摘要： The stator for a helical gear device is formed of a plurality of duplicate disks. The disks each include a convoluted cavity having equally spaced symmetrically radially extending lobes for receiving the convex lobes of the rotor. The disks are assembled into the form of a stator by inserting the disks about a mandrel which includes convoluted lobes, so that the convoluted cavities of the disks follow the shapes of the lobes of the mandrel, thereby causing the disks to be progressively radially offset with respect to one another along the length of the stator. The stacked disks are inserted into a heated cylindrical housing so that the housing forms a shrink fit about the disks. The disks and housing are further connected by brazing, and the disks optionally have openings formed between the lobes which function as convoluted channels through the assembled stator for the passage of liquid, wiring, etc. through the stator.
