Design of polymer coating sprayer
Meluzín, Ondřej ; Repka, Martin (referee) ; Šperka, Petr (advisor)
This master’s thesis is aimed on design of polymer coating machine that sprays polymer sliding coatings onto surfaces of crankshaft journal bearings used in car engines. At the beginning of this master’s thesis, basic overview of crankshaft bearings design and materials that are used for sliding coatings is given. Then suitable manufacturing technologies for different materials of coatings are described. After describing basic principles of coating technologies and how crankshaft bearings work, main components used for design of the spraying machine are introduced. Three prototypes of the machine are created in virtual environment to verify ergonomics of control and to fulfill safety requirements. In main part of the thesis, description of all parts and subassemblies, such as frame, spraying circuit, pneumatic regulators and safety features is given. Also functions of all parts of the machine are explained in details. Moreover system for handling and manipulation with coated bearings during all necessary technological operations was created. In addition functionality of the machine was verified and checked by spraying of polymer coating on testing samples and crankshaft bearings.
