Inventia se refera la constructia de masini, si anume la transmisiile planetare precesionale.Transmisia, conform primei variante, include un corp cu capac, in care sunt amplasate un arbore conducator si, cinematic legat cu el, executand o miscare de precesie, un satelit cu un dispozitiv ce previne rotirea lui in jurul axei sale, precum si o roata dintata condusa, care interactioneaza cu el. Transmisia este dotata suplimentar cu o bucsa de reazem, amplasata din partea satelitului si fixata pe arborele conducator. Intre suprafata interioara frontala a capacului corpului si suprafata frontala a flansei bucsei de reazem adiacenta ei, de asemenea, intre suprafata frontala a flansei orientata spre satelit, care este executata oblica, si suprafata frontala a satelitului este amplasat cate un rulment axial. Intre dintii satelitului si rotii dintate conduse sunt amplasate liber role conice, numarul carora este egal cu numarul dintilor satelitului sau rotii dintate conduse. Mecanismul ce previne rotirea satelitului in jurul axei sale, include cel putin trei bile situate uniform pe circumferinta, fiecare fiind liber amplasata in locasul executat pe suprafata laterala a satelitului, fiind totodata amplasata in canelura longitudinala executata pe peretele interior al corpului. Transmisia, conform variantei a doua, se caracterizata prin aceea ca include suplimentar o roata dintata centrala, fixata din partea plasarii arborelui conducator opusa rotii dintate conduse, coaxial lui si interactioneaza cu satelitul, de asemenea, cuprinse de ele, doua bucse de reazem, una dintre care este fixata pe arborele conducator, iar a doua, legata rigid cu ea, este montata in butucul rotii dintate conduse cu posibilitatea rotirii fata de el. Suprafetele frontale ale flanselor bucselor de reazem, orientate una spre alta, sunt executate oblice si paralele. ŕ The invention relates to the construction of cars, namely to the precessional planetary transmissions. The transmission, according to the first variant, includes a body with lid, in which a driving shaft is located and, kinematically linked to it, executing a precession movement, a satellite with a device that prevents its rotation about its axis, as well as a driven gear wheel, which interacts with it. The transmission is additionally equipped with a support bush, located from the side of the satellite and fixed on the driver shaft. Between the inner front surface of the body cover and the front surface of the flange of the bush rest its adjacency, also between the frontal surface of the satellite oriented flange, which is oblique, and the frontal surface of the satellite is located as an axial bearing. Between the teeth of the satellite and the toothed wheels are freely placed conical rollers, the number of which is equal to the number of the teeth of the satellite or the toothed wheels. The mechanism that prevents the rotation of the satellite around its axis, includes at least three balls uniformly located on the circumference, each being freely located in the housing executed on the lateral surface of the satellite, at the same time being placed in the longitudinal groove executed on the inner wall of the body. The transmission, according to the second variant, is characterized by the fact that it additionally includes a central gear wheel, fixed from the driving shaft position opposite the driven gear wheel, coaxially and interacts with the satellite, also contained by them, two support bushes, one of which it is fixed on the driver shaft, and the second, rigidly connected with it, is mounted in the gear wheel hub driven with the possibility of rotation against it. The front surfaces of the flanges of the support bushes, facing each other, are oblique and parallel. à
