1. LUBRICATION METHODS

2. INTRODUCTION
This slide show has been designed to educate you about different systems & methods of lubricating a mechanical process. All of these will provide oil or grease application manually and automatically & include both methods.

3. MANUAL LUBRICATION METHODS

4. GREASE APPLICATION
THERE ARE A FEW METHODS OF APPLYING GREASE MANUALLY INTO AN APPLICATION:
SPREADING BY HAND
GREASE PACKING
GREASE GUN

5. SPREADING GREASE BY HAND
THIS USUALLY DONE ON OPEN MECHANICAL SYSTEMS AND SHOULD USUALLY BE DONE USING A SPATULA. IF THIS IS TO BE DONE VIA USING OUR HANDS GLOVES SHOULD BE WORN, AS GREASE CAN BE CLASSED AN IRRITANT & STANDS THE RISK OF REMOVING ANY NATURAL OILS FROM OUR SKIN AND CAN DRY THE OUT THE SKIN & CAUSE CRACKING OR RASHES TO OUR HANDS.

6. GREASE PACKING
THIS METHOD IS USUALLY APPLIED TO A MECHANICAL COMPONENT SUCH AS A BEARING (IMAGE TO THE RIGHT), AND THE GREASE IS ACTUALLY PACKED DIRECTLY INTO THE PLACE WHERE IT IS NEEDED. ONCE THE REQUIRED AMOUNT OF GREASE HAS BEEN LOADED, THE APPLICATION IS EFFECTIVELY CLOSED UP WITH THE GREASE SEALED UP WITHIN. THIS METHOD IS ALSO USED FOR CAR COMPACT VELOCITY JOINTS.

7. GREASE PACKING

8. GREASE PACKING

9. SEALED SIDE BEARING
THIS BEARING HAS BEEN PACKED WITH GREASE AND BOTH SIDES OF THE BEARING HAVE BEEN SEALED PEMANENTLY WITH PLASTIC SEALING RINGS. THE GREASE IS PERMANTLY TRAPPED WITHIN, NOT LETTING GREASE TO ESCAPE OR ALLOWING ANY EXTERIOR CONTAMINATION IN

16. NIPPLE MECHANICS

17. CORRECT USAGE WEAR CORRECT PPE WHEN USING
DO NOT CONTAMINATE THE GREASE WHEN LOADING THE GREASE GUN
ENSURE THE ROD IS FULLY RETRACTED AND LOCKED IN PLACE BEFORE LOADING WITH GREASE
ALWAYS ENSURE THE GREASE GUN BODY IS CLEANED SO AS TO PREVENT THE GUN FROM BEING SLIPPERY

20. BALL VALVE OILER

21. BALL VALVE OILER

22. Correct Usage Wear correct PPE when using
Do not contaminate the grease when loading the grease gun
Ensure the rod is fully retracted and locked in place before loading with grease
Always ensure the grease gun body is cleaned so as to prevent the gun from being slippery

23. AUTOMATIC OIL LUBRICATION SYSYEM
Gravity fed
Capillary action
Oil filled bath / splash fed
Force fed
Air / oil mist
Centralised Lubrication
Total Loss Lubrication

24. Total Loss Lubrication
Total loss lubrication involves creating a thin oil-film between moving parts which is renewed at regular intervals by an automated lubrication system
This type of lubrication is used for internal combustion engines and steam engines.
This method of lubrication will be covered during the following automatic lubrication systems
These will need to be identified.

25. GRAVITY FED OIL LUBRICATION

26. GRAVITY FED OIL LUBRICATION

27. GRAVITY FED OIL LUBRICATION
Maintenance of this system is:
To keep the oil supply regularly replenished
Ensure the control valve is freely moving
Ensure that the supply orifice is free from blockages

28. GRAVITY FED OIL LUBRICATION

29. Milling M/C Quill

30. CAPILLARY ACTION OIL LUBRICATION

31. CAPILLARY ACTION OIL LUBRICATION
Maintenance of this system is:
To keep the oil supply regularly replenished
To ensure the wick is in good condition & in the correct position
Ensure that the supply orifice is free from blockages

32. SPLASH FED / OIL BATH
This is by far the simplest method of lubrication by oil. This works by the rotating components within the mechanical system operating at speed and effective dipping themselves into a bath of oil whilst they are turning. This method is preferred due to its effectiveness in lubricating for example bearings. Typically, the oil level should almost reach the centre of the lowest rolling element when the bearing is stationary. As the entire system works in rotation, the oil will be effectively picked up and spread / sprayed onto the neighbouring parts with the sealed system chamber.

