Abstract: A global shaft coupling assembly includes first and second hubs adapted to be mounted on first and second shafts to be coupled. The first and second hubs each include a plurality of groups of axially-spaced and axially-aligned apertures. The coupling assembly also includes a pair of composite members positioned around the shaft ends. The composite members include first and second sleeves each having a plurality of groups of apertures. Various ANSI and ISO standard shaft spacings may be obtained by aligning the various hub and sleeve apertures and fastening the hubs and sleeves together with cap screws.

Abstract: Disclosed herein is an elastomeric coupling for transmitting torque between two shafts approximately aligned on a shaft axis, the coupling comprising a composite arcuately extending member including a shoe having a first portion and a second portion extending from the first portion and adapted to be connected to one of the shafts, and an elastomeric center element having, in a radial plane extending from and along the shaft axis, an inwardly opening generally U-shaped cross-section defined by two axially spaced radially extending leg portions respectively including an inner part bonded to the first portion of the shoe, and an outer part, and an axially extending bridge portion connected to the outer parts and including a weakened area which is located remotely from the shaft axis and which facilitates tearing of the bridge portion at the area in response to excessive transmission of force as compared to tearing of the bridge portion at other areas.
