Problems solved by technology

However, in some cases, due to the limited space in the recess of the main bearing housing, it is difficult to arrange the counterweight so that the centrifugal force of the counterweight is on the same plane as the driving force exerted by the eccentric pin of the drive shaft, which causes the bushing and / or the counterweight creates a bending moment
Moreover, in the case where the counterweight is arranged at an axial position consistent with the orbiting scroll hub, it tends to result in lengthening of the eccentric pin and thus lengthening of the axial dimension of the entire compressor.

Embodiment Construction

[0035] The following descriptions of the embodiments are merely exemplary and in no way limit the present invention and its application or use.

[0036] The same reference numerals are used to denote the same components in the respective drawings, and thus the configurations of the same components will not be described repeatedly.

[0037] First, refer to figure 1 with figure 2 A scroll compressor and a counterweight thereof according to the related art are described.

[0038] see figure 1 The scroll compressor 10 generally includes a casing 110, a top cover 112 arranged at one end of the casing 110, a bottom cover 114 arranged at the other end of the casing 110, and a bottom cover 114 arranged between the top cover 112 and the casing 110 so that the compressor The internal space is divided into a high-pressure side and a low-pressure side by a partition 116 . A high pressure side is formed between the partition 116 and the top cover 112 , and a low pressure side is forme...

Abstract

The invention relates to a scroll compressor (100). The scroll compressor comprises a dynamic vortex piece (160), a drive shaft (130) and linings (400, 400a and 400b). The dynamic vortex piece (160) comprises a handle portion (163). The drive shaft (130) comprises eccentric concave portions (132, 132a and 132b). The handle portion (163) is installed in the eccentric concave portions (132, 132a and132b) in a matched manner through the linings (400, 400a and 400b) to enable the dynamic vortex piece (160) to be driven by the drive shaft (130). The scroll compressor (100) further comprises a counterweight (600). The counterweight (600) is installed on the linings (400, 400a and 400b). Under a high-rotation-speed working condition, the scroll compressor can be safe and reliable, and the scrollcompressor is compact in structure and lowers noise.

Description

technical field [0001] The present invention relates to a scroll compressor. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] For scroll compressors (especially variable speed scroll compressors), especially under high-speed operating conditions, the contact force between the scroll blades contacting the wall will increase due to the increase of the centrifugal force of the movable scroll. Therefore, it is necessary to set a counterweight to counteract the centrifugal force of part of the movable scroll. For example, a counterweight may be provided at an axial location coincident with the orbiting scroll hub (such as connected to a bushing). However, in some cases, due to the limited space in the recess of the main bearing housing, it is difficult to arrange the counterweight so that the centrifugal force of the counterweight is on the same plane a...
