Abstract
The utility model relates to a hollow harmonic speed reducer. The hollow harmonic speed reducer comprises a harmonic speed reducer body; a connecting shaft is arranged in the harmonic speed reducer body; the working end of the connecting shaft is connected with a wave generator through a fastening piece; a through hole is formed in the connecting shaft; the through hole is communicated with a round hole which is formed in the wave generator; and screw threads are formed in the output end of the connecting shaft. By adopting the hollow harmonic speed reducer, the manufacturing raw material of the connecting shaft is saved; the manufacturing cost of the harmonic speed reducer is reduced, and moreover, the center of the harmonic speed reducer is hollow; when wires are arranged, a cable can pass through the center of the harmonic speed reducer, so that the cable can be prevented from exposing outside, the cable is hard to damage, and moreover, the length of the cable is reduced, unnecessary waste is avoided, and the connection between other parts and the output end of the connecting shaft is convenient.
Description
Technical field
The utility model relates to a kind of speed reducer, relates in particular to a kind of harmonic wave speed reducing machine, belongs to the transmission device technical field.
Background technique
Speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, the winding number of electric motor is decelerated to desired winding number, and obtain the mechanism of larger torque.Speed reducer of a great variety, model is different, 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 Gear Transmission principle to grow up, because its bearing capacity is high, velocity ratio is large, and volume is little, lightweight, high these distinct advantages of stable drive and transmission accuracy are so that harmonic wave speed reducing machine is widely used in the 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 so that cables etc. are exposed to the outside, easily damage, but also increased the length of cable, caused unnecessary waste.
The model utility content
The utility model purpose is to provide a kind of when carrying out trace arrangements in order to overcome the deficiencies in the prior art, the hollow type harmonic wave speed reducing machine at the harmonic wave speed reducing machine center that cable can pass.
