  • Publication number: 20060252595
    Abstract: In a rotation transmission device, a first planetary gear mechanism has a first gear, a second gear, a first planetary gear body, and a first carrier body. A second planetary gear mechanism has a third gear, a fourth gear, a second planetary gear body, and a second carrier body. The ratio of the pitch circle diameters of the third gear, fourth gears and second planetary gear body is the same as the ratio of the pitch circle diameters of the first gear, second gear, and first planetary gear body. The connecting element that is the first gear, second gear or first carrier body rotates integrally with an element corresponding to the connecting element.

  • Patent number: 5826483
    Abstract: In hydraulic heavy equipment, a working device has a boom, an arm and a bucket. An operating device has the same link structure as in the working device. By operating the working device, control valves are operated and the working device functions in a similar manner to the operating device. The movement of the working device is transmitted, and the control valves are brought back to the neutral position. Therefore, the working device follows up the operating device, and functions in the same manner as the operating device.
