Gear Design Relevant Cleanness Metrics

A method is presented to characterize premium quality clean steels using statistics of extreme values (SEV) and quantitative stereology. The data can be used to perform gear design relevant engineering analysis of the potential for a gear failure due to bending fatigue in the root or flank or rolling/sliding contact fatigue of the gear tooth face.

The “Metallurgical Specifications for Steel Gearing” information sheet (AGMA 923-B05) [1] details non-metallic inclusion limits to meet AGMA grade expectations for a range of gear metallurgical processing methods (case carburized, through hardened, etc.). These limits allow gear designers and producers to select material suppliers that will meet the minimum expectations for material fatigue performance, but […]

New Refinements to the Use of AGMA Load Reversal and Reliability Factors

This paper suggests two ways to calculate a load reversal factor that would be material-specific, based either on Modified Goodman or Gerber failure theories, and further provides a method of calculating the reliability factors that closely match the AGMA tables found in ANSI/AGMA 2101-D04.

The American Gear Manufacturers Association (AGMA) rating standard, ANSI/AGMA 2101-D04, “Fundamental Rating Factors and Calculation Methods for Involute Spur and Helical Gear Teeth” [1], uses load reversal and reliability factors in the calculation of the rated load capacity for gear teeth. This paper proposes a useful method to calculate the reliability factor instead of using […]

Optimizing Gear Macro and Microgeometry To Minimize Whine and Maximize Robustness for a Diesel Engine Application

A system approach is used to optimize the macro and micro design to minimize the transmission error while ensuring that robustness (bending, contact, scuffing, and micropitting) safety factors are not compromised.

The desire for engines that provide more torque and power is driving higher loads into the gear train. At the same time, expectations for noise, vibration, and harshness (NVH) require systems that are even more refined. The gear train design engineer has several factors available to consider; some are controllable, and others are not. Given: […]

Evolution of Heat Treating Furnaces for Gears

There have been 40 years of fascinating projects, unforgettable facilities, and forward-thinking people in the gear and heat treat industry.

It’s the mid ’70s, the phone rings, and I’m told that Ford wants to upgrade their heat treat equipment at the Rouge facility. Driving in, I am awed at the size and history of the complex. As I enter the heat treat department, I see the furnace operator about to seal and load a retort […]

Gear Corrosion in the Manufacturing Process

Corrosion in the gear manufacturing process is a significant issue that must be corrected to avoid premature failure.

No matter how well gears are designed and manufactured, gear corrosion can occur during the manufacturing process, which may, in turn, result in catastrophic failure. To further complicate matters, corrosion can easily go undetected during normal visual inspection especially in the difficult-to-observe areas. Corrosion can appear in different forms such as pitting, crevice, and intergranular […]

Achieving Gear Design Success

When evaluating a new or existing spur gear design, there are important areas that should be evaluated.

After a gear design is completed, enough of the gear, stress, and life data is established so that the gear set can be completely described and all of the relevant gear data specified in order to manufacture and rate the gears involved. From this gear data, the following items should be evaluated: Contact Ratio: This […]
