The application provides a power generation device and a flywheel temperature measurement system of the engine. The power generation device includes a permanent magnet and a coil winding. The permanent magnet is arranged on the flywheel housing of the engine. The coil winding is arranged on the flywheel of the engine. When the flywheel generates relative motion, it cuts the magnetic force lines of the permanent magnet to generate current, which supplies power for the flywheel temperature measuring device. In the power generating device provided by the present application, since the coil windings are evenly distributed on the flywheel and the weight is relatively light, it will not affect the motion balance and moment of inertia of the flywheel, and because the coil windings will only generate relative motion between the flywheel and the flywheel The current is generated by cutting the magnetic field lines of the permanent magnet, that is, the power generation device will only generate power when the engine is running, and will not generate power when the engine is stopped. The test will fail because the battery power is exhausted due to the long storage time.
Description
technical field [0001] The invention relates to the technical field of flywheel temperature measurement of an engine, in particular to a power generation device and a flywheel temperature measurement system of an engine. Background technique [0002] When the engine flywheel is tested for temperature and stress, because it is a high-speed rotating part, it cannot power the temperature acquisition system directly installed on the moving part. The existing solution is to use the internal power supply of the battery. For the internal power supply scheme of the battery, the weight of the battery is large, which will affect the dynamic balance of the moving parts, and the power supply capacity is limited. After the installation is completed, the test must be carried out in a short time. SUMMARY OF THE INVENTION [0003] In view of this, the present invention provides a power generation device and a flywheel temperature measurement system for an engine to solve the problems exi...
