FEATURES

Company Profile: Milwaukee Gear

Milwaukee Gear may be old, but they keep their edge sharp by investing regularly in the latest technology. Plus, they’ve got some truly gifted machinists.

According to Joe Leone, manger for quality control/gear grind, Milwaukee Gear has been in operation for 94 years and was founded by Emil Borisch and Walter Kohls. The two men started the company in a small, one-story, brick building in downtown Milwaukee, and served as the company’s salesmen, machinists, order clerks, and product inspectors. Milwaukee […]

Precision Planetary Servo Gearheads

Because of their versatility, as well as their ability to speed-up and automate the complex motion sequences, today’s automated computer-controlled machineries, intelligent robots, and majority of the modern automated equipment’s use highly dynamic servo-motors.

Precision planetary gearheads are frequently used in conjunction with such servo motors in order to: balance inertial loading conditions seen during frequent speed cycling sequences, decrease the motor speed, boost the torque, and at the same time, provide a robust mechanical interface for pulleys, cams, drums, and other mechanical transmission components. Actually the servo-motor and […]

Micro Skiving: Precision Finishing of Hardened Small Diameter Fine Module/Pitch Gears, Splines, and Serrations

On their AF100 AF101 and new AF110 CNC high speed gear hobbing machining centers, Affolter Technologies S.A. offers the option of -Skiving (micro Skiving).

The skiving process, which means “to slice,” with respect to cylindrical spur and helical gears and some limited spline hobbing applications, was traditionally used to re-hob or correct a distorted tooth profile. In the early days, this method served as an economical alternative to expensive generative threaded wheel grinding or profile form grinding process applications. […]

From Many, One

Composite bronze worm gear blank technology is a reliable, off-the-shelf cost savings solution that can be quickly evaluated and adopted.

In June 2013, a $1B industrial equipment manufacturer was on a cost savings mission for an assembled worm gear that was ripe for simplification. The assembled worm gear design and eight design variations thereof are found in the majority of the 10,000–12,000 units of new industrial equipment manufactured every year at their factory in the […]

Hobbing Large Gears with Custom Workholding Let ROI Blossom

While often overlooked, workholding can play a vital role for customers interested in maximizing production performance.

Savvy gear manufacturers not only look at new machines and cutting tools but also focus on and invest in their workholding. Utilizing application-specific workholding for large gears, like the modular pedestal type fixture described in this article, can multiply their total project return on investment significantly. When changing from a traditional style of fixture to […]

Add Big Gear Sets to the Multi-Tasking List

With a standard, full 5-axis multi-tasking machine, shops can cost-effectively process all of their larger, low-volume parts, including the occasional spiral bevel gear sets.

Many shops increasingly incorporate full 5-axis multi-tasking machine tool technology because it allows them to handle any kind of part that comes through the door, with one type of machine, in single setups to increase productivity. But rarely, if ever, do these shops realize that large spiral bevel gear sets are also among that wide […]

Complex Form Grinding Technology for Advanced Abrasive Technology

The attraction of dressable CBN wheels over single layer CBN wheels, for gear grinding especially, is the ability to make profile corrections.

The grinding industry is seeing major advances in abrasive technology and in the machine tool capabilities to enable this technology to be fully utilized. One such area for the development of these systems is in the precision form grinding of gears, ballscrews, and micro threads using the conventional, engineered, “ceramic” superabrasive grains, and novel bond […]

Determining Transformation Products

The cooling rate and chemistry of a steel part dictates what type of transformation products form.

Transformational stresses arise from the volumetric expansion of the Face Centered Cubic (FCC) crystal structure to Body Centered Cubic/Tetragonal (BCC/BCT). The degree of volumetric expansion is dependent upon alloy percent, cooling rate, and microstructure formed (Table 1 and Chart 1). Martensite, bainite, and pearlite have different volumetric expansions for the same carbon content. Lower transformation […]

Right-Angle Gearboxes Using Hypoid Gears

By employing a hypoid gear, engineers have created a right-angle gearbox that offers high reduction, high efficiency, and compactness.

Still using a worm gear and trying to improve the overall efficiency of your system? Purchasing a high efficiency NEMA premium motor may improve efficiency only marginally if you pair it with an inefficient gearbox. The motor is only half the equation—you need to also improve the gearbox efficiency if you want to improve your […]

One of the most critical functions of heat treating doesn’t involve heat at all

In higher-alloy material, such as precipitation hardening steels (PH), hardening requires a two-step application—one of removing heat by quenching followed by adding heat to produce aging by the precipitation of complex carbides, supplementing the wear resistance of the martensite. If the quench in either case of ferrous material and PH is not fast enough, carbon/iron […]
