Abstract

The invention discloses a device for measuring friction force and film thickness of a lubricating oil film under different surface speeds, and the device comprises an experiment bench which is provided with a translation platform, and the translation platform can move linearly under the drive of a drive device. A main shaft system is arranged on the experiment bench, a glass disc is arranged on the main shaft system, and the glass disc can rotate. An arc-shaped guide rail is arranged on the translation platform. The rotating base is installed on the arc-shaped guide rail and can move along thearc-shaped guide rail, the loading system is installed on the rotating base, a steel ball of the loading system and the glass disc move relatively, and a rotating bearing in the rotating base converts friction force generated by relative movement into pressure which can be collected by a pressure sensor on the rotating base.

Description

technical field

[0001] The invention discloses a device for measuring frictional force and film thickness of lubricating oil film with different surface speeds. Background technique

[0002] At present, the elastohydrodynamic lubrication test bench measures the oil film thickness and friction force of the ball-disc contact point in the same direction or in the opposite direction. Point and line contact are the contact methods of most ball bearings and some bevel gears. The movement direction of the contact surface in the actual working state is relatively complicated, such as hypoid gears and helical gears in the transmission system. The meshing contact pair The surface velocity directions of two contacting solids present a certain angle, and this contact motion direction is described as surface velocity anisotropy. For this more general condition where the velocities of two solid contact surfaces are different, the friction between the parts, the shape and thickness of the...
