Method and system for applying pre-stretch to shaft and component connection

Abstract

A method of securing two components under this disclosure could be said to include receiving an input including a commanded pressure for achieving a pre-stretch on a shaft housed within a fixture. The shaft is coupled to a first component and extending through a second component. In response to receiving the input, causing hydraulic fluid to be provided to the fixture at a pressure based on the commanded pressure, to initiate the pre-stretch on the shaft. A measured stretch of the shaft is received from a sensor. Determining if the measured stretch is within a range of acceptable stretch; and based on a determination that the measured stretch is within the range of acceptable stretch, causing an indication of acceptability. The indication of acceptability being an instruction to tighten a nut to secure the shaft to the second component. A system and a controller are also disclosed.
