A wide range of devices which are used today have clutches. For example, manual transmission vehicles normally have multiple clutches. It is even more shocking to find out that automatic transition cars also contain clutches. Clutches are present in almost every device used in homes, public transport, companies, offices, , malls and factories. Products which have clutches include cordless drills, chain saws, bikes, and some yo-yos among others. This is what Industrial Clutch is all about.

Clutches find use in devices that have 2 rotating shafts. In devices like this, One shaft is driven by a pulley or motor of some sort while the other one drives a different device. In a cordless drill for instance, a motor drives one of the shafts while the second shaft rotates a drill chuck. A clutch is used to connect the two shafts.

When a clutch connects the two shafts, they might rotate at either different or same speeds. Cars are a perfect example of two shafts that move at different speeds. In cars, engines constantly rotate during motion even though cases where the wheels might not be actually moving exist. For this to take place, the wheels are normally somehow detached from the engine, which goes on rotating.

One of the major problems that clutches face is caused by friction. The surface of clutches is usually lined with a material similar to that used to line the shoes of drum brake or the pads of disc brakes. The materials usually wears over time, and once it is completely worn out, clutches will start to slip. Eventually, it will not be able to transmit any power from the engine to the wheels.

Before the 1970s, slippage was a very popular issue with vehicles. Clutches began developing issues after around 50,000 to 70,000 miles. However, minor improvements have been made with many clutches having the capability of being efficient after 80,000 miles. One major factor on which the effective functioning of clutches depend is maintenance. Clutches should be capable of lasting several years if proper maintenance is provided.

If clutches are poorly maintained, they can develop issues after covering as few as 35,000 miles. Vehicles which are always overloaded do experience problems with their clutches faster even as soon as new ones are installed. Heavy commercial vehicles are said to have issues even with new clutches.

The wearing off of the clutch disc is caused when the flywheel and the disc spin at different speeds. Otherwise, if the two spin at the same speed, the friction material and the flywheel spin in sync, there is no friction occurring to the clutch. In turn, less wear is experienced. That is why drivers that spin slip their clutches a lot wear them out faster.

Sticking also affects cars. This occurs when clutches fail to release properly and go on to turn the input shaft. That leads to grinding and it may cause a vehicle to fail to go into gear fully. Stretched or broken clutch cable, mismatched clutch components and misadjusted linkage may cause sticking.
