Abstract
The invention relates to the field of harmonic reducers, and particularly relates to a manufacturing process of an elastic flexible gear. The manufacturing process comprises the following steps: (1) manufacturing a blank and rolling the blank to break the crystal boundary tissues in the flexible gear; (2) carrying out forging and thermal treatment on the rolled parts and adjusting the internal tissue structure of the flexible gear to ensure that the internal tissues of the flexible gear gradually become uniform and gradually obtain a relatively good hardness; (3) carrying out rough machining on the parts; (4) carrying thermal treatment on the parts again to ensure that the internal tissues of the parts are uniformly refined; (5) carrying out finish machining on the parts; (6) carrying surface treatment on the parts. By using the scheme, the flexible gear has a longer service life.
Description
Technical field
The present invention relates to harmonic speed reducer field, refer in particular to the manufacture craft of elasticity flexbile gear.
Background technology
Harmonic speed reducer forms primarily of three basic building blocks: with the rigid gear (just taking turns) of ring gear; With flexible gear (flexbile gear) and the wave producer of external toothing.
As decelerator 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.
The quality of flexbile gear performance directly affects the performance of whole harmonic speed reducer, and one of them very important index is exactly the service life of flexbile gear, and therefore, the present inventor makes further research this, and develop a kind of manufacture craft of elasticity flexbile gear, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of manufacture craft of elasticity flexbile gear, make flexbile gear have longer service life.
To achieve these goals, technical scheme of the present invention is as follows:
The manufacture craft of elasticity flexbile gear, comprises the steps:
(1) manufacture blank, then blank is rolled, smash the crystal boundary structure of flexbile gear inside;
(2) forge and heat treatment the part after rolling, the internal organizational structure of adjustment flexbile gear, makes flexbile gear interior tissue level off to homogenising gradually, and obtains good hardness gradually;
(3) roughing is carried out to part;
(4) again part is heat-treated, make the refinement of inside parts even tissue;
(5) fine finishining is carried out to part;
(6) surface treatment is carried out to part.
After adopting such scheme, the present invention compared with prior art, has the following advantages:
Flexbile gear after above-mentioned process, has good elasticity, and piece surface state is also fine, finally shows as higher fatigue strength and longer service life.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further illustrated.
The manufacture craft of a kind of elasticity flexbile gear that the present invention discloses, comprises the steps:
(1) manufacture blank, then blank is rolled, smash the crystal boundary structure of flexbile gear inside, make it homogenising, improve toughness and the intensity of part;
(2) part after rolling is forged and heat treatment, the internal organizational structure of adjustment flexbile gear, flexbile gear interior tissue is made to level off to homogenising gradually, and obtain good hardness gradually, this operation to improve the toughness of flexbile gear and fatigue strength extremely important, be also make the very crucial operation of of elasticity flexbile gear;
(3) roughing is carried out to part, get rid of the surplus that part is unnecessary;
(4) again part is heat-treated, make the refinement of inside parts even tissue;
(5) fine finishining is carried out to part and surface treatment is carried out to part.
Flexbile gear after above-mentioned process, has good elasticity, and piece surface state is also fine, finally shows as higher fatigue strength and longer service life.
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.
