This proposed standard would not make any recommendations
regarding the required quality for any application. The
intent is to establish standard pre-finish quality classes for typical
finishing operations, which only include the inspection elements
that are important to properly evaluate pre-finish gear
quality as it applies to the finishing operation. It would be the
responsibility of the manufacturing/process engineer, quality
engineer, or other responsible individual to establish the
required pre-finish quality class for their application.
I make all the double helical gears that go into a gearbox - four
different gears in this unit. If the gear module for the bull gear and the
intermediate gear are the same (these are the two individual gears that
mate), and the gear module for the high-speed pinion and high-speed
gears are the same (these are the other two individual gears that mate
in the gear box as well), is it then possible to just use two hobs in this
setup to make all four gears, since they mate together with each other?
We are currently using a different gear hob for each gear.
During a year with a strong
dollar, tanked oil prices and a
number of soft markets that
just aren't buying, one might
expect spline manufacturers
to be experiencing the same
tumult everyone else is. But when
I got a chance to speak with some of
the suppliers to spline manufacturers at
IMTS about how business is going, many
of the manufacturing industry's recent
woes never came up, and instead were
replaced by a shrug and an "eh, business
is doing pretty well."
