Abstract
A reciprocating type compressor may include a crank shaft that is coupled to a rotor of a motor to receive a rotational force and a connecting rod that is coupled to a pin of the crank shaft and converts a rotational force of the crank shaft into a linear motion of a piston. The connecting rod may include a first end having a tubular body that includes a pin insertion hole into which the pin of the crank shaft is inserted and a socket that projects from the tubular body, a second end coupled with the piston, and a main body that extends between the first end and the second end and having a ball that is received inside of the socket.
Claims20
A reciprocating type compressor, comprising:
- a crank shaft configured to be coupled to a rotor of a motor to receive a rotational force of the motor;
- a connecting rod configured to be coupled to a pin of the crank shaft to convert the rotational force of the crank shaft into a linear motion of a piston, wherein the connecting rod comprises:
- a first end that includes a tubular body having a pin insertion hole into which the pin of the crank shaft is inserted and a socket that projects from the tubular body;
- a second end formed at an opposite side of the first end and configured to be coupled with the piston;
- and
- a main body that extends between the first end and the second end and includes a ball configured to be received in the socket.
A reciprocating type compressor, comprising:
- a motor comprising a stator that is supported by a frame inside of a hermetic container, and a rotor that rotates inside of the stator;
- and
- a compression assembly that is installed in an upper side of the motor and receives a rotational force from the rotor to compress a refrigerant, wherein the motor and compression assembly collectively comprise:
- a crank shaft configured to be coupled to the rotor to transfer a rotational force of the motor to the crank shaft;
- and
- a connecting rod configured to be coupled to a pin of the crank shaft and convert the rotational force of the crank shaft into a linear motion of a piston, wherein the connecting rod comprises:
- a first end including a tubular body that includes a pin insertion hole through which the pin of the crank shaft is configured to be inserted and a socket that projects from the tubular body;
- a second end configured to be coupled to the piston;
- and
- a main body that extends between the first end and the second end and having a ball configured to be received inside of the socket.
A reciprocating type compressor, comprising:
- a crank shaft configured to be rotated by a motor and including an oil passage and a pin;
- a shaft connector configured to be connected to the crank shaft, the shaft connector including a tubular body into which the pin is configured to be inserted and a socket that extends from an outer circumferential surface of the tubular portion;
- a connecting rod configured to be connected to the shaft connector and including a first end comprising a ball that is inserted into the socket to create a ball joint;
- and
- a piston configured to be connected to a second end of the connecting rod opposite the ball, wherein the oil passage allows oil to flow into the ball joint.
