一种大型齿轮毛坯
摘要：
本实用新型公开了一种大型齿轮毛坯，包括锻造成型的齿圈(10)、能够与所述齿圈(10)的内侧壁相配合连接的铸造成型的轮毂(20)以及连接装置(30)；所述连接装置(30)设置在所述齿圈(10)与所述轮毂(20)配合后所形成的大型齿轮毛坯的两侧端面上，并且位于由所述齿圈(10)与所述轮毂(20)配合后而形成的呈圆形的缝隙处。上述大型齿轮毛坯，是由锻造成型的齿圈(10)与铸造成型的轮毂(20)相互连接而成，从而能够有效解决大型齿轮毛坯的质量问题。
摘要（英）：

The utility model discloses a large gear blank. The large gear blank comprises a gear ring (10), a hub (20) and connecting devices (30), wherein the gear ring (10) is formed through forging, and the hub (20) can be connected with the inner side wall of the gear ring (10) in a matched mode and is formed through casting. The connecting devices (30) are arranged on the end faces of the two sides of a large gear blank body formed after the gear ring (10) is matched with the hub (20) and are located in a round gap formed after the gear ring (10) is matched with the hub (20). The large gear blank is formed by connecting the gear ring (10) and the hub (20) formed through casting, and therefore the quality problem of the large gear blank can be effectively solved.
