Abstract

[Problem] To provide a small-sized, lightweight, and inexpensive inscribed planetary gear reduction device that has lower levels of vibration and noise than in the prior art. [Solution] This inscribed planetary gear reduction device is configured from: a planetary roller (300) that turns while in contact with the outer peripheral surface of an input shaft (C); a planetary gear (400) having an outer ring (430) that turns with the outer periphery of the planetary roller (300) inscribed thereon; a frame member (500) having a fixed outer gear (533) capable of meshing with an inner gear (433) formed in the outside surface of the outer ring (430) and allowing the planetary gear (400) to move in planetary motion along the inner periphery; and an output shaft (600) capable of extracting and outputting only the revolution component from the motion of the planetary gear (400).

Description

technical field [0001] The present invention relates to a small and silent planetary roller drive type internal contact type planetary gear reducer, wherein the power transmission from the eccentric body connected to the input shaft of the internal contact type planetary gear reducer to the planetary gear uses planetary rollers instead of the eccentric body, and make the form of the planetary gear in such a way that the power transmission from the planetary rollers can be easily transmitted and the planetary gears can be used as a pressurization mechanism for the planetary rollers, so that the inscribed planetary A gear reduction device is integrated with the planetary rollers. Background technique [0002] Conventionally, in a mechanical device that transmits a driving force by rotating a main shaft of a driving source such as a motor, a speed reducer, a transmission, etc. are usually connected to the power from the driving source, and the rotational speed of the main shaft...
