[Abstract]:CHC reducer with small tooth difference is a new type gear transmission device, which has many characteristics, such as high transmission ratio, large bearing capacity, compact structure, light weight, high transmission efficiency and so on. It can be widely used in petroleum, chemical industry, hoisting and transportation, construction machinery, etc. Port ships and other major industrial areas. At present, there is no national standard for the design and calculation of CHC reducer with small tooth difference. Due to the lack of reliable basis for design and calculation, the parameter selection of the parts related to the transmission with less tooth difference is unreasonable and the power is rich. In addition, CHC type reducer with less teeth difference is a series of products. Different product specifications have high structural similarity, and their design is repeatable. The main purpose of this paper is to establish a reasonable dynamic model of small tooth difference transmission and to carry on the related force analysis. On this basis, the design and calculation method of small tooth difference transmission is put forward, and the automatic drawing of parts drawing and assembly drawing is realized by reasonable use of existing development technology. The CAD system of CHC type low tooth differential reducer is developed to meet the requirements of product serialization. On the basis of establishing the dynamic model of small tooth difference transmission, taking the design of small tooth difference transmission and key parts as an example, the design and calculation module of CAD is developed by VB programming. Each design process is programmed by using the method of computer aided design. The part information database is established by the operation of the database provided by VB and the design result is saved. The parameterized drawing system uses VB programming technology to realize parameterized drawing from the system object of external operation of AutoCAD by using VB programming technology, under the use of the bottom function of development, the parametric drawing system uses VB text file reading and writing operation to generate detailed design and calculation instructions, and the parametric drawing system realizes parameterized drawing by using VB programming technology. Read the parameters in the part information database and carry out the automatic drawing of the part drawing. The automatic drawing of assembly drawing is realized under the ObjectDBX technology and the extended dictionary of object, and the design data information is transferred from the design calculation part to the parametric drawing part through the part information base. According to the file execution order, the program interface is called to connect each part effectively, and finally the integration of design calculation and parameterized drawing is realized.
