Description

Technical Field

[0001] The invention mainly relates to the technical field of gear oil wear spot testing, and specifically to a Fischer-Tropsch synthesis long-mileage vehicle gear oil wear spot testing structure and method. Background Art

[0002] Gear oil wear spot test is an experimental method used to evaluate the anti-wear performance of lubricating oil. It is mainly carried out by the four-ball method. The four-ball method test on gear oil in different states can more fully reflect the performance of gear oil. Gear oil in different states can be obtained by changing the wear particles, mixed air volume and mixed water volume in the gear oil.

[0003] In the four-ball method test, three of the steel balls are firmly placed in an oil box and immersed in the test oil. Another steel ball of the same diameter is placed on top of the three balls, and a specified load is applied to make the top ball form a "three-point contact" with the three lower steel balls in the oil box. When the test oil reaches the specified test temperature, the top ball rotates at a specified speed for 60 minutes before the test ends. Then the wear spot diameters of the three lower steel balls are measured, and the average value is taken to evaluate the anti-wear performance of the lubricant.

[0004] The existing four-ball friction testing machine needs to post-process the steel balls after a single four-ball test before the next test can be performed, which is not convenient for continuous testing of gear oils under different conditions. Summary of the invention

The motor drives The movable turntable 12 moves the three-ball fixing device 20 after the friction processing is completed to the detection station, and the wear spots of the detection balls 24 in the three-ball fixing device 20 are observed and measured by a microscope. The motor drives the turntable 12 to move the observed three-ball fixing device 20 to the three-ball cleaning device 50, and the three-ball cleaning device 50 cleans the three-ball fixing device 20.

When preparing the gear oil mixed with liquid, quantitative liquid can be added through the liquid addition pipe 44, and quantitative solid can be added through the solid addition pipe 43 when preparing the gear oil containing mixed wear particles. When preparing the gear oil containing bubbles, the gas source system connected to the gas addition pipe 47 is opened, and gas can be added through the gas addition pipe 47.

The waste liquid after flushing is discharged through the backwashing drain pipe 46 after the valve is opened;

[0067] When the ball-pushing driver 30 is working, the actuator end of the power cylinder at the bottom of the top plate 11 drives the motor to descend until the ball-pushing at the actuator end of the motor contacts the detection ball 24, and the actuator end of the motor drives the ball-pushing to rotate, and friction between the ball-pushing and the detection ball 24 begins;

[0068] When the three-ball cleaning device 50 is working, the actuator end of the electric cylinder 51 drives the positioning cover 52 to descend until the positioning cover 52 covers the top of the positioning tube 21, and the water inlet pipe 53 is connected to the water source system for water supply, and the water flow flushes the positioning tube 21, and the waste liquid is discharged through the drain pipe 54;
