Description

Technical Field

[0001] This utility model relates to a measuring device, specifically a rotational friction force measuring device, which can be adapted to different types of test pieces to realize rotational friction force testing under different rotation conditions. Background Technology

[0002] The frictional characteristics of rotating components in military equipment directly affect the equipment's motion accuracy, reliability, and service life. Early measurement technologies were insufficient to meet the extreme operating conditions and high-precision requirements of military equipment, leading to the development of various targeted solutions.

[0003] To accurately measure the magnitude of rotational friction in rotating components, a rotational friction measuring device is used for analysis. Current rotational friction measuring devices can only provide a rough estimate and cannot accurately measure the magnitude of the rotational friction in the measured component, and they also have poor safety features. Summary of the Invention

[0004] To address the problem of difficulty in measuring the rotational friction force of the tested component, the purpose of this invention is to provide a novel rotational friction force measuring device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rotating friction force measuring device, including a shift fork base, a shift fork provided on the shift fork base, a tension gauge provided on the shift fork base, the tension gauge being connected to the shift fork via a connecting rod, the connecting rod having a columnar structure, one end of the connecting rod passing through a connecting hole provided on the shift fork, and the other end passing through a connecting hole provided on the tension gauge.

[0006] The shift fork has a Y-shaped structure, with a U-shaped rod at the long arm end and a columnar structure at the short arm end. The connecting hole on the shift fork is located at the tail end of the short arm end.

[0007] A rod cap is provided at one end of the connecting rod that passes through the connecting hole of the shift fork.

[0008] The tension gauge has a cuboid structure, with a tension sensor module at the top, which is columnar in shape.

[0009] The rotary friction force measuring device designed using the above-mentioned technical solution has the following advantages:

[0010] 1. The designed friction force measuring device has a simple structure, is easy to manufacture, and is easy to assemble;

[0011] 2. Capable of measuring the rotational friction of the workpiece under test;

[0012] 3. Different models of test parts can be tested by simply changing the shift fork, without the need to process special test fixtures, thus achieving reuse, improving the versatility of the deformation measurement device, and reducing costs;

[0013] 4. This solves the problem that current methods for measuring rotational friction can only roughly estimate the magnitude of rotational friction using simple methods, and the safety of such methods is poor. Attached Figure Description

[0017] The following description, in conjunction with the accompanying drawings, details a rotational friction force measuring device according to this utility model.

[0018] This utility model relates to a rotating friction force measuring device, see [link]. Figures 1 to 3 The system includes a shift fork base 2, on which a shift fork 1 is mounted. The shift fork 1 has a Y-shaped structure, with a U-shaped rod at the long arm end and a columnar structure at the short arm end. A force gauge 4 is mounted on the shift fork base 2. The force gauge 4 has a cuboid structure, with a force sensor module at its upper end, also in a columnar shape. The force gauge 4 is connected to the shift fork 1 via a connecting rod 3. The connecting rod 3 has a columnar structure, with one end inserted into a connecting hole in the shift fork 1 and the other end inserted into a connecting hole in the force gauge 4. The connecting hole on the shift fork 1 is located at the tail end of the short arm end, and a rod cap is provided at the end of the connecting rod 3 that inserts into the connecting hole.

[0019] During assembly, place the U-shaped rod side of the shift fork 1 into the rotating component to be tested, and position it into the shift fork base 2. Position the sensor end of the force gauge 4 upwards against the shift fork base 2. Connect the tail of the shift fork 1 and the force gauge sensor via the connecting rod 3. After installation, check that the shift fork 1 and the force gauge 4 are securely fastened. Since there is inherent friction between the shift fork 1 and the shift fork base 2, a fixed value can be set to ignore the influence of the force gauge 4 on the rotational friction detection results.

[0020] In use, a motor base 7 is set on the base plate 8, and a motor 6 is mounted on the motor base 7. The output end of the motor 6 is fitted with the test piece 5. The assembled shift fork base 2 is placed on the base plate 8, with the U-shaped rod side of the shift fork 1 facing the test piece 5. The sensor of the force gauge 4 is powered on, and the frictional force generated by the test piece is transmitted to the sensor of the force gauge 4 through the shift fork 1 and the connecting rod 3. After the rotational speed stabilizes, the test data of the sensor of the force gauge 4 is read.
