Flange-mounted helical gear unit with extended bearing hub RX. Generally speaking, when two spur gears are in mesh, the gear with more teeth is called the "gear" and the one with the smaller number of teeth is called the "pinion". (AGMA = American Gear Manufacturers Association ISO = International Organization for Standardization) • Both allow for wear, bending and pitting resistance with equation modifiers that are similar, but not identical. First, decrease tooth thickness by sinking the hob deeper into the blank than the theoretical. – don’t use a Para-Flex when AGMA 11 balance is required Only the D-Flex and Disc Coupling have an “off-the shelf” balance standard (AGMA 9) specified All couplings can be balanced to improve.
