The large ring gear is one of the commonly used mechanical parts through which the direction of the force is transmitted and changed. It belongs to thin-walled ring forgings. In the forging process, problems such as uneven wall thickness, folding, ellipse, etc. are easy to occur, and the quality of forgings can be improved by controlling the details of the forging process.
The alloy is made of 35CrMoPb, the initial forging temperature is 1220 °C, the final forging temperature is 750 °C, and the precision forging temperature is 700 °C.
