Description
Technical field
The utility model belongs to remote power transmission mechanism, the in particular to transmission shaft of a kind of nuclear power teletransmission mechanism.
Background technique
Valve is one of the important component in nuclear power station, is widely used in the pipeline of each workshop of nuclear power station, therefore
Guarantee valve can fast and accurately be opened and closed to be to be related to the important link of Nuclear Safety.
There is thousands of valve in nuclear power station, the major part in them can carry out local operation, and valve is located at
The extra high region of radioactivity or since too closely etc. objective condition cause to be unable to local operation for operating space, this just needs reality
The opening and closing for applying valve configures dedicated operating mechanism.
In the teletransmission mechanism of the prior art, using being threadedly coupled between Hooks coupling universal coupling and connector sleeve, then pass through taper pin
It fixes, during actual use, teletransmission mechanism needs ceaselessly positive and negative operation, may deposit between taper pin and connector sleeve
It is loosening, and there is abrasion after long-time use, the transmission efficiency decline of this entire teletransmission mechanism resulted in, further,
It is loosened due to existing between taper pin and connector sleeve, the effect of limit is also reduced by, due between connector sleeve and Hooks coupling universal coupling
Using threaded connection, when rotating in one direction always, transmission efficiency will not influence, when ceaselessly positive counter-movement, screw thread
Between gap transmission efficiency will be had an impact, it can be seen that, transmission shaft existing defects in the prior art.
Summary of the invention
In view of the deficiencies of the prior art, the utility model improves the structure of transmission shaft, passes through the locking of setting
Nut locks the position between transmission shaft and the interconnecting piece of Hooks coupling universal coupling, it is avoided to loosen at work, passes
The problem of efficiency of movement reduces, further, the tapered sleeve of setting has the function of preferably ensure that transmission shaft and interconnecting piece to the heart
Concentricity, the stability of transmission is more preferable.
The technical solution of the utility model is as follows:
The transmission shaft of nuclear power teletransmission mechanism comprising two Hooks coupling universal couplings and driving sleeve, it is characterised in that: institute
The both ends for the driving sleeve stated are equipped with connecting hole along axis, and interconnecting piece and the connecting hole of Hooks coupling universal coupling are threaded togather,
Locking nut is additionally provided on the interconnecting piece, locking nut covers on the end face of driving sleeve, further includes grafting transmission shaft
The taper pin of set and interconnecting piece.
The side of the locking nut is equipped with tapered sleeve, and the outer surface of the end of the driving sleeve is equipped with the conical surface, tapered sleeve
With the cone match of driving sleeve end.
The length of the tapered sleeve is greater than the length of the conical surface.
The taper of the conical surface is between 2-3 °.
In conclusion the utility model has the following beneficial effects:
The utility model improves the structure of transmission shaft, by the locking nut of setting to transmission shaft and universal
The problem of position between the interconnecting piece of axis device is locked, it is avoided to loosen at work, and transmission efficiency reduces, into one
Step, the tapered sleeve of setting has the function of preferably ensure that the concentricity of transmission shaft and interconnecting piece, the stability of transmission to the heart
More preferably.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment one；
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1, transmission shaft of the nuclear power with teletransmission mechanism comprising two Hooks coupling universal couplings 302 and driving sleeve
301, the both ends of the driving sleeve 301 are equipped with connecting hole 3010 along axis, but also along the through hole of axis setting, diagram
In be exactly to be designed using the structure of through hole, interconnecting piece 3020 and the connecting hole 3010 of Hooks coupling universal coupling 302 be threaded in
Together, it is additionally provided with locking nut 304 on the interconnecting piece 3020, locking nut 304 is covered in the end face of driving sleeve 301
On, it further include the taper pin 303 of grafting driving sleeve and interconnecting piece.
By the locking nut of setting to the interconnecting piece of Hooks coupling universal coupling and the link position of connecting hole in the utility model
Locked, avoid loosening between driving sleeve and Hooks coupling universal coupling, reduce transmission shaft in positive counter-movement gear it
Between influence of the gap to transmission accuracy, ensure that the transmission efficiency of teletransmission mechanism.
The side of the locking nut 304 is equipped with tapered sleeve 305, and the outer surface of the end of the driving sleeve 301 is equipped with
The conical surface 306 of the conical surface 306, tapered sleeve 305 and 301 end of driving sleeve cooperates, the cooperation of the tapered sleeve and the conical surface of setting, on the one hand,
There is biggish stiction between tapered sleeve and the conical surface, also avoid the problem that locking nut loosens, on the other hand, using tapered sleeve
With the cooperation of the conical surface, has preferably to heart effect, ensure that drive sleeve and interconnecting piece on the same axis.
The length of the tapered sleeve 305 is greater than the length of the conical surface 306, this ensure that the cooperation of tapered sleeve and the conical surface is reliable
Property, both avoid the problem that caused by tapered sleeve length is inadequate cooperation poor reliability.
The taper of the conical surface is between 2-3 °.
In conclusion the utility model has the following beneficial effects:
The utility model improves the structure of transmission shaft, by the locking nut of setting to transmission shaft and universal
The problem of position between the interconnecting piece of axis device is locked, it is avoided to loosen at work, and transmission efficiency reduces, into one
Step, the tapered sleeve of setting has the function of preferably ensure that the concentricity of transmission shaft and interconnecting piece, the stability of transmission to the heart
More preferably, tapered sleeve has the function of also reducing the heart installation difficulty of teletransmission mechanism, and the precision of installation is improved.
