Latest Patents

Goldsberry's patent, titled "Method for Producing a Planetary Gear Shaft Having Increased Hardness," outlines a comprehensive method for hardening planetary gear shafts. This process involves carbonitriding the outer peripheral surface of the shaft and subsequently quenching it in oil at a temperature between 120 and 150°C. Furthermore, the methodology includes quenching the shaft in a liquid at temperatures ranging from -70 to -120°C and tempering the shaft to achieve superior hardness. After the tempering process, the outer surface of the planetary gear shaft exhibits a hardness of HV 832 or more, while maintaining a material hardness of at least HV 513 to a depth of 0.5 mm. Additionally, high-temperature tempering and induction hardening steps can be incorporated to produce soft ends of the shaft, allowing for effective staking operations.
