Useful Facts About Industrial Clutch

By Melissa Brooks


There is a clutch of some sort inside almost every mechanical device, equipment, and machine that people use in the present world. Automatic and manual transmission cars, chain saws, cordless drills, and some yo-yos are among examples of machines that have clutches. There is no limit to the number of different products that function using clutches of some kind. Mentioning all of them here is impossible. The industrial clutch has many application in modern life.

A clutch refers to a mechanical gadget that is used in machines to engage and disengage power transmission, particularly from driving shafts to driven shafts. In their simplest applications, these devices disconnect and connect 2 rotating shafts. Shafts are usually classified as line shafts and drive shafts among other classifications. One shaft is usually connected to the power unit, which may be an engine or some other device.

On the contrary, the second shaft is used to offer a power output for the job. The movement made by this structure is rotational. However, linear clutches can also be produced. A torque-controlled drill is a good example of the way clutches work. In drills, one shaft is driven by the motor whereas the drill chuck is driven by the second shaft.

The role played by shafts in this structure is connecting together the two shafts. Clutches must provide a tight connection to make sure the two shafts are sealed together. This makes certain that the speed at which the two shafts rotate at is the same in what is known as an engaged set up. In the other structure, the two shafts rotate at different speeds although they are locked together in what is known as a slipping structure.

The third setup has shafts that are not locked together. Because the shafts are unlocked, they do not spin at the same velocity. A disengaged setup is the name given to this setup. Normally, frictional forces form the basis for operation in most clutches. The purposes served by friction clutches are many. In one function, they connect a stationary/moving member to a moving member to synchronize their movement.

Besides synchronizing speeds, the two members may be connected to one another with the intention of transmitting power. One member is usually connected to the source of power and the clutch is used to transmit energy/power to the second member. When there is a difference in speed between two members, it is referred to as slippage. In an ideal setup, slippage is supposed to be minimum.

Different materials have found use in making clutches in the past. At some point, asbestos was used. However, the dangers associated with asbestos made it to be dropped. Today, various materials are used, including ceramic material, and compound organic resin. Ceramic materials usually are used in very heavy applications like heavy-duty towing and racing. Thus, industrial clutches are made using ceramic.

A clutch damper is a device that is included in the clutch setup. When shafts are engaged or disengaged by clutches, the work of the damper is to soften the resultant response. Normally, there is a mechanism with clutch disc centers which acts as a damper in automotive applications. Driveline vibration is also minimized by dampers besides softening engagement and disengagement of power transmission by clutches.
