PURPOSE:To make a large capacity power smoothly transmittable by providing cylinders on the sides of No.1-No.3 planetary gears and further providing annular bodies which circumscribe the cylinders on the opposing sides of a adjacent planetary gears. CONSTITUTION:On the sides of No.1-No.3 planetary gears 4, 9, 10, cylinders 13-18 are provided each concentrically to the respective planetary gear centers and on the opposing sides of adjacent planetary gears annular bodies are provided such as an annular body 19 which circumscribes the cylinders 16 and 13 and an annular body 20 which circumscribes the cylinders 14 and 17. The centrifugal forces acting on the No.1-No.3 planetary gears 4, 9, 10 and eccentric cylinders 23, 24 are balanced with each other through the annular bodies 19, 20, 25 and 26. By this arrangement the increase of the tooth face load and bearing load due to the centrifugal forces is prevented, allowing smooth rotation of the gears under a high speed and heavy load. |
