Abstract

The present invention relates to a driving apparatus for oscillation of a mold within a continuous casting machine and includes an eccentric shaft, having an eccentric shaft portion, rotatably mounted upon a frame, and an eccentric sleeve mounted upon the eccentric shaft portion. The eccentric sleeve is operatively connected to a mold oscillating system through means of a connecting rod, a first shaft connected to the eccentric shaft, a second shaft connected to the eccentric sleeve, and a clutch for rotating the eccentric shaft and the eccentric sleeve at different rates of revolution by means of a change-over transmission interposed between the two shafts so as to thereby change the oscillation amplitude of the connecting rod. According to the invention, the oscillation amplitude can thus be changed by remote control.

Dependent claims

A driving apparatus for oscillation of a mold within a continuous casting machine, which comprises:

an eccentric shaft, having an eccentric shaft portion, rotatably mounted upon a frame;
an eccentric sleeve mounted upon said eccentric shaft portion and operatively connected to a mold oscillating system through means of a connecting rod;
a first drive shaft operatively connected to said eccentric shaft;
a second drive shaft operatively connected to said eccentric sleeve;
drive means operatively connected to said first and second drive shafts for continuously driving said first and second drive shafts;
and
clutch means interposed between said first and second drive shafts for controlling the rotation of said first and second drive shafts and, in turn, the rotation of said eccentric shaft and said eccentric sleeve at the same rate of revolution when said clutch means is engaged so as to oscillate said connecting rod with a predetermined amplitude or at different rates of revolution when said clutch means is disengaged so as to thereby continuously alter the oscillation amplitude of said connecting rod.
