WebApr 2, 2024 · The gripping force of these chucks is powerful enough to actually compress the tool shank slightly and expand into the slits. Tests show that the chucking torque force can deliver up to 5000Nm or 3700lbf and this combined with an acceptable radial runout of less than 0.00019in. ... On the other side the shrink fit can only use flush or through ... WebThe calculator is based on elastic deformation (Lame's equation), i.e. the stresses should be smaller than the elastic limit Rp0.2 of the elements. The interference should be corrected for the effect of surface roughness. The …
WebApr 3, 2024 · For the shrink-fit camshaft in our case, the range of friction coefficient is 0.14–0.19. After that, the relationship between the torque capacity and the radial interference for the shrink-fit camshaft is established by the finite element model for torque capacity testing based on the friction coefficient obtained before. WebNov 12, 2024 · Fits are either shaft or hole-based. A hole is a component’s internal feature that is cylindrical or not, while a shaft is a component’s external feature that is cylindrical or not. The hole’s size is kept constant for a hole-basis system while the shaft is altered to determine the fit.

WebApr 14, 2011 · If you start with a 0.010 heavy shrink fit (overlap) you will end up with a 0.010 (+/- .002 or so) overlap at final temperature. That 0.030 overlap (a compression force on the shaft) adds a tremendous pre-loaded tension stress on the outer part even before centrifugal forces and dynamic loads are begun.
