Therefore the diameter of pinion Dp 5 m 3 number of teeth in pinion 5 4 3 14 5 56 mm. Hence the radius of pinion rp 5 28 mm. Similarly radius of gear rg 5 4 3 49/2 5 98 mm. 33 m/s. 4 N. 9 N. This normal load acts along the pressure line, which is fixed if the teeth are of involute shape and gears have no vibration disturbing the position of centers of gears. 3 shows the pressure line, pitch circle, base circle, and addendum circle of pinion and gear. The tooth engagement starts at A1 and ends at B1 .
This assumption is valid in lubricated contact in which oil bath temperature may be taken as bulk temperature [9]. The main reason for 58 Modeling of Chemical Wear this is the convective cooling due to the oil that tends to equalize the temperatures. The dry contact situation is more complex and the bulk temperatures can be different for both surfaces, and the problem needs a complete heat transfer analysis using proper boundary conditions [10,11]. The other complications that arise include variations in thermal properties due to temperature as well as influence of oxide and other films on heat transfer [12].
