This paper presents a gear design optimization approach that was applied to reduce both tooth contact temperature and noise excitation of a high-speed spur gear pair running without lubricant. The optimum gear design search was done using...

A failure mode called“flank breakage" is increasingly observed in different applications of cylindrical and bevel gears. These breakages typically start from the active flank approximately in the middle of the active tooth height and propagate to the...

Most of the large open gear sets for mining industry are designed according to ANSI/AGMA 6014-A06 and ANSI/AGMA 2001-D04. Basically, customer specifications and AGMA service factor ratings both depend on design of the pinion (including material selection...

For gears larger than 3 m (10 feet) in diameter, construction of gear blanks tend to be divided into cast steel, ductile iron, and forged rim welded web structures for use in cylindrical grinding mills and kilns....

In this paper, a manufacturing method of the pinion member of large-sized skew bevel gears using a multi-axis control and multi-tasking machine tool respecting an existing gear member is proposed. First, the tooth surface forms of skew...

Depending on annual production volumes, batch sizes and workpiece geometry several gear manufacturing technologies are used for industrial gear production. Most applicated is the hobbing process, followed by broaching, shaping, sintering and rolling processes. Upcoming gear manufacturing...

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...
