摘要： A comparator tool is provided for evaluating the profile of a multi-lobe helical rotor. The comparator tool includes a housing with a first end and a second end and an internal bore extending from the first end to the second end. The internal bore includes a first diameter having nominal clearance for an original equipment manufacturer (OEM)-specified major diameter of the rotor, a second diameter having nominal clearance for an OEM-specified minor diameter of the rotor, and multiple helical grooves corresponding to a number of lobes in the helical rotor. Each of the multiple helical grooves has nominal clearance for an OEM-specified tip diameter of the rotor. The comparator tool slides along the length of the rotor and provides visibility of an interface between a circumference of the rotor and the first end at any place along a length of the rotor.

摘要： 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.

摘要： A progressive cavity pump includes at least one of a jacketed stator casing and a jacketed inlet body. The jacketed stator casing includes a stator heating chamber, a stator assembly, and a rotor rotatably disposed within the stator assembly. The stator heating chamber forms a first space around the stator assembly and receives heating fluid therein. The stator assembly includes a cylindrical wall and a stator segment that forms a helically-convoluted chamber within the cylindrical wall. The jacketed inlet body includes an inlet heating chamber and a working fluid chamber in fluid communication with the helically-convoluted chamber. The inlet heating chamber forms a second space around the working fluid chamber and receives heating fluid therein. The stator heating chamber and the inlet heating chamber are isolated from each other, the helically-convoluted chamber, and the working fluid chamber.

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。
