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.
Claims17
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, wherein the tubular body includes a first insertion hole through which the ball is configured to pass provided at a side opposite to a side from which the socket projects, and wherein the socket includes a second insertion hole through which the second end and the main body are configured to pass.
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, wherein the tubular body includes a first insertion hole through which the ball is configured to pass provided at a side opposite to a side from which the socket projects, and wherein the socket includes a second insertion hole through which the second end and the main body are configured to pass.
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 body;
- 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, wherein a first insertion hole is formed on the outer circumferential surface of the tubular body opposite the socket and a second insertion hole is formed at a distal end of the socket, and wherein the connecting rod is configured to be inserted through the first and second insertion holes such that the ball is inserted into the socket to create the ball joint.
