Abstract

The invention discloses an engine balance shaft noise testing device. The device comprises a pedestal, a workbench, a guide rail, a balance shaft positioning tool, a balance shaft driving device, a balance shaft fixing device, a noise detecting device, an accompanied balance shaft and a hydraulic system, wherein the guide rail is arranged on the workbench; the balance shaft positioning tool is glidingly arranged on the guide rail; the hydraulic system is used for providing hydraulic oil with certain pressure and temperature to the balance shaft to be tested; the accompanied balance shaft is arranged below the balance shaft positioning tool; the balance shaft driving device is arranged in a box body on the right side of the workbench; the noise detecting device is arranged on the side wallon the inner side of the box body; an oil tank providing the hydraulic oil to the accompanied balance shaft is arranged at the position, corresponding to the noise detecting device, below the workbench; and the oil tank is connected with an oil tank lifting device. The engine balance shaft noise testing device is easy to operate and convenient to use, can conveniently and accurately test the performance of a balance shaft and has a great significance for improving the quality of balance shafts.

Description

technical field [0001] The invention relates to the field of mechanical testing, in particular to an engine balance shaft noise testing device for testing the performance of the balance shaft. Background technique [0002] During the working cycle of the engine, the piston moves very quickly and at a very uneven speed. At the top and bottom dead centers, the speed of the piston is zero, and at the middle of the top and bottom dead center the speed reaches the highest. Due to the repeated high-speed linear motion of the piston in the cylinder, a large inertial force must be generated on the piston, piston pin and connecting rod. The counterweight arranged on the connecting rod can effectively balance these inertial forces. However, only part of the moving mass of the counterweight on the connecting rod participates in linear motion, and the other part participates in rotation. Except for the upper and lower dead center positions, various inertial forces cannot be completely...
