Description
Technical field
The present invention relates to a kind of gear structure, more particularly to a kind of overload self-destruction gear belongs to mechanical equipment technical field.
Background technology
Gear is the common transmission device of machinery field, and prior art geared system is made of many gear-linkeds, structure
It is accurate complicated, and higher price.When gear drive, it sometimes appear that the mechanical breakdowns such as overload, when load exceeds the destruction of gear
Gear structure can be destroyed when intensity, and gear is made to scrap.More seriously, overload can be transmitted along the drive path of gear, be made
Follow-up gear may be because overload and destroy, and continuous bigger is caused to lose.Especially because machinery inertial acts on, even if
It was found that stopping actuating unit operating when failure immediately, each gear on gear set can be also rotated further under effect of inertia, be made
At inevitable loss.Obviously, it would be desirable to a kind of geared system with overload protection function.
Invention content
In view of the deficiencies of the prior art, a kind of overload self-destruction gear provided by the invention leads between gear mass and gear shaft
It crosses the lower self-destruction pin of intensity to be connected, when gear overload occurs, self-destruction pin destroys first because intensity is relatively low, to cut
Broken teeth wheel drive path, protects follow-up gear not to be destroyed, and design is simple ingenious, and function and effect are good, and of low cost, logical
It is strong with property, it is widely portable to all kinds of geared systems.
The present invention be realize technical purpose the technical solution adopted is that：A kind of overload self-destruction gear, including gear mass (1) and
Gear shaft (2), the overload self-destruction gear further include spider (3) and self-destruction pin (4), and the spider (3) is open column shape
Structure, the outer surface of the spider (3) coordinate with the centre bore clearance fit of gear mass (1) or transition, the gear shaft (2)
Centre bore across spider (3), and be connected with spider (3) by connecting key (5), the spider (3) and gear mass
(1) corresponding position is equipped with axis hole, and the spider (3) is connected with gear mass (1) by the self-destruction pin (4) across axis hole,
The breakdown strength of the self-destruction pin (4) is less than the breakdown strength of gear mass (1).
A kind of overload self-destruction gear, the strength of materials of the self-destruction pin (4) are less than the strength of materials of gear mass (1).
A kind of overload self-destruction gear is located on the self-destruction pin (4) at the interface of spider (3) and gear mass (1) and sets
There are weakened segment (41), the cross section of the weakened segment (41) to be less than the cross section at other positions on self-destruction pin (4).
A kind of overload self-destruction gear, the weakened segment (41) are the annular recess set on self-destruction pin (4) surface.
The cross section of a kind of overload self-destruction gear, the annular recess is triangle.
Be equipped with internal thread in the axis hole of overload self-destruction gear, the spider (3) and/or gear mass (1) a kind of, it is described from
The corresponding position ruined on pin (4) is equipped with external screw thread, external screw thread and spider (3) and/or the gear mass (1) of the self-destruction pin (4)
Internal thread mutually screw.
Compared with prior art, the beneficial effects of the present invention are：
1, increase center dish structure between gear mass and gear shaft, it is lower certainly by intensity between spider and gear mass
It ruins pin to be connected, when gear overload occurs, self-destruction pin destroys first because intensity is relatively low, to cut off gear drive road
Line protects follow-up gear not to be destroyed, and design is simple ingenious, and function and effect are good.
2, self-destruction pin may be designed as the strength of materials that the strength of materials is less than gear mass, make self-destruction pin in overload prior to gear
Body destroys；Can not also change the material of self-destruction pin, but the smaller weakened segment in cross section is set on self-destruction pin, when overload
Weakened segment self-destruction, the mode that weakened segment is arranged is more simple and convenient, and design can be required different according to different antioverloadings
The weakened segment in section, more flexible practicality.
3, self-destruction pin is connected with spider and gear mass by screw thread, easy for installation；When self-destruction pin destroys, it is also convenient for
It replaces.
4, overload self-destruction gear can be made into standard member, be widely used in all kinds of geared systems, before having wide application
Scape and good economic benefit.

Fig. 2 is the structural schematic diagram of the self-destruction pin of the overload self-destruction gear of the present invention.
Reference sign：1- gear masses, 2- gear shafts, 3- spiders, 4- self-destruction pins, 41- weakened segment, 5- connecting keys.
Specific implementation mode
Below in conjunction with the accompanying drawings, technical solution provided by the invention is further described, makes those skilled in the art
Member can be better understood from the present invention and can be practiced.
Referring to Fig. 1, a kind of overload self-destruction gear provided by the invention, including gear mass 1, gear shaft 2, spider 3 and from
Ruin pin 4.Wherein, spider 3 is open column shape structure, and outer surface coordinates with the centre bore clearance fit of gear mass 1 or transition；
Gear shaft 2 passes through the centre bore with spider 3, and is connected with spider 3 by connecting key 5；Spider 3 and gear mass 1
Corresponding position is equipped with axis hole, and spider 3 passes through the self-destruction pin 4 of axis hole to be connected with gear mass 1, and the breakdown strength of self-destruction pin 4 is low
In the breakdown strength of gear mass 1.When gear overload occurs, self-destruction pin destroys first because intensity is relatively low, to cut off tooth
Drive path is taken turns, to which the follow-up gear of effective protection is not destroyed.
A kind of overload self-destruction gear provided by the invention, the strength of materials that the material of self-destruction pin 4 can be arranged are less than gear mass 1
The strength of materials, when to realize overload self-destruction pin 4 prior to gear mass 1 destroy, protect follow-up gear not to be destroyed.
A kind of overload self-destruction gear provided by the invention, can not also change the material of self-destruction pin, but be set on self-destruction pin 4
Weakened segment 41 is set, the cross section of weakened segment 41 is less than the cross section at other positions on self-destruction pin 4.Therefore, when overload, self-destruction pin is first
First destroyed in weakened segment.The mode that weakened segment is arranged is more simple and convenient, and can require to design according to different antioverloadings
The weakened segment of different cross section, more flexible practicality.
Further preferably it is arranged, weakened segment 41 is the annular recess set on 4 surface of self-destruction pin, this design makes self-destruction pin
Symmetrical configuration, stress equalization；It sets the cross section of annular recess to triangle, can make weakened segment 41 that there is most plane of weakness
Layer is cut off from most plane of weakness when self-destruction, to more accurately realize overload protection function.
A kind of overload self-destruction gear provided by the invention, can be arranged internal thread in the axis hole of spider 3 or gear mass 1,
Internal thread can also be set simultaneously in the axis hole of spider 3 and gear mass；Outer spiral shell is arranged in corresponding position on self-destruction pin 4
Line, the external screw thread of self-destruction pin 4 and the internal thread of spider 3 or gear mass 1 are mutually screwed and are fixed.Self-destruction pin and spider and gear
Body is connected by screw thread, easy for installation；When self-destruction pin destroys, it is also convenient for replacing.
