Automotive gear manufacturers have implemented significant improvements in external planetary gear manufacturing yielding quieter gears. In addition, process stability has increased due to the post-heat treatment finishing processes employed. This article explains various complete solutions for cutting and finishing internal ring gears.
Back around 2005-2010, the most exciting things that were happening in broaching had little to do with broaching. What
was happening - and continues to
evolve today - was the emergence of on-the-edge CNC, software and servo drive
technology. Together, they practically
transformed a metalworking process as
old as water into a viable, alternative
consideration for producing high-volume
part runs.
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."
Broaching is a machining technique commonly used to cut gear teeth or cam profiles for the high volume manufacture of power transmission parts used in vehicles (Refs. 1–2). This article shows how the right gear blank material can make all the difference if you want to get more parts out of each tool.
In 1964, a young and tidy Bob Dylan sang away in that infamous voice of his,
all nasally and grating yet wonderfully distinct, opining to the fervent masses: “The times, they are a-changin.”
At the dawn of the Industrial
Revolution, so-called mechanics
were tasked with devising the precise methods that would make mass production possible. The result was the first generation of machine tools, which in turn required improved tooling and production methods.
