Abstract

PURPOSE: To prevent the motor itself from resonance in such a way that the position in the center of gravity is lowered at the entirety of a vertical toothed wheel speed change gear composed of a motor and a vertical toothed wheel speed change gear to make the natural vibrating frequency higher in the vertical toothed wheel speed change gear.
CONSTITUTION: In concurrence of rigging a frame 11, etc. formed by I type steel to be fixed onto a motor stand 10 which is conical and supports a motor 1 with supporting the motor stand 10 on the upper side of this frame 11 by bolts, etc., a toothed wheel speed change gear 3 is attached to be housed in pit 7 by bolts, etc. Thereby, because the position in the center of gravity is extremely lowered at the entirety of a vertical toothed wheel speed change gear composed of a motor and a toothed wheel speed change gear, the natural vibrating frequency of the toothed wheel speed change gear grows higher in comparison with that of the motor itself, to avoid resonance condition.
