Abstract
The invention discloses a kind of bolt connecting device, which adds two layers of taper guide on the basis of existing bolt fastening structure, and the increase by one of taper guide can bear shearing force, and two anti-can loosen ability axially increased.Guide structure is employed when being bolted, compared to common bolt fastening structure, which can transfer rotation torque.Bolt is avoided to bear to shear.It improves bolted axial direction and resists the ability of loosening so that axially connection is reliable for connected piece.It is at low cost, it is whole non-maintaining.Shear pin, shear connector, end face tooth structure high processing costs, and shearing latch structure dismounting is all more difficult, repair and maintenance is of high cost, which can accomplish whole non-maintaining.
Description
Technical field
The invention discloses a kind of bolt connecting devices, are applicable to the bolted assembling structure of high reliability, especially
It is suitable for be axially reliably connected while transfer the connection structure of rotation torque.The bolt connecting device is using pin bushing-type connection knot
Structure.
Background technology
At present, component connects firmly the various new technologies of assembling with component, new thought continues to bring out, but it is still each to be bolted
The commonly used connection mode of industry, bolt connecting device are directly related to the operation of mechanical system as a kind of assembly method
Safety.Existing bolt connecting device is almost generally using bolt+nut, the attachment device of bolt+threaded hole, some assembling knots
Structure bolt must endure as shearing force or rotation torque so that the structure of design shear pin/shear connector/end-tooth is needed to hold during design
Larger shearing force is born by shearing force or by increasing the diameter of bolt/raising bolt grade, for needing high reliability spiral shell
The reliability of connection must also be improved by increasing bolt quantity by tethering the structure connect, assembly parts quantity be caused to increase, structure is multiple
It is miscellaneous, increase labor intensity, be bolted the security for also reducing assembling to a certain extent, reliability too much.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of bolt connecting device, and the device is in existing spiral shell
On the basis of bolt connecting structure, two layers of taper guide is added, the increase by one of taper guide can bear shearing force, and two can
Anti- to loosen ability axially increased.
It further includes, which employs guide structure when connecting.
It further includes, the guide which carries the conical surface with two is drawn using the axial tension generated in bolt rundown process
Dynamic, while the conical surface generates interference volume, outside diameter generates expansion.
It further includes, after the conical surface tenses in place, bolt is tightened to prescribed torque, in footpath between mating surface inside and outside each connector
To direction generating suitable interference volume, the frictional force being axially formed between the tapered sleeve conical surface prevents connected piece from axially loosening with this,
The reliability of bolt fastening is greatly improved, since the presence of housing, transition tapered sleeve, inner sleeve causes shearing force all by each guide
It bears, avoids bolt and cut so that the mechanism can not only provide axial tightening connection, additionally it is possible to transfer rotation torque.
The device compares common bolt fastening structure, which can transfer rotation torque, avoid bolt and bear to cut
Power.

Reference numeral
Connected piece -1, connected piece -2, housing -3, transition tapered sleeve -4, inner sleeve -5 connect bolt -6.
Specific embodiment
To make the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.Type of the present invention is further illustrated below in conjunction with attached drawing.
As Figure 1-Figure 4, pin bushing-type bolt connecting mechanism provided by the invention, the guide for carrying the conical surface with two, point
Not Wei transition tapered sleeve -4, inner sleeve -5, the connected piece -1 of transition tapered sleeve -4 and the connected piece -2 of inner sleeve -5 are first during initial installation
First contact, pulled using the axial tension that is generated in -6 rundown process of bolt is connected by inner sleeve -5 is axial, inner sleeve -5 to housing -
During 3 movements, connected piece -1, while interference volume is generated between connected piece -2, the Φ 2# of transition tapered sleeve -4 are outer, Φ
3# (such as Fig. 3) outside diameter generates expansion, and (such as Fig. 2) generates interference volume outside the Φ 2# of endoporus, housing -3 with connected piece -1,
And then the Φ 1# (such as Fig. 2) of housing -3 is caused to generate interference volume with the endoporus of connected piece -2, after the conical surface tenses in place, by bolt
It is tightened to prescribed torque, generates suitable interference volume inside and outside each connector between mating surface in radial direction, be axially formed tapered sleeve
Frictional force between the conical surface prevents connected piece from axially loosening, greatly improves the reliability of bolt fastening with this.Due to outer
Set, the presence of transition tapered sleeve, inner sleeve cause shearing force all to be born by each guide, avoid bolt and are cut so that the mechanism
Axial tightening connection can not only be provided, additionally it is possible to transfer rotation torque.
Novel bolt bindiny mechanism provided by the invention adds two layers of taper on the basis of existing bolt fastening structure
Guide, the increase by one of taper guide can bear shearing force, and two anti-can loosen ability axially increased.The Novel bolt
Bindiny mechanism has employs guide structure when being bolted.Compared to common bolt fastening structure, which can transfer rotation
Torque.Bolt is avoided to bear to shear.It improves bolted axial direction and resists the ability of loosening so that connected piece axially connects
Reliably.It is at low cost, it is whole non-maintaining.Shear pin, shear connector, end face tooth structure high processing costs, and shear latch structure dismounting all
More difficult, repair and maintenance is of high cost, which can accomplish whole non-maintaining.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, several improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
