Embodiment Construction

[0037] The compressor 1 comprises: a motor 2 comprising two main components, namely a stator 3 and a rotor 4; a crankshaft 5 which transmits the motion received from the motor 2; a cylinder block 7 and a cylinder block for radially supporting the crankshaft 5 7 on the bearing 8; and the oil suction pipe 6, which is fixed on the end of the crankshaft 5 for oil suction.

[0038] In the compressor 1 of the present invention, the rotor 4 is fixed on the oil suction pipe 6 without contacting the crankshaft 5 ( figure 2 ). The rotor 4 is preferably fixed on the oil suction pipe 6 by press-fitting so that it is only mechanically connected to the oil suction pipe 6 . Thus, through the oil suction pipe 6 to which the rotor 4 is fixed, the rotational movement of the rotor 4 is transmitted to the crankshaft 5 which is not in contact with the rotor 4 .

[0039] When the crankshaft 5 is fixed in place, the rotor 4 is mounted coaxially on the oil suction pipe 6 . The assembly of the rot...

Abstract

The present invention relates to a compressor (1) comprising a motor (2) composed of two main components, a stator (3) and a rotor (4), a crankshaft (5) that transmits the motion received from the motor (2) and an oil suction pipe (6) secured to the end of the crankshaft (5) for aspirating the oil that prevents the friction and heating of the movable components in the compressor (1).

Description

【Technical field】 [0001] The invention relates to a compressor which is easy to produce. 【Background technique】 [0002] In household appliances, preferably in cooling equipment, the circulation of refrigerant for cooling is provided by a compressor 1'. In a hermetic compressor 1' used in a cooling plant, a motor 2' comprises two main components, namely a stator 3' and a rotor 4'. The magnetic field generated in the motor 2' rotates the rotor 4', and the crankshaft 5', which is press-fittingly fixed to the rotor 4', also rotates. The rotational motion of the crankshaft 5' is transmitted to the pistons through the piston rod and crank pin, providing the reciprocating motion of the pistons. The compressor 1' also includes an oil suction pipe 6' ( figure 1 ). [0003] However, during the production of the compressor, some difficulties are encountered in fixing the rotor press-fittingly on the crankshaft. During the pressing process, the rotor air gap must be properly adjus...
