Abstract
The invention discloses a kind of Combined locknuts, including locking nut, modular nut, rubber sheet gasket.When nut is assembled and is tightened, the recessed round platform of locking nut squeezes the dome platform for dividing valve nut in modular nut, valve nut stress is divided to generate along bolt radial displacement, bolt and the screw thread back lash of valve nut is divided to be eliminated, the external screw thread tight mesh of the internal thread and bolt that divide valve nut is mutually locked, simultaneously under the action of locking nut pretightning force, the frictional force divided between valve nut and bolt internal and external threads in modular nut increases, effectively helical is prevented to revolve to move back because of vibration and loosens, achievees the effect that good fastening and anti-loose.
Description
Technical field
The invention belongs to technical field of fastening, are related to a kind of Combined locknut.
Background technology
Fastener is for being fastenedly connected and widely used a kind of machine components.Various mechanical parts are in being linked and packed
All it be unable to do without fastener.Existing fastener is mostly that common screw bolt and nut connects fastening means, i.e. plain bolt pair.Tightly
Firmware is brought conveniently for mechanical industry, but inevitable weakness there are one it, can voluntarily be loosened in high vibration, is caused
So that component or equipment is damaged in operation or even leads to serious accident.
Common nut anti-looseness mode mainly has：Rubbing, locking, mechanical stop is locking, riveting rushes that locking, helicitic texture is locking
Etc., but cannot extensive use because of each in the presence of some disadvantages, use condition being caused to be restricted.
Invention content
Goal of the invention：A kind of Combined locknut is provided, simple in structure and easy for installation, anti-loosing effect is good and not by item
Part limits.
Technical solution：To realize above-mentioned technical purpose and the technique effect, the present invention is real by the following technical programs
It is existing.
A kind of Combined locknut, it is characterised in that：Including locking nut, modular nut, rubber sheet gasket.Described
There is an indent truncated cone-shaped cavity in the inside of locking nut one end, and there is flange face in outside；Modular nut is by supporting sleeve and several points
Valve nut forms；The supporting sleeve is hexagon, and inside has hexagon cavity, the hexagon cavity top to have
There is a circular hole at one gland, the gland center；Described divides valve nut to be to have the convex of dome platform by a complete one end
Nut is circumferentially evenly divided into the wherein valve after several valves；It is described when dividing valve nut according to before being divided on knurled nut
It is corresponding to be subsequently placed in supporting sleeve, supporting sleeve axially and radially constraint the following group at modular nut.
The Combined screw box thread is identical as the corresponding main geometric parameters of knurled nut screw thread.
The taper of the recessed round platform of the locking nut is identical as the taper of dome platform of knurled nut.
The upper bottom surface radius of the recessed round platform of the locking nut is less than the upper bottom surface radius of the dome platform of knurled nut.
The bottom radius surface of the recessed round platform of the locking nut is less than the bottom radius surface of the dome platform of knurled nut.
The circle hole radius of the support jacket gland is more than the bottom radius surface of the dome platform of knurled nut.
Corresponding knurled nut size one when the interior hexagon cavity of the supporting sleeve is with before dividing valve nut divided
It causes.
Each two has equal circumferential gap between dividing valve nut in the supporting sleeve.
Advantageous effect：Divide valve nut can be along bolt radial displacement in modular nut；When nut is assembled and is tightened, lock
The tight recessed round platform extruding of nut divides valve nut dome platform, and valve nut stress is divided to generate along bolt radial displacement, bolt and divides valve nut
Screw thread back lash be eliminated, the external screw thread tight mesh of the internal thread and bolt that divide valve nut is mutually locked, while being locked
Under the action of tight nut pretightning force, the frictional force divided between valve nut and bolt internal and external threads increases, and effectively prevents helical because of vibration
And revolve and move back and loosen, achieve the effect that good fastening and anti-loose.Flange face and rubber sheet gasket are used cooperatively with good close
Effect is sealed, effectively the harmful substances such as rainwater, sundries is prevented to enter inside modular nut, screw-thread rust is prevented and then extends nut
Service life.

Specific implementation mode
As shown in figures 1 and 3, a kind of Combined locknut includes locking nut 1, rubber sheet gasket 2, modular nut
10.The inside of 1 one end of locking nut has a recessed round platform 7, outside to have flange face 5；Three points of valve nuts 4 of modular nut 10 by
It is corresponding on knurled nut 9 when according to before being divided to be subsequently placed in supporting sleeve 3, each divide the rotation of the screw thread of valve nut 4
Direction is all consistent, and each two has equal circumferential gap 11 between dividing valve nut 4, in the constraint of the gland and circular hole of supporting sleeve 3
Under divide valve nut 4 that can only generate the radial displacement along bolt 8；Because of the dome of the taper and knurled nut 9 of the recessed round platform of locking nut 7
The taper of platform is identical, thus the medial surface of the recessed round platform of locking nut 7 with divide the lateral surface of valve nut dome platform 6 that can overlap.
Combination nut 10 is first installed when assembly, then places rubber sheet gasket 2, last installation locking nut 1.Locking nut 1
When being tightened, the medial surface of the recessed round platform of locking nut 7 squeezes the lateral surface of three points of valve nut dome platforms 6, modular nut 10
It is internal that 4 stress of valve nut is divided to generate the radial displacement along bolt 8, bolt 8 and the screw thread back lash of valve nut 4 is divided to be disappeared
It removes, the external screw thread tight mesh of the internal thread for dividing valve nut 4 and bolt 8 is mutually locked, while in the pretightning force of locking nut 1
Under effect, the frictional force divided between 8 internal and external threads of valve nut 4 and bolt increases, and effectively prevention helical, which revolves to move back because of vibration, loosens, and reaches
To good fastening and anti-loose effect.Flange face 5 and rubber sheet gasket 2, which are used cooperatively, has good sealing effect, effectively
It prevents the harmful substances such as rainwater, sundries from entering inside modular nut, prevent screw-thread rust and then extends the service life of nut.
