ABSTRACT:
An oscillator for a continuous casting mold includes a rotatable drive shaft having first and second portions which are eccentric with respect to one another. A sleeve for inducing oscillatory motion of the mold rotatably surrounds the second shaft portion and is eccentric with reference to the latter as well as the first shaft portion. The sleeve is coupled to the housing of a gear reducer having a gear assembly which is rotatable relative to the housing and is coupled to the drive shaft for rotation therewith. The housing is, in turn, connected with the casing of a motor having an output shaft which is rotatable relative to the casing and is coupled to the gear assembly. This motor constitutes an auxiliary motor which is operable independently of a primary motor for the drive shaft. During normal operation, the auxiliary motor is deactivated and the sleeve, gear reducer and auxiliary motor all rotate with the drive shaft as this induces reciprocation of the mold through the agency of the sleeve. If the magnitude of the oscillation stroke is to be changed, the auxiliary motor is activated. This causes the sleeve to rotate relative to the drive shaft so that the eccentricity of the sleeve with respect to the first portion of the drive shaft, which determines the magnitude of the oscillation stroke, changes. The auxiliary motor and the gear reducer are at least approximately coaxial with the first portion of the drive shaft thereby enabling the auxiliary motor to be small and the oscillator to be compact.
