Description
Technical field
The present invention relates to harmonic speed reducer field, refer in particular to a kind of life-span of harmonic speed reducer, efficiency, starting torque pick-up unit.
Background technology
Harmonic speed reducer forms primarily of three basic building blocks: with the firm wheel of ring gear; With flexbile gear and the wave producer of external toothing.
As speed reduction unit use, usually adopt wave producer active (input), just take turns fixing, flexbile gear output form, wave producer is a rod-like members, and its two ends are equipped with rolling bearing and are formed roller, are mutually compressed by flexible bearing with the inwall of flexbile gear.Flexbile gear is the thin-wall gear that can produce larger elastic deformation.Wave producer is the component making flexbile gear produce controlled elasticity distortion, after wave producer loads flexbile gear, the section of flexbile gear is forced to become different in nature curved surface by original circle by flexible bearing, tooth near its major axis two ends engages completely with the tooth of just taking turns, and the tooth near minor axis two ends is then thrown off completely with firm wheel.The transition state that on girth, the tooth of other sections is in engagement and departs from.When wave producer rotates continuously, the distortion of flexbile gear constantly changes, and flexbile gear is also constantly changed with the engagement of just having taken turns, by engaging-in, engage, nibble out, throw off, engaging-in again, carry out again and again, thus realize flexbile gear and relatively just taken turns along the rightabout slow circumvolve of wave producer.
For harmonic speed reducer, its rotating accuracy (error between the theoretical value of input and output ratio of gear and actual value) is the important indicator passing judgment on harmonic speed reducer quality, in present stage, the rotating accuracy device of harmonic speed reducer can only be used for detecting its Static State Index, and its dynamic indicator cannot be detected, therefore, the present inventor makes further research this, develop a kind of life-span of harmonic speed reducer, efficiency, starting torque pick-up unit, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of life-span of harmonic speed reducer, efficiency, starting torque pick-up unit, the life-span of harmonic speed reducer, efficiency, starting torque can be measured.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of life-span of harmonic speed reducer, efficiency, starting torque pick-up unit, comprise torque sensor, actuating unit, load maintainer, harmonic speed reducer comprises input end and output terminal, the input end of harmonic speed reducer and actuating unit are linked, the output terminal of harmonic speed reducer is connected with load maintainer, and input end is all connected with torque sensor with output terminal, be also provided with torductor at pedestal side.
Further, described actuating unit is arranged on adjusting mechanism, and adjusting mechanism can drive actuating unit horizontal slip.
Further, described load maintainer is magnetic powder brake.
After adopting such scheme, the present invention compared with prior art, has the following advantages:
By simulating the operation conditions of harmonic speed reducer, and reading corresponding technical parameter, detecting the life-span of harmonic speed reducer, efficiency, starting torque.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
As shown in the figure, the life-span of a kind of harmonic speed reducer that the present invention discloses, efficiency, starting torque pick-up unit, comprise torque sensor 1, actuating unit 2, load maintainer 3, torductor 4, the firm wheel of harmonic speed reducer is fixed on pedestal, harmonic speed reducer comprises input end (wave producer) and output terminal (flexbile gear), and the input end of harmonic speed reducer and actuating unit 2(motor) link, rotated by driven by motor input end, the output terminal of harmonic speed reducer is connected with load maintainer 3 (simulating harmonic speed reducer in running order), input end and output terminal are also connected with torque sensor 1, described torque sensor 1 is linearly arranged with the input end of harmonic speed reducer.Actuating unit 2 is arranged on adjusting mechanism 5(slide rail or rack rails) on, adjusting mechanism 5 can drive actuating unit 2 horizontal slip.Torductor 4 is arranged on pedestal side and is positioned at by harmonic speed reducer.
The course of work:
First, fixed by harmonic speed reducer, be connected with actuating unit 2 by the input end of angle speed reduction unit with shaft coupling respectively, be connected by the output terminal of harmonic speed reducer with load maintainer 3, particular location is adjusted by adjusting mechanism 5.
After above-mentioned work completes, starter motor, reads the measured value of torque sensor 1 on harmonic speed reducer input end and output terminal respectively, can draw the transmission efficiency of harmonic speed reducer.
In aforesaid operations process, if only need to measure harmonic speed reducer static accuracy, the magnetic powder brake of loading component cuts out, when needs carry out kinetic measurement, start magnetic powder brake, and regulate current value, just can obtain corresponding torque value, reach the object of kinetic measurement.
When after motor rotation, if find that larger change occurs the numerical value on torque sensor, then illustrate that harmonic speed reducer is in damaged condition, arrive the time of now motor rotation, be the life-span of harmonic speed reducer.
Apply a moment of torsion by torductor 4 for harmonic speed reducer, once detect that harmonic speed reducer rotates, then moment of torsion is now just the starting torque of this harmonic speed reducer.
Above are only specific embodiments of the invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
