Problems solved by technology

Due to the high brittleness of graphite and other self-lubricating materials, low strength, and easy breakage, the sliding friction between the sliding vane and the cylinder, the sliding vane and the rotor groove will generate a lot of heat and make the sliding vane wear seriously, further increasing the possibility of damage

Embodiment Construction

[0012] Such as Figure 1 to Figure 3 As shown, the present invention includes a cylinder 1 and a rotor 4, the rotor 4 is eccentrically installed in the cylinder 1, the rotor 4 is geometrically tangent to the cylinder 1, a crescent-shaped space is formed between the inner wall of the cylinder 1 and the outer surface of the rotor 4, and the rotor 4 is provided with rotor slots 2, and in each rotor slot 2 there is installed a sliding piece 5 that can slide freely in the radial direction, wherein the sliding piece 5 is made of aluminum alloy, its top and bottom and the rotor slot 4 Bearing housings 8 are installed on both sides, and rolling bearings 3 are installed on the bearing housings 8. The bearings 3 are filled with high-temperature resistant lubricants and have sealing rings. The friction between the sliding plate 5 and the inner wall of the cylinder 1 and the rotor 4 is rolling friction.

Abstract

The present invention has disclosed a sliding-vane air compressor with rolling in oil free lubrication, which includes main air cylinder and rotor as the rotor to be set in the air cylinder ecentrically. There will be rotor slots opened on the rotor to hold the sliding-vane which can slide freely along radical direction in each of the rotor slots and the sliding-vane will be made of light weight alloy material of aluminium alloy instead of self-lubrication material of graphite as the top end and bottom part of the sliding vane as well as both sides of the said rotor slots will be erected with bearing seats which sets rolling bearings on them. The high temperature resistant lubricant will be packed in inside of the bearings with seal ring attached for sealing and the friction between the sliding-vane and the air cylinder as well as the friction between the rotors are the rolling friction.

Description

Technical field: [0001] The invention relates to an air compressor, in particular to an oil-free sliding vane air compressor. Background technique: [0002] Oil-free sliding vane air compressors are discussed in the general mechanical part of the Mechanical Engineering Handbook and other works on positive displacement compressors. The sliding vanes of oil-free sliding vane air compressors use graphite and other self-lubricating materials. The rotor slides in the groove and rotates with the rotor, and the top of the sliding plate slides and rubs against the inner surface of the cylinder during operation. Due to the high brittleness of graphite and other self-lubricating materials, low strength, and easy breakage, the sliding friction between the sliding vane and the cylinder, the sliding vane and the rotor groove will generate a lot of heat and make the sliding vane wear seriously, further increasing the possibility of damage . Invention content: [0003] In view of the s...
