Document Summary
The analysis of spur gears provided the background of how forces and power are transmitted in rotational motion. Spur gears have a uniform thickness with teeth spanning the full thickness, and as such they are designed to have instantaneous contact across with face width. The total force between gears f, along with the components ft and fr, all act in the same plane, a plane normal to the axis of rotation. Because of this, bearings which support shafts on which spur gears are mounted only have to be supported in the radial direction. Simple stops can be used at the end of the rotating shafts because forces along the shaft are negligible. These axes of action and forces will be rotated and changed in the 3 types of gears in this lesson: First the main features of each type of gear will be presented, and detailed analysis later on.
