Embodiment 1

[0054] like figure 1 , image 3 and Figure 5 As shown, a power conversion device for an air compressor or a vane engine in this embodiment includes a casing 2, a rotor body 11 and a vane body 10, the casing 2 is fixedly arranged, and a cylindrical container is opened in the casing 2 The cavity, preferably, the casing 2 is a tubular structure, the rotor body 11 is a cylindrical structure, the rotor body 11 is rotatably arranged in the accommodating cavity, the axis of the rotor body 11 and the axis of the accommodating cavity are eccentrically arranged, and the rotor body 11 is provided with There are a plurality of blade grooves 107, and each blade groove 107 is slidably connected with a blade body 10. When the rotor body 11 rotates, under the action of centrifugal force, one end of each blade body 10 protruding from the rotor body 11 abuts against the casing 2. On the inner wall surface 21 of the casing, the casing 2 is provided with a first ventilation hole 1 and a second...

Embodiment 2

[0057] like figure 1 , Figure 5 , Figure 8 and Figure 10 As shown, a power conversion device for an air compressor or a vane engine in this embodiment includes all the technical features in Embodiment 1, except that the number of vane grooves 107 is an even number, for example, in a preferred In this embodiment, there are six blade grooves 107, and the included angle between the center surfaces of every two adjacent blade grooves 107 is 60°. When there are n blade grooves 107, the center surface of the adjacent blade grooves 107 The included angle between them is 360° divided by n, and each two vane slots 107 are arranged in pairs, and the two vane slots 107 arranged in pairs are located in the same plane passing through the axis of the rotor body 11. The two vane slots 107 arranged in pairs A blade connecting rod 12 is provided inside; such as Figure 5 and Figure 11 As shown, it also includes a first bushing 103 , a second bushing 104 and a third bushing 121 , and e...

Embodiment 3

[0060] like figure 1 and Figure 5 As shown, a power conversion device for an air compressor or a vane engine in this embodiment includes all the technical features in Embodiment 2, and in addition, also includes a first bearing 105, each vane groove 107 Two first bearings 105 are arranged on the end face of the rotor body 11 at the open end of the rotor In the rolling connection, the two first bearings 105 are rotated against the blade body 10. At this time, even if the blade body 10 is contacted with excessive force, a certain interval can be maintained between the rotor body 11 and the blade body 10, so that the blade connecting rod 12 With the function of the first bearing 105, there is no friction between the rotor body 11 and the vane body 10, which solves the problem that may occur with the increase of the weight of the vane when the air compressor or vane engine is made into a large product. The technology of the above large products.

Abstract

The invention discloses a power conversion device for an air compressor or a vane engine. A shell is fixedly arranged, a cylindrical containing cavity is formed in the shell, a rotor body is rotationally arranged in the containing cavity, the axis of the rotor body and the axis of the containing cavity are eccentrically arranged, a plurality of vane grooves are formed in the rotor body, and a vane body is slidably connected into each vane groove; the end, extending out of the rotor body, of each blade body abuts against the inner wall face of the shell, a first vent hole and a second vent hole are formed in the shell, each blade groove extends in the radial direction of the rotor body, a connecting rod groove is formed in the groove bottom of each blade groove, and a blade connecting rod is arranged in each connecting rod groove and slidably arranged in the corresponding blade body in an inserted mode. The problem of abrasion caused by large friction force between a blade body and a rotor body in the prior art is solved. The telescopic blade type power conversion device has the technical effects that the blade body and the rotor of the telescopic blade type power conversion device for the air compressor or the blade engine are not in direct contact, and abrasion between the blade body and the rotor is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of telescopic vane type power conversion devices, in particular to a power conversion device used for an air compressor or a vane engine. Background technique [0002] In the telescopic vane type power conversion device used in air compressors and vane engines, when the eccentric rotor rotates in the casing, the vanes move back and forth in the rotor, and the friction between the vanes and the rotor is large. The larger size of the device structure, the larger the rotor and the blade, the larger the friction force will be. The friction between the blade and the rotor will increase, so it will have a great impact on the efficiency, and it may lead to failure. production impact. [0003] Large-scale products can be produced by reducing the friction between the blades and the rotor. Therefore, the efficiency of large-scale air compressors or vane engines in proportion to their size has b...
