Document Type and Number:
Japanese Patent JP2023114462
Kind Code:
A
Abstract:
To provide an eccentric oscillation type speed reducer capable of suppressing degradation of service life of an eccentric body to solve a problem on shortening the service life of the eccentric body due to a processing condition in a case where a grinding processing is performed on a surface of the eccentric body.SOLUTION: A residual stress at 20 μm from a surface of an eccentric body 12a is a compression stress, in an eccentric oscillation type speed reducer 10 including an internal tooth gear 16, an external tooth gear 14, and the eccentric body 12a for oscillating the external tooth gear 14.SELECTED DRAWING: Figure 1
