分析了摩擦压力机主螺母受力情况,确定了使用性能指标,并成功地研制了一种锌合金主螺母材料。其耐磨性优于ZQAl9-4、ZQSn6-6-3。在使用过程中尺寸稳定性和冲击疲劳性能良好。使用寿命和铜合金相比提高1倍以上,可取得明显的经济效益和社会效益。
The stress situation of the main nut of the friction press was analyzed, the performance index was determined, and a zinc alloy main nut material was successfully developed. Its wear resistance is better than ZQAl9-4, ZQSn6-6-3. Good dimensional stability and impact fatigue during use. Compared with copper alloy, the service life is more than double that of copper alloy, and obvious economic and social benefits can be obtained.
