CUTTING-EDGE RESEARCH BY KONGSBERG AND ATA GEARS MAKES NEW DISCOVERIES ABOUT TFF
André Böhme has a mission: fighting TFF. Subsurface fatique, TIFF or TFF, is causing several unforeseen gear failures and thruster replacements every year. It is the predominant failure mode on bevel gears used in azimuth thrusters onboard state-of-the-art vessels. And fatigue or overload can destroy any gear. For good reason, there is very innovative, comprehensive
WHEN SEW-EURODRIVE AND ATA GEARS COMBINE THEIR EXPERIENCE, WONDERFUL THINGS HAPPEN
There are two SEW-EURODRIVE companies in Finland, SEW Industrial Gears in Karkkila and SEW-EURODRIVE in Hollola. Both are ATA Gears’ customers: The Karkkila unit has many of its bevel gear pairs manufactured by ATA Gears for use in the new gear units it itself manufactures, while the Hollola unit sources parts and components for the
TAKE THE TRAM!
The tram is the way to easier and cleaner everyday living. Ten purpose-built bridges and seven structures renovated for safe and smooth transport will soon enable 19 brand-new tramcars to glide along 15 kilometres of gleaming heavy-metal tramlines. Four years of construction work have kept section 1 of the Tampere tramway right on schedule ready

HOW TO GET IT RIGHT THE FIRST TIME – AND EVERY TIME
With gears over 3 metres in diameter Big gears almost always run vital processes, which are often also a company’s most expensive ones. In many cases the company may have no backup equipment and any breakage can easily cause long downtime, possibly even resulting in the company being unable to finish the job or continue
BEVEL GEAR QUALITY IS NOT GUESSWORK
The best raw materials, state-of-the-art design, engineering tools and know-how, in-house heat treatment, fine-machining and super-finishing: That’s what’s behind all ATA Gears’ solutions and deliveries. But even that is not all. You could almost say that it takes just about as many quality factors to make a bevel gear as that gear has teeth. A
CASE HARDENING – THE HEAT IS ON
Gears are expected to function reliably for years or even decades under extreme loads, so case hardening is one of the key development areas in this specific field of mechanical power transmission. That’s why ATA’s Gear Doctors are ceaselessly researching heat treatment and material science. Water jet cutting, sample cutting, grinding and polishing, adding to
