Abstract

The invention discloses an ultrasonic grinding device for a gear. The ultrasonic grinding device comprises a rotary hollow shaft and a fixed base. The rotary hollow shaft is mounted in a penetrating hole in the fixed base in a sleeved mode, the rotary hollow shaft and the penetrating hole are rotationally connected, and one end of the rotary hollow shaft is fixedly connected with a connecting flange of an amplitude-change pole. A gear workpiece is fixed to the small end of the amplitude-change pole. The large end of the amplitude-change pole is located in the rotary hollow shaft and sequentially and fixedly connected with a vibration transmission pole, piezoelectric ceramic and an electrode slice. The piezoelectric ceramic and the electrode slice are connected with an ultrasonic generatorthrough an electric conduction mechanism. The other end of the rotary hollow shaft is connected with a rotary indexing device or a variable frequency motor. According to the ultrasonic grinding device, a gear ultrasonic vibration technology and a gear forming grinding technology are combined, ultrasonic grinding of the gear is achieved, the service life of a grinding wheel can be prolonged, the roughness of a tooth face is reduced, the machining precision of the gear is improved, the microscopic morphology of the tooth face is improved, and accordingly the anti-fatigue ability of the gear is improved.

Description

Technical field: [0001] The invention relates to gear precision machining equipment, in particular to a gear ultrasonic grinding device. Background technique: [0002] Gears play a decisive role in the system of transmitting motion and power. At present, the high-speed development of high-end equipment such as high-speed transportation, aerospace, and new energy requires more and more gears. Working under the conditions of high / low temperature and rain / sewage corrosion, at the same time bear the wheel-rail impact load generated by the line, the alternating load caused by the train's starting acceleration and braking deceleration, so more changes are made to the service performance and service life of the gear. High and even demanding requirements. Therefore, how to manufacture high-performance and long-life gears that serve under complex working conditions has become an important challenge for the innovation of mechanical equipment and the development of high-end equipment ...
