| This calculates the delfection of the pharmacie-dela-place outer race of a bearing when it is pressed into a housing. | ||||
| These equations are from Shigley and Mischke “Mechanical Engineering Design” Fifth Ediion p.62-63 | ||||
| Bearing | Housing | |||
| Modulus of Elasticity of Inner component (Ei) | 30000000 | Modulus of Elasticity of Outer component (Eo) | ||
| Inner Radius of Inner Component (land radius)(ri) | 0.1705 | Outer Radius of Outer Component (ro) | ||
| Poisson’s Ratio of Inner Component (vi) | 0.292 | Poission’s Ratio of Outer Component (vo) | ||
| Radius at Press (interface) (R) | 0.1875 | |||
| Radial Press (d) | 0.0003 | |||
