FIELD: mechanical engineering. ^ SUBSTANCE: friction unit comprises contacting friction surfaces (1) and lubricating agent (4). Lubricating agent (4) comprises fillers made of microscopic particles having regular spherical shape. At least one of the contacting friction surfaces (1) is provided with the microscopic profile with hollows (2) made of grooves. The radius of spherical friction particles (3) exceed the depth of hollows (2), but no more than by a factor of two. ^ EFFECT: enhanced efficiency. ^ 1 dwg |
