Embodiment Construction

[0035] Hereinafter, a reciprocating compressor and a refrigeration apparatus having the same according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0036] Such as figure 1 As shown, the reciprocating compressor according to the present invention may include a motor unit 100 and a compression unit 200, the motor unit 100 is installed inside the closed container 1 and performs a rotary motion, the compression unit 200 is arranged above the motor unit 100 and received from the motor unit 100 rotational force to compress the refrigerant.

[0037]The motor unit 100 may be implemented as a fixed speed motor capable of forward rotation, a fixed speed motor capable of forward and reverse rotation, or an inverter motor. The motor unit 100 may include a stator 110 and a rotor 120 , the stator 110 is elastically installed in the closed container 1 and supported by a cylinder block 210 (explained later), and the roto...

Abstract

Disclosed are a reciprocating compressor and a refrigerating apparatus having the same, a ball bearing (300) can be easily stably installed between thrust surfaces (213, 227) of a cylinder block (210) and a crank shaft (220) so as to enhance efficiency of the compressor. Also, a ball bearing (300) can be installed by being inserted into thrust surfaces (213, 227) so to shorten a moment arm that much, thereby decreasing a frictional loss at a journal bearing surface (215), resulting in an energy efficiency of the reciprocating compressor and the refrigerating apparatus having the same. In addition, as an oil hole (226c) of the crank shaft (220) is veiled by the journal bearing surface (215) of the cylinder block (210), even if a ball bearing (300) is employed, oil leaked between the thrust surfaces (213, 227) can be reduced, thereby further enhancing the efficiency of the compressor and the refrigerating apparatus having the same.

Description

technical field [0001] The present invention relates to a reciprocating compressor and a refrigerating device having the reciprocating compressor, more particularly, to a reciprocating compressor with a ball bearing installed between a cylinder block and a thrust surface of a crankshaft. machine, and a refrigeration device with the reciprocating compressor. Background technique [0002] Generally speaking, a hermetic compressor is a compressor provided with a motor unit and a compression unit, wherein the motor unit is placed in a closed container for generating driving force, and the compression unit receives the driving force from the motor unit And run. Hermetic compressors may be classified into a reciprocating type, a rotary type, a vane type, and a scroll type according to a compression mechanism regarding refrigerant as a compressible fluid. [0003] A reciprocating compressor is configured as follows: a crankshaft is coupled to the rotor of the motor unit, a connec...
