Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2023148139
Kind Code:
A
Abstract:
To provide a power transmission device capable of suppressing speed unevenness of rotary motion output from one of a first motion member and a second motion member.SOLUTION: A power transmission device includes a first motion member having N pieces of first contact surfaces 42, and a second motion member having a plurality of second contact surfaces 46 contacting with the first contact surfaces 42. When one of high-speed rotary motion and low-speed rotary motion around different rotation centers is input, the first motion member and the second motion member can output by changing to the other motion due to contact with the first contact surface 42 and the second contact surfaces 46. The first contact surface 42 has as the whole a circular arc shape projecting to a radial outside relative to a line connecting adjacent apexes of an N square, and the second contact surface 46 has as the whole a linear shape. When a contact position with the center of the first contact surface 42 is the center of the second contact surface 46, at least one of the first contact surface 42 and the second contact surface 46 includes a protrusion 80 disposed in a position shifted from its own center.SELECTED DRAWING: Figure 7
