[Abstract]:Based on the meshing theory of harmonic gear transmission and the related knowledge of spline curve, a new type of harmonic transmission tooth shape-尾 tooth type is proposed in this paper. The tooth shape accords with the meshing principle of harmonic drive, can improve the performance of harmonic reducer, and has the characteristic of convenient adjustment. At the same time, based on the conjugate principle, the design software of the 尾 tooth profile of harmonic reducer is completed, and according to the conjugate theory, the involute tooth profile is analyzed and verified by the software. The main contents of this paper are summarized as follows: (1) on the basis of the theory of involute tooth profile and spline curve, the 尾 tooth profile is put forward, that is, according to the specific parameters, the initial tooth profile equation of the flexible wheel is obtained, and then according to the set optimization criterion, The tooth profile curve of flexible wheel is optimized, and the optimized tooth profile is obtained. (2) based on conjugate theory, the curve of rigid wheel conjugate with the tooth shape of flexible wheel is obtained. The curve is in a theoretical conjugate state with the flexo tooth profile. (3) on the basis of the above conjugate curves, the normal distance curve of the rigid wheel curve is calculated to meet the requirements of the actual back gap. (4) the final tooth profile curve can be accurately described by AutoCAD. The static analysis of the model is carried out by using ANSYS software. (5) the stress distribution of harmonic reducer with 尾 tooth is compared with that of double arc and involute gear of the same size by using ANSYS software under the same loading condition. The results show that the performance of 尾 type tooth shape is obviously higher than that of the other two tooth types. (6) on the basis of the above work, a software is developed to draw the curve of 尾 shape tooth profile and conjugate curve of flexible wheel, and the corresponding parameters are input into the software. The software can easily draw the 尾 type tooth profile curve. (7) finally, the involute tooth profile curve of 32-80 type is used as the verification object, and the physical prototype is processed according to the verification results. Through the above work, it is shown that the beta-type tooth type is more advanced than the existing tooth type, more in line with the meshing requirements of harmonic gear transmission, and makes the performance of harmonic reducer more perfect.
