The utility model provides a bull gear for circulating type metal casting equipment, a gear ring and a gear ring frame, and aims to overcome the defects of high production cost and low efficiency due to the fact that a bull gear in the prior art is of an integral structure and the whole bull gear needs to be replaced after gear teeth are abraded. Comprising a gear ring and a gear ring frame, the gear ring and the gear ring frame are coaxially arranged and matched through end faces, and the gear ring and the gear ring frame are fixedly connected through a threaded connection device. The gear ring can be independently manufactured and machined and can be made of needed materials, the overall design of the gear is optimized, when local teeth are seriously abraded, the gear ring can be independently replaced, the overall gear does not need to be replaced, and the later maintenance cost is reduced. 本实用新型的目的在于针对现有技术大齿轮为整体式结构，当轮齿磨损后需更换整个大齿轮，使生产成本高、效率低的不足，提供一种循环式金属铸造设备用大齿轮、齿圈、齿圈架，本实用新型的一种循环式金属铸造设备用大齿轮，包括齿圈和齿圈架，所述齿圈与齿
