BEARINGS
Bearings
bearings is a stationary machine element which supports rotating shafts or axles and it confines their motion. Natural, a bearing will be required to offer minimum frictional resistance to moving parts so as to results in minimum loss of power. In order to reduce frictional resistance, a layer of fluid may be provided.
Shafts
Shafts
The Shaft is a rotating machine element which transmits power from one member to another member.
It is one of the most common and basic machine element which are used in a variety of ways in mechanical equipment. It is used with power transmission elements such as gears, pulleys, flywheels, cranks, etc.
These shafts are designed to transmit the required torque and support the rotating element such as gears and pulleys. These elements produce bending moment in addition to torque. A shaft must be strong enough to sustain satic and dynamic loads.
