摘要： The utility model relates to internal cycloidal gear mechanisms and can be used in various branches of mechanical engineering as working members of hydraulic machines (pumps and engines), compressors, internal combustion engines, as well as in planetary gearboxes, in particular in technical systems for drilling and repairing oil and gas wells. The problems to be solved by the utility model include the improvement of the quality of the process of designing working members having a cycloidal tooth profile, as well as the substantiation of the conditions for modifying cycloidal face profiles (by choosing the required combination of dimensionless gearing coefficients) in order to achieve the maximum or minimum open area of the gerotor mechanism having a different kinematic ratio.

摘要： A displacement type rotary machine with non-rotatable housing, two mutually movable co-axial rotors includes an outer rotor movable along housing inside wall, and an inner rotor movable relative to an inner circumferential face of the outer rotor. The outer rotor has radially inwardly directed wings. The inner rotor has a hub with radially outwardly directed wings. Each inner rotor wing is movable between a pair of the outer rotor wings to create chambers. A free end of the inner rotor wings is movable adjacent a curved inside wall of the outer rotor. A free end of the outer rotor wings is movable adjacent the hub. Both rotors are movable adjacent a first cover on the housing. The inner rotor is in movable adjacent a second cover on the outer rotor. Controlling gears control movement of the rotors, the gears including elliptical gearwheels and circular gearwheels.

摘要： A novel rotating body, its material, and manufacturing method thereof, shortening a distance for cutting a bore surface in its axial direction, reducing processing costs, enabling lower-cost manufacture of inner rotor. A metallic rotating body 11 has a bore surface 12 for press-fitting a shaft thereinto, including a cutting-processed portion 13 at first end and an unprocessed portion 14 at second end. The processed portion 13 has an inner diameter formed smaller than the unprocessed portion 14. A chamfer 15 at first end of the bore surface 12 is cut, while a chamfer 6 at the second end not. A bore surface 2 of material 1 processed into the rotating body 11 includes a small-diameter portion 3 at first end and a large-diameter portion 4 at second end. A step 5 is formed between the small- and large-diameter portions 3, 4, with the chamfer 6 formed at second end.
