Presentation Summary : Gear and Gear Terminology By: Gp Cap Dr Hamid Ullah Khan Niazi Objectives After completing this unit you should be able to learn: Identify and state the. is the diameter of the pitch circle. Download gear and terminology PPT for free. ; Diametral pitch P: The number of teeth of a gear per inch of its pitch diameter. TEL : +81 48 254 1744 Fig. "Gear Nomenclature", Pitch Pitch is generally defined as 'the distance between equally spaced points or surfaces .a100g 3 given line or 'curve. Spur gear is used when shafts must rotate in the same plane. Ona cylindrical gear it is the arc length between similar points on J'une-July 1984 31. Gear Ratio : Gear ratio is numbers of teeth of larger gear to smaller gear. is the diameter of a circle around the outer surface, or tops of the gear teeth. SPUR GEAR SPUR GEAR Spur gears or straight-cut gears are the simplest type of gear. This page is a part of KHK's Gear Technical Reference. Gear Types and Terminology is a page to learn types of gears and gear related technical words. The curve most commonly used for gear-tooth profiles is the involute of a circle. Pitch Circle. Other examples of gears are in simdesign/gear10.30.sim and simdesign/gear20.30.sim 7.3.1 Generation of the Involute Curve. Working depth: is the distance that one tooth of a meshing gear penetrates into the tooth space. A toothed gear must have an integral number of teeth. When gear sets are visualized as a pair of smooth contacting Spur Gear Terms and Concepts Description In order to design, build and discuss gear drive systems it is necessary to understand the terminology and concepts associated with gear systems. The teeth are straight and parallel to the shaft. August 15, 2007 54 Gear terminology Clearance (c): is the addendum minus dedendum. Basic Gear Terminology INVOLUTE Face Width is the length of the teeth in the axial direction. If the 15-tooth gear is the driving gear and the 30-teeth gear is the driven gear, their velocity ratio is 2. Winner of the Standing Ovation Award for Best PowerPoint Templates from Presentations Magazine. Figure 7-3 Involute curve. Pressure Angle : Pressure angle is the angle between the pressure line and common tangent to pitch circles. 7.5). The pinion is the smaller of a gear pair. The circular pitch, therefore, equals the pitch circumference divided by the number of teeth.The diametral pitch is, by definition, the number of teeth divided by the pitch diameter. Outside Diameter (O.D.) tooth thickness of one gear and the tooth space of the meshing gear measured along the pitch circle (Fig. Pitch Diameter (P.D.) Gear Terminology: Terms Used in Gears August 25, 2019 by Sundar Dannana Leave a Comment In the Power transmission segment, gears have a significant role in transmitting the torque by the required velocity (transmission ratio) at the driver end to the driven end without any slipping. Presentation Title: Gear And Gear Terminology . Circular pitch p: The width of a tooth and a space, measured on the pitch circle. World's Best PowerPoint Templates - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from. gear and terminology Powerpoint Presentation . Good designers and engineers have experience and knowledge and the ability to communicate their thoughts and ideas clearly with others. 1-6-CirculRr Pitch of gear teeth is the arc: length .along the pitch circle Pressure Line : Pressure line is the common normal at the point of contact of mating gears along which the driving tooth exerts force on the driven tooth. Types of Gears A) Bevel Gear Transmit power at 90o B) The Miter gear C) Angular bevel gears D) Hypoid Gears Gear Terminology Addendum: is the radial distance between the pitch and circle and the outside diameter or height of the tooth above the pitch circle. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect.
