Abstract

The utility model provides an improved cylinder-typed air compressor, which is characterized in that a rotor is composed of a central shaft, a shaft rolling frame, a cylinder shaft, and a cylinder. When the rotor rotates, the rotor and the cylinder which is matched with the inner surface of the air cylinder rotate along with the central shaft and do the rotation around the cylinder shaft to form well rolling contact. A rolling column is arranged at the contact end point of a sliding plate and the cylinder to cause the sliding plate and the cylinder to form good rolling contact during the contact movement. Because of the improvement of the moving contact of the main moving parts, the abrasion of the related parts of the air compressor and the heating value during the friction are reduced.

Description

Cylinder-type air compressor

The utility model relates to a kind of eccentric rolling rotor type compressor, particularly a kind of eccentric rolling rotor-type roller type air compressor.

Existing eccentric rolling rotor type compressor, product as Switzerland Ai Xie-Wei Si (Escher-Wyss) company, its structural representation such as Fig. 3, establish eccentric rotor 2 ' in the cylinder 1 ', when rotor when cylinder axis O rotates, rotor is close on the cylinder 1 ' internal surface and rolls, constitute a crescent shape space between rotor 2 ' outer surface and the cylinder 1 ' internal surface, its position changes with the corner of rotor 2 ', slide plate 4 ' is separated into two-part with crescent-shaped space, a part and suction port 6 ' communicate, another part communicates with relief opening 3 ', slide plate 4 ' relies on spring 5 ' to be pressed on the rotor 2 ' outer surface, and rotor 2 ' rotated for two weeks around cylinder axis O ', can finish air-breathing, compression, exhaust process.There is following point in this structure:

1. rotor 2 ' is close on the cylinder 1 ' internal surface and rolls, though usually 0.1～0.2mm gap is arranged, surface both is still in more serious friction, increase the abrasion of parts on the one hand, then can produce bigger heat on the other hand, thereby need perfect cooling method, make equipment complicated;

2. slide plate 4 relies on springs 5 ' to be pressed on rotor 2 ' outer surface, also has the friction in the movement process, occurs the abrasion of parts equally and produces defective such as heat.

The purpose of this utility model is that a kind of improved roller type air compressor will be provided, and with simpler structure, makes the moving link of compressor reduce abrasion and heating.

The utility model is achieved in that the roller type air compressor is made up of cylinder, rotor, relief opening, slide plate, spring and suction port, its structural feature is that rotor is made up of central shaft, rotor commentaries on classics frame, drum shaft and cylinder, drum shaft is bearing in rotor to be changeed on the bearing of frame, cylinder is assemblied in drum shaft, rotor changes frame and the central shaft mount is integral, when rotor rotates, the cylinder that cooperates with cylinder surfaces, except around central shaft rotates, still can rotate around drum shaft, thereby form good rolling contact; The contact jaw place of slide plate and cylinder establishes a roller, and roller is installed on the roller axle, and roller axle is supported on two bearings of the plate body end of slide plate, and in the contact movement process of slide plate and cylinder, cylinder forms good rolling with roller and contacts.

The utility model can improve the contact surface friction of rotor and cylinder because rotor adopts rolling type structure; Slide plate adopts roller construction, improves the friction of slide plate and rotor contact surface, and both all can reach the good result that reduces the moving link abrasion and reduce friction heating, and can exempt complicated cooling equipment, simplify compressor arrangement.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1, be according to the roller type air compressor sectional elevation that the utility model proposes.

Fig. 2, be the longitudinal section of Fig. 1 structure.

Fig. 3, be that the axle of Fig. 1 structure is surveyed view.

Fig. 4, be traditional eccentric rolling rotor type compressor schematic representation.

With reference to Fig. 1,2,3, the roller type air compressor is made up of cylinder 1, rotor 2, relief opening 3, slide plate 4, spring 5 and suction port 6.Cylinder 1 is established sealing 101 with slide plate 4 cooperation places; Rotor 2 changes frame 202, drum shaft 203 and cylinder 204 by central shaft 201, rotor and forms, central shaft 201 is bearing on the bearing of installing on cylinder 1 housing 102, rotor changes frame 202 and is integral with central shaft 201 mounts, drum shaft 203 is bearing in rotor to be changeed on the bearing 205 of frame 202, by cylinder 204 and drum shaft 203 assemblings that soft elastic material is made, the material of making cylinder 204 has ebonite, engineering plastics etc.; Relief opening 3 is fixed into one with cylinder 1 housing, establishes an outlet valve 301 in the cylinder 1 and the joint of relief opening 3; Slide plate 4 is made up of plate body 401 and roller 402, a roller 402 is established in plate body 401 ends of slide plate 4 and the contacting point of cylinder 204, roller 402 is installed on the roller axle 403, roller axle 403 is supported on two bearings 404 of plate body 401 ends of slide plate 4,402 of plate body 401 and rollers are established soft sealing strip, when compressor cooperates vertical axis prime mover to use, the bottom of the plate body 401 of slide plate 4 is bearing on one group of roller 407, slide plate 4 to-and-fro motion are by each one group of roller, 405 guiding of plate body 401 bi-side, and roller 405 is located on the framework 406 that sets firmly on the cylinder 1; Spring 5 one ends are held in the end of plate body 401, and the other end of spring 5 is fixed on framework 406 through bolt 501; Suction port 6 is fixed into one with cylinder 1 housing, establishes an air inlet filter 601 in the ingress of suction port 6.

When prime mover drives rotor 2 by central shaft 201, the cylinder 204 that cooperates with cylinder 1 internal surface, except around central shaft 201 rotations, still can contact thereby form good rolling around drum shaft 203 rotations, reduce the abrasion and the heating of surface of contact, during rotor 2 rotations, promote slide plate 4 by roller 402 and overcome the motion of spring 5 active forces, cylinder 204 forms good rolling with roller 402 and contacts, and reduces the abrasion and the heating of surface of contact.The roller type air compressor is except being applicable to general prime mover driven, and especially suitable and band concentrator fluid can the supporting use of conversion equipment.
