When in overload or heavy condition, since its overload protection effect is undesirable so that mechanical organ still can be by different degrees of
Damage.
Utility model content
The utility model provides a kind of big torque radial peg overload-release clutch, and not only transmission operation torque is big, overload is protected
It is good and simple in structure, easily fabricated to protect performance, and it is more safe and reliable to work.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of big torque radial peg safety
Clutch, including positioning sleeve 1, key 2, housing 3, inner sleeve 4, radial peg 5, compression spring 6 and cushion block 7 are set in the outer circle of the positioning sleeve 1
Uniformly distributed radial blind holes are equipped with, the cushion block 7, compression spring 6, radial peg 5 are sequentially arranged at the radial direction of the positioning sleeve 1 from inside to outside
In blind hole, radial trapezoid boss is provided on the end face of the radial peg 5, the positioning sleeve 1 is mounted on the interior of the housing 3
Kong Zhong, be provided on the housing 3 and the radial blind holes corresponding position with the matched groove of the trapezoid boss, it is described in
Set 4 is fixed on together by key 2 and positioning sleeve 1.The utility model provides a kind of big torque radial peg overload-release clutch,
Not only transmit that operation torque is big, overload protection dependable performance, but also simple in structure, the operation is stable, easily fabricated and more real
With and safety.
Further, the radial peg 5 has the basic structure of general cylindrical pin, and there are one prolong for setting in one end
The radial trapezoid boss on cylindrical surface is extended to, and there are one axial blind holes in its other end center position setting.
Further, at least one set of radial blind holes are provided in the outer circle of the positioning sleeve 1, every group of blind hole is by same
Four, six or eight uniformly distributed symmetrical radial blind holes are constituted on one circumference.
Further, it is arranged in the outer circle of the positioning sleeve 1 to every group of radial blind holes equidistant parallel.
Further, the housing 3 correspond to be provided at above-mentioned radial blind holes position it is matched with above-mentioned trapezoid boss
Groove.
Advantageous effect caused by the utility model is：
The utility model is realized using the method for housing and radial voussoir pin and the mutual wedge pressure of positioning sleeve transmits torque, no
But with reliable overload protection performance, and transmit operation torque it is big, it is more safe and practical and simple in structure, zero
Component is few, installation is easy.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the front view of radial peg.
In figure：1- positioning sleeves, 2- keys, 3- housings, 4- inner sleeves, 5- radial pegs, 6- compression springs, 7- cushion blocks.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, so that the advantages of the utility model and feature is easier to be readily appreciated by one skilled in the art.Based on this reality
With the embodiment in novel, any technical person familiar with the field do not obtained by creative work it is all other
Embodiment shall fall within the protection scope of the present invention.
As Figure 1-Figure 2, the present embodiment provides a kind of big torque radial peg overload-release clutch, including positioning sleeve 1, key 2,
Housing 3, inner sleeve 4, radial peg 5, compression spring 6 and cushion block 7 are provided with one group totally six in the outer circle of the positioning sleeve 1（At least four
It is a）Uniformly distributed symmetrical radial blind holes, the cushion block 7, compression spring 6, radial peg 5 are sequentially arranged at the positioning sleeve from inside to outside
In 1 radial blind holes, wherein the radial peg 5 has the basic structure of general cylindrical pin, in one end there are one settings
Extend to the radial trapezoid boss on cylindrical surface（Referring to Fig. 2）, and there are one axial blind in its other end center position setting
The end face center position in hole, the cushion block 7 is provided with a same axial blind hole, and the compression spring 6 is arranged in radial peg 5
In the axial blind hole of cushion block 7, the positioning for compression spring 6 and guiding, radial peg 5 can be realized by compression press spring 6 in positioning sleeve 1
Radial blind holes in move inwards.
The positioning sleeve 1 is mounted on using its outer circle in the endoporus of housing 3, and positioning sleeve 1 is corresponded on the endoporus of housing 3
At radial blind holes position, there are six the matched radial groove of trapezoid boss with radial peg 5, the outer circles of the inner sleeve 4 for setting
There are one positioning spline, the inner sleeves 4 to be fixed on together by key 2 and positioning sleeve 1 for upper setting.
Preferably, the radial peg 5 with inside and outside nested big small pressure spring 6 can be provided in the axial blind hole of cushion block 7 simultaneously,
The numerical value of operation torque or overload protection torque for adjusting clutch.
The working method of the utility model is：In the case of moment overload or overload occurs, the trapezoid boss of radial peg
It is subject to the huge radial pressure from housing, under this force effect, radial peg is pressed rapidly along the radial through-hole of positioning sleeve
Contracting compression spring simultaneously moves inwards, is completely disengaged until separating until the trapezoid boss of radial peg and the groove of housing endoporus, outer at this time
Idle running or slipping state are realized between set and radial peg, that is, positioning sleeve, realizes overload protective function, when instantaneous load or overload disappear
After mistake, the compression spring of compression pushes rapidly radial peg along the radial blind holes of positioning sleeve because of elasticity recovery and is displaced outwardly, until
The trapezoid boss of radial peg is re-introduced into the corresponding groove of housing, realizes that clutch continues to transmit the effect of torque.
The above is only the preferred embodiment of the utility model only, however it is not limited to the utility model, it is all in this practicality
Within novel spirit and principle, any modify or supplement that the art makes described embodiment, equivalent replacement or
Improve by a similar method etc., it should be included within the scope of protection of this utility model.
