Description

Technical Field

[0001] This utility model relates to the field of torsion measuring disc technology, and in particular to a lubrication and sealing structure for a torsion measuring disc device. Background Technology

[0002] The torque measuring disc is a flange-type torque sensor that uses the reverse torque of a strain bridge testing device. It is stationary and does not rotate. The torque measuring disc serves as both a mounting support for the front and rear components and a deformable elastic element.

[0003] A patent with publication number CN118329253A discloses a starting torque measuring device for an aero-engine with a lubrication oil circuit. This patent includes a torque measuring disc, a steel sleeve with a sealed end face, an outer conduit, a steel sleeve, a first O-ring, a second O-ring, and a third O-ring. By using this torque measuring device between the aero-engine transmission housing and the starter motor, the starting torque of the transmission shaft can be measured without directly measuring it. This effectively solves problems such as limited installation space and vibration caused by high speeds in small aero-engines. The flexible connection between the oil inlet pipe, oil return pipe, and torque measuring disc eliminates the dispersion of starting torque by the lubrication oil circuit, solving the measurement accuracy problem. However, the following issues still exist in this patent:

[0004] During use, the aforementioned torsion measuring disc lacks a sealing structure between the oil inlet pipe and the torsion measuring disc, allowing oil and gas to enter the strain gauge mounting cavity along the threads, potentially posing a risk of oil and gas leakage. Furthermore, the return oil pipe is not designed with a circumferential anti-loosening structure, which may lead to loosening during disassembly and installation.

[0005] To address the above problems, a lubrication and sealing structure for the torsion measuring disc device needs to be designed to overcome these issues. Utility Model Content

The first outer protective cover 3 has a mounting groove 16. A set screw 10 is installed inside the mounting groove 16. A fourth O-ring 14 is provided between the set screw 10 and the first outer protective cover 3.

[0026] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the inner walls of the mounting groove 16 are respectively provided with sliding grooves 17 on both sides. A slider 20 is embedded in the inner wall of the sliding groove 17. A moving block 21 is provided on one side of the slider 20. A spring 19 is provided at one end of the moving block 21, and a retaining ball 18 is provided at one end of the spring 19. Two sets of set screws 10 are provided. A drive shaft 12 is provided in the middle of the torsion measuring disc body 1. The second outer protective cover 4 is fixedly installed between the torsion measuring disc body 1 and the torsion measuring disc body 1. The fuel injection pipe 5 is detachably installed between the torsion measuring disc body 1 and the torsion measuring disc body 1. The locking nut 7 is detachably installed between the torsion measuring disc body 1 and the torsion measuring pipe gasket 6 is detachably installed between the fuel injection pipe 5 and the fuel injection pipe gasket 6. The second O-ring seal 9 is connected to the fuel injection pipe... The pipes 5 are snapped together; the first O-ring seal 8 is snapped together with the oil injection pipe 5; the first outer protective cover 3 is fixedly installed with the torque measuring disc body 1; the middle protective cover 2 is detachably installed with the torque measuring disc body 1; the return oil pipe 11 is detachably installed with the torque measuring disc body 1; the set screw 10 is detachably installed with the return oil pipe 11; the fourth O-ring seal 14 is snapped together with the set screw 10; the moving block 21 is slidably connected with the slide groove 17; the slider 20 is fixedly connected with the moving block 21; the moving block 21 is fixedly connected with the spring 19; the spring 19 is fixedly connected with the retaining ball 18; and the retaining ball 18 is snapped together with the retaining groove 15.

[0027] Among them, the second O-ring 9 and the first O-ring 8 are sequentially fitted onto the right end of the fuel injection pipe 5, and after being inserted into the mounting hole of the torque measuring disc body 1, the left end is locked by the locking nut 7 and the fuel injection pipe gasket 6 to form a double sealing structure.
