Problems solved by technology

[0005] In the reciprocating compressor as described above, since the outer stator and the inner stator of the reciprocating motor are fixed to the frame, magnetic flux may flow between the outer stator and the inner stator through the frame, causing magnetic flux leakage.

Embodiment Construction

[0022] Hereinafter, the reciprocating compressor and refrigeration equipment of the present invention will be described in detail with reference to the accompanying drawings.

[0023] like figure 1 As shown, the reciprocating compressor of the present invention includes: a casing 100, which makes the suction pipe SP communicate with the discharge pipe DP; a frame unit 200, which is elastically supported inside the casing 100; a reciprocating motor 300, It is supported by the above-mentioned frame unit 200, so that the rotor 330 described later performs linear reciprocating motion; the compression unit 400 combines the piston 420 described later with the rotor 33 of the above-mentioned reciprocating motor 300, and the compression unit 400 is supported by the above-mentioned frame unit 200. The unit 400 ; a plurality of resonance units 500 elastically support the rotor 330 of the reciprocating motor 300 and the piston 420 of the compression unit 400 along the moving direction to...

Abstract

The present invention relates to a reciprocating compressor. The invention allows a cylinder in which a piston is reciprocated to be inserted and coupled into and with a cylinder unit of a frame for fixing a stator of a reciprocating motor, and is formed with a collision prevention unit for enabling a piston connection part to collide with the cylinder, so that the piston connection part can prevent the collision power from being delivered to the frame having the cylinder unit even though the piston connection part is over-struck, thereby preventing the laminated state of the stator from being distorted. Thus, since the decreased efficiency of the motor is prevented, reliability and performance of the compressor can be increased.

Description

technical field [0001] The invention relates to a reciprocating compressor, in particular to a reciprocating compressor which prevents transmission of impact force and blocks magnetic flux leakage through a cylinder. Background technique [0002] In general, a reciprocating compressor employs a method in which a piston sucks in a refrigerant while performing linear reciprocating motion inside a cylinder, compresses it, and then discharges it. The above-mentioned reciprocating compressor can be divided into connection type and vibration type according to the driving method of its piston. [0003] In the connection-type reciprocating compressor, the piston is connected to the rotating shaft of the rotary electric machine through a connecting rod, and compresses the refrigerant while reciprocating in the cylinder. On the contrary, the vibration-type reciprocating compressor adopts the method that the piston is connected to the rotor of the reciprocating motor, and the piston r...
