Description
Technical field
The present invention relates to pulling force connector technical field more particularly to a kind of tension bearings and its device.
Background technique
In tension system, because of field condition complicated and changeable, the radial torque being inevitably generated between pulling force both sides.
Such as during crane slings weight, weight is because wind area is different, and there have been (drawn with direction of pull in tension system
Rope) be shaft radial torque, weight occur radial rotating.
Excessive radial torque can make pulling force carrier kink phenomenon occur, to cause pulling force distortion, tension ohject displacement
The problems such as increase, the damage of pulling force carrier structure.Wherein, pulling force carrier is the object for conducting pulling force；Such as rope, line, stick etc..Pulling force
The axial direction of carrier refers to the rotation center axis direction of pulling force carrier, generally Chong Die with direction of pull.Pulling force carrier radial and normal to
It is axial.The radial rotary of pulling force carrier refers to the rotation using axial direction as rotary shaft.Kink phenomenon refer to using direction of pull as shaft,
When pulling force carrier both ends are along different directions radial rotary, pulling force carrier the phenomenon that deformation occurs due to torque.The kink of pulling force carrier
Afterwards, the distortion of pulling force can occur for pulling force, and distortion degree is more serious with kink degree and the increase of the order of kink.
Currently, it is well known eliminate pulling force carrier between excessive radial torque method be in the way of clearance fit, such as
Universal buckle.Fig. 1 is the structural schematic diagram of existing universal buckle, and arrow direction is direction of pull in figure；In Fig. 1, the first pull ring 1,
First limiting card 2 and the second limiting card 3 are integrated, and the second pull ring 4 and third limiting card 5 are integrated；The setting of third limiting card 5 exists
Between first limiting card 2 and the second limiting card 3, and the first limiting card 2 and the second limiting card 3 respectively with 5 gap of third limiting card
Cooperation.First pull ring 1 and the second pull ring 4 can carry out radial rotating by axis of direction of pull while transmitting pulling force.Cause
This, when the first 1 radial rotating of pull ring, the second pull ring 4 will not radial rotating.Similarly, when the second 4 radial rotating of pull ring, first is drawn
Ring 1 will not radial rotating.First pull ring 1 and the second pull ring 4 are two pulling force carriers, and universal buckle eliminates two drawings in the above described manner
Excessive torque between power carrier.
Premise in the method for excessive radial torque between clearance fit elimination pulling force carrier is the gap of two pulling force carriers
Cooperation allows for sliding.Its problem of, is:
One, the rotation threshold value for driving clearance fit to radially slide is big.That is, it needs to which torque is more than the static friction of clearance fit
Power can just play the role of excessive radial torque between elimination pulling force carrier；
Two, in actual use, the clearance fit of pulling force carrier is chronically at sliding friction state, and contact surface is because of friction
It is damaged and becomes coarse, increase frictional force more, to cause clearance fit obstruction or stuck；
After the clearance fit of pulling force carrier blocks or is stuck, radial torque cannot be eliminated.It is existing that pulling force carrier will appear kink
As and there is pulling force distortion, cause tension ohject displacement distance increase, pulling force carrier structure damage the problems such as.
Therefore, the application provides a kind of new tension bearing and its device regarding to the issue above, can reduce pulling force load
Rotation threshold value between body reduces the probability for kink phenomenon occur.
