all about gears (kinds ,applications,.....)

Gears Gears are Power transmission elements. It is the Gears that decides the torque, speed and direction of rotation of all the driven machine elements. Broadly speaking, Gear types may be grouped into five major categories. They are Spur, Helical, Bevel, Hypoid, and Worm. A lot of intricacies are there in the different types of gears. Actually The choice of gear type is not a very easy process. It is dependent on a number of considerations. Factors that go into it are physical space and shaft arrangement, gear ratio, load, accuracy and quality level. Types of Gears Types of Gears A number of gears are manufactured using different materials and with different performance specifications depending on the industrial application. These gears are available in a range of capacities, sizes and speed ratios, but the main function is to convert the input of a prime mover into an output with high

3- Internal Combustion Engines cooling and lubrication system (automobile engineering)

  in the previous sections we had discuss : Classification of Internal Combustion Engines and Engine Components (Course) Internal Combustion Engines Components 2 (Course)   In This  section we will discuss : -Describe and explain the operation of a typical cooling system for an industrial ICE. -Describe and explain the operation of a typical lubrication system for an industrial ICE. SECTION 3 Objective 7 Describe and explain the operation of a typical cooling system for an industrial ICE. ENGINE COOLING Small internal combustion engines are often air-cooled. Each cylinder or motor block is equipped with many thin fins creating an extensive cooling surface. This has the advantages of being simple and cheap, but the disadvantage of lack of control of the engine temperature because the cooling efficiency depends on the weather conditions. For high compression diesel engines, the combustion temperature can exceed 2000°C, and only 30 - 35% of the heat is converte

Fundamentals of Refrigeration and Air-Conditioning (course)

 Refrigeration: The process of removing heat. Air-conditioning: A form of air treatment whereby temperature, humidity, ventilation, and air cleanliness are all controlled within limits determined by the requirements of the air conditioned enclosure. 1.1 Basic physics – temperature The general temperature scale now in use is the Celsius scale, based nominally on the melting point of ice at 0°C and the boiling point of water at atmospheric pressure at 100°C. (By strict definition, the triple point of ice is 0.01°C at a pressure of 6.1 mbar.) On the Celsius scale, absolute zero is – 273.15°C. In the study of refrigeration, the Kelvin or absolute temperature scale is also used. This starts at absolute zero and has the same degree intervals as the Celsius scale, so that ice melts at + 273.16 K and water at atmospheric pressure boils at + 373.15 K. 1.2 Heat Refrigeration is the process of removing heat, and the practical application is to produce or maintain tempera
