It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments creates.
A kind of antitorque shaft coupling, as shown in Fig. 1 to 2, including shaft coupling ontology, which includes intermediate deformation
Portion 1 and the fixed part 2 at both ends；The fixed part 2 includes linkage section 3 and changeover portion 4, and changeover portion 4 is bores tubular structure, mistake
The major diameter one end for crossing section is in 1 side of deformations；Helical cut slot 5 is along the circumferential direction offered on changeover portion；The fixation
2 inner wall of portion is equipped with metal connector sleeve 6, and the part which stretches out the fixed part outer end is equipped with connecting hole 7.
The fixed part 2 at above-mentioned deformations 1 and both ends is an integral molding structure, and structural strength is high, and stability is good, due to being one
Body formula structure design, is not in the stress concentration of junction, and service life is longer.
Above-mentioned shaft coupling ontology is made of rubber material, and shaft coupling ontology itself has certain flexibility, by torsion
When, there is deformability, be hardly damaged.
The depth of above-mentioned helical cut slot 5 is preferably the 1/3-1/2 of 4 wall thickness of changeover portion.Because helical cut slot
Depth is unsuitable too deep, if groove depth is excessive, changeover portion easily occurs disconnected when by pulling force or torsion at helical cut slot
It splits, if groove depth is too small, can not play the good anti-torsion of helical cut slot and the deformability of stretch-proof, be not achieved best
Antitorque effect.
It should be noted that being equipped with helical cut slot 5 at changeover portion, with 1 common mating reaction of deformations, effectively improve
The anti-twisting property of this shaft coupling, changeover portion alleviate burden during deformations stress, are equivalent to and have shared a part of torsion, protect
Deformations stress equalization is demonstrate,proved, shaft coupling is hardly damaged.
Above-mentioned deformations 1 are bellows-like structure, and 9 height of wave crest is more than 10 height of trough.Due to bending or
During torsion, the deformation on shaft coupling outer circumference surface is bigger than its inside deflection, therefore, at excircle needs higher structure strong
Degree, and ensure that the deflection than inside bigger can be generated at excircle, it could preferably ensure the work of shaft coupling monolithic stability
Make, be not susceptible to damage.Therefore, crest height is more than trough height, so that wave crest energy opposed valleys generate the deformation of bigger
Amount, meanwhile, section is greater than section at trough at wave crest, to improve its intensity.
The crest location of above-mentioned deformations 1 is equipped with reinforcing ring 8.Reinforcing ring 8 is preferably provided inside wave crest.By set
Reinforcing ring, effectively raise the anti-twisting property at deformations excircle, and impact resistance is also significantly strengthened, shaft coupling
Crest location of the device at deformation position is not easy to break, it is ensured that its permanent service life.
In general, becket or elastomeric nonmetallic ring of the reinforcing ring 8 for spring steel material.Since reinforcer also has in itself
There is certain deformability, do not interfere with deformation quantity of the deformations in stress, complement each other with deformations so that shaft coupling
Anti-twisting property greatly promotes.
The invention is simple in structure, reasonable design, and the fixed part at deformations both ends is used for connecting with external axis body, and
Deformations have good structural strength in itself, and anti-twisting property is strong, this shaft coupling has been effectively ensured and the complicated work such as has been turned round in tension
It is not easy to damage under condition, stable and reliable in work, service life is long.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection domain within.
