Abstract

The invention discloses a method of testing a dynamic meshing force of a gear. The method comprises the following steps: the rotational inertia of an angular acceleration transducer and the rotational inertia of the gear are measured and calculated; the angular acceleration transducer is arranged and adjusted at the output shaft of a gear box, and the angular acceleration of the output-end gear is measured; after the angular acceleration transducer, a torque sensor is arranged and adjusted, and the output-end torque of the gear box is measured; and in combination of the basic circle radius and the rotational inertia of an output-end driven gear of the gear box, the rotational inertia of the angular acceleration transducer, the angular acceleration of the output-end gear of the gear box and the output-end torque of the gear box, the dynamic meshing force of the gear is calculated and obtained. Through the above mode, test on the dynamic meshing force of the gear is realized, and reliable experimental data for the study of vibration noise and fault diagnosis of gear system are provided.
