Abstract

The invention provides a brake mechanism and a speed reduction mechanism. This speed reduction mechanism is provided with: a speed reduction unit that reduces an input rotational speed; a speed increasing unit that increases the rotational speed output from the speed reducing unit; and a brake unit that applies a braking force for braking the speed increasing unit.

Description

technical field [0001] The present invention relates to a brake mechanism and a deceleration mechanism, and particularly relates to a technology suitable for use in a mechanism equipped with a brake and a decelerator. Background technique [0002] In industrial robots, machine tools, etc., it is dangerous if they cannot maintain their posture and hang down due to their own weight when they stop due to some abnormality such as emergency stop or power failure. Therefore, in general, a robot or the like is provided with a brake for maintaining the posture. [0003] As such an example, as described in Patent Document 1, it is known that the drive unit 10 provided in the first articulated body 3 of the robot 1 has the following components: a motor 20; Shaft 29 is arranged in parallel; Pulley mechanism 40, it connects output shaft 29 and one end 25a of brake shaft 25 and transmits the rotation of motor 20 to brake shaft 25; And electromagnetic brake 21 and speed reducer 22, it an...
