Reducing Tool Wear in Spiral Bevel Gear Machining with the Finite Element Method

This virtual design approach uses real-world cutting tool geometry, automatically generated gear blanks, and known process kinematics to simulate the cutting process.

Due to the complexity of spiral bevel gear machining, the cutting tools can be a significant cost of gear manufacturing. Unlike the price of the material, which is fixed by the market, the cost of tooling and subsequent re-grinding can be lowered through reducing tool wear and increasing tool life. Current methods for making these […]

Experimental tests to predict plastic gears’ lifetime

Experimental tensile fatigue data can be used to predict plastic gear life and the polyamide-based polymer loaded with glass fibers can be used for the metal replacement of gears used in applications with high power.

One of the major problems of plastic gears is the lack of data about their lifetime. Literature doesn’t contain numerous data on this subject. Even if it reported them, the number of tests, the variables involved, and the test methods are so varied that it would be difficult to compare them with those needed. This […]

Understanding the mounting distance: Intersected-axes gearing (bevel gearing)

To favorably configure bevel gears in intersected-axes gearing, the mounting distance must be one of the most important design parameters.

Mounting distance is one of the most critical design parameters in intersected-axes gearing (in straight bevel gearing, spiral bevel gearing, and so forth). In this article, the mounting distance is discussed with focus on “geometrically-accurate gearing” (that is, with focus on “perfect” gearing). The term “geometrically-accurate gearing” means gearing with zero deviations of the actual […]

Roughness measurement tips: 2- vs. 5-micron

Depending on operating conditions and the flank surface being measured, there are times a 2-micron tip can measure a significant difference compared to a 5-micron radius tip.

I’ve written three articles on gear flank roughness measurement for this magazine (Materials Matter; January 2016 and February 2016, and an issue-focus article in January 2019). Those articles gave guidance on the setup and measurement of the roughness parameters (Ra, Rz, Rmr, etc.), the complete roughness diagram needed to specify roughness on a gear drawing […]

Cost, cleanliness, carbon footprint affect quenchant

Weighing the application of vegetable-based quenchants for heat-treating applications.

Vegetable oils are seeing increased interest as quenchants for steel because of low carbon footprint, a renewable resource, and the ability to reclaim/recycle into bio-fuels. There are many different types of vegetable oils, and considerable research has gone into the viability of these oils for applications in quenching [1] [2] [3]. Vegetable oils are extracted […]

Internal ring gears – design and considerations 

When using internal ring gears, you can develop a gear system with a high reduction ratio in a compact space — but there are considerations regarding the reduction ratio, interference possibilities, and design window dimensions. 

When one is under a great deal of stress, they have a choice to either internalize the stress or to express it. Some express it through exercise, some drown their sorrows at the neighborhood pub, and some choose to berate others. In gearing, there are situations when internalizing the gear mesh is desirable. For these […]
