Shoes 50 are removable and can be replaced as needed. By mounting cross head shoes 50 on shoe support 32 , the surfaces of the shoe support are protected from damage and only the shoes need to be replaced in the event of surface wear. Hence, the replaceable shoes will protect frame 14 from any primary damage caused by the motion of cross head on the shoes. In certain embodiments, cross head shoe supports 32 have access openings that allow for the removal and replacement of shoes 50 without removing cross head 52 .

Abstract
Description
- The present invention relates generally to reciprocating compressors. More particularly, the present invention relates to horizontally-opposed reciprocating compressors. Still more particularly, the present invention relates to the structural frame that supports the crankshaft of a horizontally opposed reciprocating compressor.
- Reciprocating compressors are positive-displacement pumps that pressurize a fluid by moving, or stroking, a piston axially within a cylinder. In horizontally-opposed reciprocating compressors, the pistons are connected, via cross heads and connecting rods, to a crankshaft that is rotated by an external power source. The pistons are positioned horizontally and arranged in pairs opposed at different planes across the crankshaft. In conventional applications, the crankshaft is supported within a frame that supports the reciprocating loads, coupled moments, and torque on the crankshaft.
- Most standard frames have a generally rectangular cross-section with vertical walls cantilevered from a heavy base. In order to minimize flexion and distortion of the vertical walls, the walls are generally very thick and interconnected at their tops by a plurality of high-strength tie bars. These tie bars must be made to very tight tolerances as any variations in length can have a major impact on the assembly of the tie bars. Further, as the capacity, speed, and pressure of a compressor increases, the size and weight of the frame also increases in order to manage the increased reciprocating loads, coupled moments, and torque.
- Thus, there remains a need to develop methods and apparatus for supporting reciprocating machinery, which overcome some of the foregoing difficulties while providing more advantageous overall results.
- The embodiments of the present invention are directed toward methods and apparatus for a reciprocating compressor barrel frame comprising a continuous curved wall having an inner surface and an outer surface. A housing is formed by the inner surface of the curved wall. A pair cross head shoe supports extend from the outer surface of said curved wall in opposite directions perpendicular to said housing. A plurality of bearing support members are disposed within the housing and supported by the curved wall. The bearing support members are arranged so as to support a crankshaft disposed within the housing. A base flange is connected to the curved wall and is operable to attach to a structure that will support the frame.
- In certain embodiments, a reciprocating compressor comprises a crankshaft and a plurality of cross heads coupled to the crankshaft via connecting rods. The compressor also comprises a frame comprising a continuously curved wall that encloses the crankshaft that is rotatably mounted within the frame. A plurality of cross head shoe supports extend from and are formed integral to the curved wall of the frame. Each cross head is supported by cross head shoes that are removably connected to the cross head shoe supports. A plurality of bearing support members are disposed within the housing and are supported by the curved wall. A plurality of bearings are disposed between the crankshaft and the plurality of bearing support members. A lubricant sump is disposed within the housing and arranged so as to lubricate the crankshaft.
- Thus, the present invention comprises a combination of features and advantages that enable it to overcome various problems of prior devices. The various characteristics described above, as well as other features, will be readily apparent to those skilled in the art upon reading the following detailed description of the preferred embodiments of the invention, and by referring to the accompanying drawings.
- For a more detailed description of the preferred embodiment of the present invention, reference will now be made to the accompanying drawings, wherein:
-
FIG. 1 is a view of a reciprocating compressor including a frame constructed in accordance with embodiments of the invention; -
FIG. 2 is a partial sectional end view of a reciprocating compressor including a frame constructed in accordance with embodiments of the invention; -
FIG. 3 is an partial sectional isometric view of a frame constructed in accordance with embodiments of the invention; -
FIG. 4 is an end view of the frame ofFIG. 3 ; and -
FIG. 5 is a sectional end view of a cross head disposed in a frame constructed in accordance with embodiments of the invention. - Referring now to
FIGS. 1 and 2 , reciprocatingcompressor 10 comprisesframe 14,crankshaft 16, connectingrods 18, cross heads 20,pistons 22,cylinders 24, andvalve assemblies 26. A power supply is coupled to one end ofcrankshaft 16 and provides the power to rotate the crankshaft.Crankshaft 16 is supported withinframe 14.Connecting rods 18 couple cross heads 20 andpistons 22 tocrankshaft 16.Pistons 22 move linearly withincylinders 24.Valve assemblies 26 control flow into and out ofcylinders 24. - As
crankshaft 16 is rotated by a power supply, connectingrods 18 and cross heads 20 transform the rotational motion of the crankshaft into linear movement ofpistons 22 withincylinders 22. Aspistons 22 stroke forward withincylinders 24, the pressure within the cylinder increases until discharge valves invalve assembly 26 open to allow pressurized fluids to exit the cylinder. Aspistons 22 stroke backward, the pressure within thecylinders 24 decreases and an inlet valve invalve assembly 26 opens to allow fluid to fill the cylinder.Crankshaft 16 is arranged such that while one piston strokes forward the piston on the opposite side of the crankshaft strokes backward. While this arrangement helps maintain balance, the coupled moments, which are formed by the variation of plane of action of the pistons' operation, are transferred by thecrank shaft 16 and are supported by the frame ofcompressor 10. - Regardless of the efforts taken to balance
