1=SimSun Abstract introduces the design content of the ring planetary reducer 00 kernel system. Discusses the development method and design principle of the human-system of the ring planetary reducer.
Compared to manual design. Improve design quality and shorten design cycle. Reduced design costs. The reliability of the system is verified by an example. The ring gear reducer with many gear ring reducers is a new type of gear transmission. Compared with the existing main gear transmission forms, it has a simple structure and small volume. The transmission ratio is high, the transmission efficiency is high, the bearing capacity is strong, and the manufacturing cost is low. 3 For the small-tooth difference internal meshing drive, the geometrical calculation of the internal meshing gear pair is to avoid interference, although the use of short-tooth and positive-displacement gears can effectively solve this problem, but it is followed by a decrease in the degree of coincidence. Therefore, the main content of geometric calculation is to choose the parameters reasonably from the consideration of these two aspects. In order to shorten the product development cycle, modern design methods such as finite element analysis and design reliability design are applied to product design, and modeling and analysis simulation interference checking is performed on a computer. It is necessary to develop a small-tooth difference ring reducer. Parts, fairy system.
The design and development of the system with less tooth difference ring reducer 0 has less tooth difference ring reducer. The contents of the system include the calculation and analysis of the material system, the design and manufacture of the manufacturing process parts subsystem. Material system module package materials and parameter selection. The heat treatment method selects the surface treatment method selection; the calculation analysis includes the classical calibration finite element analysis, the calculation of the fatigue life prediction, the shape optimization, the transmission system, the dynamic simulation, the noise prediction, the efficiency, the juice calculation, the prediction, the processing parameter calculation, etc.; the manufacturing process includes the part processing parameters. Select the process size to calculate the processing route reasoning process route ordering; the part subsystem includes the internal gear parameters to calculate the external gear 0 into the 0 subsystem internal ring plate, the set low field (2), the noisy, 0 subsystem bearing into the system cabinet The subsystem is less than a differential ring reducer, and the system is worn by a mechanical input system. It is different from the general machine 0 from the software, and the close relationship is necessary to select + good general mechanical 10 soft æ±´ as the supporting software for secondary development, which should meet the new ideas and new technologies of software development. Wood has to understand the production situation of the gearless reducer, so that it can be used to design a WilkCADCVE;it, CADCAI5; development experience and software engineering design, the system uses object-oriented software development technology in the engineering database On the basis of the development, it is developed into a scoring technique to obtain the knot of the three corners. For the reconstruction of the song 1, usually from the point to the line, from the line to the surface, the main surface is first established, and then the transition surface is established. Building a surface directly from a point or wanting to fit a surface with a surface is usually unsuccessful. The dimensional model of the product is established in Shenzhong. For the data measured by the coordinate measuring machine, the conversion interface of the measurement data file to the sink software is compiled by using the 0 language, 7 and enters the software for reverse seeking. For data processing, compensation must be made due to the fixed diameter of the probe. The method adopted by our school is to first establish the secondary 8 spline curve of the measuring point, then equidistantly offset the 8 spline curve, obtain the strip equidistant 8 spline curve, and then define the equidistant 8 spline curve. Extract it and use the defined points to fit the line and arc. Using the 0 calendar, the language has compiled the fitting program of the line and the arc. Other feature parts are usually obtained by the ordinary method according to the design rules, and can be obtained by feature modeling, and finally the shape of the product is obtained.
Conclusion With the shortening of the current product development cycle, the reverse engineering technology based on physical design is an organic supplement to the dimensional design system. Practice has proved that reverse engineering can be digested and absorbed through prototypes, modified and redesigned to accelerate product innovation.

The mechanical craftsman is now modern in the manufacture of internal gear ring plate type eccentric shaft type output shaft type feature geometry library standard parts library material library support for the body parameterized, Sha, human system, while insisting on parameterization goals in the development process The principle of combining characterization and standardization and the combination of program and program 3. The structure of the reducer 10 system After the system is activated, it first enters the selection of the reduction and the structure of the device.
