Two spur gears are to have a ratio of 9:3 and a 7mm module. If the center distance is to be approximatively 200mm, calculate the following:o Circular pitch value;o Number of teeth on the wheel (gear);o Number of teeth of the pinion;
The following data relate to two meshing gears:
Velocity ratio =1:3;Module: 4mm; Pressure Angle: 20°; Center distance: 200 mm
