lubricant is a substance, usually organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles,
or heating or cooling the surfaces. The property of reducing friction is known as lubricity. In all types of machines, the surfaces of moving or sliding or rolling parts rub against each other. Due to this movement against surfaces in contact, friction results. Friction causes a lot of wear and tear and even generates heat. All these result in loss of efficiency and lubricants is the answer. Hence any substance put between two moving/rubbing/sliding surfaces with a view to reduce or eliminate frictional resistance is a lubricant. It is also worthy of note that the demand for lubricant is huge and especially in Industries.
There are different types of LUBRICANTS.here in the academy we will be training students on the following types of LUBRICANTS.
1.Automatic transmission fluid (ATF)
2.Brake & Clutch Fluid
3.Chain lubricant
4.Cutting Oil
5.Engine Oil
6.Engine Oil Coolant
7.Gear Oils
8.Hydraulic Oil
9.Greases
10.Machine Oil
11.Penetrating Oil
12.Radiator Coolant
Automatic transmission fluid (ATF) is a kind of transmission fluid used in vehicles with self-shifting or automatic transmissions. It is typically coloured red or green to distinguish it from motor oil and other fluids in the vehicle.The fluid is optimized for the special requirements of a transmission, such as valve operation, brake band friction, and the torque converter, as well as gear lubrication.ATF is also used as a hydraulic fluid in some power-assisted steering systems, as a lubricant in some 4WD transfer cases, and in some modern manual transmissions
Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, and light trucks. It is used to transfer force into pressure and to amplify braking force. It works because liquids are not appreciably compressible..
Chain lubrication is needed mainly to slow the wear between the pins and bushings in the chain joints, to flush out wear debris and foreign materials, and to smooth the chain’s engagement with the sprocket. Additionally, lubrication may be needed to inhibit rust and corrosion, to carry away heat, and to cushion impact forces.A chain lubricant should have low enough viscosity to penetrate into critical internal surfaces and high enough viscosity, or necessary additives, to maintain an effective film at the prevailing temperature and pressure.
