Abstract
A strain wave gear system () includes first and second sets of ball bearings () located intermediate a flange () and a retainer plate () rotatable with an output () and a radially oriented flat disc () of the input including strain relief (). Strain relief () is a helical slot in a coupling () located radially within the wave generator () and the ring gear (). The ring gear () is sealed by a sealing system including sealant () forced by a protrusion () of the cap () entering into a cavity () through a channel () into a relief volume () of the housing (). The bearing () rotatably mounting the housing () to the output () is lubricated by a lubricating system including plungers () threadably received in axial bores () intersecting with radial bores () in communication with radial holes () of the bearing ().
