WebFeb 17, 2024 · Consequently, the interference fit is also known as a friction fit. The tightness of interference fits comes from its negative clearance. This means that the mating surfaces press into each other. In other words, the mating surfaces deform inwards under contact pressure. WebThe results look ok, the difference in contact pressure is actually less than 1% in corners.

WebThe interfaces of thick-walled cylinders are subjected to contact pressure P C under the action of the interference fit. Tangential stress σ φ on the inner surface of the cylinder’s outer layer is produced by contact pressure P C , which causes the crack of length a to amplify gradually and form a singular stress field at the crack tip [ 32 ]. WebMar 8, 2016 · The contact pressure size should be selected such that the fretting fatigue is avoided and on the other hand as high as possible to fully take advantage of the interference fit. A constant contact pressure between the parts can be achieved in different ways; one possibility is to make changes to the contacting surfaces, however as … WebSep 21, 2024 · Multilayer interference fits are widely used in the machinery industry, and their performance is closely related to assembly quality.

These types of fits always have the same principle of having a larger shaft compared to the hole size. Max interference – left; min interference – right The assembly stage requires force, sometimes lubrication, heating of the hole and freezing of the shaft.

WebMar 27, 2024 · The forces associated with a press, or interference, fit are determined using equations and pre-established values. These equations assume that the shaft is treated as a cylinder with a uniform external pressure, and the hub is treated as a hollow cylinder with uniform internal pressure. WebMar 29, 2024 · The contact pressure of a multi-layer interference cylinder decreases linearly with the increase of temperature gradient. The analytical solution is basically consistent with the numerical solution, and the maximum relative error of midpoint is 11.62% and −7.69% under two factors.
