Bearing Arrangement (Machine design concepts)

Description

INTRODUCTION

Bearings are an integral part of anything that rotates, be it your car, the bus you use for community transport, the aircraft that you travel in for vacation or on business, any industrial machine like power plant equipment or wind mills. The applications are endless.

Our specialization series on Bearing Application and Theory provides a detailed introduction the basics of bearings, basics of bearing failures, popular types of bearings and will study design concepts concerning fits and tolerances.

LEARNING OBJECTIVES

This course on Bearing Arrangement (Machine design concepts) is the FOURTH of our specialization series on Bearing Application and Theory. It is designed as an introduction to professionals that wish to gain a basic knowledge of working with bearings.

The objective of this series is to help gain understanding of the basic parameters behind use of bearings, the designation, important design features, failures, lubrication and some popular bearing types. We will also offer some basic trouble shooting tips. The series covers these concepts with enough details that provide the participants of this course an introduction to working with bearings and its applications.

One of the most important contributors to bearing failure is design of the bearing arrangement. This course on Bearing Arrangement (Machine design concepts) describes two concepts of machine design which are very important for the design of the arrangement and its optimal operation namely Fit and Pre-loading.

We will start with fit. We describe important definitions and three types of fit. Some guidelines are described. After this section, the user will be able to select the correct fit for the application. We follow fits with pre-loading. Pre-loading is very important to increase life of the arrangement as well as lead to reduced noise and vibrations. The section ends with description of two popular applications like electric motors and automotive.

At the end of the course, the participants will understand the guidelines for selection of Fit and Pre-loading and would acquire an understanding of these two important design parameters. We will also offer some additional reading resources for further learning.

This course is full of practical guidance based on front-line bearing industry experience of the instructor. 

WHO SHOULD TAKE THIS COURSE

Our specialization on Bearing Application and Theory is a series of courses that are designed to help those that need basic and intermediate knowledge of bearings.
