Title:
APPARATUS FOR MEASURING FRICTION FORCE OF LUBRICANT
Document Type and Number:
WIPO Patent Application WO/2018/059105
Kind Code:
A1
Abstract:
An apparatus for measuring a friction force of a lubricant is provided, comprising: a mounting platform (10); a plate axle system (20), the plate axle system (20) being rotatably disposed on the mounting platform (10); a glass plate (30), the glass plate (30) being disposed on the plate axle system (20), and the plate axle system (20) driving the glass plate (30) to rotate; a column (40), the column (40) being provided with a sleeve (41) extending along an axial direction of the column (40), an outer wall of the sleeve (41) being provided with a lug (42), and the column (40) being disposed opposite to the glass plate (30); a ball axle system (50), the ball axle system (50) being connected to the sleeve (41), the ball axle system (50) comprising a ball axle (52) and a ball axle driving assembly (51) driving the ball axle (52) to rotate, one end of the ball axle (52) being disposed inside the ball axle driving assembly (51), an end portion of the other end of the ball axle (52) being provided with a steel ball (53), the steel ball (53) being in contact with an upper surface of the glass plate (30), and a horizontal distance from the lug (42) to a central axis of the column (40) being greater than a horizontal distance from the steel ball (53) to the central axis of the column (40); and a force measuring system (60), the force measuring system (60) being in contact with a side wall of the lug (42) and used to measure the friction force of a lubricant. The apparatus for measuring friction force of a lubricant of the present invention has high measuring accuracy.
