Toothed sprocket shaft surface on both sides of a circular arc, sprockets material in order to link the entry and exit engagement. When the tooth using standard tooling, stainless steel sprocket material, working drawings are not necessarily drawn on the end face of the sprocket tooth, sprocket materials, but must draw the toothed sprocket shaft surface for turning sprocket bad hair. Specific shaft surface tooth see design manual. Sprocket should have sufficient contact strength and wear resistance, it more heat-treated tooth surface. Engaging the large number of small sprocket wheel more than, suffered the impact is large, so the materials generally should be better than the large sprocket. Common carbon steel sprocket materials (such as Q235, Q275,45, ZG310-570 etc.), gray cast iron (eg HT200) and the like. Steel sprocket can be important. General principles of choice sprocket teeth: 19 tooth sprocket or more generally run for high speed, normal working conditions. 17 tooth sprocket is used only for a small pitch. 23 teeth or 23 teeth had recommended for the case of an impact. When the ratio is low, with a high number of teeth of the sprocket can greatly reduce the amount of rotation i links, tensile load and load bearing chains.
