Description
[technical field]
The utility model is related to shaft coupling, specifically a kind of bellows coupling for surveying damage.
[background technology]
Shaft coupling is mainly used for the connection in machine driving, is the critical piece in machine driving.It is connection master that it, which is acted on,
Moving axis and driven shaft to transmit movement and torque, and are compensated due to the deformation after foozle, installation error, carrying and temperature
Axial direction caused by variation of degree etc. radially and angularly deviates.Existing bellows coupling high speed rotation, when transmitting torque, gold
Belong to end and easily generate skidding with bellows, bellows easily bursts, and service life is short.And during bellows use, it is difficult to
Judge whether the air-tightness of bellows is intact, checking process is again very cumbersome.
[utility model content]
The purpose of this utility model seeks to solve above-mentioned deficiency and provide a kind of bellows coupling for surveying damage,
The air-tightness of bellows can not only be detected, conducive to judging whether bellows coupling damages, the good work of bellows can be kept
Make efficiency, and life of product is long, assembling repair is also more convenient.
A kind of bellows coupling for surveying damage is designed to achieve the above object, including metal bellows 1, shaft coupling with holes
Device 3 and bellows coupling 4, the both ends of the metal bellows 1 are equipped with flat segments, the metal bellows 1, shaft coupling with holes
Be tightly connected between device 3, bellows coupling 4, the internal cavity 8 for forming closed structure, the metal bellows 1 with it is with holes
Shaft coupling 3, bellows coupling 4 junction be respectively equipped with groove, sealing ring 6, the wavy metal are equipped in the groove
1 both ends of pipe are fixedly connected with shaft coupling 3 with holes, bellows coupling 4 by set screw 7 respectively, are opened on the shaft coupling 3 with holes
There is air-filled pore, charge valve 5 is installed at the air-filled pore, the charge valve 5 is tightly connected metal bellows 1.
Clamping screw 2 is equipped on the shaft coupling with holes 3, bellows coupling 4.
The utility model compared with the existing technology, structure novel, simple, reasonable design, by by wavy metal tube body
Both ends are fixed by screw so that metal bellows and bellows coupling link into an integrated entity, and charge valve is linked into advance
It holds successfully on the shaft coupling with holes in hole, the gas of test is filled with by charge valve, and fixed with clamping screw at shaft coupling both ends
To test equipment, so as to facilitate installation of the bellows in test；Since bellows is thin metallic tubd, when bellows goes out
When now rupturing, charger shows pressure anomaly and alarms, so as to detect whether bellows has damage, conducive to bellows connection is judged
Whether axis device damages, while makes life of product long, and assembling repair is also more convenient.

[specific embodiment]
The utility model is made below in conjunction with the accompanying drawings further explained below：
As shown in attached drawing 1 and attached drawing 2, the utility model includes metal bellows 1, shaft coupling with holes 3 and bellows shaft coupling
Device 4 is formed, and the left and right ends of the metal bellows 1 are equipped with flat segments, and the end of flat segments is fixed by set screw 7 to be connected
Tape splicing hole shaft coupling 3, bellows coupling 4.Metal bellows 1, shaft coupling with holes 3 form close with 4 inside of bellows coupling
Close the cavity 8 of structure.Charge valve 5 is installed, charge valve 5 is connected to connection by the hole accomplished fluently on shaft coupling on shaft coupling 3 with holes
On axis device.There is clamping screw 2 respectively on shaft coupling 3 with holes, bellows coupling 4, shaft coupling is connected to test device
On, and be fixed.
As shown in attached drawing 3,4, there are clamping screw 2 and set screw 7 on bellows coupling 4 and shaft coupling 3 with holes, pass through
Clamping screw 2 and set screw 7 then may be such that the installation of metal bellows is more accurate；It can also be surveyed in the metal bellows
More stablize during examination.It is connected and sealed between metal bellows 1 and shaft coupling by sealing ring 6 simultaneously, so as to further
Prevent metal bellows from causing fatigue damage to occur, and cause the leakage of bellows due to being used for a long time, so as to cause test
Result it is inaccurate.That is, the increase of the sealing ring 6 then improves the accuracy of bellows test.
The utility model is simultaneously not limited to the embodiments described above, and other any spirit without departing from the utility model are real
Matter with made under principle change, modification, replacement, combine, simplification, should be equivalent substitute mode, be included in this practicality
Within novel protection domain.
