INTRODUCTION FOR REDUCING BREAKDOWN BY EFFECTIVE LUBRICATION AND BEARING MAINTENANCE
A bearing is a machine element that constrains relative motion and reduces friction between moving parts to only the desired motion. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Many bearings also facilitate the desired motion as much as possible, such as by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.
The simplest bearings are bearing surfaces, cut or formed into a part, with varying degrees of control over the form, size, roughness and location of the surface. Other bearings are separate devices installed into a machine or machine part. The most sophisticated bearings for the most demanding applications are very precise devices; their manufacture requires some of the highest standards of current technology.
COURSE OVERVIEW
This course is industry designed, to provide a broad understanding of the improvement methodology, concepts, and process. The methodology is presented with case studies and examples drawn from service, business process and applications. With a heavy practice orientation, as much as a third of your time will be spent working through interactive practical exercises and assessments. This course is designed to concepts and methodology.
COURSE OBJECTIVES
This training program is designed to provide an understanding of engineering related problems related to industry globally and a clear sense of what is required to effectively structure, establish measurements and solve problems. Participants will learn the goals and deliverables behind the solutions. Methodology as well as the most commonly used tools within each phase will be discussed. Participants will also learn how to support a problem solving initiative within their organization.
LEARNING OUTCOMES
On successful completion of this course, the participant should be able to:-
- Understand the benefits and implications of bearing maintenance.
- Use the basic concept of bearing maintenance to evaluate the capability of a process.
- Recognize the engineering problem solving model used to improve processes.
- Integrate the bearing maintenance effort with other process improvement initiatives.
TRAINING METHODOLOGY
- The latest educational methods and strategies will be utilized.
- The course is designed to maximize delegate participation.
- Questions and answers are encouraged throughout and at the daily wrap-up sessions. This gives participants the opportunity to discuss with the presenter their specific problems and appropriate solutions.
- The course shall be conducted through lectures, case studies, group discussions and exercises to reinforce participant’s learning.
TARGET AUDIENCES
Operation and maintenance personnel , facilities personnel, purchasing personnel
COURSE FORMAT
The course consists of formal content presentation interspersed with content quiz sessions. The presenter’s style involves intensive participant participation.
