Adjustable speed sensor performance testing device

The utility model discloses an adjustable speed sensor performance testing device, which solves the problem of speed sensor rotating speed testing, is suitable for performance testing of a speed sensor, and can be matched with different environment test boxes at the same time. And the mechanical stresses such as a high-low temperature damp-heat test box, a high-low temperature impact test box and a mechanical stress such as a vibration table and a mechanical impact table can be simulated, so that the speed sensor can be simulated under different environmental stress working conditions, and the reliability of the speed sensor can be effectively verified. By replacing the size of the gear, the plug-in can be matched with speed sensors with different rotating speeds and different sizes and types, only the plug-in needs to be connected with the speed sensors, the operation is simple, the test cost is effectively saved, and the test efficiency is improved.
