"What is the first indication of lubricant starvation?"

Heat is the direct consequence of lubricant starvation. Once any mechanical system becomes depleted of lubricant, and the lubricating film keeping gears, bearings or slides apart is no longer present to support or protect the surfaces, surface-to-surface contact will occur. When two surfaces slide or rub together, friction is produced, and from friction comes heat.

Before frictional heat is generated, the only way to detect lubricant starvation would be through vibration analysis. Vibration analysis can pick up subtle vibration changes in the machinery and may be able to identify lubricant starvation before the extreme heat from friction is discovered.

The effect of friction on the two surfaces rubbing together without lubrication will cause them to heat up quickly. The amount of heat generated will be in direct correlation to how fast the two surfaces are sliding or rotating. For example, gears rotating at only 60 rpm will take much longer to heat up than those rotating at 1,800 rpm. Without proper lubrication, gears rotating at faster speeds not only will heat up quickly but can also lead to failure of the machine.

In the image below, notice the difference between a good oil supply (full lubricant film), an impaired oil supply (boundary contact), and dry friction and wear (caused by lubricant starvation). Welding and galling occur when the two surfaces become so hot that they weld together and then tear apart, resulting in large amounts of debris. This is not something you want happening inside your machine.


Other signs that your machine is suffering from lubricant starvation include smoke, an unusual smell and the machine becoming hot to the touch. Smoke is caused by the heating of what is left of the lubricant. This is usually the case when you see some poor soul stranded by the side of the road with smoke pouring out from under the hood of his car.

Before a machine even begins to smoke, you can often smell the oil starting to heat up. This provides a good way to detect lubricant starvation.

Another excellent method is through touch. Your hands are very sensitive heat detectors and can identify subtle changes in temperature.

However, the most effective way to combat lubricant starvation without expensive diagnostic equipment is to check your machinery on a regular basis. Ensure your PMs are appropriate for each machine and take into account the changing conditions around the equipment, such as temperature, moisture and workload.

Please how did this make frontpage?

How wouldn't it make homepage?
This is important to Engineers, technicians, designers et al.
We are tired of all the stale news about snakes, tonto dike and death coming to home page, let better things, more educative and enlightening threads grace homepage.

This post reads incoherently, it feels like a hastily put together ad.
It's not very informative more like a rant.
If I May ask what's the criteria for posts getting o front page on this website? More and more lately the quality of front page posts has really tanked.
Really finding it harder to finds reason to visit this website lately

Informative

Thanks for this

So how may we please you, your majesty?

Some people are technically challenge and I understand. If you are in that category u won't understand this post

Nice topic, informative to vehicle users

I CONCUR. OIL IS THE BLOOD OF ANY ENGINE OR MACHINERY. EARLY CHANGE OF OIL AND FILTERS WILL
DEFINITELY PROLONG THE LIFE OF THE ENGINE OR MACHINERY.

@USELESS GOAT, REPENT FOR THE KINGDOM OF GOD IS AT HAND.

LOL at the funny comments

This shows that we really have a problem in this country.. .

70% readers thought its about z3x
20 find the topic useless..
And only a staggering 10 find it useful..
And we call the president dullard.. .


Nigerians are terrible and naturally backwards

If you are quite familiar with machines and how they work, it shouldn't be difficult for you to decipher what's written up there.
I guess this is the wrong post for you to show your dissatisfaction on the quality of post that makes the front page.

Clearly you are not ready to learn. No knowledge gain is waste.

Op, there's more to lubrication than what you put up there. Nice one though

uselessgoat:
Honestly my mind went the other way when i saw the word lubricant. I thought the article will teach about recommended lubricants when a girl's pusssy runs dry during a sex romp in bed. I was wrong nice article tho

lol naija chei true confession
