Title:
CONTACT AREA STRUCTURE PRODUCT AND METHOD FOR FORMING CONTACT AREA STRUCTURE PRODUCT
Document Type and Number:
Japanese Patent JP2020056438
Kind Code:
A
Abstract:
To provide a contact area structure product capable of improving oil release degree without depending on base oil kinetic viscosity and worked penetration, to improve oil film formation capability and protective film formation capability, and reduce fretting wear, and a method for forming the contact area structure product.SOLUTION: A contact surface structure product relatively vibrates or minutely moves under grease lubrication. On at least one of a contact surfaces, a periodic structure of grating-shaped irregularities whose height continuously changes is formed, where convex vertices become non-flat surfaces. Moreover, a ratio (A/D) of an amplitude A of the vibration or minute movement to a contact width D in a minute movement direction is more than or equal to 1.SELECTED DRAWING: Figure 1
