Problems solved by technology

[0003] However, the disadvantage of the existing method is that no matter it is a moving scroll or an Oldham slip ring, it is a sliding motion, and the sliding motion has a large friction on the one hand, especially when there is a lack of oil, the friction heats up rapidly, resulting in further friction. If the size is increased, the damage to the components will be aggravated; on the other hand, the noise is high, especially when the vacuum compressor is running at high speed, the reciprocating high-frequency motion of the movable scroll and the Oldham slip ring will cause the vibration of the equipment, resulting in a lot of noise

Embodiment Construction

[0026] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, the scroll vacuum compressor includes a fixed scroll 18, a movable scroll 5 and a crankshaft 1 passing through the base 4, and the fixed scroll 18 and the movable scroll 5 cooperate with each other to form a working chamber. The crankshaft 1 includes a crankshaft front section 101 and a crankshaft rear section 102. The crankshaft front section 101 and the crankshaft rear section 102 are connected by crankshafts. The crankshaft front section 101 has a preset crankshaft eccentricity relative to the crankshaft rear section 102. The movable scroll 5 is installed on the crankshaft 1 At the front end, the movable scroll 5 is connected to the base 4 through the eccentric shaft 10, and the eccentricity of the eccentric shaft section connected to the movable scroll 5 relative to the eccentric shaft section connected to the base 4...

Abstract

The invention relates to a vacuum scroll compressor, in particular to a vacuum scroll compressor which doesn't use a cross ring to limit rotation of a removable scroll pan. The vacuum scroll compressor comprises the removable scroll pan and a crankshaft penetrating through the base, wherein the crankshaft comprises a front crankshaft section and a rear crankshaft section, the front crankshaft section has preset crankshaft eccentricity relative to the rear crankshaft section, the removable scroll pan is mounted at the front end of the crankshaft and connected with the base through an eccentric shaft, and the eccentricity and the rotation angle vector of an eccentric shaft section connected with the removable scroll pan relative to the eccentric shaft section connected with the base are equal to the preset crankshaft eccentricity and the rotation angle vector of the front crankshaft section relative to the rear crankshaft section. According to the vacuum scroll compressor, equipment vibration and noise are reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a scroll vacuum compressor, in particular to a scroll vacuum compressor which does not need an Oldham ring to restrict the rotation of a movable scroll. Background technique [0002] The vacuum compressor has both the functions of a vacuum pump and a compressor. The scroll vacuum compressor forms a compression cavity through the cooperation of the movable scroll and the fixed scroll, and realizes the function of compression or vacuum through the change of the volume of the compression cavity. The existing scroll vacuum compressor structure includes a casing, a base is arranged on the upper part of the casing, the fixed scroll is arranged on the upper part of the base, and is usually fixedly connected with the base, and the movable scroll is arranged below the fixed scroll and on the base. Above the seat, it cooperates with the static scroll to form a compression chamber. The middle part of the movable scroll is connected to a c...
