Abstract
A strain wave gearbox configured to provide over-torque protection. The strain wave gearbox is designed to include a clutch that is at least partially housed within or positioned inside the internal space (herein labeled a chamber or void space interchangeably with internal space) of a flex spline. In some cases, the internal space is utilized to generate the preload for the clutch, and it may be used to provide room for a clutch preload subassembly. The clutch is located outside the flex spline's internal space and is formed to use geometric friction surfaces in the form of mating rings of teeth on mating surfaces or sides of the first and second clutch plates that once preloaded by the clutch preload subassembly require a greater torque than the design torque to rotate to the next tooth.
