“…Resonant frequency in the test and designing frequency have a relatively smaller deviation, which is only 5.7%. Experimental frequency is lower than the theoretical calculation frequency, this situation is also mentioned in document [7], the reasons may be that the theoretical calculation is based on an idealized model.…”

In the machining of ultrasonic gear honing, gear’s dynamic characteristics have a significant impact on the designing of vibration system and machining quality of gear. Since the gear and solid horn produce resonance, it is necessary to give a comprehensive consideration of the interaction between the two. This paper utilized the boundary conditions of the plate and the horn at the connection surface and their own dynamical equations to establish dynamical model of composite structure of the gear and the horn, which providing a theoretical basis for the horn designing and the gear’s dynamic characteristics analysis in ultrasonic gear honing. The results of calculation example are consistent with that of test, it verifies that the proposed analytical method in this paper is feasible.

In recent years, ultrasonic-assisted machining (UAM) has been widely implemented to improve the performance and element quality of machined products. This paper comprehensively reviews the ultrasonic vibration effects on such ultrasonic vibration-assisted (UVA) processes as hobbing (UVAH), lapping (UVAL), electrochemical gear machining (UVAEGM), honing (UVAH), and grinding (UVAG), respectively. Compared with the conventional machining, the UAM significantly reduced the surface roughness, improved the surface microstructure, and quality. Considering the UAM applications surface modification and surface strengthening, the available technologies of ultrasonic impact, ultrasonic shot peening, and ultrasonic deep rolling were analyzed for gears and similar components. It was concluded that the surface was strengthened under UAM through introducing the high-amplitude and large-depth residual compressive stresses, restraining crack propagation to a certain extent, and improving the gear fatigue resistance. Finally, the ultrasonic machining effect on gear fatigue resistance was theoretically substantiated from the ultrasonic vibration system and surface integrity standpoints. This review aims to optimize the application of ultrasonic-assisted machining, in order to produce gears with enhanced fatigue resistance and surface integrity.

“…Compared with the conventional machining, ultrasonic machining is beneficial to reduce the cutting force [4], extend tool life [5], enhance machining accuracy [6], improve workpiece surface morphology [7] and increase workpiece wear resistance [8] and corrosion resistance [9]. Thus, the ultrasonic vibration as a novel processing was combined with the conventional gear machining, and some ultrasonic gear machining was developed at home and abroad, such as the ultrasonic vibration-assisted hobbing gear, shaving gear [10], lapping gear [11], honing gear [12] and ultrasonic electrochemical machining gear [13]. Taking the state-of-the-art relevant publications into consideration, the ultrasonic vibration-assisted machining gear could improve the processing technology and manufacturing process, and bring significant variation to the surface integrity and fatigue performance [14].…”

Gear plays an important role in transmitting motion and power system, and a new promising process should be utilized to enhance the machining accuracy and performance. In this paper, the ultrasonic vibration was superimposed into the gear to carry out the tangential ultrasonic vibration-assisted grinding gear (TUVAGG). The longitudinal resonant vibration system was designed based on the non-resonant theory. Firstly, the gear was simplified into a disc with the diameter of the reference circle, and the dynamic equation of each part was erected respectively.Then the frequency equation was derived according to the coupling conditions of the force and displacement during the combined surface of the vibration system. Simultaneously, the characteristic of displacement for the vibration system was also obtained. Secondly, the vibration system composed of the simplified disc and the gear was simulated by the finite elements analysis method, and verified by the resonant measurement experiment respectively. The measurement results exhibited a good agreement with the theoretical. Finally, the effectiveness of the vibration system was verified through the ultrasonic vibration-assisted grinding gear test. It was found that compared with the conventional grinding gear (CGG), the normal grinding force and tangential grinding force was reduced by 7.4-28.2% and 8.9-18.9% respectively during TUVAGG. Besides, the grinding temperature and the surface roughness was declined by 7.6-25.7% and 8.6-21.8% respectively, and the residual compressive stress of tooth surface was elevated by 13.2-29.3%. It was concluded that the non-resonant theory was suitable for the designation of longitudinal vibration system for TUVAGG, and also provided a novel process technology for gear machining.
