This article describes a methodology to investigate micro-pitting damage on bearing steels using a twin-disc machine to better represent mechanical components, i.e. bearings, crankshafts, etc. In addition, effects of roughness, hardness and the ZDDP additive are presented and discussed. A ...
Workpiece material-100Cr6 (AISI52100) bearing steel, PVD-TiNAlN-coated cutting insert (vc=250 m/min, f=0.12 mm/rev, ap=1 mm) [24]. The integral effect of both SEM microphotograph and X-ray map in differentiating between the sticking and sliding regions across the tool–chip interface is...
Pitting the teamed VRM against a phase-doubled solution results in near identical thermal performance. Thermal performance Each VRM component serves a specific purpose. PWM controllers and phase-doublers control the circuit, and the power stages do the heavy lifting from an electrical and...
aThe pitting spots that appear in some micro-areas of the films extend into the interface between MoS2 film and bearing substrate, even into the substrate. 在影片的一些微区域出现的点蚀斑点延伸到MoS2影片和轴承基体之间的接口,甚而入基体。[translate]...
Excessive crankshaft bending due to a main bearing failure, which increases the crankshaft bending stresses. How a detuner or torsional vibration damper can reduce the effects of torsional vibration ? The fitting of either a detuner or vibration damper will reduce the vibration levels of the cranks...
