Embodiment Construction

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0023] see figure 1 and figure 2 , The compressor according to the present invention includes: a crankshaft 6; an upper flange 9 sleeved on the crankshaft 6; a lower cover plate 1 sleeved on the crankshaft 6, and a flexible groove 10 is provided on the lower cover plate 1. A flexible groove is set on the lower cover to reduce the stress concentration, increase the elastic deformation between the crankshaft and the bearing structure, reduce the contact stress concentration between the crankshaft and the bearing, and reduce the impact force, thereby reducing the noise peak and finally reducing the noise level Overall decibel value.

[0024] The compressor also includes a bearing structure, which is arranged on the lower cover plate 1 . The flexibl...

Abstract

The invention provides a compressor. The compressor includes a crankshaft, an upper flange sleevedly arranged on the crankshaft, a lower cover plate sleevedly arranged on the crankshaft through a bearing structure, and a flexible slot arranged on the bearing structure. According to the compressor, the flexible slot is arranged on the lower cover plate, so that the stress concentration is reduced, the amount of elastic deformation between the crankshaft and bearing structure is improved, the contact stress concentration between the crankshaft and a bearing is reduced, the impact force is reduced, and thus the noise peak value is reduced, and the overall decibel value of noise is eventually reduced.

Description

technical field [0001] The present invention relates to the field of compressors, in particular, to a compressor. Background technique [0002] In the prior art, in order to solve the problem of high vibration and noise in the operation of the current compressor, a flexible groove is provided on the lower flange, and the lower cover plate is a flat plate structure. Due to the low strength of the powder metallurgy material used in the lower flange, it is difficult to install it on the lower flange. Open a flexible groove that meets the requirements, and the use of cast iron will reduce the processing efficiency. At the same time, the non-processed surface of the cast iron material is prone to burrs, residues, scales and other impurities falling off, and if they fall off the surface of the cast iron lower flange, they may enter the cylinder. , causing the compressor to be stuck and reducing the reliability of the compressor. [0003] However, the comprehensive cutting process...
