Design of machine element
Design of Machine Element[edit]
"Design of Machine Element" consists of designing a machine element with the use of scientific principal and engineering approach so that it is most efficient and safe in its functionality.
Design[edit]
The word “Design” in “Design of Machine Element” refers to the finding appropriate size (and shape) of Machine Element that can sustain stresses developed in it in particular application.Safety is a very important factor that should be taken into account while designing with other factors, that's why Machine components are designed for stress more than 'maximum stress developed in a particular application' due to safety consideration,it is taken into account by the factor of safety.
Design consideration[edit]
Design of 'Machine element' influence by the following factor-[1]
- Strength of the material
- manufacturing consideration
- Cost of material and manufacturing process
- Friction
- Safety
- Thermal consideration
- Shape of the machine element
- Size of the machine element
- Surface Finish
Design process[edit]
1.The first step in designing a machine element is 'Defining Function of an element'.[2] 2.Finding applied force on machine element 3.material selection 4.Finding mode of failure 5.Determining dimension of the machine element
Machine Element examples[edit]
- Shaft
- Key
- Coupling
- Bearing
- Clutch
- Brake
- Spring
- Threaded joint
- Welded joint
- riveted joint
- Power screw
- Gears
