In this article, we learn what is machine and the types of machine elements.
What is Machine?
The machine is a device that receives energy in some available form and utilizes it to do some particular type of work.
The machine is also defined as a device consisting of fixed and moving elements that modify energy and transmit it in a useful form.
For example Lathe machine in which electric energy supplied by the motor is utilized for doing some useful work such as turning, facing, chamfering, etc.
A machine element is an individual component or group of components that perform a specific function.
It may be used for power transmission, for holding the components, or for providing support.
Types of Machine Elements
According to the functions to be performed, the machine elements are divided into the following three categories.
1. Power Transmitting Elements
These elements are used to transmit power from one part to another part of a machine.
For example Shafts, Gears, Belts, Pulleys, Clutches, Cams, Chains, etc.
2. Holding elements
These elements are used to hold various parts of a machine.
For example Nuts, Bolts, Pins, Rivets, etc.
3. Supporting elements
These elements are used to support various parts of a machine.
For example Bearings, Axles, Brackets, Beds, etc.
