The invention discloses a low-friction multivariable and adjustable load flywheel gear. An upper box body is connected with a lower box body to form an integral box body, the integral box body is filled with an oil liquid, and a main shaft is horizontally mounted in the integral box body in a penetrating manner and extends out of the box body; the main shaft adopts a stepped shaft structure, and a damping force simulated fan blade, a positioning sleeve, a first flywheel end cover, fix flywheels and a second flywheel end cover are sequentially mounted on the main shaft from the large end to the small end in a sleeving manner; first and second flying wheel coaxial components are arranged on both the first flywheel end cover and the second flywheel end cover, a brake mechanism is arranged below each flywheel, and multivariable and adjustable load can be achieved through the first and the second flywheel coaxial components and the brake mechanism. The low-friction multivariable and adjustable load flywheel gear provided by the invention achieves that the rotational inertia of the loaded flywheel is adjustable and the simulated load multivariate is adjustable, stepless adjustable rotational motion damping force within a certain range can be obtained, the frictional resistance is lowered, the volume is reduced greatly, the transportation is convenient, moreover, the running safety of a mechanical flywheel is improved.
Description
technical field [0001] The invention relates to a load simulation mechanism used in testing, in particular to a low-friction multi-variable adjustable load flywheel device. Background technique [0002] In the process of testing the industrial drive system, the performance of the drive system under different moments of inertia, different damping coefficients, and different driving forces has important indicative significance. Engineers improve the industrial drive system according to the test results under different conditions to obtain the system performance. best performance. During the test process, due to the need for many adjustment variables, the number of tests is large. If a flywheel is used as an inertial load, the inertial flywheel needs to be replaced every time the moment of inertia is adjusted, and the flywheel needs to be reinstalled using hoisting equipment, and the preparation time required for each adjustment of the moment of inertia is longer. The existin...
