Abstract: Methods, systems and apparatuses for mounting a motor rotor to a shaft of a compressor are disclosed. The shaft can include a rib region that is configured to form a press fit or a transition fit with the rotor bore. An end of the shaft can also include a plurality of crenulations that can be expanded outwardly in a radial direction relative to a centerline of the shaft. After the rotor is mounted onto the shaft, the crenulations can be expanded to eliminate the clearance between the shaft and the rotor to form a press fit with the rotor bore.
Abstract translation: 公开了一种用于将马达转子安装到压缩机的轴上的方法，系统和装置。 轴可以包括肋区域，其被构造成形成压配合或与转子孔的过渡配合。 轴的端部还可以包括可以相对于轴的中心线在径向方向上向外扩展的多个齿轮。 在将转子安装到轴上之后，可以扩大齿轮以消除轴和转子之间的间隙，以形成与转子孔的压配合。

Abstract: A crankshaft assembly for a scroll compressor is disclosed. The crankshaft assembly includes a crankpin having a plurality of apertures therethrough. A crankshaft body has an aperture therethrough. The aperture of the crankshaft and one of the plurality of apertures of the crankpin being aligned when in an assembled state such that in operation fluid flows between the aperture of the crankshaft body and the one of the plurality of apertures of the crankpin. The crankshaft body includes a second aperture aligned with a second of the plurality of apertures of the crankpin. The crankpin and the crankshaft body are separate members. A fastener extends through the second of the plurality of apertures of the crankpin and into the second aperture of the crankshaft body to secure the crankpin and the crankshaft body together in the assembled state.
