Industrial Lubrication
Mechanical Skills
Course 1 – Fundamentals of Lubrication
Prerequisites: This lesson is designed so that no prior knowledge is required. However, a know-ledge of applied mathematics is recommended.
Description: This lesson explains the concepts of lubrication, friction, and viscosity and demonstrates the benefits of a proper lubrication program. Additionally, the properties of common solid, semi-solid, and liquid lubricants are described as well as the benefits associated with synthetic lubricants and the functions of additives and inhibitors. Common types and causes of lubricant contamination are described and proper methods of lubricant storage are demonstrated.
Objectives:
- Define lubrication
- Explain the benefits of a proper lubrication program
- Define friction
- Identify factors that contribute to friction
- Identify the three basic types of friction
- Describe three types of lubrication applications used to reduce friction
- Define viscosity
- Describe three types of liquid lubricants and some typical applications
- Describe the properties of liquid lubricants
- Describe types of semi-solid lubricants and some typical applications
- Describe conditions or circumstances under which it would be preferable to use grease as a lubricant
- Describe the properties of semi-solid lubricants
- Describe types of solid lubricants and some typical applications
- Describe the properties of solid lubricants
- Identify some of the benefits of using synthetic lubricants
- Explain the function of additives and inhibitors
- Describe types of lubricant contamination
- Describe how to prevent lubricant contamination
- And describe proper methods of lubricant storage
Course 2 – Lubrication Maintenance
Prerequisites: This lesson is designed for participants familiar with the fundamentals of lubrication. A knowledge of applied mathematics is recommended.
Description: This lesson explains and demonstrates how various types of lubrication systems operate, including ring, bath, splash, constant level and forced feed lubrication systems. Participants learn pertinent maintenance checks to make for each type of system. Manual devices used to apply lubricant are covered as well as the purpose of filters and the importance of filter maintenance in lubrication systems. Additionally, the lesson indicates the benefits of oil sampling and analysis and identifies several factors which can cause lubrication failure.
Objectives:
- Explain how ring lubrication systems operate
- Explain how bath lubrication systems operate
- Explain how splash lubrication systems operate
- Explain how constant level lubrication systems operate
- Perform a check on a natural feed lubrication system and determine machine condition
- Describe how to add oil to a natural feed lubrication system
- Describe the operation of forced feed lubrication systems
- Explain the differences between natural feed and forced feed lubrication systems
- Perform a check on a forced feed lubrication system and determine machine condition
- Identify various devices used to apply lubrication manually
- Describe how to apply the proper amount of grease to a bearing
- Explain the purpose of filters in a lubrication system
- Explain the differences between surface filters and depth-type filters
- Explain why filter maintenance is important
- Recognize indications that a filter must be cleaned or replaced
- Describe how to clean a filter
- Explain the benefits of following a lubrication schedule
- Interpret information on a lubrication schedule
- And explain the benefits of oil sampling and analysis
