Embodiment Construction

[0022] Hereinafter, the configuration of a gear device series according to an example of an embodiment of the present invention will be described in detail with reference to the drawings.

[0023] Starting from the outline, the gear unit series of the present invention includes, as its constituent elements, a first gear unit and a second gear unit in which the internal teeth of the internal gear are formed of pin members.

[0024] Since the first gear unit and the second gear unit have the same structure except for the structure around the internal gear, first, the overall structure of the first gear unit will be described here, and then, focus on the first gear unit and the second gear unit. 2 The difference of the gear unit will be explained.

[0025] figure 1 It is a sectional view showing the overall structure of the first gear unit 110 of the gear unit series according to an example of the embodiment of the present invention, figure 2 is along figure 1 Partial enlar...

Abstract

The present invention can provide a lower cost to constitute the low reduction ratio high reduction ratio gear unit series gear means comprising a first gear and a second gear unit means, first gear means and second gear means includes: an internal gear, having the gear body and a plurality of pins arranged in the main body of the internal gear member and the inner teeth constituted by a pin member; cover member, the internal gear connected to the main body, wherein the first gear and the second gear means means common cover member, the cover member is provided with a holding tank, the second gear means having means more than the first pin member gear, and the diameter of the pin member is smaller. Body side of the internal gear device having a first gear holding pin member axial part of the entire circumference of the retaining hole, the pin member of the first gear unit is not held in the holding tank cover member, but remains the subject of internal gear retaining hole . In the body of the second gear means is not provided with the gear member retaining pin hole, the second pin member held in the gear unit holding tank cover member.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2013-223768 filed on October 28, 2013. All the content of this Japanese application is incorporated in this specification by reference. technical field [0002] The invention relates to a series of gear units. Background technique [0003] Patent Document 1 discloses an eccentric oscillating gear device in which an external gear meshes with an internal gear while oscillating, and outputs the relative rotation between the external gear and the internal gear as a deceleration output. [0004] The internal gear in this gear device includes an internal gear main body and a plurality of pin members disposed on the internal gear main body, and the pin members constitute internal teeth of the internal gear. [0005] A holding hole for holding the pin member is provided in the internal gear main body, and the pin member is held in the internal gear main body in a state in which a part of the side surfa...
