Abstract

PURPOSE:To prevent the rotation of a rocking scroll by a method wherein the rocking scroll and a stationary scroll are brought into engagement with each other through gears of the same number of teeth. CONSTITUTION:A stationary scroll 1 is formed by an end plate 1a and blades 1b while a rocking scroll 2 is formed by an end plate 2a and blades 2b and an eccentric pin 3a is connected to the bearing 2c of the rocking scroll 2 through a bearing 4. Further, a stationary side gear 5 fixed to the stationary scroll 1 and having (Z) number of teeth and a module (M) is brought into engagement with a rocking side gear 7 having the (Z) number of teeth and a module (M') at the side surface of the outer periphery of the end plate 2a of the rocking scroll 2. With the above structure, when a drive shaft 3 is rotated, the gear 7 is rotated as it inscribes the gear 5 and in this case, since both of the gears 5 and 7 have the same number of gear teeth and are different from each other only in their having different modules, the rocking scroll 2 does not rotate but rocks with respect to the stationary scroll 1. Consequently, it is possible to prevent the eccentric abrasion and the lowering of the capacities of the scrolls 1 and 2.
