Outline

Autocom Manufacturing, a division of Linamar, is a Guelph ON based manufacturer of auto transmission parts. A torsion rig was designed for testing torque on an automotive transmission component up to 3,500 foot lbs. In order to achieve precise measurement, they considered both hydraulic and mechanical solutions to move the torsion arm, however hydraulic cylinders were eliminated as the company did not want any backlash to occur during testing. They approached Trans-Quip Inc. for a mechanical solution.

Along with engineering assistance from jack manufacturer Joyce/Dayton, Trans-Quip was able to supply Autocom with a mechanical screw jack and handwheel (Model #WJT125U1K-6-HW12-STDX-B). This system allows the operator to manually turn the handwheel, raising the jack that actuates the torsion arm until the required torsion level was exerted onto the part.
