In this paper, the models for different power loss sources in transmissions from literature are applied and compared, which form the two methods - ISO 14179-2 and the joint model to estimate the power losses in a transmission. A 2-speed transmission in an electric vehicle is used as a case study to compare the two methods and validate them with experimental data.

In the general context of the reduction of energy consumption and polluting emissions, gearbox efficiency has become a major issue.

Worm, bevel, and parallel shaft gear units were installed at two breweries to provide the necessary process control.

How one gearbox manufacturer took an existing design and transformed it to meet the needs of this demanding environment.

Despite the maturity of the machine tool industry, allowing for many advancements in engineering design over the span of decades, a machine is stil...

In this study, a finite volume CFD simulation model of a single-stage injection-lubricated test gearbox was applied to investigate its oil flow and no-load power loss. The results provide physically plausible information on the oil supply and its distribution.

Forget the IIoT and Industry 4.o buzzwords. We're not interested in 10 to 15 years down the road or what the factory of the future is going to look...

The proof of the reliability of a gear drive is now an additional requirement. In Europe, the acceptance authorities for wind turbines are requesting a system reliability proof from gearbox manufacturers. The AGMA committee reviewing the AGMA 6006 standard for wind turbines is considering adding a chapter about design for reliability. However, reliability considerations are not new; NASA, for example, was in the 1980s using reliability concepts for gear drives.
