Comparison of production possibilities gears plastic and metal

This project is focused on comparison technologies of making cogwheels from plastic and metal. Inside are described principles, descriptions of technologies and appropriate usage or advantages and disadvantages. Mentioned technologies of making metal gears are primarily machining for example milling, slotting or grinding. Making of plastic gears is primarily focused on injection moulding. Practical part of this thesis is focused on exchange metal cogwheel with plastic cogwheel with helping calculations and information from resources. Exchanged cogwheel is from motorcycle ČZ 175/453
