What is a damper pulley?

What is a damper pulley?

A damper pulley, commonly known as a crankshaft pulley, is a pulley mounted at the front end of the crankshaft. It drives the acces- sory belts, which in turn drive the alternator, air conditioning compressor, power steering pump, water pump etc. The simple pulley has a damping effect on crankshaft stresses.

How many types of vibration dampers are there?

Introduction Damping: Types of damping  Material damping,  structural damping Measurement 3. Dynamic dampers: DAMPING:  Generally damping means the mechanical energy is converted into the heat energy in a vibrating system The net result is: Reduction of dynamic load and displacement Which improves fatigue life.

Where is the damper pulley located on a car?

NOT JUST DAMPERS! A damper pulley, commonly known as a crankshaft pulley, is a pulley mounted at the front end of the crankshaft. It drives the acces – sory belts, which in turn drive the alternator, air conditioning compressor, power steering pump, water pump etc. Modern engines produce a large amount of torsional vibration in the crankshaft.

What kind of pulley does a diesel engine use?

Eg : DPF359.03. THE SINGLE-BLOCK PULLEY OR DAMPER. Widely used on diesel and petrol engines. It consists of 3 parts, 2 metal (iron, steel or aluminum) and a rubber ring that connects the metal parts together.

How are harmonic dampeners and balancers used in an engine?

Adding mass to the crankshaft assembly is one solution for minimizing vibrations in some engines, but this approach increases rotating mass of the crank and overall weight of the vehicle. The other cure is a crankshaft pulley with a harmonic dampener/balancer. A harmonic balancer is like a punching bag for the crankshaft.

Is the harmonic damper the same as the vibration damper?

Harmonic damper. A harmonic balancer (sometimes crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator,…

What does a harmonic pulley damper do?

The harmonic balancer (also called “crank pulley damper”), connected to the crankshaft of an engine, reduces engine vibration and serves as a pulley for the drive belts. The balancer or “damper” is composed of two elements: a mass and an energy-dissipating element.

What does a bad crankshaft pulley do?

Home » Blog » Mechanics » Bad Crankshaft Pulley/Harmonic Balancer Symptoms & How to Remove It The crankshaft pulley/harmonic balancer is a mechanical system that distributes power to other systems of a vehicle. This component is connected to the crankshaft, which is another part that transforms linear motion from the pistons to rotational movement.

Why is the crankshaft pulley and harmonic balancer important?

You may think that the crankshaft pulley is not as important as other parts of your car’s engine, but actually, it is vital to the proper operation of your vehicle. The crankshaft pulley comes with a harmonic balancer. Just from the name, the crankshaft Pulley/harmonic Balancer is a mediator between pistons and crankshaft.
