杜邦POM齒輪設計(pdf 11)

A number of years ago, DuPont commissioned a series of
extensive gear tests on gears of DELRIN? acetal resin and
ZYTEL? nylon resin, which resulted in the information
summarised in Tables 8.02 and 8.03. This data can be
combined with environmental operating conditions to
arrive at an allowable tooth bending stress.
Whether similar experience exists or not, it is essential
that a prototype mould be built and the design carefully
tested in the actual or simulated end-use conditions.
