摘要： A hybrid elastomer/metal on metal motor for a helical gear device includes a rotor and stator comprising a hydraulic motor that produces work when a working fluid is pumped therethrough. The improvement involves the stator being, for part of its length, a conventional or even wall stator, using an elastomer to form a seal against the moving rotor. The stator's remaining length comprises a profiled rigid surface that forms a seal directly with the moving rotor. This gives the motor the high efficiency of the elastomer sealing against the rotor, and simultaneously provides a backup of the stator's rigid section allowing continued motor operation at reduced efficiency, if the elastomer part failed in service. The invention also includes combinations of a regular disk stack with a rubber lining, a rigid material disk stack (or unitized element) and a circular rigid sleeve which react to rotor sideloading while permitting proper rotor orbiting.

摘要： A progressing cavity pump has a rotor that moves in an eccentric motion, and is driven by a drive shaft that rotates about a fixed axis. Various means have been used to connect the two; mostly using an intermediate shaft called a connecting rod that has a universal joint at either end. This device replaces that with two parallel plates; one with several pins protruding from it, and the other with the same number of holes in it. The holes are sized to allow the eccentric motion of the rotor. There is also a ball between the two plates to transmit loads between the plates.

摘要翻译：用于螺旋齿轮装置的用于金属电动机的混合弹性体/金属包括转子和定子，所述转子和定子包括当工作流体被泵送通过其中产生作业的液压马达。改进之处在于，定子的一部分长度为常规或均匀的壁定子，使用弹性体来形成对移动转子的密封。定子的剩余长度包括直接与移动转子形成密封件的成型刚性表面。这为电机提供了高效率的弹性体密封抵抗转子，并且同时提供了定子刚性部分的支撑，如果弹性体部件在使用中失效，则能够以更低的效率继续电机运行。本发明还包括具有橡胶衬里的规则盘堆叠，刚性材料盘堆叠（或组合元件）和在允许适当的转子轨道运动的同时对转子侧面加载作用的圆形刚性套筒的组合。

摘要： 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 consisting of radially equally spaced or opened lobes which interact with the convex portions of rotor lobes. The disks are arranged into a desired helical configuration and 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 are sized with an inside diameter substantially equal to the major diameter of the central aperture defined by the radially extending lobes of the rigid disks. As a rotor rotates and nutates inside the helically convoluted elongated chamber of the stator, it is supported at both ends of the disk stack by the support rings touching the 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.
摘要翻译：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，该轮廓包括与转子叶片的凸起部分相互作用的径向等间距或开放的叶片。盘被布置成所需的螺旋构造并且彼此结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。这些环的尺寸大小与内径基本上等于由刚性盘的径向延伸的叶片限定的中心孔的长度的直径。当转子旋转并且在定子的螺旋卷积的细长室内旋转时，其通过接触转子叶片的尖端的支撑环被支撑在盘堆叠的两端。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。