crankshaft 16, there will be some unbalanced forces andcompressor 10 will be subject to vibratory reciprocating loads. By supportingcrankshaft 16 and all of the other moving components,frame 14 will be subjected to the reciprocating loads, coupled moments, and torque on the crankshaft and has to be able to withstand those loads without excessive distortion. In order to improve the distribution of the reciprocating loads, coupled moments, and torque as well as the distortion of the frame itself,frame 14 is a “barrel”-type frame comprising a continuous,curved wall 28 that forms acrankshaft housing 30. -
Curved wall 28 surroundscrankshaft 16 such that the loads generated in a plurality of directions by the movement of the crankshaft and the reciprocating actions of the piston assemblies are transferred to the wall. Becausewall 28 is continuously curved, every element of the wall is supported by adjacent elements within the wall and the curved wall is effectively self-supported against these loads in a plurality of directions. Therefore, no external tie bars are necessary to support and balance the reciprocating loads as are found in the existing art.Curved wall 28 also improves the efficiency with which the reciprocating loads, coupled moments, and torque are dissipated, thus allowing a reduction in wall thickness, and hence a reduction in the weight offrame 14 versus a conventional box-type frame. - Referring now to
FIGS. 3 and 4 , barrel-type frame 14 integrally comprisescurved wall 28,housing 30, cross head shoe supports 32,base flange 34,end flanges 36, bearing supports 38,lubricant sump 40,access openings 42, andarcuate wall portions 60.Frame 14 is shown as having two cross heads, but multiple pairs of cross heads are possible.Frame 14 may be constructed from a single casting that is machined to include desired features. Constructingframe 14 from a single piece of material eliminates welding and other high-temperature processes that may distort the frame. Furthermore Frame 14 may be constructed with plurality of ribs formed betweenwall 28,base flange 34, and cross head shoe supports 32 that provide structural rigidity and potentially increase thermal transfer capability of the frame. -
Base flange 34 is a flat, rectangular member that provides a base suitable for attachment to a foundation or other structure that will support the compressor.Base flange 34 may comprise a bolt pattern or other means for securing the compressor.Curved wall 28 extends frombase flange 34 to form substantiallycylindrical housing 30 havingend flanges 36. Althoughcurved wall 28 is illustrated as being substantially cylindrical, other curved shapes are possible and may provide advantages in certain applications. -
Housing 30 provides an enclosure adapted to receive a crankshaft and comprisesbearing supports 38,lubricant sump 40,access openings 42, andarcuate wall portions 60. Bearing supports 38 provide mounting and attachment points for bearings that support the crankshaft.Lubricant sump 40 provides a reservoir of lubricant that can be used to lubricate the bearings and crankshaft.Access openings 42 andarcuate wall portions 60 are formed incurved wall 28 ofhousing 30 and extend between cross head shoe supports 32. Each access opening 42 is disposed between an adjacent pair ofarcuate wall portions 60. In the exemplary embodiments illustrated byFIG. 3 , fouraccess openings 42 and threearcuate wall portions 60 are formed incurved wall 28 ofhousing 30.Access openings 42 provide access to the crankshaft and other components installed within the housing. When in operation, access opening 42 as well asend flanges 36 may be covered with simple hinged covers, clamped covers, or other type covers. -
Frame 14 also features cross head shoe supports 32 that are constructed integral withwall 28. Integral crosshead shoe support 32 provides support for each of the shoes and cross head as well as further increase the strength ofwall 28. The integral feature of crosshead shoe support 32 with theframe 14 also allows machining of the crank shaft bore and the cross head shoe support bore with the same machining set up. This eliminates misalignment problems between the cross head with the crank shaft as it is inherent with the conventional separate cross head guide design. Furthermore, the integral design eliminates the extra machining and bolting arrangement which is required by the conventional attachment design. - Cross head shoe supports 32 comprise an
internal cavity 44 shaped to receive cross head and cross head shoe.Cavity 44 may be fitted with a stationarycross head shoe 50, seeFIG. 5 , that provides a precision-machined surface for guiding thecross head 52.Shoes 50 are removable and can be replaced as needed. By mounting cross head shoes 50 onshoe support 32, the surfaces of the shoe support are protected from damage and only the shoes need to be replaced in the event of surface wear. Hence, the replaceable shoes will protectframe 14 from any primary damage caused by the motion of cross head on the shoes. In certain embodiments, cross head shoe supports 32 have access openings that allow for the removal and replacement ofshoes 50 without removingcross head 52. - While preferred embodiments of this invention have been shown and described, modifications thereof can be made by one skilled in the art without departing from the scope or teaching of this invention. The embodiments described herein are exemplary only and are not limiting. Many variations and modifications of the system and apparatus are possible and are within the scope of the invention. For example, the relative dimensions of various parts, the materials from which the various parts are made, and other parameters can be varied, so long as the compressor frame apparatus retain the advantages discussed herein. Accordingly, the scope of protection is not limited to the embodiments described herein, but is only limited by the claims that follow, the scope of which shall include all equivalents of the subject matter of the claims.
