UNIVERSAL JOINT CROSS OF POWER TRANSMISSIONS AND A METHOD OF ITS HEAT TREATMENT |
| 摘要 |
A universal joint cross for power transmissions, said cross including a base having arms adapted to be engaged by bearing needles, said cross being made of a steel consisting essentially of 0.4 to 1.2 percent carbon and 0.1 to 0.3 percent manganese, the surface hardness of the arms at their points of contact with said bearing needles being in the range of 60 to 67 Rockwell C, and at the points near the base being in the range of 50 to 56 Rockwell C. The method of heat treatment comprises the steps of heating said cross to its hardening temperature, cooling said cross to obtain a hardened surface layer and then nonuniformly tempering said cross.
