Abstract
Abstract A power transmission including universal joints for transmitting power between two shafts which are inclined to one another, such as between the shaft of the engine and the propeller shaft which extends at an angle from the engine shaft. The transmission includes a gear housing having an angled housing in which one of the universal joints is rotatably journaled and also includes another universal joint located outside of the angled housing. The universal joint which is located within the angled housing accommodates approximately one-half the angle between the engine shaft centerline and the propeller shaft centerline. The second universal joint located externally of the housing accommodates the remaining angular displacement between the shafts and serves another function of acting as a flexible joint to compensate for small additional angular misalignment between the engine and the propeller shafts which may occur due to manufacturing and installation tolerances, hull deflections, flexible engine mounts, etc. A lubricating means including an impeller driven by the universal joint is located within the angular housing, which impeller forces oil through a conduit and to an antifriction bearing assembly to assure a flow of oil through the assembly and also good circulation in other parts of the transmission.