Determine the main parameters of the transmission, and then transfer the parts of the external gear internal gear ring plate eccentric shaft output shaft bearing that meet the parameters and structural scheme from each subsystem, and transfer the required standard parts from the standard parts library to set the overall design of the reducer. . After designing the dynamic visit of the entrance hall, the strength analysis of the box is limited. If there is any problem, modify it until the design obtains satisfactory results, then carry out detailed design and finally generate the project. When the engineering sample is generated, the system automatically completes the selection of the interface to complete the standard or has been completed automatically or in a human-computer interaction manner. 1 is the reducer ç›1. From the system structure frame, in the 1 small tooth difference internal meshing drive, the determination of the displacement coefficient is the design connection relationship, so the iteration of the displacement coefficient is derived by the calculation formula of different gear processing methods. Formula, the resulting iterative results are not the same as the most widely used planetary gears and spur gears. Most of the external gears are cut on a hobbing machine with a spiral gear hob. The internal gear is usually formed by inserting a toothed cutter into the gear shaping machine. In the internal gear parameter calculation module, the calculation iteration formula of the displacement coefficient under various actual machining conditions with small tooth difference internal meshing transmission has been deduced, and the man-machine dialogue mode is selected in the calculation.
Whether to calculate the gear becomes an example, the introduction of the 00 person subsystem adopts a small difference loop type reducer, 0, system to set the optimization of the ring part and the system. Through the dynamic simulation of fatigue life prediction of transmission system, the most suitable gear parameters and structural dimensions of the parts are selected to minimize the manufacturing cost and the weight of the gearbox, shorten the development and test cycle, and improve the product quality.
Internal meshing, wheel parameter calculation and internal tooth ring plate, 1 subsystem selection internal and external gear machining method tool parameter library select machining tool parameters input initial parameter gear modulus, number of teeth, pressure angle tooth height coefficient, tooth tip clearance coefficient coincidence degree. Tooth profile does not overlap, coefficient initial selection gear displacement coefficient iterative calculation gear displacement coefficient output gear displacement coefficient coincidence degree in the iterative calculation process of the displacement coefficient, the iteration value of the gear displacement coefficient will affect the actual center distance value Considering the actual conditions of factory processing. For the actual hatred to carry out two-digit design of the internal gear parameters, the gear modulus is book = the number of external gear teeth!
The tooth top height coefficient = 1.25, the displacement coefficient edge = 42. Take the coincidence degree = 1. The tooth profile interference coefficient 0 results in = 1.37, 12 = 1.685, rounded center distance! = Set the interference coefficient of the corridor = 0.05047.1. The inner and outer wheels are all inserted with a knife. The iterative result is = 1.23 = 1.528. Round center distance, = 2.4, meshing angle = 38.456, actual coincidence degree to the internal tooth ring plate, subsystem. The purpose of the first is to say that the geometry of the wheel is based on the parametric design of the artificial joint taken by the 0 coffee 4 and the quality of the Song Ping meter. Has good interactivity; a wide range of 0 female support software. Its powerful and powerful, but.
For a specific product, only by means of secondary development can it improve its design efficiency and design quality. Among the various development tools provided by People 7, the 0,++ development tools are the most efficient and powerful.
The artificial joint design needs to first construct a dimensional entity model based on the patient's damaged joints and pieces, and construct a dimensional plane model from the solid model, that is, the sample that meets the processing requirements. The data transferred from the dimension model to the dimension model is the entity parameter data, which can also be input from the dialog box. The process is the parameter + data 20 model production model, which divides the geometric model of the gear part into the overall shape voxel of the ring plate, the internal tooth processing voxel, the auxiliary processing voxel, the auxiliary function voxel, and the voxels are Boolean The geometric model of the gear is obtained. Then, the bending strength of the gear is limited, and the life of the contact is limited. The network is automatically split to realize the finite element mesh part of the gear and the tooth profile. Then the finite element analysis technology is used to make the gear more precise and dynamic. Mechanical analysis, check, strength, analysis. The technique of the shirt analyzes the geometry of the tooth profile and predicts the coincidence of the gears. After analysis and modification, the shape and parameters of the gear are finally determined, the machining parameters of the gear are calculated, the parts of the gear are generated, and the data is transferred to the shape database.
Conclusion The mining and planetary reducer and the chemical system are designed to design the ring-type hall speed reducer, which can conveniently realize the optimization of the whole-time plan and the optimization of the component structure, and accurately determine the processing parameters of the ring gear and the pinion gear. Accurate analysis and calculation of each component can improve product design quality and product reliability. The use of advanced development methods and modern design methods and adherence to the development principles of targeted parametric characterization and standardization and development of the ring planetary reducer, the æ°š 0 system is practical and reliable.
