Abstract

A machine, such as the compressor, having a housing formed in two sections. One section encloses a working unit while the second section encloses a driving unit for operating the working unit. A connector unit in the second section is operably connected by removable bearing means to the working unit and to the driving unit. The connector unit has pivoted bearings thereon that are slidable on mating removable bearings on the housing. A window is provided in the second section, through which window all of the bearing means in the second section may be removed without disturbing the working unit in its section. The pivoted bearings are of the so called Mitchell type but are of an improved construction. The bearing surfaces thereof have one or more transverse grooves therein that are symetrically arranged with respect to a plane passing through the pivot bore and perpendicular to the bearing's face. This construction tends to prevent digging in of the bearing when moving along the mating bearing.
