By using reliable and efficient computer based tools it is possible to replace initial physical testing. This will result in cost savings, but it will also reduce the development time and material waste, since the demand of physical prototypes decreases. This thesis shows how a computer program for analyzing contact mechanics in spur and helical gears has been developed at the request of Vicura AB.

    - - IJRDO - Journal of Computer Science and Engineering ISSN: 2456-1843 JOURNAL OF MECHANICAL AND CIVIL ENGINEERING GEARS Shivam Bansal Mechanical Department Dronacharya College of Engineering Khentawas, Farukhnagar,Gurgaon [email protected] Yogesh Vashiath Mechanical Department Dronacharya College of Engineering Khentawas, Farukhnagar,Gurgaon [email protected] Ujjwal Batra Mechanical Department Dronacharya College of Engineering Khentawas, Farukhnagar,Gurgaon [email protected] INTRODUCTION A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in tandem are called a transmission and can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a non-rotating toothed part, called a rack, thereby producing translation instead of rotation. The gears in a transmission are analogous to the wheels in a crossed belt pulley system. An advantage of gears is that the teeth of a gear prevent slippage. When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with the rotational speeds and the torques of the two gears differing in an inverse relationship. In transmissions which offer multiple gear ratios, such as bicycles, motorcycles, and cars, the term gear, as in first gear, refers to a gear ratio rather than an actual physical gear.

  • 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.

It directly effects the vehicle performance, drivers comfort and fuel economy .The comparison between all types of transmission system, the gear shifting strategy in transmission systems and power transmitting drives are explained. Keywords: Clutch, Sequential Gearbox, CVT, Differential & Its Types, Power Transmitting Drives, CV Shafts _______________________________________________________________________________________________________ I. INTRODUCTION Transmission System is the next and final stage of the engine generated power before it hits the wheels. The whole system is responsible to connect engine and wheels, driving and alter the output shaft rotation to a desired speed/torque ratio, allowing a wide range of speed and better performance as the engine has its own RPM limit and maximum torque. Transmission system consists of following major parts. Clutch (Dry/Wet). Gearbox/ CVT. Differential (Open, Torsen). Power transmitting drives (Chain, Belts, Cv shafts). Each part has a specific role in transmitting power from the engine to the wheels ensuring correct rpm and torque.

  • Design, Modelling and Analysis of Herringbone Gear Using Ansys D.Ramakrishna [1], Ch.V.S.Paramaeswararao [2], S
    International Journal of Engineering Trends and Applications (IJETA) – Volume 3 Issue 4, Jul-Aug 2016 RESEARCH ARTICLE OPEN ACCESS Design, Modelling and Analysis of Herringbone Gear Using Ansys D.Ramakrishna [1], Ch.V.S.ParamaeswaraRao [2], S. Siva Naga MalleswarRao [3] M.Tech Research Scholar [1], Professor [2] & [3] Department of Mechanical Engineering PBR VITS, Kavali-524201 India ABSTRACT Herringbone gears, also called as double helical gears are the gear sets designed to transmit power through either parallel or less commonly perpendicular axes. The unique tooth structure of a herringbone gear consists of two adjoining opposite helixes that appear in the shape of the letter 'V'. Herringbone gears usually mate via the use of smooth, precisely manufactured V-shaped teeth. Like helical gears multiple teeth are engaged during rotation, distributing the work load and offering a quiet operation. However, due to their tooth structure, herringbone gears nullify the axial thrust unlike helical gears. The gear set's teeth may be manufactured so that tooth-tip aligns with the opposite tooth-tip or the opposite gear's tooth trough. In this project, herringbone gears that are used in a rolling mill gear box is designed using a 3D modelling software called Solid works. Static, Modal and Fatigue Analysis has been carried out on herringbone gears using ANSYS tool. Alloy Steel, GRP and Carbon fiber materials have been analysed and studied for comparison. The selection of better material for herringbone gear is determined out of this analysis. This Paper is the result of the analysis carried out by using ANSYS 14.5 on a 3D model of Herringbone gear which was generated using Solid works tool.
