Beschreibung
Zusammenfassung:	The invention discloses a transmission output shaft heat treatment strengthening process and a transmission output shaft, and belongs to the technical field of transmission machining. The transmissionoutput shaft is made of low-carbon alloy steel. The transmission output shaft heat treatment strengthening process comprises the steps that S1, carburizing and quenching and low-temperature temperingtreatment are conducted on the transmission output shaft; and S2, induction heating and secondary quenching treatment are conducted on a spline section. By means of the characteristics that the induction heating speed is high and the spray cooling capacity is high, the surface hardness of the spline section can reach 58HRC-64HRC, and the effective hardened layer depth reaches DS450HV54.5-6.5. Compared with the prior art, the strength of the subsurface layer of the transmission output shaft can be improved, the hardness decreasing gradient is reduced, and the torsional strength of the transmission output shaft is impro
