[Abstract]:Planetary gear transmission has the advantages of large transmission ratio, compact structure, small volume and mass, high efficiency, low noise and smooth operation. It is widely used in lifting, mining, construction machinery, ship, aviation, etc.As well as the national defense industry and other departments as deceleration, speed change or speed gear transmission.In order to improve the design efficiency, reduce the design errors and meet the needs of CAD/CAE/CAM integration, the research on the planetary transmission device is of great practical significance in modularization, serialization and parameterization design.The 3D software SolidWorks is redeveloped with the object-oriented development tool VisualBasic6.0, and the design parameters, design results and model parameters are managed by the relational database management software Microsoft Access.The NGW planetary reducer structure design calculation and strength check, the key parts serialization, parameterized modeling and integrated system are made into the plug-in form of integration with SolidWorks.The following tasks have been completed:1. Based on the research of the design theory of NGW involute planetary gear transmission, the design and calculation of NGW type involute planetary gear reducer are realized by using VisualBasic6.0 and Microsoft Access database as development tools.Through the user interactive design process, input power, rotational speed, total transmission ratio, expected life, transmission efficiency and other initial parameters, the system can obtain the recommended transmission series, transmission ratio distribution, etc.Tooth number distribution, gear geometric parameters calculation and strength check results, as well as structural parameters of the parts.2. The parameterized modeling method of the key parts of NGW planetary reducer is studied. The powerful parameterized modeling function of 3D design software SolidWorks and a large number of secondary development interface functions are used.The parameterized modeling of the three-dimensional model of key parts based on feature is realized.Through the parameterization method of dimension driving or the parameterization method of the combination of dimension drive and program drive, the new 3D model designed by the designer can be completed by changing the main parameters of the part and generating the new 3D model designed by the designer.The parameterized model of the assembly parts with fast and accurate positioning is generated, and the kinematics simulation and interference check are carried out to feedback the merits and demerits of the design results in time, which provides reference for improving the design results.3. The second development of SolidWorks is carried out by using the development mode of DLL(Dynamic Link, and the system of planetary reducer design automation is made into the plug-in mode of SolidWorks, which realizes the seamless integration between the system and SolidWorks.To solve the problem that the design results and 3D modeling data are separated from each other.The design automation system of NGW type planetary gear reducer can quickly design the product, reduce the repeated and tedious calculation and modeling work, improve the design efficiency and reliability, and shorten the design period.It can also provide reference for the development of other serialized products.
