Experiments of scoring and the calculation of scoring on gears by heat method

Analysis of Scoring Resistance on Coated Spur Gears by Considering Surface Roughness

“…In the experiments, gears were rotated with a speed of 3000 rpm and the oil temperature constant at 323±2 °K as appropriate to the literature [3,4,7]. Gears were exposed to loading at 15.2 Nm and continued by increasing 20 % until scoring formation was observed.…”

“…Between every stage of the experiment, surface roughness and weight measurements were repeated. When values of weight showed a sudden increase, the scoring formation was examined by controlling the surface of the tooth [2,3]. In case there was not a sudden change in weighing, adding weight was continued.…”

“…The changing of weight in the pinion to determine the critical scoring load Areas that roughness measured ratio. Hence, wear is observed earlier in the pinion gear[1][2][3].…”

“…In theoretical studies some methods have been presented by Authors for the calculating of scoring. These methods are based on pressure or surface temperature on tooth profile when the gears are in action [3][4][5][6][7][8][9][10][11][12][13][14]. In experimental works, the closed circuit power circulating gear wear test mechanism (FZG) is used to investigate the strength of gears as a result of rapid wear [2,[15][16][17][18][19][20][21][22][23][24].…”

Investigation of influence of load and velocity on scoring of addendum modified gear tooth profiles

“…Some researchers have worked on limiting load for scoring and temperature rise and friction loss by using different lubricants on modified spur gear pairs [3,4] and [5]. In some studies calculations on scoring have been made [6,7].…”
