Abstract
A torque measurement tool measures the rolling torque of a bearing. The tool includes a bar weldment including a scale bar and a centered socket, and further includes a pair of slides slidably engaging the scale bar. Each slide has a thumb screw lock to fix a selected location and a rod adapted to engage the rotatable portion of the preloaded bearing (or engage a component attached thereto). A related method includes adjusting the slides to engage rods of the torque measurement tool with a rotatable bearing portion in a balanced condition, and using a torque wrench to obtain a reading of the torque required to move the rotatable bearing portion.
Claims13
A torque measurement tool for measuring rolling torque of a bearing, the bearing having rotatable and non-rotatable portions, comprising:
- a bar weldment including a scale bar and a centered socket adapted for connection to a torque wrench;
- and
- a pair of slides operably engaging the scale bar, each slide having a lock to fix a selected location on the bar and having an elongated member adapted to engage the rotatable portion of the bearing or a component attached thereto.
A method of measuring rolling torque of a bearing, the bearing having rotatable and non-rotatable portions, comprising:
- providing a bar weldment including a scale bar and a centered driver member adapted for connection to a torque wrench;
- providing a pair of slides operably engaging the scale bar and having an elongated member extending from each of the slides for engaging the rotatable portion of the bearing at equal distances from the centered driver member;
- engaging the elongated members with the rotatable portion of the bearing or a component rotatable with the rotatable portion of the bearing;
- rotating the scale bar and hence rotating the rotatable portion using a torque wrench engaged with the socket;
- and
- recording a measured value of torsional resistance from the torque wrench during the step of rotating.
A torque measurement tool comprising:
- a scale bar and a connector on the scale bar that is adapted for connection to a torque wrench;
- and
- a pair of spaced-apart elongated gripper members on the scale bar that are adapted to engage the rotatable portion of a bearing or a component attached thereto.
A method of measuring rolling torque of a bearing comprising:
- connecting a scale bar to a torque wrench;
- providing a pair of spaced-apart elongated gripper members on the scale bar;
- and
- engaging the elongated gripper members with a rotatable portion of one of a bearing or a component attached thereto while using the torque wrench to measure a rolling torque of the bearing.
