Loading Orientations for Gears
by Daniel H. Herring - April 28, 2010
Questions:
We have two questions for you today.
1. For gear wheels, which orientation is better for minimum distortion: a horizontal one (i.e. one above another with spacers in between) OR a vertical orientation (i.e. side by side of each, suspended on a horizontal bar)?
2. For pinion, which position is better: vertical (i.e. side-by-side in a vertical way) OR horizontal (i.e. one above another in horizontal way)?
Answers:
Most of the heat treaters in the U.S. are suspending gear wheels on a horizontal bar when possible. In other words, they are in a vertical position. Smaller gears (up to 5 mm) in particular work best this way. Larger gears (where the weight can cause them to sag) might have to lie flat on a tray. One, if not the biggest, factor that affects the distortion of gears is how they are placed and supported in the furnace by the fixturing.
