Project title: Experiment and improvement on noise reduction and efficiency of gears in diesel engine
Thesis:
In most machines, the major requirements for gear transmission are low sound excitation character, a high-level load carrying capability and generally high efficiency, which is more vital with increased environmental awareness. This paper discusses and analyzes two main elements gear system efficiency improvement and sound excitation. The main reason in noise reduction at gear system is given. Recommendations for reduction in sound excitation and looses in gear mesh have been given.
Abstract
Noise from heavy machinery that depends on gears such as heavy tracks, heavy-duty generators, has become a significant environmental concern. The levels of noise from the gearbox can be very disturbing to the personnel operating the machine and the general population. Gear noise is becoming an important factor to put into consideration during the design of gears, especially due to the allowable noise levels that machines should emit for environmental safety (Society of Automotive Engineers 56). Various factors play an integral role towards the generation of noise by such machineries. Gear dynamics and noise are the most underdeveloped areas in the studies involving gear design; this has caught the attention of many current studies. The kinematic design and geometric design, the mathematical modeling of gearboxes, and vibration analysis of gears are the key principles in attempting to model a good gear system. It is becoming necessary to put into consideration the vibration characteristics of gear systems and the meshing transfer error fluctuation in order to help in the reduction of noise during gear transmission. So far, research studies reveal that vibration characteristics of gear systems include the effect that the gear train structures have in the levels of rigidity of the significant meshing points, rib arrangements
