Title:
ROTATIONAL SHAFT REINFORCEMENT STRUCTURE AND GEARED MOTOR
Document Type and Number:
Japanese Patent JP2019027552
Kind Code:
A
Abstract:
To provide a rotational shaft reinforcement structure capable of improving durability of a rotational shaft without increasing the size of a device.SOLUTION: A rotational shaft reinforcement structure 60 is applied to reinforce an output shaft 13 rotatably supported to a bearing 22A. The rotational shaft reinforcement structure 60 comprises a reinforcement member 62 contacting with an outer peripheral edge 14A of an end surface 14 on a +Z direction side of the output shaft 13, and a spring 65 configured to energize the reinforcement member 62 to the output shaft 13. When the output shaft 13 slidably rotates to the bearing 22A and the output shaft 13 wears, the reinforcement member 62 is inserted into a gap G generated between the bearing 22A and the worn output shaft 13, with energization from the spring 65.SELECTED DRAWING: Figure 5
