摘　　要：为了研究深冷条件下轮毂轴承的疲劳寿命,以DAC407404040型汽车轮毂轴承为研究对象,采用深冷技术改善其热处理工艺,并在ABLT-1A型轴承疲劳寿命试验机上进行疲劳寿命强化试验,结果表明,该热处理工艺下的轮毂轴承达到要求,平均寿命达到39.537×106r。Aiming at studying the fatigue life of hub bearings under cryogenic treatment, DAC4074040 hub bearings were used as samples to improve the heat treatment with cryogenic treatment. The strengthen test was utilized to verify their fatigue life on ABLT-1A bearings fatigue life testing machines. The test re- sults indicate that the fatigue life of DAC4007040 hub bearing with cryogenic treatment meet the require- ment, which can run 39. 537 × 10^6r in average.
