Abstract
A compressor may include a shell, a crankshaft, a piston and a connecting rod. The shell may define a cylinder. The crankshaft is supported for rotation relative to the shell. The piston reciprocates within the cylinder in response to rotation of the crankshaft. The piston and the cylinder define a compression chamber therebetween. The connecting rod includes a first bushing rotatably coupled to the piston and a second bushing rotatably coupled to the crankshaft. The second bushing may include a driving surface contacting the crankshaft and having a recess formed therein. The recess receives an insert.
Claims23
A compressor comprising:
- a shell defining a cylinder;
- a crankshaft supported for rotation relative to said shell;
- a piston reciprocating within said cylinder in response to rotation of said crankshaft, said piston and said cylinder defining a compression chamber therebetween;
- and
- a connecting rod including a first bushing rotatably coupled to said piston and a second bushing rotatably coupled to said crankshaft, said second bushing including a driving surface contacting said crankshaft and having a recess formed therein, said recess receiving an insert.
A reciprocating compressor comprising a crankshaft, a piston reciprocating within a cylinder in response to rotation of said crankshaft, and a connecting rod, said piston and said cylinder defining a compression chamber therebetween, said connecting rod including a first bushing coupled to said piston and a second bushing coupled to said crankshaft, said first and second bushings each including a driving surface formed of a first material, said first bushing contacting a piston pin, said second bushing contacting said crankshaft, said driving surface of one of said first and second bushings having a recess formed therein in which an insert is received, said insert being formed from a second material.
A compressor comprising an insert received in a recess in a surface contacting a crankshaft connected to a piston by a connecting rod, wherein said piston reciprocates within a cylinder upon rotation of said crankshaft, said piston and said cylinder defining a compression chamber.
