Abstract
The compressed air vibrator has a housing (1) with an inlet opening (8) for admitting compressed air to a chamber (14) and an outlet opening (9) for the exit of air from the chamber (14). Ball bearing assemblies (11, 15) are disposed with slight play on the shafts (2a, 2b) of the rotor (2). These ball bearings are fitted, also with slight play, in bores (12a, 13a) of oppositely located covers (12, 13) that close about the rotor (2) and close the open ends of chamber (14). The play is adjusted in such a way that the outer races (11a, 15a) of the ball bearings turn in the bores (12a, 13a) of the covers during the rotational movement of the rotor (2). The vibrator also can include a counter-flow air brake to slow rotor rotation.
Claims11
A compressed air, turbine drive, vibrator comprised of an outer housing having an internal cylindrical chamber terminating at two open ends, each open end being closed by a cover removably secured to said outer housing, said housing further including an inlet opening for admitting compressed air to internal chamber and an outlet opening for allowing the exit of air from the internal chamber, an unbalanced cylindrical rotor provided with a support shaft extending axially outwardly from opposite sides of the rotor, each support shaft being rotatably mounted within a ball bearing assembly, each said cover including an interior bore for receiving therein an outer race of one of said ball bearing assemblies in a manner that permits relative rotation between said outer race and said cover during rotation of the rotor.
