ABSTRACT:
A forged gear for a transmission used in a motorcar, an agricultural machine, a construction machine or other industrial machine includes a gear body with spiral teeth and a dog member with dogs which is formed integrally with the gear body. Each dog has a body with a width which becomes greater in an axial direction of the gear and one end portion which is tapered in the same direction. Each dog projects both radially from an outer circumference of an annular portion of the dog member and axially from an inner side of one surface of an annular portion of the gear body. Only the spiral teeth of the gear body are formed and finished by machining, and all the other configurations and details of the gear, including the dogs of the dog member, are formed and finished only by forging a raw gear material. According to the preferred embodiment the foregoing inner side of one surface of the annular portion of the gear body is recessed as compared with an outer side of the same surface thereof.
