Title:
スクロール式流体機械及びその組立方法
Document Type and Number:
Japanese Patent JP6734378
Kind Code:
B2
Abstract:
The objective of the present invention is to provide a scroll-type fluid machine, and a method for assembling this scroll-type fluid machine, with which an eccentric shaft and a non-eccentric part can be positioned easily in the same step, while allowing a main body unit and a motor unit to be separated and connected without being disassembled. To achieve this objective, this scroll-type fluid machine is equipped with a main body unit having a main body casing, a fixed scroll, and an orbiting scroll, and a motor unit having a drive shaft for driving the main body unit, and a motor casing, wherein the drive shaft protrudes from the motor casing and is attached to a slewing bearing of the main body unit, positioning holes into which a positioning member is inserted are formed on their respective opposing mating surfaces of the motor casing and the main body casing, and the dimensional difference between main-body-casing-side insertion opening of the positioning hole and the motor-casing-side end surface of the slewing bearing in the axial direction is less than the dimensional difference between the main-body-unit-side tip ends of the drive shaft and the positioning member in the axial direction.
