  As we know the torsion Equation Where τ  = Torsional stress induced at the outer surface of the shaft (Maximum Shear stress). r  = Radius of the shaft. T  = Twisting Moment or Torque. J  = Polar moment of inertia. C  = Modulus of rigidity for the shaft material. l   = Length of the shaft. θ  = Angle of twist in radians on a length. From Torsion Equation we can consider It can be written as The polar moment of inertia will be calculated from the following equation. The polar moment of inertia for a circular cross-section is From this, the maximum torque that can be transferred thru the shaft can be written as From the above equation, we can calculate the unknown factors. In our case, the shaft diameter is the unknown factor.

What is Hydroforming ? Hydroforming is a metal fabricating and forming process which allows the shaping of metals such as steel, stainless steel, copper, aluminum, and brass. This process is a cost-effective and specialized type of die molding that utilizes highly pressurized fluid to form metal. Generally there are two classifications used to describe hydroforming, Sheet hydroforming Tube hydroforming Sheet Hydroforming Sheet hydroforming uses one die and a sheet of metal; The blank sheet is driven into the die by high pressure water on one side of the sheet forming the desired shape. Tube Hydroforming If the shape contains bends that deviate from a straight line, the raw tube is loaded into the tube bender. This bends the tube giving it the necessary curvature in order to fit into the dies. The bent Tube is then typically placed in either our 200 or 500 ton pre-form press. These presses will initiate the forming and shape change of the ...

Rims are incredibly important to the entire wheel component which means rim manufacturing plays a crucial role in the production of wheels. xiaoys’s steel wheel rim manufacturing line is used to manufacture wheel rims for passenger cars, trucks, bus, tractors, farm vehicles and construction vehicles wheels according to user’s requirements, we can design and manufacture the rim production line to make 10 to 54 inch steel wheel rims PROCESS :- STEEL STRIP CUTTING RIM BEND FEEDING DEBURRING FOR BOTH SIDE STAMPING MARK RIM BEND COOLING FLATTENING WELD JOINT AC FLASH BUTT WELDING TRIMMING WELDING JOINT PLANISHING END CUTTING COOLING RE-ROUNDING INITIAL FLARING 1 ST ROLL FORMING 2 ND ROLL FORMING 3 RD ROLL FORMING 4 TH ROLL FORMING EDGE FLANGING FINAL EXPANDING VALVE HOLE PUNCHING PRESS DISC IN TO RIM COMBINED WELDING FOR RIM AND DISC BOLTING RIM AND DISC FEEDING, RIM BANK COILING ( 1-4 ) A coiler machine is an essential machine that is used...

There are total Eight steps which are required in making propeller shafts ·          Pattern Making ·          Molding ·          Casting ·          Fatling ·          Machining ·          Grinding ·          Balancing ·          Surface Finishing Pattern Making   -   It is a process where from the design of the propeller shaft we make the similar pattern of Fibre glass and putty. Molding   -   It is the process to make the mould to get a propeller shape. The mold is made from fine sand and Hardener agent. Casting   -   It is a process where molten metal liquid of propeller material such as manganese bronze will ...

How DP Test Works??? Dye Penetrant Examination is commonly used for weld components. In this technique low viscosity liquids are allowed to penetrate in the surface openings and after penetration, liquid is made to extract out again by means of some developers. That is why it is also known as Liquid Penetrant Examination for the evaluation of weldment.  The examination includes five steps ·         Cleaning ·         Introducing Penetrant ·         Penetrant Removal ·         Introducing Developer ·         Examination Cleaning: - To start, the test surface is need to be cleaned with the help of wire brush or some old cloth using a suitable. cleaner. The surface must be cleaned from organic compounds (oil and grease), dust, scale and other pollutants because an even su...

Raw Materials Steel alloys are the most commonly used spring materials. The most popular alloys include high-carbon Design Various mathematical equations have been developed to describe the properties of springs, based on such factors as wire composition and size, spring coil diameter, the number of coils, and the amount of expected external force. These equations have been incorporated into computer software to simplify the design process. The Manufacturing Process 1 Cold winding. Wire up to 0.75 in (18 mm) in diameter can be coiled at room temperature using one of two basic techniques. winding the wire around a shaft called an arbor or mandrel A guiding mechanism, such as the lead screw on a lathe, must be used to align the wire into the desired pitch (distance between successive coils) as it wraps around the mandrel. 2 Hot winding. Thicker wire or bar stock can be coiled into springs if the metal is heated to make it flexible. Standard industrial ...
