WIRE POWER TRANSMISSION DEVICE HAVING DYNAMIC CHARACTERISTIC OF PLANETARY GEAR

摘要

PURPOSE: A wire power transmission device having a dynamic characteristic of a planetary gear is provided to obtain a power transmission characteristic of the planetary gear by a small number of pulleys and wires by combining hanging methods of wires wound around pulleys. CONSTITUTION: A wire power transmission device comprises a first rotating body(121) rotating by power input; a second rotating body(125) connected to a rotating shaft(141) of the first rotating body and fixed to a rotating shaft(145) rotating relatively to the first rotating body; third rotating bodies(123a,123b) to which wires(131,132) wound around the first and second rotating bodies are connected; and rotating frames(115L,115R) connecting the rotating shafts and the third rotating bodies to make the third rotating bodies revolve around the rotating shaft of the first rotating body and the rotating shaft of the second rotating body. The third rotating bodies transmit the rotational speed of the first rotating body to all over the second rotating body through acceleration and deceleration. One of the wire connecting the first and third rotating bodies and the wire connecting the second and third rotating bodies is connected by a crosswise hanging method and the other is connected by a rightly hanging method.
