A very wide slider bearing lubricated with an oil having a viscosity of 0.075 N-s/m consists of two parts, each with a constant film thickness (see sketch b). Find the pressure distribution in the oil, the location of maximum pressure, and the load per unit width of the bearing at this film thickness. All dimensions are in millimeters. Ans. W/w = 2.068 MN/m. W/1082100 0.180 200 -100- 0.060 Un = 8 m/s Plot and compare the pressure distributions for the following slider bearings: (a) A parallel step slider bearing as described in Problem 1. (b) The same parallel step slider bearing, but with the step at x = 215 mm. (Note: This special bearing is called a Rayleigh step bearing) (c) A fixed-incline slider bearing with the same minimum film thickness, shoulder height and length as the bearing in Problem 1. (d) An exponential oil film shape given by h(x) = (ho+sh) e x/A and the same profile (shoulder height and minimum film thickness) as Problem 1. That is, h(x) = (0.060 +0.120) e */273, with all dimensions in mm. Estimate the load support per width from the area under the pressure curves. Comment on your observations. Hint: Books are great things. A very wide slider bearing lubricated with an oil having a viscosity of 0.075 N-s/m consists of two parts, each with a constant film thickness (see sketch b).
