Abstract
PURPOSE:To reduce the moment of inertia of a driving system and obtain a complete balance by supporting a balance weight so as to be capable of relative rotation on a different eccentric shaft connected between a rotary shaft and an eccentric shaft supporting a movable scroll member. CONSTITUTION:The first eccentric shaft 8 with a central axis 01 off-centered by a certain distance R1 from a central axis 0 of a rotary shaft 5 is fitted inside the rotary shaft 5, and the second eccentric shaft 11 with a central axis 02 off- centered by a certain distance R2 from the central axis 0 of the rotary shaft 5 in the exactly opposite direction to said central axis 01 is fitted to the tip of the eccentric shaft 8. Thus, a different eccentric shaft 8 is connected between the rotary shaft 5 and the revolving eccentric shaft 11 of a movable scroll member 13, and a balance weight 10 is supported to the eccentric shaft 8 so as to be capable of relative rotation. Therefore, a complete balance can be obtained, the moment of inertia of the driving system is reduced, the resistance during acceleration and deceleration is reduced, and power losses and oscillations, etc. can be decreased.
