Abstract
An assembly of a universal joint member and a shaft having a plurality of superimposed layers of material and an adhesive bond between axially inter-fitting parts of the shaft and universal joint member, the adhesive bond being established with more than one of the layers of material of the shaft to overcome a tendency to disruption of the layers of the shaft on torque transmission. The axially inter-fitting parts may be of stopped or frusto-conical form to provide a joint surface which intersects several of the layers of the shaft.
Claims5
An assembly of a universal joint member and a shaft, said shaft including a plurality of radially superimposed layers of fibre reinforced resin material, the joint member and shaft having axially inter-fitting parts and an adhesive bond being established between the joint member and shaft by inclusion of an adhesive substance therebetween, said axially inter-fitting parts of the joint member and shaft being of stepped configuration whereby said adhesive bond is established with a plurality of said layers of material of the shaft in generally cylindrical areas at different radii.
An assembly of a universal joint member and a shaft, said shaft including a plurality of radially superimposed layers of fibre reinforced resin material, the joint member having a part which fits within an end portion of the shaft and which has an exterior surface of tapering configuration, said end portion of the shaft affording an interior surface which tapers from the end of the shaft, said part of the joint member intersecting a plurality of the layers of material of the shaft and an adhesive bond being established between said surfaces of the universal joint member and shaft.
