Embodiment 1

[0029] This embodiment describes the main bearing mechanism of the present invention in detail.

[0030] The main bearing mechanism of this embodiment includes a bearing assembly and an oil pool assembly. Among them, the bearing assembly includes at least two sections of main bearings, and at least two sections of main bearings are separated; the oil pool assembly includes at least two oil pools, and the number of oil pools is not less than the number of main bearings, and each section of main bearing The bearings can be lubricated by lubricating oil in at least one oil sump. Preferably, each section of the main bearing can be lubricated by lubricating oil in one oil pool, or lubricated by lubricating oil in two or more oil pools.

[0031] The main bearing mechanism of this embodiment includes a bearing assembly and an oil pool assembly, wherein the bearing assembly includes at least two sections of main bearings, and at least two sections of main bearings are arranged separa...

Embodiment 2

[0041] The compressor of this embodiment includes the main bearing mechanism of any technical solution in Embodiment 1. Preferably, the compressor in this embodiment is a scroll compressor. More preferably, the compressor in this embodiment is a scroll compressor used in air conditioners or heat pumps.

[0042] The remaining parts of the scroll compressor are the same as the existing scroll compressor. Such as figure 2 As shown, the scroll compressor of this embodiment is mainly composed of a motor 6, an upper bracket 4, a lower bracket 11, a fixed scroll 1, a movable scroll 18, an Oldham slip ring 17, a crankshaft 7, and the like. The movable scroll 18 and the fixed scroll 1 are installed opposite to each other on the upper bracket 4 with a phase angle difference of 180°. The movable scroll 18 moves under the drive of the crankshaft 7 and meshes with the fixed scroll 1 to form a series of mutually isolated and continuously changing volumes. The crescent-shaped airtight ca...

Abstract

The invention discloses a main bearing mechanism and a compressor, and relates to the technical field of compressors. The technical problems that the lubrication is insufficient and the operation reliability of the compressor is poor due to the fact that a compressor main bearing is too high in the prior art are solved. The main bearing mechanism comprises a bearing assembly and an oil pool assembly, wherein the bearing assembly comprises at least two sections of main bearings, and the at least two sections of main bearings are arranged in a split mode; and the oil pool assembly comprises at least two oil pools, the number of the oil pools is not smaller than that of the main bearings, and each section of main bearing can be lubricated through lubricating oil in at least one oil pool. According to the main bearing mechanism, by reducing the height of each section of main bearing and performing segmented lubrication on each section of main bearing through the lubricating oil in the oil pools, the lubrication efficiency of each section of main bearing is improved, it is guaranteed that each section of main bearing can be fully lubricated, and therefore the reliability of the compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a main bearing mechanism and a compressor including the main bearing mechanism. Background technique [0002] Scroll compressors are widely used in the fields of refrigeration, air conditioning and heat pumps because of their high efficiency, small size, light weight, and stable operation. Generally speaking, a scroll compressor is composed of a closed shell, a fixed scroll, a movable scroll, a bracket, a crankshaft, an anti-rotation mechanism, an oil supply device, and a motor. The profiles of the fixed scroll and the movable scroll are both spiral, and the movable scroll is eccentrically installed relative to the fixed scroll with a difference of 180°, so multiple crescent-shaped spaces are formed between the movable and static scrolls. When the movable scroll takes the center of the static scroll as the center of rotation and performs non-rotation-translational motion wit...
