Description
Technical field
The present invention relates to a kind of mechanical load limiter.
Background technology
Torque work overload restriction to transmitting at present realizes that the machinery of overload protection is all generally clutch.Clutch
Limit for tonnage value be usually to determine in design, can not be adjusted according to requirements of one's work during use.
The content of the invention
In order to overcome above-mentioned deficiency, the present invention to provide a kind of mechanical load limiter, the torque work overload transmitted can be limited,
As needed limit for tonnage value can be adjusted again.
The technical solution adopted for the present invention to solve the technical problems is：Designed mechanical load limiter include coupling sleeve,
Holddown spring, output dish axle, thrust bearing, compress dish axle, input cylinder, adjusting nut, locking nut, one end of coupling sleeve with it is defeated
Enter a thread connection, middle part and the output dish axle of the coupling sleeve other end coordinate for gap, and thrust bearing is arranged in the middle part of coupling sleeve,
Holddown spring is located between the disk of thrust bearing and output dish axle, and the axle for compressing dish axle is provided with two sections of oppositely oriented screw threads,
Which couple with the screwed hole in input cylinder centre near one section of screw thread of disk, another section of screw thread and adjusting nut and locking nut
Connection, the disk and the middle part of the relative card of disk of output dish axle for compressing dish axle is recessed circle, and the recessed diameter of a circle is more than compression plate
The diameter of thread on the axle of axle.
Holddown spring described in the technical program can be video disc spring.
The present invention operation principle be：When the mechanical load limiter is installed, first pass through and screw coupling sleeve and be input into coupling for cylinder
Screw thread, makes holddown spring obtain certain pretension, so that the disk of output dish axle is contacted with the disk for compressing dish axle and produced certain
Normal pressure.Because coupling sleeve produces the moment of friction that moment of friction is consistently greater than thrust bearing, institute with the screw thread that couples of input cylinder
With coupling sleeve with input cylinder in the course of the work without relative motion.Start when certain direction rotation, due to compression plate when cylinder is input into
The recessed diameter of a circle in middle part of the disk of axle is more than the diameter of thread on the axle for compressing dish axle, so being easy to accomplish to be input into cylinder centre
Screwed hole to the friction drive produced by the screw thread of the compression dish axle of thread connection therewith, and input cylinder is to compressing dish axle
Disk produce friction drive sum, it is impossible to overcome output dish axle disk to compress dish axle disk produced by frictional resistance.This
When, compress dish axle and just produce to output panel direction of principal axis and make continuous moving, make the thrust between their disk more and more big, rub
Torque is also more and more big.When the moment of friction can drive output dish axle to rotate, the equal synchronous axial system of each part of the mechanical load limiter,
So as to the power for realizing the direction is transmitted.If there is unexpected overload, compress dish axle just produce to output panel it is axial enter one
Moved further, until adjusting nut withstands input cylinder, so, the thrust compressed between the disk of dish axle and output dish axle would not be after
Continuous to increase, moment of friction also will not continue to increase, and occur skidding, and realize overload protection function.The size of limit for tonnage, can pass through
The position for changing adjusting nut is just changed.
The invention has the beneficial effects as follows：Overload restriction can be made to the torque transmitted, again can as needed to limit for tonnage value
It is adjusted.
Description of the drawings
Fig. 1 is embodiments of the invention schematic diagram.
1. coupling sleeves in figure, 2. holddown spring, 3. export dish axle, 4. thrust bearing, 5. compress dish axle, be 6. input into cylinder, 7.
Adjusting nut, 8. locking nut.
Specific embodiment
It is seen in fig. 1, that the present invention applies example includes coupling sleeve（1）, holddown spring（2）, output dish axle（3）, thrust
Bearing（4）, compress dish axle（5）, input cylinder（6）, adjusting nut（7）, locking nut（8）.Coupling sleeve（1）One end with input cylinder
（6）Thread connection, middle part and the output dish axle of the other end（3）Coordinate for gap.Thrust bearing（4）Installed in coupling sleeve（1）In
Portion, holddown spring（2）Positioned at thrust bearing（4）With output dish axle（3）Disk between.Compress dish axle（5）Axle be provided with two sections
Oppositely oriented screw thread, its one section of screw thread and input cylinder near disk（6）The screwed hole connection in centre, another section of screw thread with
Adjusting nut（7）And locking nut（8）Connection.Compress dish axle（5）Disk with output dish axle（3）The relative card of disk middle part
For recessed circle, the recessed diameter of a circle is more than compression dish axle（5）Axle on the diameter of thread.Holddown spring（2）Using video disc spring.
When the mechanical load limiter is installed, first pass through and screw coupling sleeve（1）With input cylinder（6）Connection screw thread, make compression bullet
Spring（2）Certain pretension is obtained, so that output dish axle（3）Disk with compress dish axle（5）Disk contact and produce it is certain just
Pressure.Because of coupling sleeve（1）With input cylinder（6）Connection screw thread produce moment of friction be consistently greater than thrust bearing（4）Frictional force
Square, so coupling sleeve（1）With input cylinder（6）In the course of the work without relative motion.When input cylinder（6）Start to certain direction to rotate
When, due to compressing dish axle（5）Disk the recessed diameter of a circle in middle part more than compress dish axle（5）Axle on the diameter of thread, so easily
In accomplish be input into cylinder（6）Compression dish axle of the screwed hole in centre to thread connection therewith（5）Screw thread produced by friction
Driving force, and input cylinder（6）To compressing dish axle（5）Disk produce friction drive sum, it is impossible to overcome output dish axle（3）'s
Disk is to compressing dish axle（5）Disk produced by frictional resistance.Now, compress dish axle（5）Just produce to output dish axle（3）Make in direction
Continuous moving, makes the thrust between their disk more and more big, and moment of friction is also more and more big.When the moment of friction being capable of band
Dynamic output dish axle（3）During rotation, the equal synchronous axial system of each part of the mechanical load limiter, so as to the power for realizing the direction is transmitted.If
There is unexpected overload, compress dish axle（5）Just produce to output dish axle（3）Direction is further moved, until adjusting nut（7）Top
Cylinder is input into firmly（6）And stop, making compression dish axle（5）With output dish axle（3）Disk between thrust would not continue increase, rub
Wipe torque also to will not continue to increase, and occur skidding, realize overload protection function.The size of limit for tonnage, can adjust spiral shell by changing
It is female（7）Position be just changed.
