Specific implementation mode
It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model
Mode is applied to elaborate to the utility model.
As depicted in figs. 1 and 2, the embodiments of the present invention provide a kind of compliant wheel with overload protection function,
The compliant wheel with overload protection function, including ontology 10, connection core 20 and connector sleeve 30.Ontology 10 is cylindrical in shape, ontology
10 have nozzle end 11 and cylinder bottom end 12, and the external tooth for the interior tooth engagement with rigid wheel is provided on the outer wall at nozzle end 11
13；Connection core 20 is fixed on a bottom end 12, and connector sleeve 30 is sheathed on connection core 20 and for connecting with the input shaft of load 200
It connects.Connection core 20 towards load 200 one end end face on offer threaded hole 22；It is offered on connection core 20 from connection core 20
Peripheral surface extend radially through the guide groove 32 of threaded hole 22；The hole wall of the endoporus of connector sleeve 30 and 32 axially opposite position of guide groove
Set that offer multiple limiting cards recessed, multiple recessed circumferential directions of limiting card are uniformly distributed；Be provided with spring 34 in guide groove 32, spring 34 radially towards
Outer one end is provided with the decorative pearl on top of an official cap 33, and one end of 34 radial inward of spring is provided with push rod 35, and spring 34 is in compressive state always,
To make inner hole wall of the decorative pearl on top of an official cap 33 with certain force tight against connector sleeve 30 always；Threaded hole 22 is bolted with adjustment mother 40, and adjustment mother 40 leans on
One section of formation round table surface 41 of nearly ontology 10, round table surface 41 are abutted with the lower end of push rod 35, by knob adjustment mother 40 to change
The axial position of adjustment mother 40, makes round table surface 41 change the radial position of push rod 35 by being contacted with push rod 35, to change
The decrement of spring 34.
As described above, in compressive state spring 34 make the decorative pearl on top of an official cap 33 with certain force be partially submerged into limiting card it is recessed in,
When the torque of connector sleeve 30 is less than predetermined torque, which is unlikely to the elastic force for making the decorative pearl on top of an official cap 33 overcome spring 34 and the at this time decorative pearl on top of an official cap
33 parts to be embedded at limiting card recessed, at this point, connector sleeve 30 is rotated synchronously with core 20 is connect；When connector sleeve 30 torque be more than etc.
When predetermined torque, torque makes the decorative pearl on top of an official cap 33 overcome the elastic force of spring 34 and compressed spring 34, the decorative pearl on top of an official cap 33 from limiting card it is recessed in take off
Go out, at this point, connection core 20 is relatively rotated with connector sleeve 30, to play the role of overload protection.
It should be noted that：In design, the peak torque that compliant wheel can be born should be made to be more than predetermined torque, such as
This, when loading 200 normal operation, the torque of connector sleeve 30 is less than predetermined torque, turns at this point, compliant wheel is synchronous with load 200
Dynamic, compliant wheel is that load 200 provides power；When loading 200 all standing, the torque of connector sleeve 30 is pre- because 200 all standings of load are more than
If torque, which makes the decorative pearl on top of an official cap 33 move radially inwardly with from the recessed middle abjection of limiting card, so that compliant wheel and load 200
Rotation separation, to make ontology 10 because excessive by torque due to excessive torque caused by all standing will not be made to pass to ontology 10
And it damages.In addition, carrying out the decrement of adjustment spring 34 by adjusting the axial position of adjustment mother 40, so as to adjust predetermined torque
Size.In this way, when ontology 10 can be because bearing high torque, the decrement of spring 34 is set to increase, the decorative pearl on top of an official cap 33 is not easy from limit
Block recessed abjection, makes bullet when ontology 10 cannot bear high torque to increase compliant wheel and the torque of 200 transmission of load
The decrement of spring 34 reduces, and the decorative pearl on top of an official cap 33 is easy from the recessed abjection of limiting card, to reduce the torsion of compliant wheel and 200 transmission of load
Square improves overload and keeps function.
In a preferred embodiment of the utility model, as shown in Figure 1, one end of 40 direction load 200 of adjustment mother
End face offers the polygonal hole 42 for exerting a force for spanner, for example, interior hexagonal hole.In this way, tune can be screwed by die nut
Whole female 40 to adjust the decrement of spring 34.
In a preferred embodiment of the utility model, as shown, cylinder bottom end 12 offers through-hole；It is remote to connect core 20
One end from load 200 is formed with terminal pad 21, and the inside attaching of terminal pad 21 and cylinder bottom end 12 simultaneously passes through fastener and cylinder bottom
End 12 is fixedly connected；One end of connection core 20 towards load 200 is protruded from across through-hole outside ontology 10,30 company of being sheathed on of connector sleeve
It connects core 20 and protrudes from the part outside ontology 10.It is formed with external screw thread 23 on connection core 20, connects and be arranged on core 20 and external screw thread
One end of 23 spacing rings 36 being threadedly coupled, connector sleeve 30 towards ontology 10 is fixed with backstop lid 31, and spacing ring 36 limits
Between backstop lid 31 and connector sleeve 30.Thrust bearing 37 is additionally provided between spacing ring 36 and backstop lid 31.In the present embodiment
In, on the one hand, connector sleeve 30 is limited by spacing ring 36 and connects the axial internal clearance between core 20 and ontology 10；It is another
Aspect, thrust bearing 37 can be in connector sleeves 30 and the abrasion of reduction between the two when connecting the relative rotation of core 20；Connect core 20
It is fixedly connected with 12 inside of cylinder bottom end by terminal pad 21, terminal pad 21 has certain support to cylinder bottom end 12, to reduce
The deformation of cylinder bottom end 12, improves the rigidity of a bottom end 12.
Above example is only the exemplary embodiment of the utility model, is not used in limitation the utility model, this practicality is new
The protection domain of type is defined by the claims.Those skilled in the art can be in the essence and protection domain of the utility model
It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling new in this practicality
In the protection domain of type.
