Embodiment Construction

[0030] Hereinafter, embodiments of the present invention will be explained in more detail with reference to the attached drawings.

[0031] According to the first embodiment of the present invention, the gear system (100) is a system that synthesizes characteristics of two drive units that are different from each other to produce various outputs. Such a gear system (100) can utilize changes in output characteristics in various fields as required according to circumstances. That is, through a gear system (100), the output of high speed-low torsion force or low speed-high torsion force can be changed into random shapes.

[0032] According to the first embodiment of the present invention, the gear system (100) includes a first gear part (110), a second gear part (120) and a third gear part (130). In particular, two of the gear parts serve as input means for outputting driving force, and the remaining one gear part serves as output means for outputting a resultant driving force. ...

Abstract

Disclosed are an epicyclic gear system using two input characteristics and generating a gear shifting effect using two motor characteristics, a gear module including the epicyclic gear system, and a control method of the epicyclic gear system. According to one embodiment of the present invention, the epicyclic gear system comprises: a first gear part; a second gear part rotatably engaging with the first gear part; a third gear part rotatably engaging with at least one of the first and second gear parts; and a driving source for generating driving force, wherein two of the first to third gear parts function as input parts, each of which receives a driving force from the driving source, and the other gear part functions as an output part to output the combination of the driving force from the two gear parts.; Accordingly, high speed / low torque or low speed / high torque can be selectively output according to the need via a combination of the two input characteristics, enabling a flexible change in the output characteristics even in a small robot.

Description

technical field [0001] A planetary gear system using two input characteristics, its gear mold and its control method are shown, and in more detail, a planetary gear system using two motor characteristics using two input characteristics with gear shifting effects is shown, Its gear mold and control method. Background technique [0002] In general, the selection of drive motors and reduction gear ratios is important when designing robots and mechanical systems. That is, after selecting the maximum speed and maximum torque for operating the robot and mechanical system, it is necessary to select a motor that matches it. However, as is the case with most mechanical systems, low speeds are used for driving (high torque) under heavy loads (loads), and high speeds are used for drives (low torque) under light loads (loads). For example, in the case of the movement of a human arm and the arm of a robot imitating a human, the movement of dancing (without lifting the weight) drives th...
