The invention discloses a square crosspiece chain ring and a manufacturing method thereof. The square crosspiece chain ring comprises a chain ring and crosspieces, and the crosspieces are welded in the chain ring; matching cambered surfaces are symmetrically arranged at the two ends of the crosspieces and cover the inner ring of the chain ring, and welding stop grooves are formed in the connecting positions of the outer rings of the matching cambered surfaces and the chain ring. When square raw materials are adopted for machining, machining is convenient, clamping and positioning are convenient, the machined matching cambered surface are matched with the arc of the chain ring, the gear inclination phenomenon cannot be generated after gear pressing, and due to the fact that the welding stop grooves are formed in the crosspieces, the welding quality of the crosspieces is improved, and the bearing capacity of the chain ring is improved.
本发明公开了一种方型横档链环及其制造方法,包括链环、横档,所述链环内焊接有横档;所述横档两端对称设置有配合弧面,所述配合弧面包覆在链环内圈,所述配合弧面外圈与链环相连接处设置有焊档剖口。本发明采用方型原材料加工时,加工方便,便于装夹和定位,加工好的配合弧面与链环圆弧相吻合,压档后不会产生歪档现象,由于横档设置有焊档剖口,提高了横档的焊接质量,提高了链环承载能力。
