Striving for High Load Capacity and Low Noise Excitation in Gear Design

The conflict between flank modifications, with a focus on load capacity, is documented.

Many dimensions of the gears and the toothing are determined that have significant influence on load capacity and noise excitation. Though a detailed analysis is not in focus yet, the final goal of optimization has to be kept in mind. The last step of optimization usually is an adequate design of flank modifications. The possibility […]

Ductile Iron for Open Gearing – A Current Perspective

While steel is well known as a gearing material, for both its strengths and its weaknesses, ductile iron remains a lesser-known commodity even after several decades of use.

Gears made for applications in the mining and cement industries cover a wide range in terms of size and transmitted power: from Ø1 m to Ø14m, from 500 kW to 17 000 kW (dual pinion drive). To select a material to suit all these different applications is somewhat more complicated today than perhaps 50 years […]

Contact Analysis for Planets in KISSsoft

A precise analysis of the contact ratios in the meshing of gears is essential, whether you are designing new gears or assessing existing gear units.

KISSsoft’s contact analysis software is widely used because it calculates a wide variety of characteristics of interest for gears that are under load. These include: • The normal force that occurs during meshing; • The actual path of contact under load; • The transmission error, stress curves, flash temperature, specific sliding, power loss, heat generation, […]

Considering As-Heat Treated Grain Size

The as-heat treated grain size should be specified on a per heat treat lot basis for any gear forging material supplied in the final heat treated condition.

When reviewing and working to customer steel specifications, it seems to me that one of the most misused and misunderstood gear material requirements is the grain size requirement. A common grain size requirement I see is, “The grain size shall be 5 or finer when tested in accordance with (grain size standard)” with no additional […]

Pitch and Pressure-Angle Changes

The most frequent use of pitch and pressure-angle changes in the cutter is to increase the root radius in small numbers of teeth.

The engineer has the responsibility for the design of an involute gear set, and the tools that are used to cut the teeth in the gear blanks. If general, if you scan down the summary sheet, the diametral pitch (DP), pressure angle (PA) and base pitch (BP) are the same on the information sheet for […]

From smaller cold-formed steel, gears can be cold pressed into the final shape and size, teeth and all

All gears begin their lives as a forging, casting, hot-rolled bar, billet, powder metal, and, most recently, directly from 3D printing (additive manufacturing). Depending on the application, there then may be subsequent operations such as cold forming, instead of machining, to create the final shape. Most gear applications require a strengthening process after final machining […]

Trend Talks: Tim Byrd

All of the advantages of CNC, coupled with skilled operators who know what they’re making and know how to take care of problems, are putting the gear industry way ahead of the game.

I’m at the AGMA Basic Gear Training class in Chicago, talking to Robert Hamilton of Hamilton’s Industrial Machine Shop, located in Kingston, Jamaica. We’re making small talk, admiring the various machinery on the shop floor. “It’s true, computer numerical control (CNC) machinery in gear production is very powerful,” he says. “But it doesn't give you […]
