Abstract

See full text

A semi-rigid stator is provided for a helical gear device. The stator includes a stack of rigid rings, a deformable layer, and a rigid housing. Each of the rigid rings has a central opening and an exterior surface. The rigid rings are aligned along a common centerline and rotated slightly relative to each other such that the stack of rigid rings forms a helically convoluted chamber. Each of the rigid rings is secured within the rigid stator housing by the deformable layer disposed between the exterior surface of each of the rigid rings and the rigid housing. The deformable layer bonds the rigid rings together as the ring stack and permits movement of the rigid rings relative to each other.
