Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0031] Please refer to Figure 2 to Figure 11 , The present invention provides a compressor crankshaft support structure, which can better lubricate the crankshaft support structure.
[0032] exist figure 2 In the compressor shown, the compressor includes a casing 1 , a support portion and a crankshaft 3 . Wherein, the support portion is fixedly arranged in the housing 1, wherein a bearing hole 5 is provided on the support portion, so that one end of the crankshaft 3 is supported in the bearing hole 5 in a pivotable manner, and is connected with the bearing hole 5 A friction pair is formed between them. Such as figure 2 As shown, a cavity 6 is surrounded between the end of one end of the crankshaft 3 and the supporting part. In particular, the friction pair may not only be a sli...

The invention discloses a compressor and a compressor crankshaft supporting structure. The compressor crankshaft supporting structure comprises a shell, a supporting part and a crankshaft, wherein the supporting part is fixed in the shell and comprises a bearing hole, one end of the crankshaft is supported in the bearing hole in a pivoted mode and forms a friction pair along with the bearing hole, and a cavity is defined between the tip of one end of the crankshaft and the supporting part. The compressor crankshaft supporting structure further comprises a lubricating runner extending along the friction pair. A central hole of the crankshaft communicates with an inner cavity of the compressor sequentially though the cavity and the lubricating runner. The friction pair can be lubricated through the lubricating runner, and therefore lubrication is achieved after a support part is added to the upper end of a motor, abrasion is avoided, the service life is prolonged, and the reliability is improved. The compressor and the compressor crankshaft supporting structure have the characteristics of being simple in structure and low in cost.
Description
technical field [0001] The invention relates to the field of compressors, in particular to a compressor and a compressor crankshaft support structure. Background technique [0002] At present, some compressors have a support structure added to the upper end of the motor, but no corresponding lubricating structure is provided, which makes the support structure easy to wear and has low reliability. [0003] For example, figure 1 A structural schematic diagram of a compressor using a support structure is shown. Such as figure 1 As shown, the housing 1 of the compressor is provided with a bracket 2 , a bearing housing 26 , a bearing 25 , a crankshaft 3 , a motor stator 17 and an electronic rotor 16 . Wherein, the upper end of the crankshaft 3 is supported on the bearing housing 26 through the bearing 25 . Through this structure, the shaking of the crankshaft 3 and the electronic rotor 16 during operation can be reduced, and the rigidity can be enhanced. However, the positio...
