Slater Tools

A major player in the screw machine tooling industry in the 1960s, Slater Tools later patented the first rotary broach tool holder system and has since become synonymous with rotary broaching.

Formed in 1951, Slater Tools began as a modest machine shop in Warren, MI and moved to Clinton Township in the 1990s, where they’ve been ever since. Today the company’s rotary broaching and screw machine tools operate throughout North America and around the globe on CNC lathes, mills, and Swiss screw machines. Slater’s innovations, as […]

Gear Lubrication-Gear Protection Also At Low Oil Temperature

It has been shown that the advanced additive technologies used in today’s high-performance gear oils are capable of inducing the required reactions on the surfaces of gears and bearings also at 40°C, thus providing reliable damage protection even under these operating conditions.

In practice, industrial gears are often operated with lower oil temperatures than would normally be generated in a fully-loaded gearbox. Lower temperatures prevail, for instance, while a gearbox is being taken back into use after prolonged standstill, i.e. during the time it takes for the oil to heat up from ambient temperature to service temperature.

Precision Broaching of Gears Large and Small

The proper use of precision broaches is just as important as material choice and design specifications. Learning the proper way to broach will make all the difference.

The broaching of precision gears will always start with a designed broach to match the specification of the part print. The broach designer will evaluate all the facts such as material, wall thickness, and, most importantly, the class of fit required on the gear. However, even with all the expert knowledge the designer puts into […]

The Effect of the Surface Roughness Profile on Micropitting

The roughness profile of metal-to-metal contacting parts is one of the most important characteristics in making mechanical systems more durable and energy efficient.

A wide choice of surface roughness parameters is available to characterize components such as gears or bearings, with the goal of predicting the performance of such metal-to-metal contacting parts. Commonly in industry, the roughness average (Ra) or the mean peak-to-valley height (Rz (DIN)) is chosen to calculate the specific film thickness ratio for both superfinished […]

Form and Position Measurement Advancement Through Measurement Technology

The transmission is one of the key components on through which, thanks to the clever design of all components, the degree of efficiency, wear, and noise emissions can be optimized.

This industry has a tailwind; the wind power industry is growing at a rapid pace. The reasons for this are many. Ambitious climate targets, necessary CO2 emission reductions, and the ongoing debate about atomic energy are ensuring a boom in the industry, thus also a flurry of activity in terms of technological advancement. Modern measurement […]

Powder Metal Gears, Part VI

Another unanswered question with this technology is: What happens to the pores? Are they flattened into cracks after the process? There are hypotheses about cold welding and healing in heat treatment of the flattened pores, but none have been proven.

The heat treatment issue discussed in previous columns remains for the rollforming as well; low-pressure carburization helps, due to a better process when introducing the carbon-rich atmosphere. Yet another process is the Densiform process from PMG. Their website (www.pmgsinter.com) has some good information on this technology, and there are also patents protecting it. I will […]

There are four standardized AGMA systems of bevel gear tooth proportions: 20° straight bevel, Zerol bevel, spiral bevel, and hypoid – and some special modified forms

In this month’s edition of Tooth Tips, let’s take a look at bevel gears at angles other than 90º. When the sine of the angle between the shafts is divided by the sum, the tangent of the pitch-cone angle can be calculated: The sum = divide number of pinion teeth by number of gear teeth […]

Finding the perfect heat treat

Debate rages on perfect heat-treating for gears that are smaller, thinner, finer pitch, with residual stress from machining, and the ability to satisfy the cost constraints of heat-treat.

Three on the tree; four-on-the-floor; four speed automatic; five speed manual; six speed automatic; six speed manual; seven, eight, and nine speed automatic…where will the drive for the maximum number gears in an automobile transmission end? The drive for fuel economy seems to have no limits. Is there a 16-speed transmission on the drawing board […]

Q&A with Bill Gay

Technical Service Manager, Bel-Ray Lubricants

What’s so important about choosing the right lubricant for gear production? With the right lubricant, it all comes down to contamination elimination, which extends the life of the gears. Contamination comes in through various mediums, such as seals in different areas, dust, and water. The size and hardness of particles really affects the type of […]
