Abstract

A strain wave gear includes gear elements including a circular element having an internally-toothed gear and a flex element having a flexible externally-toothed gear arranged in the circular element. A wave generator is rotatably arranged in the flex element and configured to flex the externally-toothed gear in a radial direction to partly mesh the internally-toothed gear and the externally-toothed gear. Support elements include a bearing input support element and a bearing output support element rotatably coupled to the bearing input support element. Elements of the support elements are fixed respectively to elements of the gear elements. An encoder arrangement includes an encoder track and an encoder reader. A part of the encoder arrangement is between an element of the support elements and an element of the gear elements.
