ABSTRACT:
The housing of a rotary ball type industrial vibrator is injection molded from a reinforced plastic material, and an annular metal raceway structure is molded integrally with the housing and forms a contact surface for a metal ball disposed within the interior of the housing. In response to a flow of pressurized air through the housing, the ball is rapidly rotated around the metal raceway to impart oscillating vibrational forces which are transmitted through the housing to a bulk material handling structure to which it is rigidly secured. The light weight plastic housing facilitates a highly efficient vibrational force transfer to the material handling structure, and the integrally molded metal raceway structure isolates the rotating ball from the interior plastic housing surface to prevent internal housing abrasion, and significantly reduces operational noise generation. In one embodiment of the vibrator, a single tangentially directed stream of pressurized fluid is utilized to drive the ball around the raceway structure, while in another embodiment a circumferentially spaced plurality of pressurized fluid streams are simultaneously utilized.
