Abstract
The reciprocating compressor is made with yoke units which connect opposite pairs of pistons while eliminating play between the yoke units and sliding block. Each yoke unit includes a pair of shoes which are removably secured to the pistons and which are adapted to guide the sliding block moved by a crankshaft. Each yoke unit also includes a clamp ring which surrounds the shoes and which biases the shoes towards the sliding block. The shoes are removably secured to the pistons to permit the yoke unit to be readily disassembled. Bow-shaped clamping members may also be employed within each yoke unit to further bias the clamp ring against the shoes.
Claims13
A self-supporting mounting unit for a reciprocating compressor comprising
- at least a pair of pistons disposed on a common axis;
- a sliding block disposed between said pistons for movement transversely of said axis, said block having a pair of mutually parallel flat guide surfaces perpendicular to said axis;
- a pair of shoes, each shoe being secured to a respective piston and disposed between a respective piston and said block, each shoes having a flat guide surface facing a respective flat guide surface of said block and a cylindrical support surface;
- and
- at least one elastically deformable supporting clamp ring surrounding said shoes and said block for biasing said shoes towards said block and parallel to said axis under a prestress, said ring being disposed on said cylindrical support surface of each shoe.
A self-supporting mounting unit for reciprocating compressor comprising
- at least a pair of pistons disposed on a common axis;
- a sliding block disposed between said pistons for movement transversely of said axis;
- a pair of shoes, each shoe being removably secured to a respective piston and disposed between a respective piston and said block, each shoe having a flat guide surface facing a respective flat guide surface of said block and a cylindrical support surface;
- and
- means bearing on said cylindrical support surface of each shoe and biasing said shoes under a prestress towards said block and parallel to said axis.
A reciprocating compressor comprising
- at least one pair of cylinders disposed on a common axis;
- at least a pair of pistons, each piston being reciprocally mounted in a respective cylinder on said axis;
- a sliding block disposed between said pistons on said axis;
- a crankpin disposed in said block for moving said block transversely of said axis;
- a pair of shoes, each shoe being secured to a respective piston and disposed between a respective piston and said block, each shoe having a guide surface facing said block;
- a linear rolling bearing system disposed between said block and a respective shoe;
- a pair of lateral stops for limiting motion of said bearing system relative to said respective shoe;
- at least one elastically deformable supporting clamp ring surrounding said shoes and said block for biasing said shoes towards said block and parallel to said axis under a prestress;
- and
- a pair of clamping members disposed within said clamp ring, each clamping member being disposed against said shoes in bridging relation to said block and having said lateral stops thereon.
A reciprocating compressor comprising
- at least one pair of cylinders disposed on a common axis;
- at least a pair of pistons, each piston being reciprocally mounted in a respective cylinder on said axis;
- a sliding block disposed between said pistons on said axis;
- a crankpin disposed in said block for moving said block transversely of said axis;
- a pair of shoes, each shoe being removably secured to a respective piston and disposed between a respective piston and said block, each shoe having a guide surface facing said block;
- at least one clamp ring means bearing on and biasing said shoes under a prestress towards said block and parallel to said axis;
- and
- a pair of clamping members disposed within said clamp ring, each clamping member being disposed against said shoes in bridging relation to said block for biasing said clamp ring outwardly of said axis.
