Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lubrication coefficient testing equipment, in particular to a lubrication coefficient testing equipment for lubricating oil. Background Art
[0002] The goal of lubricants is to reduce the coefficient of friction, making the movement between machine parts smoother and reducing wear. By forming a uniform and stable lubricating film, it acts as a buffer between metal surfaces, thereby reducing the friction caused by direct metal contact. The lubrication coefficient refers to the ratio of the force required to apply an external force between two contacting surfaces to the normal pressure. Excellent lubricants should be able to effectively reduce the friction coefficient between contacting surfaces and provide good protection and lubrication. When choosing a suitable lubricant, it is necessary to consider many factors such as working conditions, machine equipment requirements, and the use environment. For lubricants, the lubrication coefficient indicates the effect of the lubricant in reducing friction and wear. Existing testing equipment is often complex in structure and expensive. When consumers purchase, it is impossible to provide consumers with more intuitive test data, so the existing testing equipment can only be used in laboratories and cannot be used by users at sales terminals. Therefore, we have launched a lubricant lubrication coefficient test device. Utility Model Content

[0026] See also Figure 1-4 , the utility model provides a technical solution:
[0027] A lubricating oil lubricity coefficient testing device includes a workbench 1, the four corners of the lower end of the workbench 1 are fixedly connected to support legs 6, the front right end of the workbench 1 is fixedly connected to a collection box 7, the front upper end of the workbench 1 is fixedly connected to a flow testing device 5, a container 4 is placed in the middle of the upper end of the workbench 1, a rectangular support rod 2 is fixedly connected to the rear end of the upper end of the workbench 1, a viscometer 3 is movably connected to the outer surface of the rectangular support rod 2, and the viscometer 3 is located on the upper part of the container 4.
[0028] In this embodiment, the flow testing device 5 includes a test plate 51, and the front and rear parts of the lower end of the test plate 51 are fixedly connected to a No. 1 connecting block 53, and the ends of the two No. 1 connecting blocks 53 that are away from each other are movably connected to a No. 2 connecting block 54 through a rotating shaft, and the rear end of the No. 2 connecting block 54 located at the rear is fixedly connected to a protractor 52; the protractor 52 is located at the rear of the test plate 51, and there is no contact between the protractor 52 and the test plate 51; two partitions 511 are fixedly connected to the upper end of the test plate 51, and the two No. 2 connecting blocks 54 are fixedly connected to the upper end of the workbench 1; a placement cavity 11 is opened in the middle of the upper end of the workbench 1, and the container 4 is placed in the placement cavity 11.
[0029] Through the above solution: pour the lubricating liquid on the test plate 51, tilt the test plate 51, check the tilt angle of the test plate 51 through the protractor 52, and then observe the flow rate of the lubricating liquid on the test plate 51, so that consumers can measure the fluidity of the lubricating oil.
[0030] In this embodiment, a protrusion 32 is fixedly connected to the rear end of the viscometer 3, and a slide groove 31 is opened at the upper end of the protrusion 32.
