Title:
FRICTION PIECE IN LUBRICATED MEDIUM, WORKING AT CONTACT PRESSURES HIGHER THAN 200 MPa
Document Type and Number:
Japanese Patent JP2015148344
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prolong the existence of an elastohydrodynamic lubrication regime between a heavily loaded friction medium and lubricated friction parts.SOLUTION: A friction part in a lubricated medium working at contact pressures above 200 MPa has a surface that is textured and subjected, before or after the texturing, to a surface hardening treatment for a tribological function. The surface is subjected to operations for producing a periodic network of micrometric cavities having predefined shapes and sizes, with the period adapted to the width of the contact surface in order to promote passage to the elastohydrodynamic lubrication regime.
