Chapter 7 Gears

Table 7-2 Commonly used diametral pitches Instead of using the theoretical pitch circle as an index of tooth size the base circle which is a more fundamental circle can be used The result is called the base pitch p b and it is related to the circular pitch p by the equation (7-8) 7 5 Condition for Correct Meshing Figure 7-5 shows two meshing gears contacting at point K 1 and K 2

What is Gear ratio? [How to calculate Gear Ratio with

The gear ratio is the ratio of the number of turns the output shaft makes when the input shaft turns once In other words the Gear ratio is the ratio between the number of teeth on two gears that are meshed together or two sprockets connected with a common roller chain or the circumferences of two pulleys connected with a drive belt

Transmission of motion and power

The gears are called spur gears Teeth of the spur gears are cut on the circumference of the cylindrical discs Spur gears can transmit higher power because of the contact between the mating gears is along a line Use :- Spur gears are used for transmitting power between two shafts when the axis of the driving and driven shafts are parallel and
