Consider a flat collar (also known as thrust collar) bearing supporting a shaft as shown in Fig.6.20.
FLAT COLLAR BEARING (OR THRUST BEARING) Consider a flat collar (also known as thrust collar) bearing supporting a shaft as shown in Fig.6.20. Let W = Total axial load transmitted to the bearing surface, r1 and r2 = External and internal radius of the collar respectively, p =Intensity of pressure, and μ = Coefficient of friction between shaft and bearing surface. When the pressure is assumed to be uniform over the bearing surface, then the intensity of pressure is given by The total torque required to overcome the friction for the uniform pressure condition is given by Total torque required to overcome the friction for the uniform wear condition is given by Power lost in overcoming the friction is given by P = T • ω
