 Design Requirement of Machine Elements • A part of a machine that has motion relative to some other parts is called a machine element. Some machine elements may consist several elements; e.g., a ball bearing is a machine element and it consists an inner race, spherical balls, a retaining cage and an outer race. • A machine is as strong and reliable as its weakest element. Remember, a chain breaks at its weakest, link. Same is true for machine element. • The design requirement of a machine element is to ensure that it performs according to the specifications during its stipulated life span. In order to achieve the desired performance, the machine elements should satisfy the following important requirements: Strength, Rigidity , Wear resistance , Corrosion resistance, Ease of lubrication Minimum dimensions, weight and power loss in friction, Safety, Reliability Manufacturability, Maintainability, Conformance to specifications and standards, Minimum initial and life-cycle cost, Minimum L

SCREW JACK :-                                                         Screw Jack is a weight lifting mechanical device,which can be operated by turning a lead screw.It can lift heavy bodies verticaly for a short height. Part's Of Screw Jack  :-                                             A mechanical screw jack contains 7 parts in it.Which can be defined as below. 1.Body:-                 It is a main part of the screw jack which provides support to the Nut and the Lead screw in it.A body of screw jack is specially made by cast iron. 2.Nut:-                 It can be defined as a simple nut which is made of Gun metal.A lead screw goes upward and downward in it. 3.Screw:-                   It is a simple lead screw which goes upward and downward in but by turning by using Tommy bar. 4.Tommy Bar:-                             It is a simple mild steel bar.It is use to turn the lead screw by placing it in a hole of lead screw body.It's handle is being properly knurled for a bette

Foot step bearing :- Here we can see the 3D view of foot step bearing. Here we can see the section view half left part of the foot step bearing.This figure help you to imagine the part view and with the help of this figure you will draw easly the drawing of foot step bearing. Part's of foot step bearing :- Disassembled Part's of Bearing:- Assembly of  foot step bearing:- Top View of the Foot step bearing:- Here I have drwn the full section view of the foot step bearing.By using this figure we can draw the top view of the bearing easily. Front view of the Foot step bearing:- Here I have drawn the full sectioned front view of the foot step bearing.By talking some basic steps we easily can the front view of Bearing. Steps to draw parts in the sequence of:- 1 .Sole 2.Body or Block 3.Disk or pad 4.Bush with brass college 5.Shaft HINDI NOTE FOR THEM WHO CAN NOT UNDERSTAND ENGLISH WELL:- Follow this page. & Comment if you like this page.
