Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] Such as figure 2 , image 3 As shown, the compressor pump body structure according to the embodiment of the present invention includes: a crankshaft 1 , an upper flange 5 , a lower flange 3 and a cylinder 7 . The cylinder 7 is installed between the upper flange 5 and the lower flange 3 . Crankshaft 1 passes through upper flange 5 , lower flange 3 and cylinder 7 . The crankshaft 1 includes: a long shaft 13, a short shaft 15 and an eccentric shaft 11 connected between them. Cooperating with the lower flange 3, the short shaft 15 has a first mating surface, which is a rotating surface capable of carrying axial loads. The rotating surface can be in various suitable shapes, including spherical surfaces, conical surfaces, and various regular and The irregular rotating surface only needs to be able to have axial contact with the...

Abstract

The invention provides a pump body structure of a compressor and a compressor with the same, wherein the pump body structure of the compressor comprises a crankshaft and a lower flange. The crankshaft comprises a long shaft, a short shaft and an eccentric shaft, the eccentric shaft is connected between the long shaft and the short shaft, the short shaft is provided with a first matching surface, the lower flange is provided with a second matching surface matched with the first matching surface, and the first matching surface is a rotating surface capable of bearing an axial load. The invention further provides a compressor comprising the pump body structure. Through the pump body structure and the compressor, problems of mechanical loss, noises, vibrations and the like are solved by the elimination of capsizing moment and the realization of automatic alignment; on the foundation, an oil pipeline is designed, thus the lubrication between kinematic pairs is increased, the abrasion is reduced, and the axial structure of the compressor is more compact; therefore, the effect of improving the reliability and the performances of the compressor is achieved.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a compressor pump body structure and a compressor with the pump body structure. Background technique [0002] Such as figure 1 As shown, in the existing pump body structure of the rotary roller compressor, the cylinder 7 is installed between the upper flange 5 and the lower flange 3 . Crankshaft 1 passes through upper flange 5 , lower flange 3 and cylinder 7 . The crankshaft 1 includes: a long shaft 13, a short shaft 15 and an eccentric shaft 11 connected therebetween, wherein the long shaft 13 and the short shaft 15 are arranged coaxially, and the axis of the eccentric shaft 11 is different from the long shaft 13 or the short shaft 15. The cooperation between crankshaft 1 and lower flange 3 adopts the cooperation mode of shaft and bearing bush, which belongs to the cooperation mode of cylindrical sliding bearing. During the operation of the pump body structure (abbreviated as the pu...
