Abstract

PURPOSE: To reduce noise by decreasing an unbalance mass caused by a pin eccentric part on a side remote from a motor, which constitutes a balance system for a shaft and by a roller so as to make the unbalance mass smaller than a similar mass on the motor side, in order to reduce a deflection of the shaft.
CONSTITUTION: In a casing 2, two cylinders 5a, 5b are held between main and auxiliary bearings 3, 4 with a partition plate 10 intervening therebetween, and a shaft 2 is borne by the main and auxiliary bearings 3, 4. Rollers 6a, 6b are fitted on the outer diameter parts of pin eccentric parts 2a, 2b of the shaft 2, and vanes partitioning the insides of the cylinders 5a, 5b are arranged at the outer peripheral surfaces thereof. In this arrangement, a recess 6c is formed in the inner surface of, for example, the roller 6b in order to make an unbalance mass caused by the pin eccentric part 2b and the roller 6b on the side remote from a motor, smaller than that caused the pin eccentric part 2a of the shaft 2 and the roller 6a in the cylinder 5a on the motor side.
