Abstract
A shell for a universal joint for flexibly coupling two rotary shafts. The shell is constructed using a manufacturing technique to produce a shell of light weight and excellent strength. The shell generally has a hollow cylindrical configuration and is secured at one end to a rotary shaft and formed to have a plurality of grooves extending parallel to its cylindrical axis. A second rotary shaft includes portions which engage the plurality of grooves for transmitting movement from one shaft to the other through the shell. The shell may be formed using a tubular work piece or a planar work piece, and may be provided in substantially complete form by use of a machine press prior to subjecting the material to an ironing process to make the grooves of accurate shape and dimension. The process is performed such that no machining is required to form the grooves and produce the shell.
