Abstract
The invention provides a flexible gear. The flexible gear is characterized in that a cylinder body (1) has a corrugated structure. The structure can compensate the deviation between an axis of the flexible gear and an axis of an external structure, reduce the internal stress of the flexible gear and improve the transmission performance.
Description
Technical field
The present invention relates to the flexbile gear in harmonic drive, particularly a kind of cylindrical shell has the flexbile gear of ripple struction.
Background technology
Technology of Harmonic Wave Transmission is the development along with space science, aerospace flight technology in twentieth century mid-term, in elastic thin shell theoretical foundationA kind of Novel transmission technology occurring. It has that kinematic accuracy is high, gearratio is large, lightweight, volume is little, bearing capacity is large,And can be under the operating mode of confined space and working medium radiation the advantage such as normal work, be successfully applied to space technology, instrument and meter,In the fields such as robot, printing machinery and medicine equipment.
Flexbile gear, firm wheel, wave producer are called as harmonic drive three-major-items. Wherein the structure of flexbile gear have cup-shaped, annular, bell,The cup end form such as shape and disc of turning up. Wherein cup-shape flexspline, ring-shape flexspline and the cup end turn up shape flexbile gear primary structure respectivelyAs shown in Fig. 1 (a), Fig. 1 (b) and Fig. 1 (c), wherein, flexbile gear cylindrical shell 1 is cylindrical shell.
The present invention proposes based on following factor:
In the time of flexbile gear axis and external structure axis disalignment, axis runout will force cylindrical shell 1 to produce axial bending distortion, therebyAdd internal stress inner generation of flexbile gear.
The present invention proposes a kind of cylindrical shell 1 and has the flexbile gear of ripple struction, and ripple struction can allow certain axial displacement and axisDeflection, departing between compensation flexbile gear axis and external structure axis, reduces flexbile gear internal stress, improves harmonic drive performance.
Summary of the invention
The flexbile gear that the object of the invention is to propose a kind of cylindrical shell 1 and have ripple struction, utilizes ripple struction can allow certain axleTo the feature of displacement and axis tilt, departing between compensation flexbile gear axis and external structure axis, reduces flexbile gear internal stress,Improve harmonic drive performance.
The present invention is by the following technical solutions:
Part cylindrical shell on flexbile gear cylindrical shell 1 adopts ripple struction, the two ends of ripple struction respectively with the cylinder of flexbile gear cylindrical shell 1The smooth connection of housing.
Invention beneficial effect:
The cylindrical shell 1 that the present invention proposes has the flexbile gear of ripple struction, because ripple struction can allow certain axial deformation and axleLine deflection, therefore, is all the flexbile gear of cylindrical shell with respect to cylindrical shell 1, and ripple struction can compensate flexbile gear axis and outside knotDeparting between structure axis, reduces flexbile gear internal stress, improves harmonic drive performance.
Brief description of the drawings
Fig. 1 is flexbile gear primary structure. In figure, (a) being cup-shape flexspline, is (b) ring-shape flexspline, is (c) at cup the endTurn over shape flexbile gear. Wherein, 1-cylindrical shell, at the bottom of 2-cup, 3-ring flange.
Fig. 2 is ripple struction. Wherein, C-waveform, P-crest, R-trough, t-wall thickness, the left side of A-ripple struction,The right side of B-ripple struction.
Fig. 3 is the flexbile gear that cylindrical shell 1 has ripple struction. In figure, (a) being cup-shape flexspline, is (b) ring-shape flexspline, (c)For the shape flexbile gear that turns up at the bottom of cup. Wherein, 1-cylindrical shell, at the bottom of 2-cup, 3-ring flange.
Detailed description of the invention
As shown in Figure 2, wherein waveform C has crest P and trough R to a kind of ripple struction, waveform C, crest P and trough RRight side B, the wall thickness t of left side A, ripple struction of number, ripple struction according to the design that needs of harmonic drive. Require rippleThe left side A of line structure and the right side B of ripple struction respectively with smooth connection of cylindrical shell of flexbile gear cylindrical shell 1.
Fig. 3 (a), Fig. 3 (b), Fig. 3 (c) are respectively cylindrical shell 1 and have cup-shape flexspline, ring-shape flexspline, the cup of ripple structionThe end shape flexbile gear structure of turning up. The left side A of ripple struction and the right side B of ripple struction respectively in i-i cross section, ii-ii cross section and softThe smooth connection of cylindrical shell of wheel cylindrical shell 1.
Ripple struction can be manufactured with other structures on flexbile gear on same blank.
Other structures on ripple struction and flexbile gear can be distinguished manufacture separately, and then adopting the techniques such as welding or bonding to connect is oneIndividual part, this can enhance productivity, and reduces costs.
For bell-shape flexspline, also can on flexbile gear cylindrical shell, adopt ripple struction.
