Development of CAD/CAM System for Cylindrical Gear Reducer

The cylindrical gear reducer has the characteristics of high precision, high load, high efficiency, high life, low inertia, low vibration, low noise, beautiful appearance, light and small structure, and easy installation. Independent transmission.The cylindrical gear reducer includes gears, shafts, bearings, bearing ends and other parts.With the continuous improvement of CNC machining machine tool processing technology, the production trend of cylindrical gear reducers is also developing towards automation, precision and networking.At present, the commonly used reducer design work still faces the problems of cumbersome design and heavy workload, and the processing of the main parts of the reducer, gears, shafts, and boxes are mainly processed by ordinary machine tools, and the design and production efficiency are relatively low.

The CAD/CAM system of the cylindrical gear reducer is developed based on the visual programming language, Pro/EngineerWildfire software, and the CNC machining simulation software VERICUT software.Use visual programming language to carry out parametric design, use Pro/E to realize automatic programming of parts and optimize processing parameters, and then use VERICUT software to simulate processing to realize the integration of reducer design, modeling, and numerical control simulation processing and manufacturing. change.The technology improves the design efficiency of the reducer, shortens the design cycle, reduces the design cost, improves the product quality of the cylindrical gear reducer, and improves the competitiveness of the enterprise.

Parametric design module for cylindrical gear reducers.The main parts of the gear reducer, such as gears, shafts, boxes, etc., are parametrically designed using a visual programming language, that is, the calculation formulas, line diagrams, tables, etc. required in the design are programmed, and the design parameters required for the design, And XNUMXD modeling in Pro/E software.Use Pro/E software to build a three-dimensional graphics library of the reducer's accessory breather, screw plug, and oil dipstick, and finally realize the simulated assembly of the cylindrical reducer.
