Abstract
The utility model relates to a part of a forward multi-winged centrifugal impeller. A central disk component of the forward multi-winged centrifugal impeller comprises a round central disk and a shaft sleeve which are in rivet connection. A plurality of torn openings which are used for installing blades are regularly arranged at the outer periphery of the round central disk; a shaft sleeve riveting hole is arranged at the circle center of the round central disk; the shaft sleeve riveting hole comprises a round hole and three reinforcing notches which are communicated with the round hole; the diameter of the round hole is matched with the outer diameter of the shaft sleeve; three reinforcing notches are regularly arranged along the circle center of the round hole. The central disk component of the forward multi-winged centrifugal impeller has the advantages of novel structure of the central disk, no slipping of the shaft sleeve and the central disk and large rotational torque of the central disk and the shaft sleeve.
Description
Technical field
The utility model relates to the accessory on a kind of forward multiple wing centrifugal impeller.
Background technique
The forward multiple wing centrifugal impeller mainly comprises two Qian Quan, many arc shaped blades and mid-game assembly; The blade two ends are enclosed before being fixedly connected two respectively; The mid-game assembly is made up of mid-game and axle sleeve riveted joint, and the outer ledge of mid-game is provided with tearing notch, and the middle part of blade is fitted on the tearing notch of mid-game.Electric machine main shaft drives the forward multiple wing centrifugal wheel rotation through axle sleeve; Axle sleeve riveted holes in the existing mid-game is a circular port; After mid-game was riveted through round sleeve riveted holes and axle sleeve, the driving torque of mid-game and axle sleeve was less, is generally below the 60N.m; The situation that forward multiple wing centrifugal impeller axle sleeve and mid-game meeting when running up are skidded, thus impeller damaged.In addition; The tearing notch cross section of the mid-game in the existing mid-game assembly is vertical bar shaped, and the cross section of blade is curved, and blade is riveted on the blade twist and warping distortion that can cause riveted joint place on the vertical bar shaped tearing notch of mid-game; Meeting attenuation of part position even fracture cause the riveting intensity of blade to reduce.
Summary of the invention
The purpose of the utility model is the defective that exists for the mid-game assembly that solves on the existing forward multiple wing centrifugal impeller; A kind of mid-game novel structure is provided; Axle sleeve and mid-game can not skidded, the mid-game assembly on the big forward multiple wing centrifugal impeller of the driving torque of mid-game and axle sleeve.
In order to realize above-mentioned purpose, the technological scheme below the utility model has adopted:
Mid-game assembly on the forward multiple wing centrifugal impeller is made up of circular mid-game and axle sleeve riveted joint, and the outer ledge rule of circular mid-game is provided with a plurality of tearing notches that are used for mounting blades, and the circle centre position of circular mid-game is provided with the axle sleeve riveted holes; Described axle sleeve riveted holes is reinforced breach by circular port and be communicated with it 3 and is constituted, the diameter of circular port and the external diameter of axle sleeve coupling, and 3 reinforcing gap positions are regularly arranged along the center of circle of circular port.
As preferably, it is curved that the outer ledge of said circular mid-game is used for the tearing notch cross section of mounting blades, and blade is fitted in arc tearing notch upper blade can deformed damaged, can improve the riveting intensity of blade and mid-game.
Adopted the mid-game assembly on the forward multiple wing centrifugal impeller of technique scheme; The axle sleeve riveted holes is reinforced breach by circular port and be communicated with it 3 and is constituted; The diameter of circular port and the external diameter of axle sleeve coupling, 3 reinforcing gap positions are regularly arranged along the center of circle of circular port, after axle sleeve is riveted on the axle sleeve riveted holes; A part of material of axle sleeve is pressed against 3 and reinforces in the breach; Thereby make more firm being connected of axle sleeve and mid-game, increased the driving torque of mid-game and axle sleeve, increased the intensity and the running speed of forward multiple wing centrifugal impeller.The advantage of the mid-game assembly on this forward multiple wing centrifugal impeller is the novel structure of mid-game, and axle sleeve and mid-game can not skidded, and the driving torque of mid-game and axle sleeve is big.

Fig. 3: the enlarged diagram at A place among Fig. 1.
Embodiment
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3 the embodiment of the utility model is done a detailed explanation.
Like the mid-game assembly on Fig. 1, Fig. 2 and the forward multiple wing centrifugal impeller shown in Figure 3; 2 riveted joints constitute with axle sleeve by circular mid-game 1; The outer ledge rule of circular mid-game 1 is provided with a plurality of tearing notches 4 that are used for mounting blades, and the circle centre position of circular mid-game 1 is provided with axle sleeve riveted holes 3.Axle sleeve riveted holes 3 is reinforced breach 32 by circular port 31 and be communicated with it 3 and is constituted; The external diameter coupling of the diameter of circular port 31 and axle sleeve 2; 3 reinforcing gap positions are regularly arranged along the center of circle of circular port 31, and promptly adjacent arbitrarily two angles of reinforcing between the breach 32 are 120 degree.After axle sleeve 2 is riveted on the axle sleeve riveted holes 3; A part of material of axle sleeve 2 is pressed against 3 and reinforces in the breach 32, thereby makes axle sleeve 2 and mid-game 1 more firm being connected, and has increased the driving torque of mid-game 1 with axle sleeve 2; And increase by 50% at least, promptly driving torque reaches more than the 90N.m.
It is curved that the outer ledge of circular mid-game 1 is used for tearing notch 4 cross sections of mounting blades, and blade is fitted in arc tearing notch 4 upper blades can deformed damaged, can improve the riveting intensity of blade and mid-game 1.
Claims (2)
1. the mid-game assembly on the forward multiple wing centrifugal impeller is made up of circular mid-game and axle sleeve riveted joint, and the outer ledge rule of circular mid-game is provided with a plurality of tearing notches that are used for mounting blades, and the circle centre position of circular mid-game is provided with the axle sleeve riveted holes; It is characterized in that described axle sleeve riveted holes reinforces breach by circular port and be communicated with it 3 and constitute, the diameter of circular port and the external diameter of axle sleeve coupling, 3 reinforcing gap positions are regularly arranged along the center of circle of circular port.
2. it is curved that the mid-game assembly on the forward multiple wing centrifugal impeller according to claim 1, the outer ledge that it is characterized in that said circular mid-game are used for the tearing notch cross section of mounting blades.
