Load Ratings And Fatigue Life For Ball Bearings
سال
: 1990-01-01
چکیده: INTRODUCTION
Purpose of Standard
Ball bearing performance is a function of many variables. These
include the bearing design, the characteristics of the material
from which the bearings are made, the way in which they are
manufactured, as well as many variables associated with their
application. The only sure way to establish the satisfactory
operation of a bearing selected for a specific application is by
actual performance in the application. As this is often
impractical, another basis is required to estimate the suitability
of a particular bearing for a given application. This is the
purpose of this standard.
This standard specifies the method of calculating the basic
dynamic load rating of rolling bearings within the size ranges
shown in the relevant ANSI/AFBMA standards, manufactured from
contemporary, commonly used, good quality hardened steel in
accordance with good manufacturing practice and basically of
conventional design as regards the shape of roIling contact
surfaces.
This standard also specifies the method of calculating the basic
rating life, which is the life associated with 90% reliability,
with commonly used material and manufacturing quality, and with
conventional operating conditions. In addition, it specifies the
method of calculating adjusted rating life, in which various
reliabilitles, special bearing properties and specific operating
conditions are taken into account by means of life adjustment
factors.
Furthermore, this standard specifies the method of calculating
the basic static load rating and the static equivalent load for
ball bearings within the size ranges shown in the relevant ANSI!
AFBMA Standards, manufactured from good quality hardened steel, in
accordance with good manufacturing practice and basically of
conventional design as regards the shape of roIling contact
surfaces.
