Scroll type fluid machinery and assembling method of the same.

摘要

The present invention relates to a scroll type fluid machinery in which a stationary scroll (10) and a revolving scroll having spiral wraps set up on inner surfaces of end plates, respectively, are engaged with each other at a predetermined angle dislocation and housed in a housing with one end opening of a cup-shaped casing (2) blocked with a front case, the stationary scroll (10) is fixed to the cup-shaped casing (2), and the revolving scroll is made to revolve in a solar motion by means of a revolution drive mechanism while checking the rotation on its axis by means of a mechanism for checking rotation on its axis, and an assembling method thereof, in which positioning portions (52,53) which are engaged with a positioning jig (51) are provided in the stationary scroll (10) and the cup-shaped casing (2), respectively, and the positioning portions are utilized. With this, number of parts, working mandays and assembly mandays are reduced and the manufacturing cost may be cut down. <IMAGE>
