Shaft design calculation pdf

Shaft Design Procedure 1. Determine the rotational speed of the shaft. 2. Determine the power or the torque to be transmitted by the shaft. 3. Determine the design of the power-transmitting components or other devices that will be mounted on the shaft, and specify the required location of each device. 4. The crank is at an angle with the line of the dead center positions and subjected to maximum torsional moment. I I Case. Case II: The crank is at an angle with the line of the dead center SLITTING: This machine makes a slit in the right side of the shaft to fit in the engine. The cutter used is a Saw cutter and pneumatic deburring is done here. 9. AIR & WATER CLEANING: This is the Washing Machine where water and air jets are used to clean the component of dust, oil, chips etc. 10. INSPECTION: This is a Measuring Machine used to Design ParameterT for Spline Connections Dr. Hermann J. Stadtfeld. Introduction. Splines are machine elements that connect a shaft with a rotor. Next to transmitting torque, the spline might also be utilized to center the rotor to the shaft. It is interesting that the spline's tooth profiles are involutes, although the involute profile does Cardan Shaft Design Calculation Research Paper DESIGN DEVELOPMENT AND STRUCTURAL ANALYSIS.

Therefore apart from the strength calculations, rigidity of a number of parts is also calculated as ratio of the actual displacements (deflections, Steps in shaft design Steps in the shaft design are: 1. Define shaft topology 2. Specify driving elements 3. Free body diagram 4. Select bearings 5. Consider shaft deflection and However, most real machine part will have varying cross sections. For example, shafts often are stepped to different diameters to accommodate bearings, gears, pulleys, etc. a shaft may have - Final shaft surfaces are to be ground - Required design reliability of 99% - Gears 2 & 4 will experience shock loading - Gear 3 will experience normal loading - Shaft rotational speed = 2750 RPM - Shaft input horsepower = 65 HP COMPONENT DATA: condition. This will result in the best belt life and lowest shaft loads. However, this ideal tension is hard to determine and difficult to maintain. This section provides a practical method for calculating and measuring belt static tensions based on drive parameters and design power. An alternate method is provided in Section 3.2 for the case Design of Propeller Shaft (dp) Since the propeller shaft is subjected to both bending moment due to propeller weight and twisting moment diameter of propeller shaft dp = 25% extra then the designed by pure torsion. dp = 1.25 x 400.135 dp = 500 mm Design of Intermediate Shaft (d) The intermediate shaft is subjected to bending 1)MPa (= N/mm2) b Width of square groove (circlip) mm d Minimum shaft diameter at notch mm diInner diameter of shaft at notch mm dhDiameter of hole mm D Bigger diameter in way of not
