A8GT-70GOT-EB日本发那科 G2CrNi2Mo渗碳钢制圆锥滚子轴承外圈，在使用过程中出现开裂现象。由于该轴承产量高，使用部位关键，为避免再出现同样的开裂现象，必须找出其产生失效的原因。本文通过宏观分析、微观分析、扫描电镜的分析，就开裂的原因进行了讨论。渗碳钢制圆锥滚子轴承外圈开裂失效分析1.外圈开裂宏观特征失效的渗碳钢制圆锥滚子轴承外圈外表面除有一条贯通的、且与轴线平行的开裂裂纹外，还有两条源自大裂缝的散射细裂纹。除两端及中部非工作区外，套圈上有两道大的磨损区，呈不同的亮白色光泽带。 MVME172-233 MVME172-233A MVME172-243 MVME172-243A MVME172-253 MVME172-253A MVME172-263 MVME172-263A MVME172-303 MVME172-303A MVME172-313 MVME172-313A MVME172-323 MVME172-323A MVME172-333 MVME172-333A MVME172-343 MVME172-343A MVME172-353 MVME172-353A MVME172-363 MVME172-363A MVME172-373 MVME172-373A MVME172-410 MVME172-410A 51400978-100 Processor (early version) 51400988-100 US Touchscreen, Smart 51400988-200 US Touchscreen, Smart, CE 51400997-100 PLC Gateway Interface博大精深 同心致远 51400997-200 Enhanced PLC Gateway I/F 51401052-100 SPC Card 51401072-200 QMEM-2 51401072-300 3 M-Word Enhanced Memory博大精深 同心致远 51401088-100 CNI - Interface for PLNM 51401163-100 Process Network Modem-NIM 51401286-100 EPDG Interface Card 51401286-100 EPDG Interface Card博大精深 同心致远 51401288-100 68020 w/2 Meg 51401288-200 68020 w/3 Meg 51401291-100 LCN I/F 51401291-100 Low Power LCN (LLCN) 博大精深 同心致远 51401496-100 Dual Node Fan Assembly 51401497-100 Dual Node Power Supply 51401551-200 68020 w/2 Meg 51401551-300 68020 w/3 Meg博大精深 同心致远 51401551-400 68020 w/4 Meg 51401551-600 68020 w/6 Meg 51401551-800 68020 w/8 Meg 51401560-100 QWERTY Membrane Keyboard博大精深 同心致远 ABB微型断路器S203-D63 ABB微型断路器S204-D0.5 ABB微型断路器S204-D1 ABB微型断路器S204-D2 ABB微型断路器S204-D3 ABB微型断路器S204-D4 ABB微型断路器S204-D6 ABB微型断路器S204-D10 ABB微型断路器S204-D16 ABB微型断路器S204-D20 ABB微型断路器S204-D25 ABB微型断路器S204-D32 ABB微型断路器S204-D40 ABB微型断路器S204-D50 ABB微型断路器S204-D63 ABB微型断路器S201-D0.5 ABB微型断路器S201-D1 ABB微型断路器S201-D2 ABB微型断路器S201-D3 ABB微型断路器S201-D4 ABB微型断路器S201-D6 ABB微型断路器S201-D10 ABB微型断路器S201-D16 ABB微型断路器S201-D20 ABB微型断路器S201-D25 ABB微型断路器S201-D32 ABB微型断路器S201-D40 ABB微型断路器S201-D50 ABB微型断路器S201-D63 ABB微型断路器S202-D0.5 ABB微型断路器S202-D1 ALLEN BRADLEY 291E-FAZ-G1-3FR / 291EFAZG13FR (NEW NO BOX) ALLEN BRADLEY 872C-A10C18-A2 / 872CA10C18A2 (USED TESTED CLEANED) ALLEN BRADLEY 961454 / 961454 (USED TESTED CLEANED) ALLEN BRADLEY 871TM-BH2N12-B4 / 871TMBH2N12B4 (USED TESTED CLEANED) ALLEN BRADLEY 32A24 / 32A24 (USED TESTED CLEANED) ALLEN BRADLEY 855T-B10YL3 / 855TB10YL3 (USED TESTED CLEANED) ALLEN BRADLEY 193206-A01 / 193206A01 (USED TESTED CLEANED) ALLEN BRADLEY 50906 / 50906 (USED TESTED CLEANED) ALLEN BRADLEY CF-271 / CF271 (NEW NO BOX) ALLEN BRADLEY 1610L-T0220SA1 / 1610LT0220SA1 (NEW NO BOX) ALLEN BRADLEY 140-L2 / 140L2 (NEW NO BOX) ALLEN BRADLEY GA-473 / GA473 (Used) ALLEN BRADLEY 190-P024R / 190P024R (RQANS1) ALLEN BRADLEY 1777-IB / 1777IB (USED TESTED CLEANED) ALLEN BRADLEY 871TM-DH2NN12-D4 / 871TMDH2NN12D4 (RQANS1) ALLEN BRADLEY 100S-D110A22C / 100SD110A22C (NEW NO BOX) ALLEN BRADLEY 1799-D10U10BL / 1799D10U10BL (USED TESTED CLEANED) ALLEN BRADLEY 801-ASC27 / 801ASC27 (USED TESTED CLEANED) ALLEN BRADLEY 60-2668 / 602668 (USED TESTED CLEANED) ALLEN BRADLEY 1771-CX5 / 1771CX5 (NEW IN BOX) ALLEN BRADLEY 205-BOG / 205BOG (USED TESTED CLEANED) ALLEN BRADLEY 91886 / 91886 (USED TESTED CLEANED) ALLEN BRADLEY 1798-BP4 / 1798BP4 (USED TESTED CLEANED) ALLEN BRADLEY 440E-E25010 / 440EE25010 (USED TESTED CLEANED) ALLEN BRADLEY 197-FLA2 / 197FLA2 (RQANS1) ALLEN BRADLEY 855T-BSPM60 / 855TBSPM60 (USED TESTED CLEANED) ALLEN BRADLEY 855BS-N24DH5 / 855BSN24DH5 (USED TESTED CLEANED) ALLEN BRADLEY 285-BRC25-M6 / 285BRC25M6 (RQANS1) ALLEN BRADLEY CWEB4-VS2 / CWEB4VS2 (RQANS1) ALLEN BRADLEY 440E-D13124 / 440ED13124 (USED TESTED CLEANED) ALLEN BRADLEY 42JT-B2LAT2-P4 / 42JTB2LAT2P4 (USED TESTED CLEANED) ALLEN BRADLEY 500F-COD-93 / 500FCOD93 (USED TESTED CLEANED) ALLEN BRADLEY 610936-01 / 61093601 (USED TESTED CLEANED) ALLEN BRADLEY 802T-W4A / 802TW4A (Surplus New In Box)  一般使用车床进行机械加工时，会发生所谓的振刀的场合大概有这几种场合：利用成型刀片进行成形车削；细长圆杆的外圆车削；薄肉圆杆的外圆车削；箱形部品（如钣金焊接结构件）车削；超硬材质切削；轴承已受损而继续切削等。当振刀发生时，刀具、工件与车床的振动往往导致工厂内部有刺耳的噪音，而其振幅大小单边达数十微米以上，有时其至高达1微米以上。这种振刀不仅造成刀具或工件的夹持变松之外，同时也因其嘈杂的噪音对操作人员造成不良的身心影响，而加工精度也因此无法达成客户的要求，因此各工具机厂莫不战战兢兢地将振刀问题之排除视为莫大的挑战。 |
