Abstract:

AIRCRAFT GAS TURBINE ENGINES OPERATE AT SPEEDS RANGING FROM 10,000 TO 30,000 RPM. TO HARNESS THIS POWER AND TO OPERATE AT DESIRED OUTPUT SPEEDS, THE INDUSTRY RELIES ON THE USE OF HIGH SPEED TRANSMISSION SYSTEMS. AS POWERS AND SPEEDS OF THEENGINES ARE INCREASING, THE GEAR INDUSTRY HAS RESPONDED TO TO THESES NEW REQUIREMENTS WITH HIGHER QUALITY HARDWEAR, CLEANER STEELS, AND IMPROVED MANUFACTURING TECHNIQUES. THIS PROJECT STUDIES THE APPLICABILITY OF SINGLE AND DOUBLE HELICAL GEARS AS POWER TRANSMISSION COMPONENTS TO COMPLEMENTTHE PERFORMANCE OF THE NEW HIGH SPEED GAS TURBINE ENGINES. THE PROJECT LOOKS INTO USING HELICAL GEARS TO MINIMIZE THE PROBLEMS OF GEAR DYNAMICS, GEAR NOISE, AND GEAR VIBRATIONS. AS HELICAL GEARS SHARE TRANSMITTED LOAD OVER MANY TEETH, THEY ARE LESS NOISY THAN THE TRADITIONAL AIRCRAFT SPUR GEARS, WHICH SHARE LOAD BETWEEN TWO TEETH, AS POWER AND SPEED REQUIRED INCREASE. IN ADDITION, HELICAL GEARS ARE LESS DIFFICULT TO MANUFACTURE THAN SPUR GEARS.
