Reciprocating Mechanism for Rotary Wear Testing Machine

grabcad

The Objective of the project is to investigate the pin on disc wear testing machine and to develop a suitable mechanism to convert the continuous rotary motion to reciprocating motion without hindering the original functionality.Steps:1. The Project involved studying the existing machine, developing a concept such that it doesn't hinder the original functionality. 2. It involved developing a suitable concept, Designing the components through Hand calculations, Developing CAD Model in CATIA, Drafting with the Bill of Materials.3. Manufacturing the components with the laboratory equipment and testing with a standard materials.The Calculations involved:1. Calculating the torque on the motor side to prove that it can overcome the resisting torque.2. Calculating the length and cross-section of connecting rod based on stroke length.3. Calculating the height and loads on the structure.4. Calculating the dimensions of the block and plate.5. Selection of appropriate materials for the components.6. Fabrication with operations like shearing, drilling, and MillingManufacturing Processes Involved:1. Drilling - For drilling the various holes and tapping them.2. Shearing - For cutting MS Angle to the appropriate length for the structure.3. Welding - Structure and base plate on the structure.4. Milling - For making the slot in Slider Block5.
