Bushing bearing stress
WebApr 4, 2024 · The conventional design process of journal bearings is completely based on deterministic theoretical predictions. The deterministic approach ignores the probabilistic and random nature of input variables and consequently, poses an arbitrary tolerance or safety factor on the performance parameters. In a bolted connection, the role of the bolts is normally to press one parts on the other; the adherence (friction) is opposed to the tangent forces and prevents the parts from sliding apart. In some cases however, the adherence is not sufficient. The bolts then play the role of stops: the screws endure shear stress whereas the hole endure bearing pressure.

The stresses developed when two elastic bodies are forced together are termed bearing stresses. They are localized on the surface of the material and may be very high due to the small areas in contact. The design information given in this section assumes either static loading or low velocity loading. The … See more Figure 11-1 shows a riveted connection between two plates. Excessive bearing stresses result in yielding of the plate, the rivet, or both. The intensity of the bearing stress between the rivet and the hole is not constant but … See more Given: The riveted plate in Figure 11-2 Find: The bearing stress between the rivets and the plate. Solution: The load per rivet is 20,000/4 = … See more Given: The cylinders shown in Figure 11-3. Find: The contact surface, total deflection, and maximum compressive stress. Solution: … See more Table 11-1 treats the elastic stress and deformations produced by pressure between bodies of various forms. The first column of this table gives the form of the bodies and the … See more WebThe simplest approximation for contact stress assumes the shaft makes contact to the bushing over half of its circumfer-ence and the contact pressure is constant over this …
