Embodiment Construction

[0020] Hereinafter, the configuration of an eccentric oscillating type reduction gear transmission according to an example of an embodiment of the present invention will be described with reference to the drawings.

[0021] figure 1 It is a sectional view showing the overall structure of an eccentric oscillating type reduction gear transmission according to an example of an embodiment of the present invention.

[0022] In this eccentric oscillating type reduction gear 10 , two eccentric bodies 12 make two external gears 14 internally mesh with an internal gear 16 while swinging, and output the relative rotation between the internal gear 16 and the external gear 14 as an output.

[0023] The input shaft 11 of the reduction gear transmission 10 is integrated with a motor shaft 18A of the motor 18 . An eccentric body shaft 24 is coupled to the input shaft 11 via a key 22 . The two eccentric bodies 12 are integrally formed on the eccentric body shaft 24 . The external gear 14 i...

Abstract

The invention provides an eccentrically swinging reducer device. According to the invention, when a supplying port for lubricant is formed in a cover component,lubrcant can smoothly flow to the reducer from the supplying port, so lubricant supplying time can be further shortened; the eccentrically swinging reducer device comprises an internal gear, an external gear, an eccentric body axis, a flange component, an inner pin, namely a pin component (32) connected to the flange component and passing through a through hole (14A) formed in the external gear,an inner roller component, namely a roller component (38) externally embedded nto the inner pin, and a first cover, namely a cover component (53) configured to an axial load opposite side of the external gear. A supplying port (70C) for lubricant, namely lubricating oil is formed in the first cover; a gasket (80) is configured betweeen the first cover and the inner roller; a gap (Delta 5) is axially arranged between the gasket and the external gear; the first cover is provided with protruding parts (74) limiting axial movemnts of the external gear; and the protruding part is circumferentially ararnged at intervals.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2014-001271 filed on January 7, 2014. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The invention relates to an eccentric swing type reduction gear. Background technique [0003] Patent Document 1 discloses an eccentric oscillating type reduction gear transmission. [0004] This reduction gear includes an internal gear, an external gear internally meshing with the internal gear, and an eccentric body shaft that eccentrically swings and rotates the external gear. A flange member is disposed on the axial load side of the external gear. A pin member penetrating through a through hole provided in the external gear is connected to the flange member. A roller member as a sliding promotion member with the external gear is fitted on the pin member. [0005] A cover member constituting a part of the casing of the reduction gear transmi...
