Electromagnetic contactless torque transducer: torque measurement and Shaft impediment approach
2019Co-Authors: Mohammed Ataur Rahman, A. K. M. Mohiuddin, Badrul DaudAbstract:The torque transducer is important to measure the torque on a rotating power Transmission system such as engine crankShaft, Transmission, motor Shaft, and bicycle crank. Static torque is relatively easy to measure but dynamic torque is difficult to measure, since it requires transferring some torsional effect in terms of electric signal or magnetic inductive voltage. The several torque transducers has been made with slip ring and metallic resistance strain gauges to measure the dynamic torque of the power Transmission Shaft. However, the slip ring method brushes are prone to wear and tear and need to be replaced frequently while the strain gauge chemical properties is disturbed due to heat and provided the significant error of the signal output which emphasis this study to develop an electromagnetic non-contact (EMNC) torque transducer to measure the dynamic torque of the power Transmission Shaft. The EMNC torque transducer has been made from this study with a permanent magnet and two cylindrical coils. The first coil serves as the electromagnet, which causes the force (attractive) and second coil gets the voltage induction due to the changing of the magnetic field. The measured voltage of the second coil represents the torque applied on the Shaft.

REMOVABLE AUGER FOR 3D PRINTING TO ALLOW A DEEP CLEAN FOR CHANGING THE PRINTING MATERIAL
Technical Disclosure Commons, 2019Co-Authors: Hp IncAbstract:This disclosure relates to the field of 3D printing machines using plastic or metallic powder to build parts, like powder bed fusion or binder jetting processes. The automation of these processes requires moving the powder from the supplies to the printable area. One of the most reliable ways to convey or lift powder is using an Archimedes screw that is located inside a tube. A problem occurs when the Archimedes screw should be cleaned, for example, for changing the printing material. The Archimedes screw is usually long and should be removed through one of the sides of the tube. On the other side there’s the Transmission Shaft that provides torque to the Archimedes screw, that difficult the extraction of the Archimedes screw

Research on forging forming force in the composite technology of cross wedge rolling (CWR) and forging for universal joint fork
Croatian Metallurgical Society (CMS), 2019Co-Authors: Xu J. Y., Su . S., Li N.Abstract:In this paper，the forging process of universal joint fork of automobile Transmission Shaft is simulated and the change of forming force of die forging is studied on the basis of the blank produced by cross wedge rolling (CWR). Temperature / T , friction factor / c and falling speed of upper die / V are the main process parameters affecting the forging forming force / F of universal joint fork. The effects of temperature, friction factor and speed on the forming force were studied respectively by single factor method. The results show that the lower the temperature, the greater the friction factor, the slower the speed, the greater the forming force, the more difficult for forming. The orthogonal test is designed and it obtained the order of process parameters affecting the forming force of die forging that is T > c > V and the best combination of process that the temperature is 1 100 °C the friction factor is 0,2 and speed of upper die is 150 mm/s
