  • Gear Rolling for Production of High Gears Alireza Khodaee
    Gear Rolling for Production of High Gears Alireza Khodaee Gear Rolling for Production of High Gears Alireza Khodaee Licentiate Thesis, 2015 KTH Royal Institute of Technology Industrial Engineering and Management Department of Production Engineering SE-100 44 Stockholm, Sweden TRITA-IIP-15-06 ISSN: 1650-1888 ISBN: 978-91-7595-678-7 Abstract Gears are used to transmit mechanical work from one point to another. They are widely used in different mechanisms and they are the most important components of a transmission system. Thus, it is important that they are manufactured with high precision to deliver the work with highest possible efficiency. The dominant gear production method is metal cutting, like hobbing. The gear manufacturing industry aims to replace their traditional production lines with greener processes and thereby urge engineers to think about using metal forming methods instead of the traditional metal cutting solutions when possible. Gear rolling is an interesting metal forming method that can be an alternative method to fabricate gear wheels. Research on gear rolling firstly came into interest around 2000. Very few papers are published that covers the development of the method and its limitations and advantages. Almost all of these publications considered rolling of gear wheels with small modules. The focus of this study will be on application of gear rolling for gear wheels with large module (over 3 mm) where the amount of deformation is much larger than found in previous studies. In this thesis the Finite Element Method has been used to simulate and predict the results of rolling of high gears. In addition to that experiments were performed to validate the numerical results and develop the modelling technique for further investigations.

  • General Applications of Gears
    UNIT - III GEAR MANUFACTURING PROCESS SPRX1008 – PRODUCTION TECHNOLOGY - II Gears are widely used in various mechanisms and devices to transmit power and motion positively (without slip) between parallel, intersecting (axis) and non-intersecting non parallel shafts, •without change in the direction of rotation •with change in the direction of rotation •without change of speed (of rotation) •with change in speed at any desired ratio Often some gearing system (rack – and – pinion) is also used to transform Rotary motion into linear motion and vice-versa. Fig.1 Features of Spur Gear Gears are basically wheels having, on its periphery, equispaced teeth which are so designed that those wheels transmit, without slip, rotary motion smoothly and uniformly with minimum friction and wear at the mating tooth – profiles. To achieve those favorable conditions, most of the gears have their tooth form based on in volute curve, which can simply be defined as Locus of a point on a straight line which is rolled on the periphery of a circle or Locus of the end point of a stretched string while its unwinding over a cylinder as indicated in Fig. General Applications of Gears Gears of various type, size and material are widely used in several machines and systems requiring positive and stepped drive. The major applications are: • Speed gear box, feed gear box and some other kinematic units of machine tools • Speed drives in textile, jute and similar machineries • Gear boxes of automobiles • Speed and / or feed drives of several metal forming machines • Machineries for mining, tea processing etc. • Large and heavy duty gear boxes used in cement industries, sugar industries, cranes, conveyors etc.

  • Experimental Simulation of Gear Hobbing Through a Face Milling Concept in CNC-Machine
    Experimental simulation of gear hobbing through a face milling concept in CNC-machine SABA HOSEINI Degree project in Second cycle Stockholm, Sweden 2013 www.kth.se Powered by TCPDF (www.tcpdf.org) Experimental simulation of gear hobbing through a face milling concept in CNC-machine Author: Saba Hoseini Report No.: Kimab-2013-119 Swerea KIMAB Project No.: 265010 Date: 07.08.2013 Member program: MRC Materials in Machining i Abstract High-speed steels are the main material for cutting tools especially for producing gear boxes in the automotive industry. Cutting performance of high speed steel depends on their resistance to wear, their toughness and resistance to tempering at operating temperature. In this project, tool-life and wear type of cutting tools made of powder metallurgy high speed steel (PM-HSS) were investigated up to a flank wear width of 0.30 mm in different steels and cutting speeds. Hardness and cutting speed had a significant effect on tool-wear, tool-life and chip formation. More rake face wear was occurred by harder materials because of higher thermo- mechanical loading .Three indicators were used for representing tool life and to show the relation of cutting speed and hardness with cutting performance. Difference of tool life between the softest and the hardest steels was about two times. By increasing cutting speed in every work-material more number of passes was obtained. The required data were obtained experimentally by a 3-axis milling machine. This test method facilitates simulation of gear hobbing wear type in a less time-consuming way, compared to the other methods which have the same kinematics of real hobbing.

  • VIRTUAL HOBBING E. BERGSETH Department of Machine Design, KTH, Stockholm, Sweden SUMMARY Hobbing Is a Widely Used Machining Proc
    VIRTUAL HOBBING E. BERGSETH Department of Machine Design, KTH, Stockholm, Sweden SUMMARY Hobbing is a widely used machining process to generate high precision external spur and helical gears. The life of the hob is determined by wear and other surface damage. In this report, a CAD approach is used to simulate the machining process of a gear tooth slot. Incremental removal of material is achieved by identifying contact lines. The paper presents an example of spur gear generation by means of an unworn and a worn hob. The two CAD-generated gear surfaces are compared and showed form deviations. Keywords: gear machining, CAD, simulation 1 INTRODUCTION analysis of the tolerances applied to gears, each step in the manufacturing process must be optimized. Better The quality and cost of high precision gears are aspects understanding of the geometrical variations would which are constantly of interest. Demands stemming facilitate tolerance decisions, and make it easier to from increasing environmental awareness, such as meet new demands. lower noise and improved gear efficiency, are added to traditional demands to create (MackAldener [1]) a Gear manufacturing consists of several operations; challenging task for both manufacturers and designers. table 1 shows an example of a gear manufacturing To be able to adjust to these demands, a design must be sequence for high precision external spur or helical robust; that is, it must deliver the target performance gears. regardless of any uncontrollable variations, for example manufacturing variations. Manufacturing variations can include geometrical variations caused by imperfections in the manufacturing process, for example, wear of tools. The geometrical deviations of each part must be limited by tolerances in order to ensure that the functional requirements are met.
