Abstract
The invention discloses a hollow harmonic speed reducer, which comprises a harmonic speed reducer body, wherein a connecting shaft is arranged in the harmonic speed reducer body; a working end of the connecting shaft is connected with a wave generator through a fastening piece; a through hole is arranged in the connecting shaft and is communicated with a circular hole in the wave generator; and threads are arranged on an output end of the connecting shaft. According to the hollow harmonic speed reducer, not only are manufacturing materials of the connecting shaft saved and manufacturing cost of the harmonic speed reducer reduced, but also the center of the harmonic speed reducer is hollow; when in wiring, a cable can penetrate through the center of the harmonic speed reducer, so that the cable can be prevented from being exposed outside, and is not easy to damage, the length of the cable is reduced, and unnecessary waste is avoided; and the connection of other parts and the output end of the connecting shaft is convenient.
Description
Technical field
The present invention relates to a kind of speed reducer, relate in particular to a kind of harmonic wave speed reducing machine, belong to the transmission device technical field.
Background technique
Speed reducer is that a kind of power is passed on mechanism, utilizes the velocity transducer of gear, the winding number of electric motor is decelerated to desired winding number, and obtain the mechanism of big torque.Speed reducer of a great variety, model is different, and variety classes has different purposes; Wherein harmonic wave speed reducing machine is a kind of a kind of novel speed reducer that utilizes the planetary pinion transmission principle to grow up; Because its bearing capacity is high, velocity ratio is big, and volume is little, in light weight; High these distinct advantages of stable drive and transmission accuracy make harmonic wave speed reducing machine be widely used in industries such as electronics, space flight and aviation, robot.
The coupling shaft of existing harmonic wave speed reducing machine is generally solid; When harmonic wave speed reducing machine connects when needing trace arrangements between two parts that need transmission; The electric wire installation of can only arranging in the outside of harmonic wave speed reducing machine so not only makes cable etc. be exposed to the outside, damages easily; But also increased the length of cable, caused unnecessary waste.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of when carrying out trace arrangements, the hollow type harmonic wave speed reducing machine at the harmonic wave speed reducing machine center that cable can pass.
Technical solution of the present invention is achieved in that a kind of hollow type harmonic wave speed reducing machine, comprises the harmonic wave speed reducing machine body, is provided with coupling shaft in the said harmonic wave speed reducing machine body, and the working end of said coupling shaft is connected with wave-generator through fastening piece; Have through hole on the said coupling shaft; The circular hole that has on said through hole and the wave-generator links.
Preferably, the output terminal of said coupling shaft is provided with screw thread.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Hollow type harmonic wave speed reducing machine of the present invention because the working end of coupling shaft is connected with wave-generator through fastening piece, has through hole on the coupling shaft; The circular hole that has on through hole and the wave-generator links, and has not only practiced thrift the raw making materials of coupling shaft, has reduced the fabricating cost of harmonic wave speed reducing machine; And make the harmonic wave speed reducing machine center hollow, when conducting transmission line was arranged, cable can pass at the center from harmonic wave speed reducing machine; Avoided cable to be exposed to the outside; Make cable not fragile, but also reduced the length of cable, avoided unnecessary waste; Because the output terminal of coupling shaft is provided with screw thread, made things convenient for being connected of miscellaneous part and coupling shaft output terminal.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of hollow type harmonic wave speed reducing machine of the present invention;
Wherein: 1, harmonic wave speed reducing machine body; 2, coupling shaft; 3, fastening piece; 4, wave-generator; 5, through hole; 6, circular hole; 7, screw thread.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of hollow type harmonic wave speed reducing machine shown in accompanying drawing 1 comprises harmonic wave speed reducing machine body 1, is provided with coupling shaft 2 in the said harmonic wave speed reducing machine body 1, and the working end of said coupling shaft 2 is connected with wave-generator 4 through fastening piece 3; Have through hole 5 on the said coupling shaft 2; The circular hole 6 that has on said through hole 5 and the wave-generator 4 links; The output terminal of said coupling shaft 2 is provided with screw thread 7.
Hollow type harmonic wave speed reducing machine of the present invention, the raw making materials of having practiced thrift coupling shaft 4 has reduced its manufacture cost; When conducting transmission line was arranged, cable can pass in through hole 5 and circular hole 6, has avoided cable to be exposed to the outside, makes cable not fragile, but also has reduced the length of cable, has avoided unnecessary waste; Miscellaneous part is connected with the output terminal of coupling shaft 4 through screw thread 7, and is convenient and practical.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
