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.
In a machine having a reciprocable member therein, a bearing for said member comprising a slidable member with pivot means disposed substantially centrally of its ends and having a bearing surface elongated in the direction it moves for engaging a mating fixed surface in the machine, said elongated surface having at least one transverse groove therein concentric with respect to a plane through the center of the pivot means and perpendicular to the bearing surface to cause the moments of force acting thereon about its pivot when in motion to cause the leading end thereof to tend to lift off of the mating surface.
In a machine having a reciprocable member therein, an energy-absorbing device operably connected to one end of said member and power means operably connected to the other end thereof, slidable bearing means for said member comprising a pair of bearing members with one at each side of said reciprocable member pivotally connected thereto near the connection between said reciprocable member and one of said energy absorbing device and said power means, said bearing members being adapted to engage a pair of diametrically opposed and mating surfaces in the machine so as to guide the lower end of said reciprocable member during its reciprocating movement.
A machine comprising a housing, an energy absorbing device having a driven member thereof reciprocably mounted therein, a first bearing means detachably mounted in said housing for guiding said member, power driven means detachably mounted in a second bearing means in said housing in spaced relationship with respect to said member, coupling means between said member and said power driven means, third bearing means on said coupling means, and mating fourth bearing means in said housing for engagement by said third bearing means for guidance by said mating means and at least one opening in a side wall of said housing that is large enough to permit the removal of all of said bearing means and other detachble elements in said housing.
