Abstract
A gas spring-powered fastener driver includes a cylinder, a moveable piston, a driver blade attached to the piston, the driver blade movable with the piston, a lifter including a rotary component operably coupled to the driver blade to move the driver blade from a driven position to a ready position, and a multi-stage planetary transmission. The transmission includes an output shaft operatively coupled to the lifter to provide torque thereto, a first bearing supporting a first portion of the output shaft for rotation, a second bearing supporting a second portion of the output shaft for rotation. The fastener driver also includes a housing having a cylinder support portion in which the cylinder is received and a transmission housing portion in which the first and second bearings are received to rotatably support the output shaft. The cylinder support portion and the transmission housing portion are integrally formed as a single piece.
