Removal tool for servo horn with spline-shaft coupling

Abstract

A device to remove a metal servo horn in an efficient way by utilizing the lifting force to separate servo horn from a servo output shaft when screw is rotated counter-clockwise and hits against the concave of lower surface of upper front plate of the device. Clamping force provided by two fastening members combines the device and servo horn into one integrated unit to avoid the distortion of open end of the device when lifting force is greater than rigidity of the device. When a lifting force for removing the integrated unit is applied in direction opposite to installing direction of servo horn, it overcomes the friction between the inner splines of servo horn and the outer splines of servo output shaft then separates both splines. The removal of the servo horn from the servo output shaft is achieved.
