Design of manufacturing technology for plastic cogwheel
Vyhnanovský, Jaroslav ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This project has been developed within the master study of Engineering Technology and Industrial Management a design of manufacturing technology for plastic cogwheel is introduced. The cogwheel will be produced by plastic injection moulding. POM material with a trade name Delrin 100 NC010 from DuPont Company will be used. An injection mould is a tool for producing a plastic cogwheel using injection moulding technology. Production will take place on the machine Allrounder 420 C Golden Edition 1000-290 from Arburg German Company headquartered in Loßburg, where the seat of parent company is situated.

Gear production design
Rusková, Marie ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of a gear, which is located on the rear half-axle of the tractor. Due to the high torque transmission, it will be made of 12 061 steel. After assessing the various production technologies, the forging on the vertical crank press were chosen as the most optimal. Forging was designed according to the standard ČSN 42 9030. The semi-finished product is going to be a rod with a diameter of 125 mm, which will be divided by cutting to a length of 219 mm. Forging will take place in three operations. Based on the highest calculated required force, which came out to 63.16 MN, the LZK 6500 machine was chosen. An LDO 315 A/S trimming press will be used to remove the protrusion and membrane.
