Detailed description of the invention:
Fig. 1 is the utility model structure diagram.
Specific embodiment:
Referring to Fig.1, a kind of large torque rubs to surpass more turns round protection structure, including supported flange 1 and external splines flange 11, compresses
1 one end of flange is connect by fastening bolt with external splines flange 11, and 1 other end of supported flange passes through the first locating flange component 2
It is connect with 3 one end of internal spline flange, 3 other end of internal spline flange is connected by the second locating flange component 7 with external splines flange 11
Connect, between internal spline flange 3 and external splines flange 11 be equipped with the first friction plate 4, the second friction plate and third friction plate 6, first
Friction plate 4, the second friction plate and third friction plate 6 are spaced apart from each other and arranged in parallel, the first friction plate 4, the second friction plate
It is connect by spline with internal spline flange 3 with third friction plate 6, is equipped between internal spline flange 3 and external splines flange 11 and also sets
There are the first frictional disk 9, the second frictional disk 5, third frictional disk and the 4th frictional disk 8, the first frictional disk 9, the second frictional disk 5,
Three frictional disks and the 4th frictional disk 8 are spaced apart from each other setting formation with the first friction plate 4, the second friction plate and third friction plate 6 and rub
Dual face is wiped, the first frictional disk 9, the second frictional disk 5, third frictional disk and the 4th frictional disk 8 pass through spline and external splines flange
11 connections；The supported flange 1 is tightly connected by disc spring 13 and friction pair face pressure.The friction plate number is at least two
A, each friction plate configures a frictional disk, and the number of frictional disk than friction plate number more than one.The compression
Flange 1 and 11 junction of external splines flange are equipped with adjustment gasket 10.The supported flange 1 and the first locating flange component 2 it
Between be equipped with O-ring 12；O-ring 12 is equipped between the external splines flange 11 and the second locating flange component 7.The outer flower
Key flange 11 in shafting spindle nose or adapter flange connect.
The structure by supported flange 1, the first locating flange component 2, the second locating flange component 7, internal spline flange 3, rub
The components compositions such as pad, frictional disk, adjustment gasket 10, external splines flange 11, O-ring 12 and disc spring 13.Each friction plate (
One friction plate 4, the second friction plate and third friction plate 6) there are a frictional disk (the first frictional disk 9, the second frictional disk 5, third
Frictional disk and the 4th frictional disk 8) it is paired, a friction pair face is formed, friction pair area is bigger, and dual face number is got over
More, the torque of this structure transmitting is bigger.In this arrangement works, friction plate (rub by the first friction plate 4, the second friction plate and third
Pad 6) it is linked together with internal spline flange 3 by spline, and frictional disk (rub by the first frictional disk 9, the second frictional disk 5, third
Wipe disk and the 4th frictional disk 8) it is linked together with external splines flange 11 by spline, and supported flange 1 will rub by disc spring 13
Pad and frictional disk are pressed together, and in this way under the action of frictional force, the torque of unit can be transmitted by internal spline flange 3
To external splines flange 11.In the super torsion torque of specific adjusting, the decrement of disc spring 13 is adjusted by adjusting the thickness of gasket 10,
The moment of friction for generating design to make to form the normal pressure of requirement on the friction pair face of friction plate.When the torsion of unit transmitting
When square is more than the moment of friction of setting, each friction pair face generates opposite skidding, so that extra torque is uninstalled, to unit
Play the role of overload protection.In addition, locating flange component (the first locating flange component 2 and the second locating flange component 7) with
The stop portion design of phase accessory has wear-resisting skidding copper sheathing, which plays the role of bearing support when skidding, and prevents this
Structure seam allowance mating surface when skidding is worn, and is generated alignment deviation and is had an impact to unit.Locating flange component
It is all provided at (the first locating flange component 2, the second locating flange component 7) and 11 mating surface of supported flange 1 and external splines flange
It in respect of O-ring 12, prevents the greasy dirt in environment from entering between the rubbing surface of this inside configuration, subtracts the coefficient of friction in friction pair face
It is small, to influence the performance of this structure.When using this structure, internal spline flange 2 can be connect with the flexible member of shaft coupling, be made
For shaft coupling end flange use, can also internal spline flange 3 connect with adapter flange in shafting, external splines flange 11 and shafting
In spindle nose or adapter flange connection, as shaft system of unit a part be used alone.
Friction plate is connect by spline with internal spline flange 3, and frictional disk is connect by spline with external splines flange 11, multiple
Friction plate and friction panel surface formed antithesis rubbing surface, by the frictional force between antithesis rubbing surface by the torque in unit bearing from
Internal spline flange 3 is transmitted to external splines flange 11, and when transmitting that torque is excessive to be more than setting value, friction pair generates between face
It is opposite to skid, so that laying down torque extra in unit plays purpose to unit overload protection.
It is allowed to transmit torque by 13 pressing friction dual face of disc spring, it is opposite between friction plate when transmitting torque is excessive
It skids, to uninstall extra torque, plays the role of super torsion protection.
The decrement of disc spring 13, control are adjusted using the torque of bolt on the thickness or supported flange 1 of adjustment gasket 10
Normal pressure between friction plate dual face protects torque value so as to adjust the super torsion of the utility model.
Design has the copper sheathing with wear-resisting functions at internal spline flange 3 and 11 cooperation of external splines flange, to avoid this structure
Carry out it is super wrestle sliding during non-essential damage.
It is designed with O-ring 12 at locating flange component and 11 mating surface of supported flange 1 and external splines flange, prevents ring
Greasy dirt in border enters between the rubbing surface of this inside configuration, reduces the coefficient of friction in friction pair face, to influence this structure
Performance.
When super torsion protection structure disengages in conclusion this large torque rubs more, torque can be still transmitted, it is ensured that unit is normal
Operation, ensure that host does not generate driving phenomenon；It can bear multiple disengagement movement；It can automatically reset, without operation, eliminate overload
It, can be with the starting synchronous reset of host after torque；Breakaway torque precision is high and adjustable, and breakaway torque is mainly by the pressure for adjusting disc spring
Contracting amount is realized, because disc spring performance is stablized, degree of regulation and repeatable accuracy are high；Antithesis friction plate is more, and transmitting torque is big, is adjusted
Breakaway torque range it is wide, more adaptation large torque unit occasion.
