Abstract

1301855 Vibrators LITHGOWS Ltd 14 May 1970 [15 May 1969] 24745/69 Heading F2X In a vibrator, a number of separate masses are rotated about a common axis by a prime mover, the relative angular positions of the masses being adjustable during rotation, to effect both static and dynamic balancing. The masses 1 to 14 are mounted on the same shaft are driven from I.C. engine 15 through the shafts a, b, c, d, e and f, chain sprockets and differential geat boxes A, B, C, D and E. The relative angular positions of the masses are altered by rotation of the ring gears, e.g. 18, on the gear boxes. The ring gears are linked together such that they rotate at a constant ratio to each other. Initially, the vibrator is run up to speed in a balanced condition and then the masses are displaced angularly.
