Production of gear wheels with using dividing head
Cicha, Tereza ; Slaný, Martin (referee) ; Jaroš, Aleš (advisor)
The aim of this work is to characterize the production of gear wheels with using dividing head and also to produce the gear wheel by this method. The theoretical part of the bachelor thesis contains an overview of the machining methods for the production of gears and their characteristics. Theoretical chapters also contain a detailed description of the the production of gear wheels with using dividing head and materials used for the production of single gear tooth cutters. The aim of the practical part is to design, calculate and produce the gear wheel with using dividing head. The conclusion of the thesis is the overall summary and evaluation of the calculated data.

Drop forging of gear wheel
Bezděk, Pavel ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
Objective of this bachelor thesis is design of forging of gear manufactured by die forging. Material of gear is steel 12. According to number of forgings per year, forging of gear will be done on vertical forging press LMZ 2500 with nominal forming power of 25 MN. Dies are made of middle doped steel 19 552. In conclusion, costs of producing of gear forging with selected manufacturing technology are evaluated.

Mechanical press 12 500 kN
Buyalskiy, Alexandr ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
This diploma thesis deals with the design of a mechanical press drive. It is a crank press with 4 points. The machine is designed for surface forming of body parts in the automotive industry. The mechanical press can work both in the mode of individual strokes and in automatic operation with the equipment to the production line. The first part deals with an analysis of forming machines and a description of the main parts of the press. The second part deals with the design of the drive based on the specified parameters. This part includes a calculation of the individual sectors of the press and a strength check of the drive parts. The drawing documentation is included.

Forging gear
Šíma, Vojtěch ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated in a frame of Bachelor‘s studies branch B-STG presents a technology design of a forged piece – gear wheel by drop forging. The wheel is made form 12 050.0 material and is a part of an agriculture machine. Considering the series of 45 000 pieces per a year and the precision of production, the drop forging for three operations was selected for production. The wheel will be produced on the crank drawing inclinable press LKZ 1600 P from Šmeral Brno, a.s. producer with nominal tensile force 16 MN. Swages are made of alloyed instrumental steel 19 552.8. At the end of the project technical economic evaluation of production and comparison of the forging technology and machining technology was implemented.

Production of gear wheel
Tesař, Michal ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The work deals with the design of gear production technology and the required production series is 80,000 pieces per year. After evaluating various variants of gear production, the method of fine blanking with a vee-shaped was chosen, on which the literature search is also focused. The part will be made of material E 295 with a thickness of 2 mm and the semi-finished product is a coil of sheet metal. Part of the work is also the design of a tool, which is based on technological and control calculations. A three-acting press from the company Šmeral Brno FMB 440 was chosen as the machine. At the end of the work, an economic evaluation was performed.

Drop forging of gear wheel
Bradáč, Tomáš ; Kopřiva, Miloslav (referee) ; Štroner, Marek (advisor)
This master´s thesis submit a project of technology of production of gear wheel the way of drop forging. A part is made of steel 14 220.0 (16MnCr5). A semi-product is a stick of parametres o75 - 211 ČSN EN 10060, with a production of 130 000 pieces a year. Technological process of drop forging are worked up based on a study presented in technical literature. A forging will be working up on a vertical forging press LMZ 1600 A made in Šmeral Brno, Inc. For this option, the required technological calculation, drawing documentation and forming process simulation which is implemented by way of the software FormFEM have been carried out. Technical and economical evaluation of the component technology producing is brought in as a conclusion of the thesis.

Drop forging of gear wheel
Veselý, Milan ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The project elaborated in a frame of Bachelor’s studies branch B-STG presents a technology design of a forged piece – gear wheel – a part of a gear box made by drop forging from 14 223.0 (20CrMn5-4) material. Drop forging in two operations was suggested on the basis of specialized studies on the subject of drop forging and calculations. Assumed series of 100 000 pieces a year, preciseness and automatization of production of the part, will be produced on the crank drawing inclinable press LMZ 2500 (producer Šmeral Brno, a.s.) with nominal tensile force 25 MN. Swages are made of alloyed instrumental steel 19 552.8, heatworked according to drawing documentation. At the end of the project technical economic evaluation of the technology design is implemented.

Drop forging of gear wheel
Bednařík, Petr ; Lidmila, Zdeněk (referee) ; Štroner, Marek (advisor)
The project elaborated design of technology production of gear wheel from circular blanks of steel 12 050. Pursuant to of the literary pursuit a problem of the die forging and calculation was designed manufacturing process. Dies proposal will be based on relevant standards, materials die steel will be 19 552. Given the complexity of the shape and dimensions of the gear will be used in three operations. Based on the calculated forging force was chosen vertical forging sheet LMZ 1600 A/S with a nominal power of 16 MN. Due to the use of the press die is provided with an ejector.
