NAMCO Machine and Gear Works, Ltd.

This family-operated Edmonton gear company’s rich history is evident in its work ethic and substantial product line.

Bernard Vukovic’s parents, Ivan and Kate Vukovic, emigrated from Croatia and lived in Germany for 5½ years, where his father learned the machinist trade. While in Germany, his parents were committed to finding a place where they could secure employment and, more importantly, citizenship. When the opportunity to move to Canada presented itself, they embarked […]

Gearing Up to a Better Chamfering and Deburring Process

The chamfering and deburring of gears is often an undervalued process in gear production. However, it has a great influence on the usage characteristics of the work piece.

As with any machining process, the manufacturing of gears by hobbing or shaping results in burrs on the front edge. These burrs must be removed because they are hazardous to machines, tools, operators, or the process in general. This chamfer and deburring process should be carefully considered at the beginning of a new project for […]

Go Big, Go Indexable

Advanced carbide insert technology meshes with increased demand for large gears.

Indexable carbide inserted tooling continues to push large gear productivity. As manufacturers of big gears are further pressured by increased production demands from key industries, including energy, they strive to meet such requirements through faster machining speeds and feeds, yet still maintain high levels of quality. Gear shops have used indexable carbide inserted cutting tools […]

Cost Reduction Using Powder Metal for Pump and Metering Gears

The powder metal process provides engineered components in just about every industry today, especially producing high quality gears of all types. The following article outlines just one application segment: precision pump and metering gears from powder metal.

Powder Metal (PM) gears are used in pumps across a wide spectrum of industries. These include lube pumps for power transmissions in automobiles and heavy trucks, off-road and agricultural vehicles, the food industry, hydraulic lifts, metering/dosing fluids, and moving chemicals.  (see Figure 1). PM gears are used in these industries to lower cost without sacrificing […]

Squeezing Productivity Out of Gear Milling Operations

When we talk about the broad and common operation of slot milling, the name of the game is chip thinning.

Gashing in gear milling applications is basically a slotting operation. Whether it is a gear tool such as a CoroMill® 170 or a standard slotting cutter such as the CoroMill® 331, the aim is to apply the correct feed rate to take advantage of chip thinning. When a programmer or operator fails to take chip […]

Q&A with Scott Richards

Vice President, James Engineering

James Engineering specializes in deburring machines. A number of gear manufacturers are still hand deburring their products, aren’t they? I’m working with one right now—a leading forklift manufacturer, surprisingly. It’s incredibly time consuming. We’re seeing people with two or three shifts of people working five days a week just hand deburring parts. Why are people […]

Why is the Center in Tension?

To better understand why the center is in tension, one can do simple volumetric calculations of theoretical consecutive ring segments within a round cross section.

Consider that each ring segment has the same volumetric expansion. Next, take the mid-wall circumference and multiply that by the volumetric expansion resulting from quenching. While maintaining a constant before and after wall thickness, calculate the new OD and ID dimensions (Table 1). The new OD and ID should mismatch from each ring segment to […]

All-Steel Hypoid Gears

The all-steel hypoid gear technology is recognized for high efficiency, durability, and quiet operation.

In comparison, worm gear drives use softer, bronze gearing, which shortens service life, and they operate at efficiencies that decline as ratio increases. Hypoid-gearing efficiency stays relatively flat and begins to show significant efficiency advantages for ratios greater than 30:1 ratio. For these reasons, companies choosing hypoid gearing technology for their application usually see significant […]

A look at controlled rotation systems

Driverless technology, in its fundamental form, already exists in academia and private consortiums.

Driverless technology, in its fundamental form, already exists in academia and private consortiums. The basic components are here: GPS can track and sense a car’s position anywhere, along with its location, speed, direction, and altitude. OnStar can turn the car’s engine off and control most computer-controlled functions. Sensors such as infrared and radar can detect […]
