Stainless Steel Spur Gears. For gear materials, SUS303 and SUS304 are most widely used. SUS304 is the most used stainless steel, but SUS303 has higher machinability. Including SUS303 and SUS304, the following materials for stainless steel spur gears are generally used. Austenite group stainless steel SUS303
Like spur gears, the normal gear ratio range for straight bevel gears is 3:2 to 5:1. 5. This engine is using a conjunction of hypoid gears and spiral bevel gears to operate the motor. Precision forging of spur gears with inside relief Oct 01, 1999 · Therefore, precision forging technology has been proposed for the forging of spur gears with alloy steel (SCM415) in this paper. The precision forging process can be seen in Fig. 2.This conceptual design can take advantage of the divided flow method 2, 3, 4, which can reduce tool pressure significantly while the billet fills the die cavity.The method developed includes two steps in the forging
