    Function of transmission box (gear box) in automobile: The transmission box which is also known as the gear box is the second element of the power train in an automobile. It is used to change the speed and torque of vehicle according to variety of road and load conditions.

  • The Importance of Bearing Selection on Gearbox

    April 18, 2018. Large reduction gearboxes are designed to transmit high torque by reducing the high input speed to the desired output speed. This being the reason a gearbox is widely used and a common piece of equipment through heavy industry driving conveyors, mills, crushers and pumps. The gears throughout a gearbox are precision manufactured

    Also, bevel gears are specially designed to change the direction between the input and output shafts of the gearbox, for example, to convert the input of a horizontal axis to a vertical axis output. Another type of gear system is the so-called endless screws, which can transverse changes in the direction of the input and output axes.

  • What is Gear Box? What are Main Components of Gear

    In an gear box, the gear teeth and other moving metal must not touch. They must be continuously separated by a thin film of lubricant. This prevents excessive wear and early failure. Therefor a gearbox runs partially filled with lubricant oil. This is all about what is

  • What are the applications of a gearbox? Quora

    Most modern gearboxes are used to increase torque while reducing the speed of a prime mover output shaft (e.g. a motor crankshaft). This means that the output shaft of a gearbox rotates at a slower rate than the input shaft, and this reduction in
