Radially interengaged vane coupling with circumferentially arranged resilient pads

摘要

A flexible shaft-coupling device comprises an annular first coupling member having circumferentially spaced vanes extending radially inwardly from its inner periphery and a second coupling member located within the annular coupling member. The second coupling member has circumferentially spaced vanes extending radially outwardly so as to protrude into the spaces between the vanes of the first coupling members. Resiliently distortable pads are located between adjacent vanes to enable torque to be transmitted between the vanes by compression of the pads. The pads are formed of laminations of resilient and less resilient materials. The device may be located within one end of a hollow shaft connected to the annular first coupling member.
