A comparative study on the performance of differently treated plain carbon steel gears
TL;DR: In this paper, a back-to-back gear test rig was used to evaluate the wear characteristics of low carbon steel (C14) gears in the untreated condition as well as those heat treated by different methods (carburized, Sursulf treated, Tufftride treated and duplex treated in two different ways) in a back to back gear test setup.

TL;DR: In this article, a study on the wear and friction of hardened AISI 1045 steel using a tri-pin-on-disc type of friction and wear apparatus was made.
Abstract: A study has been made on the wear and friction of hardened AISI 1045 steel using a tri-pin-on-disc type of friction and wear apparatus. During the investigation the linear pin wear, coefficient of friction and rise in pin specimen temperature were monitored and wear and friction curves plotted. Wear surfaces and mechanisms were investigated by means of optical microscopy. Analysis of used lubricating oil was performed using FTIR spectroscopy. It was shown that the wear rate, type of wear and friction coefficient were influenced by contaminating the lubricant with bio-fuel as well as the surface hardening treatment. Corrosive wear and pits on the specimen surface were found when plain bio-fuel was used as lubricating oil. The results also confirmed that better wear resistance was obtained from the surface-hardened steel specimen with 4 % bio-fuel-contaminated lubricant. Results from this study will be useful in material selection for tribological components in diesel engines running on vegetable fuel. Pres...

01 Jun 1974TL;DR: Pitting tests using 127 mm (5 in) centres distance gear rig under controlled conditions are described in this paper, which confirm Dawson's conclusion that an important factor influencing pitting life is the ratio of surface roughness to the calculated lubricant film thickness.
Abstract: Pitting tests using 127 mm (5 in) centres distance gear rig under controlled conditions are described. These are compared with similar disc tests using the same materials and lubricants. Tests of both types confirm Dawson's conclusion that an important factor influencing pitting life is the ratio of surface roughness to the calculated lubricant film thickness. It has been shown that using a hunting tooth ratio, particularly when associated with a rough harder surface and a surface finish oriented normal to the motion, increases the likelihood of wear. Most importantly, the results show that using disc tests can greatly overestimate the pitting life of gears. These experiments and other evidence from the literature suggest that the most probable reason for these differences between gears and discs lies in dynamic gear loads.
