Company Profile: Robust Gear

Robust Gear has been manufacturing high quality custom precision gears for over 25 years, and they aren’t slowing down anytime soon.

Robust Gear was incorporated in August 1985, by Tarsem (Sem) Tak in the town of Oakville, Ontario. Tarsem‘s dream was to create a niche in the custom gear market that would be fulfilled and serviced by his company. By the time of his death in December 2012, Tarsem had built up a solid reputation of […]

Gear Resonance Analysis and Experimental Verification Using Rapid Prototyped Gears

Tests to reduce risk are used to build confidence in the design and analysis techniques before the final product reaches an aircraft.

Weight reduction is of great importance in the design of gearing for aerospace applications. Natural resonance responses of the gear head and shaft change in frequency and amplitude as weight is reduced for aerospace gears. Care should be taken to understand the gear resonance modes and compare the modes with operating speeds. Modes should be […]

Upgrading and Testing a 72,000 H.P. Gearbox

Transmitting 54 megawatts, or 72,000 horsepower, through one gear mesh at a pitch-line velocity of 29,000 feet per minute is not child’s play.

Another Day at the Gear Hospital Over the past 40 years, we have had many gearboxes come to our door that have had chronic, operational issues in need of remedial treatment. Sometimes, the fix is straightforward, and sometimes it’s pretty complex. Design Model This last year, The Gear Works became involved in a gearbox repair […]

UNIMILL: Prototype and Small Batch Bevel Gear Manufacturing

The UNIMILL method produces bevel gear geometries identical to those produced by face milling cutters.

Manufacturing of spiral bevel and hypoid gears can be conducted in several ways. The following methods are commonly known: • Face hobbing with a circular face cutter, which rotates while the work rotates in the opposite direction (continuous indexing). • Face hobbing with tapered hob (peripheral cutter), which rotates while the work rotates as well […]

A New Innovation in Spline Rolling Rack Tooling

The R/C Rack System is the first major innovation in spline rack tooling since the inception of the process 60 years ago.

The spline rolling process was invented by the Michigan Tool Company in 1954. The tools used for the process, commonly referred to as spline racks, are solid pieces of toothed tool steel designed in such a manner as to cold form the appropriate number of external involute spline teeth on a work piece, typically a […]

Manufacturing DIN 5481 Type Spline Serrations

DIN 5481 type spline serrations can be manufactured by milling cutter, hob, broach, and rolling.

This month, we will focus on calculating and sizing DIN 5481 type spline serrations for any application. The latest document is a 2009 update to the original 1956 standard. However, the document is not available in the U.S. due to publishing restrictions. As far as I know, it is only printed in German. Nevertheless, the […]

Tool Coatings and Dry Cutting

The high cost of dry cutting is offset by the higher cutting speeds it offers.

There has been a movement in recent years to dispense with the use of coolants in gear cutting. This has been normal practice in cutting cast iron but has been unachievable in the cutting of steel with “traditional” high speed steels. The advantages of dry cutting include: • coolant cost • cleaner environment • no […]

Metallurgical and heat-treat forensics play important part in determining how and why parts fail

Automobiles and airplanes have been in the news recently — GM cars for ignition recall issues and airplanes because of crashes due to weather, missiles, and undetermined reasons. No matter the case, metallurgical and heat treat forensics play an important role in determining what and how things happen. Cars and airplanes contain steel, cast and […]

Trend Talks: Tim Byrd

Gear Solutions speaks with a handful of industry experts about how precision technology has shaped their products and clientele.

With dazzlingly precise multi-axis machines, better technology is leading to better tools, design ideas, and better gears. It’s no surprise:  metallurgists have been thinking 20 years ahead since, well, forever. When they invent something that takes gear manufacturing to the next level, it opens up a market for more improvement. But I’ve been wondering lately […]
