Abstract
The present patent application for a machined and damped crown wheel and pinion for an electropneumatic hammer, consists in the production of an electropneumatic hammer for use in the building sector that uses an improved crown wheel and pinion that incorporates in the rotor a flexible coupling device in order to reduce the actual loads on the components of the hammer. This type of solution or invention results in a number of improvements that are listed below: simplicity of mounting and in particular simplicity of construction reduced loads and vibration of the parts - reduced costs of production - improved hammer life and performance - simplified and less expensive repairs - overall wear reduced owing to the characteristics described above. <IMAGE>
