Abstract

Disclosed is a motor fixing structure of a reciprocating compressor comprising: a front frame having a predetermined shape; a middle frame positioned with a certain interval from the front frame; an outer stator positioned between the front frame and the middle frame so that an inner stator can be positioned with a certain interval therein; a coupling means for fixing the outer stator positioned between the front frame and the middle frame by coupling the front frame and the middle frame to each other; and a sliding preventing means installed between the outer stator and the front frame contacting each other and / or between the outer stator and the middle frame contacting each other for preventing sliding. According to this, a motor assembly is simplified, and abrasion and damage of components are prevented by preventing a motor assembly dimension variation during driving.

Description

technical field [0001] The invention relates to a reciprocating compressor, in particular to a motor fixing structure of the reciprocating compressor, which can simplify the assembly of the motor and prevent the assembly dimension from changing after the motor is assembled. Background technique [0002] Generally, a reciprocating compressor is a device that sucks and compresses refrigerant gas according to the reciprocating motion of a piston in a cylinder. Reciprocating compressors can be mainly divided into two categories according to the driving mechanism. One way is to convert the rotation of the motor into linear reciprocating motion and transmit it to the piston, and the other way is to directly transmit the linear reciprocating motion of the motor to the piston. [0003] Figure 1 is a schematic diagram of one embodiment of a reciprocating compressor in which the linear reciprocating motion of the motor is directly transmitted to the piston. As shown in the figure, t...
