The invention discloses a non-circular section chain ring and a manufacturing method thereof. The non-circular section chain ring comprises ring crown parts and a straight body part, the ring crown parts are arranged on the two sides of the straight body part, and the section of the ring crown part and the section of the straight body part are arranged to be non-circular sections; each non-circular cross section comprises a circular ring with a hexagonal cross section, an elliptical ring with a hexagonal cross section, a circular ring with a rectangular cross section, an elliptical ring with a rectangular cross section, a circular ring with a trapezoidal cross section and an elliptical ring with a trapezoidal cross section. A special die with the non-circular section inner cavity is adopted for manufacturing the chain ring, operation and machining are convenient, the structure of the chain ring with the non-circular section is reasonable, the contact stress and the torsional freedom degree between the chain rings are reduced, winding and knotting of a long chain are avoided, and the working efficiency is improved.
本发明公开了一种非圆截面链环及其制造方法,包括环冠部位、直体部位,所述直体部位两侧设置有环冠部位,所述环冠部位和直体部位的截面设置为非圆截面;所述非圆截面包括六边形截面的圆环、六边形截面的椭圆环、矩形截面的圆环、矩形截面的椭圆环、梯形截面的圆环、梯形截面的椭圆环。本发明采用内腔为非圆截面专用模具制造链环,操作、加工方便,非圆截面链环结构合理,降低了链环与链环之间的接触应力和扭转自由度,避免了长链条缠绕、打结,提高了工作效率。
