Description
Technical Field
The invention relates to a flexible transmission ultrasonic tooth surface rolling cutter.
Background
High performance is always the target pursued by heavy-duty gears, and mainly takes high power density, long service life, stability and low noise as main evaluation indexes. The high-performance gear should have excellent high-temperature service performance, high bearing capacity, high fatigue resistance and reliable severe working condition adaptability. The high-performance gear needs to bear extremely large load during working, so that the tooth surface of the heavy-duty gear has the characteristics of high strength and high wear resistance.
It has been found that conventional rolling is largely classified into planar type part processing and cylindrical type part processing. At present, the rolling machining of the plane parts is mainly realized by clamping a rolling tool bit on a main shaft of a machine tool and through the rotation movement of the rolling tool bit and the feeding movement of a workpiece in a machining plane. When the traditional rolling cutter is used for processing the surface with the gear tooth surface, the phenomenon that the processed surface is uneven and the surface finish is damaged can be caused because the cutter head balls cannot be fully contacted with the processed surface due to the surface roughness, and the phenomenon that the rolling track is dense can occur in part of the area, so that the thermal deformation occurs in the area, and the traditional rolling cutter has great limitation on the cambered surface processing. Ultrasonic rolling is a composite machining mode of adding ultrasonic high-frequency vibration to the traditional machining technology as one of special machining technologies, so that corresponding machining effects are improved.
