JOINT FOR CONNECTING SECTIONS OF A MEMBER SUBJECT TO CYCLIC COMPRESSIVE LOADING

摘要

A joint for connecting sections of a member which is subject to cyclic compressive loading. Such joints are used, for example, in the piston rods of single-acting reciprocating pumps, and may fail through fatigue. The joint comprises a stud threadedly engaged with the end of at least one of the sections, and means surrounding the stud and transmitting loads independently of the stud. The stud has a substantially lower modulus of elasticity than the load-transmitting means.
