The sound quality of technical products is an increasingly important quality criterion and has a significant influence on the product acceptance. But sound quality does not only depend on the physical attributes of the sound signal. It...

Modern Navy and Coast Guard Vessels usually have combined propulsion systems using gas turbines, diesel engines and electric motors as main propulsors. Desired operating profiles demand for individual optimization of the gear propulsion system with respect to...

Demand for higher relibilit, robustness and performance in epicyclical gearboxes have led SKF to develop Design for Six Sigma (DFSS) based simulation tools and methods. This paper will ilustrate the advantages of using simulation driven design in...

This computational work investigates planetary gear load sharing of three-mount suspension wind turbine gearboxes. A three-dimensional multibody dynamic model is established, addressing gravity, bending moments, fluctuating mesh stiffness, nonlinear tooth contact, and bearing clearance. A flexible main...

Global energy demand is predicted to be about 30 percent higher in 2040 compared to 2010 (1). Energy demand growth will slow as economies mature, population growth moderates and efficiency gains accelerate. This paper will focus on...

The application of cylindrical roller bearings (CRB) is widespread in mechanical engineering. CRB can carry comparatively high loads and are usable in high speed ranges. These bearings have been proven to be variably applicable and economic. With...

In the late 1970's a balancing machine salesman visited a customer's plant who had just received a new balancer from the salesman's competitor. The plant manager said they were very happy with their automatic balancing machine and...

This paper will review the significant manufacturing and processing benefits that arise from this new class of secondary-hardening steels, and analyze the potential implications and opportunities. C61 and C64 were computationally designed to take advantage of high-temperature,...

A detailed evaluation of furnace heating systems will be performed. Topics of discussion will include application guidelines for both gas fired and electrically heated furnaces. Heating system selection will consider operating temperature, processing atmosphere and heating method...

Induction hardening is widely used in both the automotive and aerospace gear industries to minimize heat treat distortion and obtain favorable compressive residual stresses for improved fatigue performance. The heating process during induction hardening has a significant...
