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: 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: 用于螺旋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，轮廓具有与转子凸部的凸部相互作用的等间距或开放的凸角。 盘彼此粘合以形成在其中限定螺旋卷绕的细长室的盘堆叠。 支撑环同心地固定在磁盘组的相应端部磁盘上。 环的内径基本上等于由盘的径向延伸的凸角限定的中心孔的大直径。 当转子旋转并在定子内章动时，其通过接触转子叶片的尖端的支撑环支撑在盘叠的两端。 因此，转子运转惯性的全部力量不仅仅是由磁盘承担，从而延长了它们的使用寿命。

Abstract: A progressing cavity pump has a rotor (62) that moves in an eccentric motion, and is driven by a drive shaft (20) that rotates about a fixed axis. In order to connect the two a coupler (10) is proposed that comprises two parallel plates (12, 14); one with several pins (16) protruding from it, and the other with the same number of holes (28) in it. The holes (28) are sized to allow the eccentric motion of the rotor (62). There may also be a ball (18) between the two plates (12, 14) to transmit loads between the plates.

Abstract: Gear pumps use various types of bushings or bearings (sleeves) between a shaft and the housing of the pump. From time to time, these sleeves wear out and have to be replaced. This extractor removes the sleeves and includes three main components - a collet or sleeve engaging member, a mounting bracket, and a lift screw. The extractor may also include other components within the scope of the invention, including melting screws and washers.

Abstract: Toothed gears and lobed gears intermesh to create large volume pockets in gear sets of a given size. The pockets are larger than the pockets that exist in current tooth or lobe pumps and provide the benefit of a pump that better handles shear sensitive liquids. The toothed gears and lobe gears are preferably involute-shaped and improve upon standard spur and helical gear designs by omitting alternate teeth on the standard toothed gears and filling in corresponding gaps on the mating standard lobed gears. Additional tooth and lobed gear rotors may be added in tandem as additional pairs of gears to the shafts and circumferentially offset to provide driving tooth engagement between at least one pair of the toothed and lobed rotors at every point around the rotational circumference of the rotors. This spur gear or helical gear configuration eliminates the need for separate driving/synchronizing gears.

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.
