Drivetrain Integration

Flender unveils the next generation of wind gearboxes

Logistics, transportation and maintenance have always been critical challenges in wind turbines. There’s truth to the notion that large components can cause bigger headaches on their massive size and scope alone. A smaller, compact drive solution can help eliminate today’s renewable energy challenges while reducing costs.

A Review on Gear Transmission Error

This paper will review the development process, current research status, characteristics, functions, and measurement methods of TE. It will analyze the difficulties and core issues existing in the basic theory of TE, clarify the limitations and deficiencies of TE, and explore ways to overcome the shortcomings of TE.

Prospects of Asymmetric Gears in EV Gearbox

The paper examines how optimizing asymmetric gear tooth geometry through Direct Gear Design can improve load capacity, efficiency, and compactness in EV gearboxes, surpassing the performance limits of conventional symmetric gears.

.

Interchangeability of Gears

An excerpt from Gear Technology Solutions by Dr. Hermann J. Stadtfeld covering when and how individual bevel gear members can be replaced during gearbox service without changing the mating gear.

The Intrinsic Pitch Cones in Hypoid Gears

A method to calculate pitch cones for hypoid gears using macrogeometry parameters—similar to non-offset bevel gears—while accounting for the added complexity of hypoid offset, tooling, and cutting technology is explored in this paper.

Design

For cylindrical gears, speed-increasing transmission stages are well known, and regarding profile shift, preferred pressure angles, and helix angles a set of rules applies, which is not much different from the rules for speed reducers. It is important to acknowledge that basically, a speed increaser has to be designed just like a speed reducer, but then the gear with the lower number of teeth is the output. Of course, the torque and the speed of the gear with the lower number of teeth (output) and the gear with the higher number of teeth (input) must be the same as if this transmission was used as a speed reducer. In the case of straight bevel gears, spiral bevel gears, and hypoid gears the same rules apply with some additions. Spiral bevel gears have many applications as speed increasers.  

Grinding

Cylindrical grinding is an essential machining process in precision manufacturing, ensuring that components meet stringent tolerances with superior surface finishes. Optimizing this process involves a strategic approach to wheel selection, process automation, in-process measurement and machine maintenance. This article explores key technical factors that influence the efficiency and accuracy of cylindrical grinding operations.

NVH

The arrival of Gleason’s Hard Finishing Cell (HFC) in 2018 represented a paradigm shift in the way automotive transmission gears and gears for e-drives, could be produced in high volumes. Now, for the first time, 100 percent inspection of every gear, and every gear tooth was possible in-process, without impacting the high speeds at which these gears need to be hard finished. Identifying, and correcting for, conditions that create unacceptable noise behavior in these gears, on the fly, was finally a reality too.

Heat Treating

Furnaces North America 2022 (FNA 2022), presented by the Metal Treating Institute (MTI), in partnership with its media partner, Heat Treat Today, is the heat-treating industry’s go-to event every other year. FNA 2022 attracted attendees from across North America, including Fortune 500 companies. For three days attendees took part in networking, connections, and learning about the vast changes taking place in emerging technologies, industry trends, and advances in equipment.
