Abstract: A stator for a helical gear device is formed from multiple rigid disks and support rings bonded to the disks. Each disk forms part of a profile having equally spaced or opened lobes which interact with the convex portions of rotor lobes. The disks are bonded to one another to form a disk stack defining a helically convoluted elongated chamber therein. The support rings are fixed concentrically against respective end disks of the disk stack. The rings have an inside diameter substantially equal to the major diameter of the central aperture defined by the radially extending lobes of the disks. As a rotor rotates and nutates inside the stator, it is supported at both ends of the disk stack by the support rings touching tips of the rotor lobes. Thus the full force of the rotor's operational inertia is not borne by the disks alone, thereby increasing their life.

Abstract translation: 用于斜齿轮装置的定子由多个刚性盘和结合到盘的支撑环形成。 每个盘形成轮廓的一部分，其具有与转子瓣的凸部相互作用的具有等间距或开口的瓣。 这些盘彼此粘合以形成在其中限定螺旋卷积的细长室的盘叠。 支撑环与磁盘堆叠的相应的端盘同心地固定。 这些环的内径基本上等于由圆盘的径向延伸凸起限定的中心孔的大直径。 当转子旋转并在定子内部旋转时，它通过接触转子叶片尖端的支撑环支撑在盘片堆叠的两端。 因此，转子的操作惯性的全部力量不是单独由磁盘承担的，从而增加其寿命。

Abstract: A fluid displacement apparatus includes a stator section with a rotor therein. The stator section includes a cylindrical casing, a helically-convoluted chamber section within the cylindrical casing, and a rigid sleeve within the cylindrical casing and separate from the helically-convoluted chamber section. The rigid sleeve includes a circular internal bore. The rotor is rotatably disposed within the cylindrical casing. The rotor includes a helically-lobed section disposed within the helically-convoluted chamber section, and a circular cylinder section disposed within the rigid sleeve. The circular cylinder section provides a fluid passageway between the rigid sleeve and the circular cylinder section. Side loads from the rotor are distributed along a contact line at any point of rotation of the circular cylinder section within the rigid sleeve.

Abstract: ABSTRACT There is described a method for forming a circular cylinder section over a helically lobed section of a rotor, the method comprising: obtaining a helically-lobed rotor for modification; selecting a cylinder shell corresponding to a major diameter of the helically- lobed rotor; reducing the major diameter of a portion of the helically-lobed rotor, wherein the reducing forms a reduced-diameter section that is nominally smaller than an inner diameter of the cylinder shell; and securing the cylinder shell around the reduced-diameter section of the helically-lobed rotor.
