Example Embodiment

[0013] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0014] like figure 1 As shown, the simple combined gear in the embodiment is mainly composed of three single-piece gears 1 of the same specification, and the three single-piece gears 1 are stacked in sequence and connected by riveting through cylindrical pins 2 .
[0015] like figure 1 As shown, the monolithic gear 1 in the present invention is a monolithic gear 1 obtained by a cold stamping die, and the disc surface of the monolithic gear 1 is provided with through holes uniformly arranged along the circumferential direction, and cylindrical pins 2 are arranged in the through holes. The three single-piece gears 1 are riveted together by a riveting machine. It is required that the height of the two ends of the riveted cylindrical pin 2 higher than the end face of the gear does not exceed 1mm.
[0016] The simple combined style gear of the present invention is suitable for occasions with low speed, small transmission power and low transmission precision, and can realize the transmission function of the gear. Compared with gear shaping and hobbing, stamping gear has high production efficiency, simple stamping equipment, low requirements for production operators' professional knowledge, saving processing time and cost, and maximizing the interests of production enterprises.
