| Abstract | ||||
| A formula for the oil film thickness in elasto-hydrodynamic lubrication for the gears of circular-arc tooth-profile is derived in terms of all parameters. This required the simultaneous solutions of the Reynolds equation with the elasticity equation by using the finite difference method. This formula represents a simple tool for the designers, where the oil film thickness can be calculated, and the corresponding load capacity of the gears of circular arc tooth-profile are determined, for any given speed, helix angle, radii of curvature, lubrication properties and material of the gears, The calculated oil film thickness obtained from the presented formula is compared with the existing theories of elastohydrodynamic lubrication equations developed by Hamrock and Dowson, Cheng and Archard and Cowking and shows that the calculated values of the oil film thickness obtained from the presented formula are greater. | ||||
