Gears, Chains, and Sprockets - VEX Robotics

Create PhaseOverviewThis phase describes the creation and editing of spur, bevel, and worm gear sets. Autodesk Inventor’sDesign Accelerator application contains a specific gear generator for each type of gear.Gears are components that determine the speed, torque, and direction of power as it is transferredthrough a system. Properly designed gears transmit power smoothly and efficiently, thus reducingwear and impact on the system. By changing gear ratios, you can run machinery at optimum efficiencyand adjust to changing conditions. Using Design Accelerator, you can identify multiple gearcombinations, and validate their capabilities within your design.Protobot GearsThe Protobot uses spur gears to drive the wheels and the arm as shown.ObjectivesAfter completing this phase, you will be able to:■■■■Describe gear generation in Design Accelerator.Describe options for spur, bevel, and worm gear generation.Use Design Accelerator to create spur gears.Animate a gear assembly.PrerequisitesBefore starting this phase, you must have:■■■A working knowledge of the Windows operating system.Completed Unit 1: Introduction to VEX and Robotics > Getting Started with Autodesk Inventor.Completed Unit 2: Introduction to Autodesk Inventor > Quick Start for Autodesk Inventor.Create Phase■19
