Embodiment Construction

[0027] figure 1 A sectional view of a hermetic refrigeration compressor 1 is shown. The refrigeration compressor 1 comprises a closed casing 2 and a compressor unit 3 . The compressor unit 3 comprises a compressor block 4 and an electric motor 5 in the form of an outer rotor motor with an inner arranged stator 6 and an outer arranged rotor 7 . The rotor 7 is connected to a shaft 8 , and the shaft 8 is supported by the compressor body 4 through radial bearings 9 . The shaft 8 drives an eccentrically mounted crank pin 10 , which is connected with a piston-cylinder unit 12 by means of a connecting rod 11 .

[0028] Compressor unit 3 is axially connected to housing 2 via spring elements 13 , 14 , referred to below as support springs. The support springs 13, 14 accept the weight of the compressor unit 3. Due to the sectional view, only two support springs 13 , 14 can be seen. However, a total of four support springs 13 , 14 are provided.

[0029] Each support spring 13 , 14 i...

Abstract

The compressor (1) has a closed housing (2) in which a compressor unit (3) is provided. The compressor unit has a compressor block (4) and an electric motor (5) which comprises a rotor (7) that is rotatable about a rotation axis. Two safety elements (17,18) are symmetrically arranged for restricting rotational vibrations between the housing and the compressor unit. The security elements are spaced apart from the axis of rotation of rotor.

Description

technical field [0001] The invention relates to a refrigeration compressor with a closed casing, in which a compressor unit is arranged, the compressor unit comprising a compressor body and an electric motor comprising a stator and a rotor rotating around an axis of rotation. Background technique [0002] Such refrigeration compressors are also called hermetic refrigeration compressors. For example, they are used in refrigeration equipment like refrigerators or freezers. In this regard, a small refrigerant compressor component height is required. Further, energy consumption should be as small as possible. [0003] The reduction in energy consumption is achieved because better insulation is used for refrigeration equipment and refrigeration compressors operating at lower or variable speeds. In this regard, it is known to suppress vibrations by elastically supporting the compressor unit in the casing. In order to prevent resonances, also in connection with low speeds, the ...
