Abstract

The invention discloses a rotary pulsed friction generator and a wheel shaft eccentric angle sensor, wherein the generator is arranged on a rotating device. The generator comprises the components of a first power generating friction layer (102); a power generating layer which is arranged on a rotating wheel of the rotating device and is used for contacting with or separating from the first power generating friction layer (102) and generating electric charges on the contact surface of the power generating layer; a first contact sheet set which is electrically connected with the power generating layer; and a second contact sheet set which is grounded or connected with an equipotential source and is used for contacting with the first contact sheet set once in each process of the processes in contacting with and separating from the first power generating friction layer by the power generating layer, and furthermore the second contact sheet set forms a closed circuit in contacting, thereby forming instantaneous positive pulse current or instantaneous negative pulse current. The rotary pulsed friction generator can convert rotary mechanical energy to electric energy by means of self structure of the rotating device and furthermore has a simple structure.
