Abstract

A shot type gear ultrasonic shot peening strengthening device comprises an ultrasonic vibration device and a shot impact mechanism, the ultrasonic vibration device is composed of an ultrasonic generator, a transducer, an amplitude-change pole and a vibration head, the section of the working end of the vibration head is trapezoidal, and the vibration mode is radial vibration. The shot impact mechanism is composed of a shell, an upper cover plate, inner baffles, outer baffles and shots, a cavity in the same shape as the vibration head is formed in the shell, the contour shapes of the two sides, matched with a machined gear, of the shell are involutes, honeycomb-shaped orthohexagonal shot paths are arranged at the two sides of the shell, and inner baffle grooves are formed in the ends, close to the vibration head, of the shot paths; and outer baffle grooves are formed in the end, close to the machined gear, and a shot is installed in each shot path. According to the shot type gear ultrasonic shot peening strengthening device, the radial vibration generated by the vibration head is used for driving the shots to move in the shot paths and impact the surface of the gear, so that ultrasonic shot blasting is achieved, and the problem that because the distance between an ultrasonic tool head and the tooth surface of the machined gear is large, an ideal processing effect is difficult to achieve is solved.

Description

technical field [0001] The invention relates to the technical field of part surface strengthening equipment, in particular to a projectile-type ultrasonic shot peening device for surface strengthening of spur gears. Background technique [0002] Gears are widely used in mechanical transmission and power systems due to their reliable and stable transmission performance. Tooth surface wear is one of the most common faults in gear transmission systems. Wear usually occurs under conditions such as poor lubrication and harsh working conditions. Wear will lead to increased vibration and noise of gears, and in severe cases will lead to other faults of gears, such as Pitting corrosion, tooth surface peeling and even broken teeth not only reduce the accuracy of the transmission system, but also bring huge economic losses. [0003] Shot peening is a mechanical surface cold working method used to improve the fatigue strength of metal parts. The processing process is carried out at roo...
