Research and Development of CAD System for Cycloidal Pinwheel Planetary Reducer (Department of Mechanical Engineering, Huaihai Institute of Technology, Lianyungang 222005, China) Wang Bing's parametric design and assembly design and analysis of cycloidal pinion planetary reducer, reaching design calculation and product model Seamless combination.
1 Cycloidal pinwheel planetary reducer CAD system overall function The design of the cycloidal pinion planetary reducer CAD system is suitable for single-stage deceleration double-axis horizontal BW cycloidal pinwheel planetary reducer. It is designed in accordance with the national machinery industry recommended standard JB/T2982-94. It inputs the original design data, including input power, drive shaft parameters, gear ratio and other empirical coefficients, as well as the operating factor of the reducer and lubrication. The situation, and the material selection of its main components, after the selection and input of the main parameters are completed, the design, check, design calculation manual management, parametric modeling and drawing, assembly simulation of the cycloidal pinion planetary reducer can be realized. , motion simulation and other functions.
1.1 System main interface After starting the cycloidal pinwheel planetary reducer CAD design system, first enter the system welcome interface, the welcome interface flashes for a few seconds, then enter the main interface of the system, as shown.

Through the function of this button, the design and drawing parts of the product are closely combined. If all the parameters are known and not designed, you can fill in the parameters directly in the corresponding text box without clicking this button, as long as the parameters meet the modeling requirements, thus the parameters are implemented. The independence of modeling modeling.
All the parameters are arranged in a certain order, and a data file is generated. 1 When the parameters are passed to WtHeER, all the parameters are transmitted in the form of a file, which saves the trouble of a large number of parameter transmissions and effectively maintains the parameters. Security to avoid loss of parameters during the transfer process. At the same time as the data file is generated, the program will automatically detect the validity of these parameters for the part modeling, otherwise it will give an error message. Of course, these tests cannot include all aspects, and there may be omissions, and data files that do not meet the requirements are generated. Therefore, when the part model fails to be established, the rationality of the parameters should be carefully checked, and the data should be regenerated after modification. File, remodeling. This file is decisive for the generation of the part model. Without it or incorrect parameters, a part model that meets the requirements will not be generated.
It is to start the Pro/E program and build a 3D model of the product. After the product model is successfully generated, the user has to do some related operations: 1 Save the model in the current directory to create an assembly drawing of the product. 2 All operations and analysis work needs to be done before exiting the drawing interface of the part, because the Pro/E program that builds the model will be automatically closed as the interface exits; otherwise, if operation or analysis is still required, Exit the interface.
(4) "Exit" button This button has two main functions: exit the drawing interface of the part, return to the main interface of the cycloidal pin design, but will not exit the cycloidal pin wheel design or system. 2 In order to save memory, the program will also close the Pro/E program that creates the model while exiting the part drawing interface; otherwise, when other part models are built, there will be insufficient memory or Pro/E program startup. The consequences of slow operation make the model fail to build.
Parameter S1330mm Parameter S2 After all the models of the main part are built, you can click on the “Assembly of the Reducer†in the main interface of the design main interface. This is the system automatically opens the assembly model, due to the full data correlation of Po/ENGINEER. The change in part size can be automatically updated in the assembly, making it easy to modify assembly parts.
2.3 Other Interfaces The explosion view of the assembly vividly and visually shows that the assembly of the assembly parts passes through the assembly, and the explosion diagram of the assembly can be automatically generated. In the case of the situation, and after the explosion map is generated, the explosion diagram of the assembly can also be assembled under Pro/ENGIEER as shown in Fig. 12: miejdEleetronie Publishin automatically recovers the assembly situation. Resd precision. The larger the heart S gas, S'., the worse the processing quality of the convex profile surface. The error analysis program block diagram is as follows.
Table 2 The arc surface indexing convex contour surface detection value 2 3 Example In this paper, a groove indexing cam 2 profile with a groove positioning and improved sinusoidal motion law is detected. The mechanism parameters are: center distance 83mm, roller number 6, roller diameter 20mm, roller width Kmm, indexing plate diameter 8丨, cam cam width 72mm, stroke angle 丨20°, cam right hand. In the table, the moving angle is equal to 60. The first column in the table is the measuring point, the second column is the cam angle, the third column is the measuring pendulum angular displacement, the fourth column is the theoretical pendulum angular displacement, the fifth column. The indexing error caused by the cam turning a convex profile at a certain position. Due to space limitations, measurement data is not fully listed. Calculate the error mean and limit deviation U gas = 0.0丨742., SA, =0.0H683, from the measured data.
