Have you ever had to deal with chronic drive end ball bearing failures with a v-belt application? This article will take some of the mystery out of how to determine the load on a bearing, and how to increase the bearing capacity when necessary. The focus will be on bearing loading due to belt pull with v-belt drives. How to modify a motor to accept a cylindrical roller in place of a lower capacity ball bearing will also be detailed.
Calculating bearing load and life
The calculation of bearing loading may at first appear to be a daunting task due to the many variables involved. However, taken a piece at a time, the calculations are rather straightforward. An example will be used to illustrate this point.
