Ultrasonic-assisted radial gear rolling forming device

Abstract

The invention provides an ultrasonic-assisted radial gear rolling forming device which mainly solves the problems that radial rolling force is large and rollers are abraded soon and are short in service life. The ultrasonic-assisted radial gear rolling forming device is composed of a motor (1), a belt (2), a belt pulley (3), transmission shafts (4), radial feeding hydraulic cylinders (5), transducers (6), waveguide rods (7), the rollers (8), a gear blank (9), an electromagnetic induction coil (10), a center device (11), a feeding hydraulic cylinder (12), ultrasonic generators (13), roller supports (14), worms (15), an electromagnetic heating controller (16), a driving shaft (17) and worm gears (18). The waveguide rods (7) of an ultrasonic vibration system are connected with the roller supports (14) through screw rods in a pre-tightening mode. According to the materials of gear blanks and different forming modes, whether the gear blank is heated, the magnitude of alternating currents and ultrasonic vibration frequencies are decided, and radial ultrasonic precision rolling forming of gears is achieved in a roller rolling mode; according to the ultrasonic-assisted radial gear rolling forming device, rolling force is effectively reduced, the service life of the rollers is prolonged, the surface roughness of gear teeth can be lowered, and machining efficiency is improved.
