Figure 3 is a structure of four common sprocket. Small sprockets generally made integral (Figure 3a), conveyor chain sprocket material, intermediate diameter sprocket made more radiation plate, for ease of handling, chucking and weight loss, the spokes opening (Fig. 3b) , can be made modular larger diameter sprocket (Fig. 3d), and at this time the ring gear wheel core manufactured using different materials! For example C45, stainless steel and other materials. 1. Figure 1 sprocket tooth chain sprocket tooth must ensure that energy-smooth freely enter and exit the engagement to minimize the impact and contact stress mers engagement, but also to ease of processing. Conventional sprocket tooth end face in Figure 1. It is composed of three arcs aa, ab, cd and bc some linear structure, drive sprocket material, referred to three arc - straight teeth. Tooth using standard tooling, the figures are not necessarily drawn to work on the end face of the sprocket tooth, simply stated 'tooth by 3RGB1244-85 specified by the manufacturer' to the sprocket material drawing in the figure, but it should draw sprocket axial tooth, Jinzhou City sprocket material, shown in Figure 2, the size refer to the design manual. Front parameter calculation already mentioned, not repeat the narrative! Drive sprocket material advantages of the brand beyond the network chain (certification), Changyi sprocket material supplied by factory Ningjin beyond network chain. Ningjin beyond network chain factory (www.njcywl.com) is Dezhou, conveyor leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Beyond the network chain leadership with the staff warmly welcome all inquiries negotiations to create network chain beyond a better future.
