Atra-Flex: Installation & Maintenance Guide

Installation of Jackshafts

1. Follow all steps preceding with the floater hub and floater rings installed on the output driver and the driven side of the application. 2. Make sure you have allowed for the “E” dimension when the center shaft is lifted into place. 3. Lift and support the center section shaft at both ends. Position it in alignment with driver and driven shaft hubs. 4. Install inserts. 5. Check “E” dimensions at both ends. 6. Move the floater rings into position and bolt them to the floater hubs. For snap-ring designs, install the snap rings. 7. Remove center section supports slowly. 8. Replace all guarding.

Installation of End-Float Limiting Couplings

1. Locate the magnetic center of the motor and mark the shaft. 2. Mount coupling hubs onto the shafts so that the “E” dimension will be correct when the motor is in its magnetic center or center of its total axial travel when mounted in place. Place ring over one hub on either side of application. 3. Align coupling per Installation Section #3. 4. Check “E” dimension. 5. Install the insert into coupling. 6. Install ring over insert. 7. Check that motor shaft is in its center of axial travel (mark on shaft). 8. Replace all guarding before start-up.

Installation of Horizontal Shear / Slide Couplings

1. Adjust the DBSE according to the minimum or maximum the coupling is designed for. 2. Set shafts in the position of travel in or out or combination of both. 3. Mark shaft for non-flange hub position. 4. Install non-flanged hub onto shaft. 5. Install flanged hub onto shaft flush with end of shaft. 6. Install ring, insert and winged plate into non-flanged hub. For spacer-type couplings, assemble the spacer unit with ring, insert

and both winged plates, then bolt to the flange hubs (one on each end of shafts). 7. Place flanged hub equipment in position and bolt flange hub to winged plate. 8. Align coupling per Installation Section #3. 9. Check “E” dimension and overall travel of coupling. 10. Replace all guarding before start-up.

Note: Interference fit hubs should be heated in an oil bath or oven to a maximum of 275 degrees fahrenheit. The flashpoint of the oil must be 350 degrees fahrenheit or higher.
