Abstract

The invention provides a robot and a gear unit that can give a gearing a longer life. The robot is characterized in that the robot includes a first member, a second member provided rotatably with respect to the first member, a gearing that transmits drive power from one side to the other side of the first member and the second member, wherein, the gearing includes an internal gear, an external gear having a flexible barrel portion in a tubular shape with an opening portion in an end part, and rotating about a rotation axis relative to the internal gear, and a wave generator, the wave generatorincludes a cam having a non-circular outer circumferential surface, and a bearing including an inner ring, an outer ring, and a plurality of balls, the first member includes a counter body provided to face the end part on the opening portion side of the barrel portion, and a first seal member is provided between the outer ring and the counter body.

Description

technical field [0001] The invention relates to a robot and a gear unit. Background technique [0002] In a robot including a robot arm including at least one arm, the joints of the robot arm are driven, for example, by a motor. Generally, the driving force from the motor is decelerated by a speed reducer. As such a speed reducer, for example, a gear unit described in Patent Document 1 is known. [0003] The gear device described in Patent Document 1 includes: a rigid internal gear; a flexible external gear arranged inside the rigid internal gear; Move around. Here, a disc-shaped end plate is disposed facing the open end of the side where the external teeth of the flexible external gear are formed, and the front end side of the annular elastic seal attached to the open end of the flexible external gear and the inner side of the end plate The end surface contact is divided into a part on the outer peripheral side of the flexible external gear and a part on the inner periph...
