Compressor baseplate with stiffening ribs for increased oil volume and rail mounting without spacers

摘要

A compressor that includes a housing with a plurality of attached shell sections which define an internal volume of the compressor. In the housing, compressor bodies have respective surfaces which mutually engage. The compressor includes a drive unit disposed in the housing. The drive unit has a motor to provide a mechanical output on a drive shaft. The drive shaft drives one of the compressor bodies to facilitate relative movement for the compression of fluid. In an embodiment, the plurality of shell sections includes a base plate having an annular rib, which locates a tubular central shell section of the plurality of attached shell sections.

1. A compressor assembly, comprising:
a housing that includes a plurality of attached shell sections which define an internal volume of the compressor; compressor bodies disposed in the housing, the compressor bodies having respective surfaces which mutually engage; a drive unit disposed in the housing, the drive unit having a motor to provide a mechanical output on a drive shaft, the drive shaft operatively driving the compressor bodies to facilitate relative movement for the compression of fluid; wherein the plurality of shell sections includes a base plate having an annular rib which locates a tubular central shell section of the plurality of attached shell sections; and wherein a central portion of the base plate is generally convex along the outer surface of the housing, and has two pairs of opposing angled sides, with a first pair of opposing angled sides being slightly concave with respect to the central portion, wherein a second pair of opposing angled sides has a generally linear profile when viewed in cross-section, with the second pair of opposing angled sides being shorter and angled steeper than the first pair.
