ESDU 88033:2012

ESDU 88033 is a guide to BS 436: Part 3: 1986 which provides a
rigorous analytical procedure for rating a gear of known size in
terms of allowable stresses or maximum power capacity. The method
quantifies all the factors known to affect gear performance, and it
requires a major reappraisal of traditional methods of gear design.
ESDU 88033 discusses the factors, introduced in the new Standard,
that affect material strength and the stresses induced, and
provides advice on the choice of materials and manufacturing
processes. An approximate method, compatible with BS 436: Part 3:
1986 enables the physical size of suitable gears to be determined
from a known power transmission requirement. The method is
summarised in a flowchart and illustrated by worked examples. A
discussion of methods by which the new Standard may be used to
generate gear design data for optimisation is included.
