Abstract: 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 consists of 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 portion allowing continued motor operation at reduced efficiency, if the elastomer part failed in service. The application also discloses combinations of a regular disk stack with a rubber lining, a rigid material disk stack and a circular rigid sleeve which react to rotor sideloading while permitting proper rotor orbiting.
Abstract translation: 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泵送工作流体时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。 本申请还公开了一种规则的磁盘堆叠与橡胶衬套,刚性材料盘堆叠和圆形刚性套管的组合,其在允许适当的转子轨道运动的同时对转子侧面加载作出反应。

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.
