Gear Noise – Challenge and Success Based on Optimized GearGeometries Dr. Franz Hoppe and Dr. Burkhard Pinnekamp, Renk AG Forgear transmissions different levels of requirements with regard tonoise excitation have to be matched. Industrial applications forconveyor belts or cement mills are without doubt much lesssensitive with respect to noise emission than militaryapplications, e.g. for navy ship propulsion. However, also forindustrial applications the air borne and structure borne noisebehavior more and more becomes an important feature. RENK has beendeveloping optimum gear units for all applications with atransmitted power level ranging up to 145 MW. This paper describesrequirements and solutions with regard to noise behavior focusingon examples taken from navy applications and wind turbine geartransmissions. The individual approaches have to be a suit-ablecompromise to meet the challenge of noise requirement and costoptimization without any restriction on gear load carryingcapacity. Therefore, there is no general but individual solutionfor optimum design. The paper comprises basic considerations withregard to gear noise, noise requirements and measurements at shopand field tests in comparison to gear geometry and calculationresults.
