Abstract: A compressor according to the present disclosure may include a bearing member located out of a range in an axial direction of a rotor. Accordingly, the bearing member and the rotor cannot overlap each other so as to reduce a bearing area. This may result in reducing a frictional loss of the compressor and ensuring a press-fit length of the rotor, so as to prevent interference between the rotor and a stator. Also, an area of an oil passage can be increased without an increase in the frictional loss, resulting in an increase in an amount of oil supplied.
Abstract translation: 根据本公开的压缩机可以包括位于转子的轴向范围之外的轴承构件。 因此，轴承构件和转子不能相互重叠，以减小承载面积。 这可能导致减小压缩机的摩擦损失并确保转子的压入长度，以防止转子和定子之间的干扰。 此外，可以增加油路的面积而不增加摩擦损失，导致供油量的增加。

Abstract: A compressor is provided that is configured to suspend a compressor assembly from a string to significantly expand a speed range in which the compressor may be operated. The compressor may include a shell, and a compressor assembly disposed in the shell. The shell and the compressor assembly may be connected to each other by a string. The compressor assembly may be suspended from the shell by the string, and a tensile force may be generated at the string due to self-weight of the compressor assembly. A frame of the compressor assembly may not directly contact the shell.

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.

Abstract: A motor assembly for compressing a fluid by causing a rotational shaft to reciprocate by providing a drive force to the rotational shaft, and a reciprocating compressor including a motor assembly are provided. The motor assembly may include a cylinder block in which a bore is formed and which is penetrated by the rotational shaft, a stator coupled to the cylinder block, a rotor installed at an outer circumferential surface of the stator so as to be rotated by the stator and which is coupled to the rotational shaft so as to rotate together with the rotational shaft, and at least one fastening member that fastens the stator and the cylinder block to each other such that the stator is supported by the cylinder block.
