Vane assembly, compressor and air conditioner

Abstract

The invention provides a sliding vane assembly, a compressor and an air conditioner. The sliding vane assembly includes: a sliding vane body; a needle roller groove is arranged on the sliding vane body, and needles are installed in the needle roller groove; At least one end of the groove wall is provided with a limit structure, the limit structure is used to limit the needle roller in the needle roller groove; the slide body is also provided with a cutout, and the cutout is used to remove the needle roller groove at the place where the limit structure is not set. The groove wall reduces the contact area between the needle roller groove and the needle roller. The slide assembly of the present invention reduces the resistance effect of the inner wall of the needle groove to the rolling of the needle, improves the rolling efficiency of the needle, reduces the rolling friction force between the slide and the roller, and reduces the friction loss of the needle. The new ceramic needle roller improves the wear resistance and self-lubricating performance, and avoids the occurrence of adhesive wear between the sliding plate, needle roller and roller. The diamond-like graphite-nitride composite coating in the needle groove has good self-lubrication and strong wear resistance, which improves the long-term operation reliability of the slide.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a sliding vane assembly, a compressor and an air conditioner. Background technique [0002] The rotary compressor used in the existing air conditioning system has a large friction loss, accounting for about 8% of the total power consumption of the system, of which the friction loss between the sliding plate and the roller accounts for 2% to 6% of the total friction loss . Moreover, the friction between the sliding plate and the roller in the traditional rotor compressor is the sliding friction of line contact. Although the friction force of line contact is not as large as that of surface contact, the friction force of line contact is also greater than that generated by rolling friction. As a result, the wear of the friction pair formed by the sliding vane and the roller is serious, resulting in poor sealing performance of the compressor, reduced energy efficiency...

Moreover, the friction between the sliding plate and the roller in the traditional rotor compressor is the sliding friction of line contact. Although the friction force of line contact is not as large as that of surface contact, the friction force of line contact is also greater than that generated by rolling friction. Much more, which in turn leads to serious wear of the friction pair formed by the sliding vane and the roller, resulting in poor sealing of the compressor, reduced energy efficiency of the compressor, or even failure
