Gear Production is a new supplement to both Modern Machine Shop and Automotive Design & Production magazines. View a digital version of the supplement here. The Gear Production Zone covers all phases of gear manufacturing. That includes gear generation on traditional gear cutting and finishing equipment. Also covered is cutting gears on machining centers and other non-traditional equipment.
To help global automakers achieve greater fuel efficiency, ZF Friedrichshafen AG is developing transmissions that are deploying an increasing number of gears.
They needed precision gears of a variety of sizes and configurations, so what did Liebherr do more than 60 years ago? It designed, engineered and built its own gear-making equipment, which became one of its businesses. And yes, it still produces gears for its own requirements.
Advances in machine design, cutting tools and process simulation software have finally converged, making it possible for Gleason to offer a practical and highly productive power skiving solution. Here’s how the new process can revolutionize the way internal gears are produced.
Moving small- to medium-batch production from outsourced, dedicated hobbing operations to in-house, CNC multitasking machines helps job shops achieve quick turnarounds and flexibility in supplying splines for the heavy-vehicle industry. Inserted disc cutters make this transition possible.
The CoroMill 177 tangentially mounted hob from Sandvik Coromant is said to increase productivity and tool life in gear wheel machining operations.
“In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy.
At the Geneva Motor Show, Jeep introduced the Renegade—a small SUV that, unlike many other small SUVs, has a 4x4 system that is said to provide off-road capability (there is Jeep Active Drive, a full-time 4x4 system, and Jeep Active drive low, a 4x4 system that offers a 20:1 crawl ratio; there is a disconnecting real axle and power-take-off-unit to provide fuel efficiency when 4x4 isn’t required), a vehicle based off the “small-wide architecture” that’s used for the Fiat 500L, but engineered so that there is the aforementioned off-road capability (which also includes fully independent suspension and the ability to have up to 8.1 in. of wheel articulation and 8.7 in. of ground clearance); a vehicle that Jeep plans to sell in multiple global markets, so it is offering it with 16 different powertrain options, gasoline and diesel, manual and dual dry-clutch automatic, as well as the segment’s first nine-speed automatic; a Jeep that is being built in a Fiat plant in Melfi, Italy—it brought over a group of journalists, including Frank Marcus, technical director at Motor Trend.
When Lamborghini went into the Geneva Show for the mass public unveiling of its Gallardo successor, the Huracán, the company said that through a series of private showings, it had already booked orders for 700 units.
