Embodiment 1

[0029] Arc surface universal diaphragm coupling, such as figure 1 and figure 2 As shown, it includes the driving flange 1, the driven flange 2, the diaphragm group 3 located between the driving flange 1 and the driven flange 2, and the diaphragm group 3, the driving flange 1 and the driven flange 2 and an expansion joint assembly 4 that is fixed as one; the diaphragm group 3 is connected as a whole through the diaphragm group arc surface movable sleeve assembly, and the expansion joint assembly 4 runs through the diaphragm group arc surface movable sleeve assembly Connect with driving flange 1 and driven flange 2.

[0030] The cambered movable sleeve assembly of the diaphragm group is composed of a cambered sleeve 5 penetrating through the diaphragm set 3 , and a cambered collar 6 arranged in the cambered sleeve 5 and connected with the expansion joint assembly 4 .

[0031] In the present invention, the function of the expansion joint assembly 4 is to transition fit with th...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that in order to achieve a better stable installation effect, such as figure 2 As shown, the movable sleeve component of the diaphragm group arc is also provided with a rivet ring 7 and an arc pad 8, and the specific setting method is as follows:

[0037] One side of the cambered movable sleeve assembly of the diaphragm group is provided with a riveting ring 7 that cooperates with the cambered sleeve 5 to compress the diaphragm group 3; through the cooperation of the riveting ring, multiple sheets of the same thickness can be effectively The film sheet is pressed and welded as a whole. The other side of the movable sleeve assembly with arcuate surface of the diaphragm set is provided with an arcuate surface pad 8 .

Embodiment 3

[0039] The difference between this embodiment and embodiment 1 or embodiment 2 is that, as figure 2 and Figure 4 As shown, the structure of the expansion joint assembly 4 in this embodiment is different, and the specific structure of the expansion joint assembly 4 in this embodiment is as follows:

[0040] The expansion joint assembly 4 consists of an expansion sleeve 41 with a tapered hole inside, a tapered sleeve 42 arranged in the expansion sleeve 41 and matched with the taper of the tapered hole, and a tension bolt 44 installed at the smaller end of the tapered sleeve 42 composition.

[0041] The installation steps of the expansion joint assembly 4 in the present embodiment are as follows:

[0042] After the flange and the diaphragm group are assembled, install the expansion sleeve from the reamed hole of the flange into the clearance fit, and then put the smaller end of the taper sleeve into the expansion sleeve to realize the gap between the expansion sleeve and the ...

Abstract

The invention discloses an arcuate universal diaphragm shaft coupling, which mainly solves the problem of short service life caused by the rigid connection between the flange and the diaphragm group in the prior art. The invention includes a driving flange (1), a driven flange (2), a diaphragm group (3) located between the driving flange (1) and the driven flange (2), and a penetrating driving flange (1 ), the diaphragm group (3) and the driven flange (2) and the expansion joint assembly (4) which is fixed as one; it is characterized in that: the diaphragm group (3) can be moved through the arc surface of the diaphragm group The sleeve assembly is connected as a whole, and the expansion joint assembly (4) penetrates through the arc surface of the diaphragm set to move the sleeve assembly to connect with the driving flange (1) and the driven flange (2). The invention has the advantages of flexible connection, universal swing within a certain range, effective compensation of installation or operation deviation and long service life.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to an arc surface universal diaphragm shaft coupling. Background technique [0002] At present, the diaphragm coupling on the market is composed of a driving flange, a driven flange, a diaphragm group, and a hinged bolt group, in which the diaphragm group is composed of a plurality of films with the same thickness riveted together by ordinary rivets. , The inner hole of the rivet sleeve is a hinged hole. The hinged bolts and the hinged holes are transitionally matched to connect the diaphragm group with the main and driven flanges respectively, so as to realize power transmission. However, due to the transitional fit between the hinged bolt and the hinged hole, it is a rigid connection. When there is any angular, radial, or axial deviation in the installation or operation of the unit, the deviation compensation must be realized through the deformation of the diaphragm set. The diaphragm group w...
