Power take off for cordless nailer

摘要

A power tool that includes a structure; a flywheel coupled to the structure; a driver that is translatable along a driver axis; and a follower assembly having an actuator and an activation arm assembly. The actuator is coupled to the activation arm assembly. The activation arm assembly is coupled to the structure and includes a pinch roller. Actuation of the actuator causes the pinch roller to translate toward and engage the driver to initiate driving engagement between the driver and the flywheel.

1. A driving tool comprising:
a frame defining a rotational axis and a driver axis; a motor coupled to the frame; a flywheel that stores energy and is rotatably driven by the motor about the rotational axis and having an outer rim, the outer rim of the flywheel including an exterior surface that is configured with a plurality of circumferentially-extending teeth; a driver having a driver profile configured to be complementary to the outer rim of the flywheel, the profile having a complementary surface that is configured with a plurality of longitudinally extending teeth; and a follower arranged to push the driver profile into frictional engagement with the outer rim of the flywheel to transfer energy from the flywheel to the driver to propel the driver along the driver axis.
