ABSTRACT:
A structural power transmitting component embodies a shaft and a gear or pulley held threadedly positioned on the shaft by four nuts while interconnected by a torque transmitting wedge and key. The shaft is especially configured to establish structural interrelationships with the nuts, wedge, key and gear so as to facilitate assembly and disassembly of the component as well as to maintain the wedge and key deformed under engagement by the nuts to avoid development of internal clearances during start-up and stoppage of torque transmission to thereby preclude generation of noise during such operational start-up and stoppage of transmission through the component.
