摘要： In a scroll compressor, a center of a turning scroll body is shifted with respect to a drive central axis so that a distance between a gravity center and the drive central axis in a turning scroll becomes smaller than a predetermined allowable value set based on theoretical displacement and mass of the turning scroll. A moment force about the drive central axis acting on the turning scroll is reduced during revolving, and an alternating force acting on an autorotation preventing pin in the turning scroll is reduced to an allowable level.

摘要： A scroll compressor includes a fixed scroll and an orbiting scroll, each including a spiral wrap protruding from an end plate and having the same tooth thickness (Tr) and the same base-circle radius (b) defining an involute surface. The fixed scroll and the orbiting scroll are offset from each other by an orbiting radius (ρ) and mesh such that the respective wraps face each other with a phase shift of 180°. The orbiting scroll revolves/orbits along a circular orbit with the orbiting radius (ρ) to compress a gas while a rotation-preventing mechanism prevents rotation of the orbiting scroll. The relationship between the involute surfaces of the spiral wraps of the two scrolls and the dimensions, dimensional tolerance, and assembly standards of the rotation-preventing mechanism are determined so that the median value of an allowable angle of rotation (φ) agrees with an upright position of the orbiting scroll.
