Construction of the laboratory crankshaft mechanism

Ročični mehanizem predstavlja enega izmed temeljnih izumov tehnike. V osnovi pretvarja rotacijsko gibanje v linearno ter obratno. Kljub relativno enostavni zgradbi, ima več kinematsko-dinamskih posebnosti, ki jih je tekom zasnove takega mehanizma potrebno upoštevati. V sklopu naloge smo želeli izdelati preprost ročični mehanizem z uporabo cenovno ugodnih ter dostopnih tehnologij. Za izdelavo smo uporabili tehnologijo 3D tiska. V proučevanju kinematike smo se posvetili obravnavi pospeška linearno gibajočega se dela mehanizma. Zasnovali smo komponente za pogon ter krmiljenje mehanizma in merilno verigo za merjenje časovnega signala pospeška. Izmerjeni pospešek smo nadalje primerjali s teoretično napovedjo.A slider-crank mechanism is one of the technique\u27s most fundamental inventions. It basically converts rotational motion into linear and vice versa. Despite its relatively simple design, it has several kinematic-dynamic features that need to be considered, while designing such mechanism. As a part of this thesis, we aimed to create a simple slider-crank mechanism using low-cost and affordable technologies. We used 3D printing technology for the production. In the study of kinematics, we have devoted ourselves to the treatment of the acceleration of mechanism\u27s linearly moving part. We designed the components for the drive of the mechanism and the measuring system for measuring the time signal of the acceleration. The measured acceleration was additionally compared with the theoretical prediction
