Abstract
A nutrunner includes a housing, a motor with an output shaft rotatable about a first axis, a head including an output drive rotatable about a second axis, a transmission including a ring gear rotatable about the first axis, and a clutch mechanism. The clutch mechanism includes an adjustment collar rotatable about the first axis, rolling elements engaged with the ring gear, and a spring between the adjustment collar and the ring gear to bias the rolling elements into engagement with the ring gear. The clutch mechanism is configured to prevent the ring gear from rotating when a torque applied to the ring gear is less than a torque threshold, and to permit the ring gear to rotate when a torque applied to the ring gear is greater than or equal to the torque threshold. Rotation of the adjustment collar about the first axis adjusts the torque threshold.
