発明の名称 (英語) PLANETARY ROLLER DRIVE-TYPE INSCRIBED PLANETARY GEAR REDUCTION DEVICE
発明の概要(英語) [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).
特許請求の範囲(英語) [claim1]
1. The input axis which is connected by drive source, the shaft center turns to the center and,
In order for portion of the peripheral aspect and the surface of revolution of the aforementioned input axis to touch mutually, it provided, being parallel with the shaft center of the aforementioned input axis, identical direction the planetary roller which possesses the axis of rotation which faces and,
It consisted of with the outer ring which parallel from the periphery of the transmission board and the aforementioned transmission board of the disk condition which was formed vertically vis-a-vis the aforementioned input axis was formed to the aforementioned drive source side vis-a-vis the aforementioned input axis, in order to surround the center of the aforementioned transmission board, it possessed the plural perforation holes which were formed to regular interval in the aforementioned transmission board, portion of the surface of revolution of aforementioned planetary roller was inscribed to inside surface of aforementioned outer ring, the planet wheel where the internal tooth car was formed to the outer part surface of the aforementioned outer ring and,
The internal tooth car and the gearing which were formed to the outer part surface of the aforementioned outer ring of the aforementioned planet wheel the framework component which possesses the external tooth car which is done and,
The plural pins to which the plural perforation holes which were formed to the aforementioned transmission board of the aforementioned planet wheel are inscribed respectively at part stand facilities the aforementioned pin of the transmission board and the aforementioned transmission board which are done stand facilities on opposite side to the side which is done stand facilities the output axis which consists of the transmission axis which is done and,
The planetary roller drive type inscribed type epicycle reduction gear which features that it is constituted by.
[claim2]