33. SPLASH FED / OIL BATH

34. SPLASH FED / OIL BATH ANIMATION
The following animation shows how a splash type lubrication system is used in a car engine. This method will ensure that a vast majority of the relevant parts inside a car engine are supplied with lubricating oil.

35. FLINGER DISK / RING

36. SPLASH RED / OIL BATH LUBRICATION METHOD
Maintenance of this system is:
To ensure the oil is kept replenished at the correct levels
Make sure that the oil is kept in good condition and free from contamination
Ensure the flinger device is in good condition and is able to perform its task

37. FORCE FED OIL LUBRICATION
This system is also known as circulating oil & simply involves passing the lubricating oil around the system of mechanical components that require lubricating, and frequently is used during higher speeds, it is here where temperature increases. To ensure effective lubrication and extended life of the oil and parts that are being lubricated, pump would be used to drive the lubricant through the system through a filter and possibly a heat exchanger along the way.

38. FORCE FED OIL LUBRICATION

39. FORCE FED OIL LUBRICATION
Maintenance of this system is:
Ensure the oil filter is in good condition and functional
Ensure the oil is in good condition (contamination free)
Make sure the oil is in good supply
That the pump is functioning corectly

40. COMBINED SYSTEMS
It may be necessary at time to employ more than one lubrication system, this would usually ensure even lubrication takes place to reach all of the mechanical working parts within a machine or process. The next slide shows a system that uses both force fed oil and oil bath systems.

42. COMBINED SYSTEMS
The following video clip will show how this works, utilising additional necessary parts

43. INSIDE A CAR ENGINE

44. Oil Filter BYPASS VALVE FILTER ELEMENT
In an oil filter, the oil flows into the filter on the outside of the filter element, passing through the filter element and out to the engine.
The bypass valve, shown on the cutaway filter above, is to allow the oil to bypass the filter element should the element become plugged. (Thick oil,high revving)

45. MAGNETIC SUMP PLUG

46. OIL MISTING SYSTEM

47. OIL MISTING DEVICE

48. COMPRESSED AIR NOZZLE

49. OIL MISTING SYSTEM Maintenance of this system is:
That the supply feed is not blocked
The supply is readily pressurised
The oil supply is adequate
All the heaters are working

50. Centralised Lubrication
Used within:
Workshop M/Cs
Mechanical systems
incorporating bearings
Automotive applications
Hydraulic systems such as
a mechanical digger
A mechanical system including
multiple parts

53. AUTOMATIC GREASE LUBRICATING METHODS

54. INTRODUCTION
THIS SLIDE SHOW HAS BEEN DESIGNED TO EDUCATE YOU ABOUT DIFFERENT SYSTEMS & METHODS OF LUBRICATING A MECHANICAL PROCESS. ALL OF THESE WILL PROVIDE GREASE APPLICATION AUTOMATICALLY & INCLUDE:
SPRING ACTIVATED GREASE CUP
AUTOMATIC ACTIVATED GREASE CARTRIDGE

55. SPRING ACTIVATED GREASE CUP
SPRING LOADED (SPRING FEED) – PROVIDES A CONTINUOUS SUPPLY OF GREASE UNDER PRESSURE OF A SPRING, SUITABLY FOR THINNER TYPES OF GREASE AND SHORT DIRECT FEED.

56. SPRING ACTIVATED GREASE CUP

57. AUTOMATIC ACTIVATED GREASE CARTRIDGE
THESE TYPES OF GREASE LUBRICATORS NOT ONLY WORK ON THE USING THE SCREW OPERATED AND SPRING METHODS, ANOTHER TYPE IS USED. THIS OTHER TYPE USES A CHEMICAL REACTION TO DRIVE THE GREASE OUT OF THE DISPENSING UNIT IN PROGRAMMABLE INTERVALS INTO THE EXACT DESTINATION DESIRED.
