my country is a big country in the manufacture and use of gears, but it is not a powerful country in gear manufacturing. The reason is that, in addition to the imperfection of gear processing technology, an important reason is that the gear detection technology is relatively backward, and it is impossible to make objective and correct judgments on the quality of the produced gears. Evaluation to guide processing and production

[0003] The traditional gear quality inspection method is to manually control the forward and reverse rotation of the tested gear on the machine tool by an experienced worker, and judge whether the gear is qualified by listening to the noise with the human ear and checking the contact spots with the human eye. This method is highly subjective. , susceptible to external interference, so it is impossible to comprehensively and objectively evaluate the quality and performance of the gear

At present, the commonly used gear quality inspection technologies and instruments include gear coordinate measurement center, single gear tester, double gear tester, and rolling inspection machine. These instruments have more or less the characteristics of single measurement parameters and low efficiency.

[0004] The mechanical power is transmitted through the force on the meshing line of the gear pair. Without the change of the force, there will be no vibration and noise. The traditional machine tool adopts the belt drive mode. Although this can isolate the vibration and noise of part of the driving motor, the belt The deformation and slippage of the tested gear will form an impact, while the use of gear transmission will introduce more unknown vibration and impact, which will reduce the dynamic performance of the machine tool, and the bad design of the tested gear, machining errors and grinding burns will cause wheel damage. Changes in tooth contact stiffness and fatigue strength will affect the stability of gear transmission, generate vibration, and emit noise
