METHOD AND APPARATUS FOR WITHDRAWING A MACHINE SHAFT |
摘要 |
The new method relates to a machinery assembly having (a) a housing, (b) an eccentric confined in the housing, (c) a shaft extending into the eccentric and (d) a shaft axis of rotation. A method for moving the shaft with respect to the housing includes the steps of applying a support force at a point on the housing so that such force places the housing substantially in equilibrium with respect to the axis. A withdrawing force is then applied to the shaft in a direction generally parallel to the axis. A jacking mechanism contacts the housing at a point to apply a support force to such housing. The force magnitude and direction place the housing substantially in equilibrium with respect to the axis to reduce or eliminate frictional forces. |
