Abstract

<P>PROBLEM TO BE SOLVED: To provide a rotation transmitting mechanism and a cylinder for a concentric rotor piston type internal combustion engine. <P>SOLUTION: The rotation of two rotors rotated at inconstant velocity is received by an eccentric rod deviant from a correlation type crank and a connecting wire, and a rotation shaft of a planet gear, and transmitted to one output arm and taken out to an output shaft by using the rotational angle velocity modulation of the eccentric rod obtained by planetary-rotating the planet gear in an internal gear frame with the three-times number of teeth, and moreover, the two rotors themselves are bound by one output arm and rotated periodically. A force in a reverse direction is received by a one-way clutch and passed off by bend of the connecting wire, and then, an explosive power is taken out as a rotational output as a structure not transmitted to the output side. Furthermore, a collisional mechanism is provided in a crank to prevent the occurrence of overcompression in a compression chamber when a piston is deflected from periodical rotational movement by the bend of the connecting wire. <P>COPYRIGHT: (C)2009,JPO&INPIT

２ローター６ピストン方式の機関に関しては、適切な回転伝達機構がないため実用化されていない。A 2-rotor 6-piston engine has not been put to practical use because there is no appropriate rotation transmission mechanism.

本発明は適切な機構を提供して振動、騒音を抑えコンパクトで効率が良く、かつ製作容易な内燃機関を実用化することを目的とする。It is an object of the present invention to provide an appropriate mechanism to put into practical use an internal combustion engine that suppresses vibration and noise, is compact, efficient, and easy to manufacture.

機関効率の高い分、冷却方法が課題である。The cooling method is a problem because of the high engine efficiency.

Means to solve the problem

出力アーム（９）に自転軸を有する遊星歯車（６−１、６−２）が歯数３倍の固定された内歯枠（１１）に噛合しながら出力軸（１０）の回転とともに遊星回転するとき、遊星歯車は出力軸１回転につき３回自転して、歯車の中心から一定の距離にある離心棒（７−１、７−２）は、角の円くなった正三角形の様な軌跡を描き、出力軸中心から見て周期的角速度変調回転する。The planetary gear (6-1, 6-2) having a rotation shaft on the output arm (9) meshes with the fixed internal tooth frame (11) having three times the number of teeth while rotating the output shaft (10) to rotate the planet. When this occurs, the planetary gear rotates three times per rotation of the output shaft, and the eccentric rods (7-1, 7-2) at a certain distance from the center of the gear are like equilateral triangles with rounded corners. A trajectory is drawn, and cyclic angular velocity modulation rotation is seen from the center of the output shaft.

離心棒（７−１、７−２）は連接ワイヤー（５−１、５−２）を介してクランク（４−１、４−２）に連接しローター（２−１、２−２）を前述の変調角速度回転させる。The eccentric rods (7-1, 7-2) are connected to the cranks (4-1, 4-2) via the connecting wires (5-1, 5-2) to connect the rotors (2-1, 2-2). The aforementioned modulation angular velocity is rotated.

２つのローター（２−１、２−２）の回転角速度変化は６つのピストン間の容積を変化させる。Changes in the rotational angular velocity of the two rotors (2-1, 2-2) change the volume between the six pistons.

離心棒（７−１、７−２）の位置を遊星歯車（６−１、６−２）の中心自転軸（８−１、８−２）から見て、等距離で同位相とするとき、ローター（２−１、２−２）は、出力軸（１０）と出力アーム（９）が６分の１回転するごとに、互いに他のロ−タ−の回転角度位置まで回転する周期回転をする。When the positions of the eccentric rods (7-1, 7-2) are equidistant and in phase when viewed from the center rotation axes (8-1, 8-2) of the planetary gears (6-1, 6-2). The rotors (2-1, 2-2) periodically rotate so that each time the output shaft (10) and the output arm (9) rotate by 1/6, the rotor rotates to the rotational angle position of the other rotor. do.

このローターの周期回転でおこるピストン（１ａ、１ｂ、１ｃ、１ｄ、１ｅ、１ｆ）間の空間容積変化を吸入、圧縮、爆発、排出及び冷却に利用するため、シリンダーの所定の位置に吸気口、排気口、冷気通気口、点火プラグ又は燃料噴射口を設ける。In order to use the space volume change between the pistons (1a, 1b, 1c, 1d, 1e, 1f) caused by the periodic rotation of the rotor for suction, compression, explosion, discharge and cooling, an intake port at a predetermined position of the cylinder, Provide an exhaust port, cold air vent, spark plug or fuel injection port.

屈曲することで、燃焼室後側ピストンにかかる逆回転向きの爆発力を出力軸に伝えないために連接ワイヤー（５−１、５−２）を設け、逆回転力を受け流すとともに、、ロ−タ−軸（３−１、３−２）に設けたワンウエイクラッチ（１２−１、１２−２）が、ピストン及びローターの逆回転を止める。By bending, the connecting wires (5-1, 5-2) are provided so as not to transmit the explosive force in the reverse rotation direction applied to the piston on the rear side of the combustion chamber to the output shaft. One-way clutches (12-1, 12-2) provided on the rotor shafts (3-1, 3-2) stop the reverse rotation of the piston and the rotor.

相関式クランク（４−１、４−２）は、一定角度で玉突き運動する玉突き部（１３−１、１３−２）を備え、吸入気が過圧縮となるのを防ぎ、燃焼室容積を確保する。Correlation cranks (4-1, 4-2) are provided with ball striking parts (13-1, 13-2) that perform ball striking movements at a fixed angle to prevent intake air from being overcompressed and to ensure combustion chamber volume. To do.
