Introduction to Gears

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.

High-Performance Differentials, Axles, & Drivelines

Every automobile has a differential and most have axles, yet the exact function of these is not common knowledge. This comprehensive seminar introduces participants to the function and interfaces of axles and their individual components. As we modify cars for street performance or all out race applications, it is important to know the trade-offs in the drivetrain system. The theory and practice of axle systems is introduced along with a hands-on style approach to repairing and modifying axles for high performance applications. For this hands-on approach, actual hardware will be reviewed in an informal setting.

Threaded Fasteners for Automotive Uses

Fastener experts believe that upwards of 95% of all fastener failures are the result of either the wrong fastener for the job or improper installation. Whether this shocking figure is accurate or not, it is irrefutable that threaded fasteners are poorly misunderstood by many in both the fastener and user communities. In October 1990 the USS Iwo Jima suffered a catastrophic steam valve accident minutes after leaving port following repairs to its steam plant. In one of the single most deadly events of Operation Desert Storm, ten of the eleven crewmen present in the engine compartment would lose their lives.

Fundamentals of Modern Vehicle Transmissions

Starting with a look at the transmission's primary function -- to couple the engine to the driveline and provide torque ratios between the two -- this updated and expanded seminar covers the latest transmission systems designed to achieve the most efficient engine operation. Current designs, the components and sub-systems used, their functional modes, how they operate, and the inter-relationships will be discussed. A manual transmission display will be used to explain ratios and how they function within the driveline.

Statistical Gear Optimization Method Against Whine Noise

In industrial automotive transmissions, several noises can't be avoided such as gear rattle and gear whine noises. Indeed they result from the choice of gear technology. They just can be reduced by an appropriate design. It is widely acknowledged that gear whine noise is mainly due to transmission error, which depends on many parameters such as driveshaft deflection, gear stiffness and operating torque. All these parameters are not necessarily well-known, which may sometimes result in the choice of a gear geometry that doesn't minimize transmission error. That can lead to customer claims once the vehicle is manufactured. To cope with whine noise customer claims, we investigated a statistical gear optimization method. The principle is to use whine measurement data base on benches to find the best geometry against whine noise after a statistical treatment. The main advantage is that it is not necessary to know precisely all the parameters involved in whine noise.

Multi-Pass Method for Evaluating Filtration Performance of Fine Lube Filter Elements Utilized in Aerospace Power and Propulsion Lubrication Systems

This SAE Aerospace Recommended Practice (ARP) describes the multi-pass method for evaluating the filtration performance of fine lube filter elements, commonly utilized in aerospace power and propulsion lubrication systems: gas turbine engines, auxiliary power units (APUs), helicopter transmissions, constant speed drives (CSDs), and integrated drive generators (IDGs).

Front and Rear Power Take-Off for Agricultural Tractors

This SAE Standard establishes the specifications and dimensions that are essential in order that 540 r/min and 1000 r/min power take-off-driven machines may be operated with any make of tractor equipped with the corresponding power take-off drive.
