Photoelastic investigation into stresses in high transverse contact ratio gears

Transactions of FAMENA, 2009
A photoelastic investigation into the tooth root and Hertzian stresses in involute external spur high transverse contact ratio (HCR) gears was carried out on a photoelastic model with two gear segments in mesh. A double or triple contact of tooth pairs was obtained by shifting and rotating the segments. The intention was to simulate the real total load

An Analysis of Time-Varying Meshing Stiffness of High Contact Ratio Gears Considering a High-Order Modification Curve

In this investigation into the technology of tooth profile modification, we analysed the impact of meshing, meshing shocks, and load distribution of high contact ratio gears in detail and explained the necessity of tooth profile modification so that a ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Transmission of multidrug-resistant tuberculosis in the UK: a cross-sectional molecular and epidemiological study of clustering and contact tracing

, 2014
BACKGROUND: Between 2000 and 2012 the number of multidrug-resistant (MDR) tuberculosis cases in the UK increased from 28 per year to 81 per year. We investigated the proportion of MDR tuberculosis cases arising from transmission in the UK and associated ...

Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

Advanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

Advanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Influence of linear profile modification and loading conditions on the dynamic tooth load and stress of high contact ratio gears

, 1990
A computer simulation for the dynamic response of high-contact-ratio spur gear transmissions is presented. High contact ratio gears have the potential to produce lower dynamic tooth loads and minimum root stress but they can be sensitive to tooth profile
