Abstract
Abstract A flexible coupling device for accommodating both parallel misalignment and axial misalignment employs an elastomeric sleeve between the driving member and driven member. One of the members has radially projecting axially extending fins received within internal recesses provided in the elastomeric sleeve. The elastomeric sleeve has a series of external bulbous projections each received within a pocket provided in said other member.

Claim 1
Independent Claim
138 words
A flexible vibration-dampening coupling for connecting a driving member to a driven member, comprising in combination: one of the members comprising a hub having axially extending fins projecting radially outward, each fin being provided with a crowned outer surface extending axially, the other member comprising a sleeve having a series of circumferentially spaced internal pockets, a continuous liner formed of elastomeric material and fixed within said sleeve, said liner having a series of bulbous projections each received within one of said pockets, respectively, the finned member and the elastomeric liner defining clearances spaces between them in the regions between adjacent fins, each bulbous projection having an axially extending internal recess for axial reception of one of said fins, whereby said members may be separated axially through relative axial movement in which said fins slide out of said recesses.
