The L.S. Starrett Co. has expanded its AVR Vision Metrology Line with the introduction of the AVR400 CNC Vision System, the largest benchtop platform to date from Starrett with stage travel that is twice the speed of previous Starrett AVR models. The stage travel is 15.8"x 11.8"x 7.9" (400 mm x 300 mm x 200 mm) in the X-Y-Z axes with a speed of up to 120 mm/sec.
This study aims to investigate the effect of this identified type of shot peening on the micropitting resistance of the gear tooth flanks and the macropitting resistance and to compare the experimental results with the calculation results based on standard methods.
An extremely wide selection of different plastic materials is currently available on the market. A major limitation, however, is a huge gap in gear-specific material data on these materials, which is a problem that has been persisting for decades now. Providing a step towards a solution is the German guideline VDI 2736, which proposes design rating methods (Ref. 2) along with testing procedures (Ref. 3) to be followed to generate reliable data required in the gear rating process. This paper delves into the current state of the art in plastic gear testing, providing a comprehensive overview of employed testing methods, supplemented with case studies.
This paper deals with the residual stress depth profiles in case-carburized gears, their effects on the fatigue behavior as well as the enhancement of ISO/TS 6336-4 to include the consideration of tensile residual stresses in the tooth core area. For this purpose, an equation is also presented with which these tensile residual stresses can be estimated so that they can be used in the enhanced evaluation of TFF risk.
This month's issue of Gear Technology covers a subject engineers love to learn about from others but hate to learn about through firsthand experience: gear failure. In a broad sense, all engineering is concerned with failure. Eventually, all parts fail, so engineers need to determine the limits of their design and ensure that it will meet the requirements of the particular application.
The Oregon Manufacturing Innovation Center Research and Development (OMIC R&D) recently welcomed Capture 3D, a Zeiss company, as a member of the collaboration, now at 41 members. Headquartered in Santa Ana, California, Capture 3D is a leader in innovative optical 3D metrology solutions, including accurate blue light 3D scanners, precision photogrammetry systems, comprehensive inspection software, and high-tech automated inspection systems.
