Abstract
An impact wrench comprises an anvil having impact jaws, a composite hammer including a driving part coupled to an output shaft of a pneumatic motor and a driven part having impact jaws for co-operating with the impact jaws of the anvil and mounted in the driving part for a combined rotation and a relative axial movement. A diametrical slot is provided in the driving part to receive a slider having its center of gravity offset relative to the hammer axis. The anvil receives a stub shaft mounted for a combined rotation together therewith and a relative axial movement and having a spring-loaded locking member co-operating with the slider. This construction of the pneumatic impact wrench enables a greater amount of kinetic energy to be transmitted into a threaded joint with each blow so as to improve the efficiency and reduce vibrations.
