Abstract

The invention belongs to the technical field of rotational inertia measurement, and in particular relates to a rotational inertia measurement device and a measurement method. The moment of inertia measuring device in the present invention includes a first fixing component, a main shaft, a measuring weight, a bearing component and a second fixing component. One side of the first fixing component is used to fix the rotor shaft of the motor, and one end of the main shaft is connected to the rotor shaft of the motor. The other side of the first fixing assembly is connected, the other end of the main shaft is provided with a hook, the measurement weight is wound on the main shaft through a connecting rope and hung on the hook, the measurement weight is In the process of free fall, the main shaft, the first fixing assembly and the motor rotor are driven to rotate, the main shaft is penetrated inside the bearing assembly, and one side of the second fixing assembly is used for fixing The motor stator, the other side of the second fixing assembly is connected with the bearing assembly through the adjusting assembly.

Description

technical field [0001] The invention belongs to the technical field of rotational inertia measurement, and in particular relates to a rotational inertia measurement device and a measurement method. Background technique [0002] In the development of diesel engines for mining trucks and power generation, the motors used with the whole vehicle are all used by the original vehicle, and their moment of inertia cannot be obtained. One of the input values ​​for calculation, the inaccurate value of the moment of inertia will cause the crankshaft calculation to fail, and there will be a crankshaft fault when matching the vehicle subsequently. However, in the research and development process of the existing diesel engine, the rotor is removed and the rotor is measured or the three-dimensional model of the rotor is measured by three-dimensional software. It is difficult to handle and measure the situation where the rotational inertia of the matching motor is unknown and the rotor cann...
