Description

Impeller fixing mechanism

Technical Field

The utility model belongs to the technical field of the impeller, concretely relates to impeller fixed establishment.

Background

The impeller is used as a component of a motor, and usually the impeller moves relative to a main shaft in a high-speed operation state, and when a large number of fixing structure components are used, a fault often occurs due to high-speed operation, so that a fixing mechanism which has a simple structure and can effectively prevent the impeller from rotating relative to the main shaft is needed to be developed.

Disclosure of Invention

In order to overcome the shortcomings and deficiencies in the prior art, the utility model aims to provide an impeller fixing mechanism which can effectively prevent the impeller from rotating relative to the main shaft after the impeller rotates at a high speed.

The purpose of the utility model is realized through the following technical scheme: the utility model provides an impeller fixing mechanism, includes main shaft, impeller and is used for being fixed in the mounting of main shaft with the impeller, the impeller includes the body, sets up in the connecting portion at body middle part and fixed a plurality of blades that set up in the body, and is a plurality of blade evenly distributed in on the body, the mounting passes through connecting portion with main shaft fixed connection.

Furthermore, the fixing piece is a screw, the connecting portion is three first screw holes which are externally tangent to each other, the circle centers of the cross sections of the three first screw holes are distributed on the top point of an equilateral triangle, three second screw holes are formed in the output end of the main shaft and correspond to the three first screw holes, and the screw penetrates through the first screw holes and the second screw holes to be in threaded connection with the main shaft.

Further, the mounting includes screw, lock washer and pin, connecting portion including set up in the third screw at impeller middle part and set up a plurality of through-holes around the third screw of impeller, the screw pass through the third screw with main shaft fixed connection, the pin run through in the through-hole with the main shaft firmware is connected, the lock washer is located between the nut and the impeller of screw.

The beneficial effects of the utility model reside in that: the utility model discloses a set up connecting portion in the middle part of the impeller, use the mounting to be fixed in the mode of main shaft with the impeller for whole impeller fixed establishment simple structure, and can effectively prevent that the relative main shaft of impeller from rotating, also easily processing production.

Detailed Description

In order to facilitate the understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

Referring to fig. 1-4, an impeller fixing mechanism includes a main shaft 1, an impeller 2, and a fixing member for fixing the impeller 2 to the main shaft 1, where the impeller 2 includes a main body 21, a connecting portion disposed in the middle of the main body 21, and a plurality of blades 22 fixedly disposed on the main body 21, the plurality of blades 22 are uniformly distributed on the main body 21, and the fixing member is fixedly connected to the main shaft 1 through the connecting portion.

The utility model discloses a set up connecting portion at 2 middle parts of impeller, use the mounting to be fixed in impeller 2 in the mode of main shaft 1 for 2 fixed establishment simple structure of whole impeller, and can effectively prevent 2 relative main shafts of impeller 1 and rotate, also easily processing production.

Furthermore, the fixing piece is a screw 3, the connecting portion is three first screw holes 4 which are externally tangent to each other, the circle centers of the cross sections of the three first screw holes 4 are distributed on the top point of an equilateral triangle, three second screw holes are formed in the output end of the main shaft 1, the three second screw holes correspond to the three first screw holes 4, and the screw 3 penetrates through the first screw holes 4 and the second screw holes to be in threaded connection with the main shaft 1.

The utility model discloses a set up three tangent first screw 4 and be connected with screw 3, can be stable be fixed in main shaft 1 with impeller 2 on, fixed impeller 2's axial and radial effectively avoid impeller 2 and main shaft 1 to take place relative rotation.

Further, the mounting includes screw 5, lock washer 6 and pin 7, connecting portion including set up in the third screw 8 at 2 middle parts of impeller and set up a plurality of through-holes 9 around 2 third screws 8 of impeller, screw 5 through third screw 8 with 1 fixed connection of main shaft, pin 7 run through in through-hole 9 with 1 firmware of main shaft is connected, lock washer 6 is located between the nut of screw 5 and the impeller 2.

In the embodiment, the impeller 2 is fixed on the main shaft 1 by the screw 5, the stop washer 6 and the pin 7, so that the impeller 2 and the main shaft 1 are effectively prevented from rotating relatively.

The above-mentioned embodiment is the utility model discloses the implementation of preferred, in addition, the utility model discloses can also realize by other modes, not deviating from the utility model discloses any obvious replacement is all within the protection scope under the prerequisite of design.
