiffness corresponding to a first natural frequency, and an actuated position, wherein the collapsible sleeve (50) engages the outer shaft (34) thereby providing the coupling apparatus (10) with a second torsional stiffness corresponding to a second natural frequency.
