机锤喷丸（MHP）是一种用于表面处理的高频渐进成形工艺，用于铣床。由于与锤头的气动和电气连接导致电机主轴固定，因此可能会发生点负载，并可能在主轴轴承环上引发假性布氏磨损。这项工作的目的是对主轴适配器和轴承上的 MHP 反作用力之间的相互依赖性以及 MHP 期间主轴轴承环的相关假布氏磨损进行实验和数值分析。首先，对高刚度伺服机械压力机上的 MHP 反作用力随频率、电力和时间的变化进行了测量。其次，通过疲劳试验和数值有限元软件Abaqus 6.14和NewSpiladandWinLager软件的补充模拟，对MHP期间的主轴轴承磨损进行了分析。第三，通过轴承耐久性测试系统分析了损坏的主轴轴承对铣削操作的影响。结果表明，铣床 MHP 期间，主轴轴承环上的假布氏磨损发生在 fmhp= 100 Hz 左右的频率和最大反作用力 Fcompr.= 3,450 N 的情况下。此外，在使用 5.76 × 106 个负载循环的疲劳测试中，可以检测到受损主轴轴承的温度从初始= 25 °C 到T最终> 80 °C 显着升高。因此，损坏的主轴轴承不适合永久运行。然而，在fmhp= 200 Hz附近的频率下，没有检测到假布氏磨损，并且疲劳试验期间温度没有明显升高。因此，这种未损坏的主轴轴承可以在不损害永久运行的情况下使用。
Machine hammer peening(MHP) is a high-frequency incremental forming process for surface treatment, which is used on milling machines. Because of the stationary motor spindle as a result of the pneumatic and electrical connections to the hammer head, point loads can occur and may initiatefalse brinelling wearon the spindle bearing rings. The aim of this work is an experimental and numerical analysis of the interdependencies between MHP reaction forces on the spindle adapter and bearings as well as the associated false brinelling wear of the spindle bearing rings during MHP. Firstly, MHP reaction force measurements on a servo-mechanical press with high stiffness with variation of frequency, electrical power, and time were conducted. Secondly, the spindle bearing wear during MHP was analyzed using fatigue tests and complementary simulations by means of numerical FE-software Abaqus 6.14 and softwareNewSpiladandWinLager. Thirdly, the effect of damaged spindle bearings on the milling operation was analyzed by means of an endurance test system for bearings. The results showed that false brinelling wear on spindle bearing rings occurs at frequencies aroundfmhp= 100 Hz and maximum reaction forces ofFcompr.= 3,450 N during MHP on milling machines. Furthermore, a significant raise in temperature of the damaged spindle bearing fromTinitial= 25 °CtoTfinal> 80 °Cduring fatigue test using 5.76 × 106load cycles could be detected. Thus, a damaged spindle bearing is not suitable for application in permanent operation. However, at frequencies aroundfmhp= 200 Hz, no false brinelling wear could be detected and the temperature did not raise significantly during fatigue test. Therefore, this undamaged spindle bearing can be used without impairment for permanent operation.
