Training / Education Classroom Seminars
This seminar is designed to provide gear novices with a general understanding of gear nomenclature, geometry, and arrangements. Starting with the basic definition of gears, conjugate motion and the "Laws of Gearing", you will gain a solid understanding of gearing and the fundamentals of rotary motion transfer through gear-trains. Gear classifications, tooth forms and geometry, and very high-level application considerations, manufacturing processes, and inspection techniques will be covered. Attendees will receive a copy of the book, Gear Design Simplified, by Franklin D. Jones & Henry H. Ryffel.

Scuffing is an instantaneous gear failure, where flanks are welded together under pressure and temperature at high speed conditions. This is one of the common failure modes in manual transmission. Fig: Picture of scuffing near the gear tip High contact pressures are often experienced in high density power transfer gears at the tip and the root regions. These higher pressures coupled with higher sliding velocities and frictional heat generation makes the tip and root regions in the gear susceptible to scuffing. Gear geometry, operating speed, gear material composition, surface roughness and lubricant properties influence scuffing. A balanced gear tooth design with lower sliding velocities is often chosen as an approach to avoid scuffing. However, in the current scenarios of transmissions with high power density requirements achieving a balanced gear tooth design is seldom. Lubricants with higher viscosity avoid scuffing but has adverse effects on the transmission efficiency.

Abstract Using the PULSE platform for vibration analysis, which has been developed as an advanced solution for vibration measurements, the Robust Diagnostic Concept (RDC) was elaborated. The PULSE setup is designed to aid in fault diagnosis of a vehicle gearbox - the main part of a vehicle powertrain. Time Domain, Continuous Wavelet Transformation Technique (CWT), FFT and order analysis measurements are used for detection of an artificial pitting defect in a gear by tracking the gearbox response at accelerated speed and different loads. The test stand is equipped with three dynamometers; the input dynamometer serves as the internal combustion engine, the output dynamometers introduce the load on the flanges of the output joint shafts. The pitting defect is manufactured on the tooth side of the fifth speed gear on the intermediate shaft. The effect of temperature on the vibration measurements was also investigated to study its impact on the fault diagnosis.

Predicting the temperature distribution within a gearbox under operating conditions is a challenging task. This is due to the unsteady multiphase flow of the oil, local heat generation sources between the intermeshing gears and within the bearing, and the complex external airflow pattern surrounding the casing. Geometrical details within the gearbox, for example small gaps and features, as well as detailed cooling fins structure sounding the casing add to the modeling challenges. Complexities also arise due to the drastically different time scales representing the highly transient flow within the gearbox and the near steady external airflow removing that thermal load. For example, the gearbox needs minutes to reach its steady state temperature which represents tens of thousands of revolutions of the gears. The current work represents a methodology for modeling this multi-scale problem. A generic four-speed gearbox is considered.

In order to improve fuel economy to meet future regulatory standards, many new features must be added to vehicle powertrains. One of these is Stop/Start (micro hybrid) technology; allowing engine stop when operation is not necessary such as idling during traffic stops. Stop/Start technology allows auto manufactures to meet increasingly difficult fuel economy standards. In automatic transmission vehicles, the transmission must remain able to quickly engage gear in order to allow quick response on engine restart.

Modern vehicles are becoming increasingly complex – partially due to the growing requirement of transmissions that need optimisation of the gearshift process – examples being automated conventional and automatic transmissions, as well as double clutch and continuous variable transmissions (CVT). This increasing variety of configurations leads to complex development scenarios, that can manifest themselves as problematic issues affecting sensitive shift procedures – for example, a down-shift manoeuvre, that needs to be calibrated to provide seamless transition between ratios To assist in solving these problems, AVL has developed a tool chain and methodology, using powerful system architecture, to reproduce measure and model the problematic symptoms. In a particular case, the coast down shift from 3 to 2, in an automatic transmission with a high number of gears.

As transmission development has rapidly increased in complexity, so too has the transmission control software. Due to these requirements, extensive testing and documentation along with quick and efficient development are required. FEV responds to these challenges by integrating a transmission software architecture with an automated verification and validation process. The FEV architecture breaks down the software and reduces complexity while making it testable and reusable The FEV software development process incorporates AUTOSAR standards and safety standards such as ISO26262 in a structure that aids in the reusability of functions and components, thereby reducing development and testing time. This modular architecture approach supports efficient and simplified unit level testing as well as expedient component level testing once all of the functions are integrated.

GKN Driveline has launched a unique transmission for hybrid vehicles. Developed in Japan, the transmission works in combination with an electric motor, generator and internal combustion engine to deliver greatly improved fuel efficiency, high performance and flexibility. The powertrain can switch from: - Pure EV with a top speed of 120kph to - Series Hybrid, supported by the ICE via Generator when SOC is below 30% and - Parallel Hybrid with direct ICE support on the front for best efficiency and maximum performance This flexibility provides unmatched performance with a range of 900km and a fuel consumption of as low as 123.9mpg(1,9l/100km). The Multi-Mode eTransmission is driving the front wheels and combines ICE, Generator and electric Motor in a way to provide either EV, parallel ore serial hybrid mode with smooth, comfortable transition, fully transparent to the driver. The layout combines an electric motor, a generator and ICE powertrain in one transmission.
