L type pulley tooth depth, 2.13mm (0.0838'') or 2.68mm (0.1055'')?
(OP)
I have been using a L type hobber in my factory for years, never had problem with it. But recently the pulley I cut had been rejected by the QC dept. of my client because of the cutting depth.
On the drawing it says the cutting depth should be 2.13mm. And I looked up on Misumi-ec.com, their type L pulley has a tooth depth of 2.13mm too. (http://tw.misumi-ec.com/vona2/detail/110300405670/...)
But my hobber has a cutting depth of 2.68mm.
I looked up on the internet and found a graph that has 3.25 for L type belt tooth depth (http://www.instructables.com/id/Types-of-Timing-Be...)
What's the correct tooth depth for L type pulley, anyone know? (and also the reason for these variation in depth?)
