Abstract

Drive shaft coupling involving multi lamellar spoked rubber flanges with link bolts on a pair of in-line shafts, are modified by use of sleeves with integral spaces to locate the waists to the spokes and prevent mutual abrasion in response to resonant vibration etc. The sleeves/spacer are moulded from material which can deform under the conditions of service, pref. are of neoprene or silicone rubber, polyamide or halocarbon polymer. Spacers of similar thickness are fitted between adjacent rubber spokes or cores mounted on the assembly bolts. Esp. suitable for elastic linkages in driveshaft couplings for aircraft components, because of the low wt. and bulk and ease of fitting/replacement.
