Presentation transcript:

Workings of the Reciprocating Saw Name: Michael Mak Objective: Understanding the Gear system of the Saw

Spur Gearing Straight Teeth Parallel Shaft Large Gear Reduction High Stress on Gear Teeth Very Loud and Noisy Small motor spinning very fast can provide power but not enough torque. Output speed reduced while torque increased Force to rotate or turn things

To reverse the direction of rotation To increase or decrease the speed of rotation To move rotational motion to a different axis To keep the rotation of two axes synchronized

A Different Gearing
