Specific embodiment
The structural representation of a kind of diaphragm coupling with protective cover that Fig. 1 is provided for the utility model, such as Fig. 1 institutes
Show, the diaphragm coupling that the present embodiment has protective cover includes：Diaphragm coupling 11 and protective cover 12.Protective cover 12 is barrel-shaped knot
Structure, the bottom of protective cover 12 is provided with a centre bore 121 and multiple connecting holes 122, and connecting hole 122 is centrally located hole 121
Around；Diaphragm coupling 11 is arranged in protective cover 12, and the axle 111 of diaphragm coupling 11 is located in centre bore 121, diaphragm connection
The bolt of axle device 11 passes through multiple connecting holes 122 and fixes.
Specifically, diaphragm coupling 11 is alternately connected by several groups of bolts of diaphragm 113 with two axle sleeves 112.This implementation
Example by taking the single-iris shaft couplings of one group of diaphragm and two axle sleeves composition as an example, but be not limited to single-iris shaft coupling, or by
A stiffener and two double diaphragm couplings of axle sleeve composition in the middle of two groups of diaphragms, two groups of diaphragms, can also be middle
Three diaphragm couplings being made up of two stiffeners and two axle sleeves in the middle of three groups of diaphragms, three groups of diaphragms.Diaphragm coupling
11 two structures of axle sleeve 112 are identical, and two bolt quantities of axle sleeve 112 of connection are determined by equally distributed hole count on axle sleeve 112
It is fixed, 6 bolts are used in the present embodiment, but be not limited to 6 bolts, it would however also be possible to employ 2,4,8 bolts etc..Bolt is to use
Carry out transmitting torque, using connected mode staggeredly be in order to prevent bolt to be unlikely in transmitting torque and meanwhile release, throw away,
Failure.
In actual applications, the diameter of centre bore 121 is greater than the external diameter of the axle 111 of diaphragm coupling 11, specifically, in
The diameter of heart hole 121 can be more than the external diameter 0.1-0.2mm of the axle 111 of diaphragm coupling 11.Centre bore 121 is located at the bottom of protective cover 12
Portion center, the diaphragm of diaphragm coupling 11 is caused for the axle 111 of diaphragm coupling 11 to be located in centre bore 121
113 in protective cover 12, therefore it is required that the external diameter of the axle 111 with diameter greater than diaphragm coupling 11 of centre bore 121.When bolt is disconnected
After splitting, to make will not still to be flown out immediately in the axle sleeve 112 of the one end of close protective cover 12 of operating, centre bore 121 and diaphragm shaft coupling
Gap between the axle 111 of device 11 can not be too big, for example, axle 111 of the diameter of centre bore 121 than diaphragm coupling 11 can be set
The big 0.1-0.2mm of external diameter so that the axle 111 of diaphragm coupling 1111 can successfully pierce into centre bore 121, while in turn ensure that
After bolt fracture, the axle sleeve 112 still in one end of close protective cover 12 of operating will not fly out immediately.
In the present embodiment, the quantity of connecting hole 122 and the quantity of the bolt of diaphragm coupling 11 can with it is identical can not also
It is identical, it is without limitation.Connecting hole 122 is located at the bottom of protective cover 12, is evenly distributed in around centre bore 121, and bolt is worn
Cross connecting hole 122 and fix diaphragm coupling 11 and protective cover 12.Because bolt will not only connect diaphragm coupling 11, also by film
Piece shaft coupling 11 is fixedly connected with protective cover 12, accordingly, it would be desirable to from bolt more long.Preferably, the quantity of connecting hole 122 with
The quantity of the bolt of diaphragm coupling 11 is identical, for example, in example shown in Fig. 1, diaphragm coupling 11 is connected using 6 bolts
Connect, then the quantity of connecting hole 122 is also 6, protective cover 12 is firmly connected with diaphragm coupling, and more permanent plays diaphragm
The effect of piece shaft coupling 11.It is connected by screw bolts in the present embodiment, not only makes protective cover convenient disassembly, in also makes diaphragm coupling
The convenient disassembly of diaphragm, changes simple.
In this practical application, the internal diameter of protective cover 12 is greater than the external diameter of the axle sleeve 112 of diaphragm coupling 11, specifically,
The internal diameter of protective cover 12 can be more than the external diameter 0.1-0.2mm of the axle sleeve 112 of diaphragm coupling 11.It is former after diaphragm 113 is broken
Originally the diaphragm coupling 11 in gap occurs in that rotary gap without spin, if even if operating personnel have been broken without discovery diaphragm 113,
Remaining in operation can trigger bolt fracture so that two axle sleeves 112 of diaphragm coupling 11 are separated, now away from centre bore 121 1
The axle sleeve at end flies out at first.For make still operating the axle sleeve away from the one end of centre bore 121 will not fly out immediately, protective cover 12 with
Gap between diaphragm coupling 11 can not be too big, therefore can set the axle sleeve of the internal diameter than diaphragm coupling 11 of protective cover 12
The big 0.1-0.2mm of 112 external diameters so that diaphragm coupling 11 can be successfully positioned in protective cover 12, while in turn ensure that bolt
After fracture, the axle sleeve away from the end of protective cover 12 still in operating will not fly out immediately.
Further, multiple peep holes 123 are provided with the side wall of protective cover 12.Optionally, on the side wall of protective cover 12
Multiple peep holes 123 be evenly distributed.Peep hole 123 is easy to whether observation diaphragm coupling 11 is broken.Diaphragm coupling 11
It is noiseless under normal operation, when occurring abnormal sound in operation process, it may be possible to which the diaphragm 113 of diaphragm coupling 11 goes out
Now it is broken, needs to stop the operation of diaphragm coupling 11 in the prior art, dismantle protective cover 12, checks whether abnormal sound is due to film
What the fracture of piece 113 caused.And by opening up peep hole 123 on the side wall of protective cover 12 in the present embodiment, without stopper film
Just whether observable diaphragm 113 is broken for the operation of piece shaft coupling 11, realize fast and safely judge abnormal sound it is abnormal whether due to
Diaphragm 113 is broken and causes.
4 peep holes are provided with example shown in Fig. 1 on protective cover 12, but are not limited to 4, the quantity of peep hole 123
Can be the multiples such as 1,2,3, operating personnel can set the quantity of peep hole 123 according to practical application.In order to more easily right
Whole diaphragm 113 is observed, and is set multiple peep holes 123 and is evenly distributed on the side wall of protective cover 12, is realized equidistant
The whole diaphragm 113 of observation.Meanwhile, peep hole 123 is located at the intermediate altitude of the side wall of protective cover 12 so that peep hole 123 is just right
Diaphragm 113, realizes whether best observation diaphragm 113 is broken.
Optionally, protective cover 12 is formed using steel material turning, to ensure the position essence of each machined surface of protective cover 12
Degree.
The diaphragm coupling with protective cover that the present embodiment is provided, by setting a protection outside diaphragm coupling
Cover, by the axle of diaphragm coupling through the centre bore of protective cover bottom, multiple connecting holes of protective cover bottom is passed through using bolt,
The fixation of diaphragm coupling and protective cover is completed, diaphragm coupling is formed by protective cover is protected, it is to avoid due to diaphragm connection
Personal and the equipment safety accident, and protective cover that the fracture of axle device triggers are bolted with diaphragm coupling, convenient dismounting
Change.
Finally it should be noted that：Various embodiments above is only used to illustrate the technical solution of the utility model, rather than it is limited
System；Although being described in detail to the utility model with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
