NC gear tooth disc piding training platform design
Abstract: This topic for CNC gear tooth disc piding training platform design. The basic concept of design is accomplished by a secondary reduction gear deceleration, thus make indexing table loosen and tighten the positioning process. The double reduction device using a combination of gear and worm gear and worm; Degree of loosening and tightening using three tooth segmentation for piding the work table; One of the driving device using hydraulic drive. The design in line with the use of large gear ratio for the concept of relative accurately piding work, everything with simple structure, convenient and efficient for the purpose to proceed with the design, and connecting with the domestic and foreign advanced technology concept to complete the overall and local design.
Key Words: NC; ；Teeth plate of piding； ;rotary；Engineering training platform
