Embodiment 1

[0036] A method for adjusting the inclination angle of the micro-slider of the above-mentioned measuring instrument is carried out as follows,

[0037] 1) Adjustment of the static inclination of the slider

[0038] The micro-slider 101 is fixedly connected to the crosshead 103, and under the action of a small force, the lower plane of the micro-slider 101 is in contact with the upper plane of the transparent disk 201, and the crosshead 103 makes the plane of the micro-slider and the plane of the disc automatically realize parallel surface contact state, the optical interference fringes formed by the lower plane of the micro-slider 101 and the upper plane of the transparent disc 201 can be easily observed in the optical interference system under the optical transparent disc 201 through slight disturbance, and the number of fringes represents the distance between the two surfaces. The size of the inclination. Using the adjusting screw 104 to fix the adjusting disc 102 can lock ...

Abstract

The invention discloses a miniature slipper bearing lubricant film measuring instrument which comprises a frame, a miniature sliding block, a transparent round disk, a miniature sliding block fixing and adjusting unit, a transparent round disk revolving unit, a loading single end and a micro-interference measuring unit, wherein, a group of adjusting devices are used for adjusting and fixing the obliquity of the miniature sliding block. The instrument achieves high efficiency and high accuracy in adjusting the obliquity, and height difference of the two sides of an inclined surface has an adjustment accuracy of 0.2 micron. The utilization of the instrument can lead to the obtaining of a determined obliquity between a miniature sliding block work plane and the transparent optical round disk in a static condition. The adjustment of the obliquity includes the adjustment of size and direction.

Description

technical field [0001] The invention belongs to the field of experimental measurement equipment for low secondary contact fluid lubricating oil film, in particular to a measuring instrument for measuring the thickness of fluid lubricating oil film under the condition that the inclination angle of the miniature sliding block bearing plane is constant. Background technique [0002] Oil film lubrication is an extremely important technical research field in engineering. It uses lubricating oil to form a separating oil film between two frictional solid surfaces to reduce surface wear. The experimental study of lubricating oil film mainly measures the thickness and shape of the oil film between a pair of friction surfaces. The two friction surfaces in oil film lubrication are divided into high pair contact (point contact, line contact) and low pair contact (surface contact) according to their contact mechanics characteristics. For point and line friction contact pairs, there are ...
