    DESCRIPTION
    Procedure for distributed transmission of torque and angular velocity gear ratio (PI).
    Obieto v sector of the technique to which the invention refers
    The present invention relates to a method for a distributed transmission device of torque and angular velocity transmission.
    10
    More specifically, the device is of the type comprising a plurality of input shafts, an output shaft and an epicyclic or planetary gear; said gear being formed by a plurality of external or satellite gears, mounted on a mobile arm called a satellite carrier, which rotates on a central or planet gear and which also incorporates an external annular gear or crown that meshes with the satellites.
    It is of special application, although not exclusively, for the construction of drives based on electric motors, and of advantageous application in vehicles, normal and railway, that require autonomous electric network and batteries for 2 0 storage.
    The invention is located in the technical sector of electro-mechanical engineering, and more specifically in that related to electric drives.
    25 General and closest prior state of the art
    Most of the industrial drives of the state of the art are carried out by electric motors. The most robust, durable and least maintenance electric motor is the three-phase asynchronous squirrel cage motor, built with 4 30 6 2 poles.

    A three-phase asynchronous squirrel cage motor, for an electrical supply with a frequency of eg 50 Hz, will rotate with an angular speed (n) inversely proportional to the number of pairs of poles (p); eg for p = 1, n = 3,000 rpm; p = 2, n = 1,500 rpm.
    In the state of the art, machine shafts normally require smaller angular speeds, the use of a gear with a multiplier effect being necessary. An epicycloidal or planetary gear (30) is a gear system or train formed by one or more external gears or satellites (301) that rotate on a central or planet gear (302). Normally, satellites are mounted on a mobile arm called satellite carrier (303) which also allows them to rotate in relation to the central gear. These systems can also incorporate an external annular gear or crown (304), which meshes with the satellites (301).
    The invention recommends a method of distributed transmission of torque and angular velocity gear ratio (PI) carried out by means of a distributed transmission device of torque and angular gear ratio (1), formed by a plurality of electric motors (10 ' -10n) electrically powered in "series" connection and integrated in a novel way in an epicyclic or planetary gear (30).
    The "series" connection guarantees that the plurality of electric motors (10'-10n) will be fed with the same electric current intensity and that they will generate, even if there are disturbances, the same motor torque; preferably electric motors (10'-10n) are identical.
    A three-phase asynchronous electric motor of squirrel cage that allows a "series" connection is described in the patent application of the invention entitled "Asynchronous motor n-fasic squirrel cage", whose owner is the University of La Rioja.
    Various planetary epicyclic gears appear in the state of the closest technique (30); We have the following documents, among many others:
    In the patent document called D01 with publication number ES 1123331 U and filing date 05.09.2014 and literally entitled: "Continuous and reversible variable transmission", a variable, continuous and reversible transmission, composed of a speed variator, is described, mechanical or electrical or other, and a series 5 of epicyclic gears, which can be defined as a variable, infinitely continuous and reversible transmission.
    In the patent document called D02 with publication number ES 2504118 T3 and filing date 21.12.2012 and literally entitled: "Epicycloidal gear system 10", an epicycloidal gear system is described which can be used with advantage, although not exclusively , in the generation of wind energy, to transmit energy from the blades in the electricity generation system, and in the propulsion of aircraft, to transmit power from a turbomachine to the propulsion system.
    15 In the patent document called D03 with publication number ES 2426265 T3 and filing date 22.12.2010 and literally entitled: "Gear", an epicycloidal gear is described.
    Technical problem raised
