Constant Speed Mechanism

grabcad

This project was created using Autodesk Inventor 2014, featuring dynamic simulations in its Inventor Studio module. The animation results from a crank rotation at 240 degrees per second or six rotations per minute. A four-bar mechanism is connected to a curved fork and slider, with the crank rotating three times between angles of 200° and 10° – active movements at either end, and a return movement in between. The clever design of this four-bar system causes the slider to maintain a quasi-constant speed of about 57 mm/s during active movements, as displayed in the "Output Grapher.jpg" image, which graphically represents the velocity of the sphere's center (the indicator). To view this simulation in Inventor, download all files into a single directory and open the .iam file with Inventor 2014 or later versions. Access Environments/Dynamic Simulation and click Play. If you prefer, reduce the number of images rendered from 5000 to 1000 for faster processing, although this may affect resolution. The higher image count ensures a high-quality living clip as a result. Have fun exploring!
