Please help me finding this question. Power = 6 kW
The maximum sliding velocity of the teeth of two gear wheels in mesh is 0.32 m/s. The wheels are of module 5 mm and have 32 and 44 teeth respectively. The addendum for each wheel is 1.2 times the module and the pressure angle is 20°. Calculate: 2.1. The number of teeth in contact. 2.2. The angular speed of each wheel.
A pickup truck is driving at a speed of 100 km/h on a leveled road. This truck has4 wheels of the same diameter of 400 mm and drives at a gear ratio of 5 to 1 ifits gearbox 5th gear is selected. The gear’s teeth are of involute form with amodule of 8 mm, an addendum is double the module, and the pressure angle isequal to 20° .1.1. If the driving shaft of the front wheels of the truck is connected to the output shaftof the gearbox, determine the number of teeth on the pinion to avoid interferenceand the corresponding number of teeth on the gear wheel.
