US 2017/0291269 A1 · DRIVE SHAFT PRESS

Abstract

A simplified drive press system is operable to press fit a pair of first working pieces into a second work piece. The drive press system uses a simplified mechanical arrangement to translate an input torque into movement of a pair of drive arms toward and away from one another. Yokes of differing configurations may be attached to the drive arms to accommodate a variety of different work pieces. A nut runner may be used to supply a drive torque to the gear assembly and provide a controlled input torque and control the movement of the drive arms. An overall reduction may be utilized that balances a desired movement resolution with the desire to detect changes in input torque. The nut runner may be programmable to provide a desired movement of the drive arms while monitoring the input torque to detect when a fully press-fitted condition is realized.

Dependent claims

A press system comprising:

at least one moveable rack, the at least one rack being operatively connectable with a first work piece and operable to move the first work piece relative to a second work piece, the at least one rack having a plurality of gear teeth;
a mechanical drive system operable to move the at least one rack and a connected first work piece relative to the second work piece, the drive system including a gear assembly operatively coupled to the at least one rack and an input member operatively coupled to the gear assembly, rotation of the input member driving rotation of the gear assembly;
and
a nut runner operatively connectable to the input member, the nut runner operable to supply a drive torque to the input member to drive movement of the at least one rack and press fit the first and second work pieces together.
