According to the harmonic speed reducer, an overall structure is optimized so as to be more compact, the volume of the harmonic speed reducer is reduced, the space occupation is reduced, manufacturing materials are reduced, the output is more stable and accurate, and the stability and the accuracy of working of the harmonic speed reducer are increased. The harmonic speed reducer has large rigidity and strength.
Description
Technical field
The present invention relates to a kind of harmonic wave speed reducing machine, particularly a kind of harmonic wave speed reducing machine of tape input axle belongs 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, and 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, stable drive and high these distinct advantages of transmission accuracy, makes harmonic wave speed reducing machine be widely used in industries such as electronics, space flight and aviation, robot.
Existing harmonic wave speed reducing machine has the harmonic wave speed reducing machine of tape input axle and the harmonic wave speed reducing machine of not tape input axle, and the harmonic wave speed reducing machine that nowadays uses is generally the harmonic wave speed reducing machine of tape input axle.But the harmonic wave speed reducing machine of tape input axle in the past; Its overall structure is compact inadequately, not only causes the harmonic wave speed reducing machine volume bigger, has increased raw making materials when having increased space hold; But also cause output stable inadequately, accurate, influenced the stability and the accuracy of harmonic wave speed reducing machine work.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: the harmonic wave speed reducing machine that has proposed a kind of tape input axle of compact overall structure.
Technical solution of the present invention is achieved in that a kind of harmonic wave speed reducing machine of tape input axle, comprises input shaft, wave-generator, internal end cover, flexbile gear, flexible bearing, firm wheel, criss-crossing roller bearing, outer end cap and angular contact bearing; The working end of said input shaft is provided with wave-generator; The outside of said wave-generator is provided with internal end cover; Said wave-generator is provided with flexbile gear; Be provided with flexible bearing between said wave-generator and flexbile gear; Said flexbile gear is provided with firm wheel; Be provided with the criss-crossing roller bearing between said flexbile gear and firm wheel; The outside of said flexbile gear is provided with outer end cap; Be provided with angular contact bearing between said input shaft and outer end cap.
Preferably, said angular contact bearing is provided with a pair of.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The harmonic wave speed reducing machine of tape input axle of the present invention; Optimized its whole structure; Make it compact more, not only reduced the harmonic wave speed reducing machine volume, reduced raw making materials when having reduced space hold; But also make output stable more, accurate, increased the stability and the accuracy of harmonic wave speed reducing machine work; Adopt the criss-crossing roller bearing between flexbile gear and firm wheel, strengthened the rigidity and the intensity of harmonic wave speed reducing machine.
