Bearings load-carrying capacity

Three-lohe heating. The three-lobe bearing is not commonly used in turbomachines. It has a moderate load-carrying capacity and can be operated in both directions. 

Offset halve.s. In principle, this bearing acts very similar to a pressure dam bearing. Its load-carrying capacity is good. It is restricted to one direction of rotation. 

Load-carrying capacity and life expectancy of bearings 8/214... 

In plain bearings, the lubricating fluid must be replenished to compensate for end leakage in order to maintain their load-carrying capacity. Pressure lubrication from a pump-or gravity-fed tank, or automatic lubricating devices such... 

Figure 60.27 shows the ball installation procedure for roller bearings. The designed load carrying capacity of Conrad-type bearings is determined by the number of balls that can be installed between the rings. Ball installation is accomplished by the following procedure ... 

The integration of the gas pressure gives the load carrying capacity, F, of a bearing,... 

Let us compare the magnitude of the van der Waals pressure with that of air bearing pressure. In Section 3.2, we have shown the numerical solution of gas pressure distribution for a two-rail slider and a O t pe slider. By simply summing up the contributions of gas pressure and van der Waals pressure and integrating over the whole slider surface area, the total dimensionless load carrying capacity becomes... 

Groszek and Witheridge showed that such oleophilic powders are highly effective in increasing load-carrying capacity. They provided some evidence that the effectiveness is due to the fact that oleophilic particles preferentially attach to bearing surfaces in a basal plane orientation. In that orientation the molybdenum disulphide would provide less opportunity for capillary penetration, and would be less susceptible to chemical reactions. 

From Eqn 2-40 by various treatments one can obtain information of engineering value, such as the distribution of pressure around the bearing, the response of journal attitude to load, the load-carrying capacity of the bearing, etc. Details of how such problems are handled can be found in texts specially devoted to the analysis and operation of bearings.
