FEATURES

Felsomat

As an innovative leader in production technology, Felsomat provides highly efficient and flexible systems for the transmission and engine manufacturing industries.

Based in Koenigsbach Stein, Germany, Felsomat GmbH was founded in 1981 by Helmut F. Jaeger — initially manufacturing small pick-and-place devices and simple automations systems. In 1990, Felsomat became a trendsetter in the machine tool industry with its introduction of the FZ 250 compact cell. This automation system revolutionized the way in which small gears […]

Pitch Factor Analysis for Symmetric and Asymmetric Tooth Gears

Pitch factor analysis is an analytical tool that can be used for comparison of different gear geometry solutions by exploring the characteristics of involute gear mesh parameters that define gear drive performance.

In comparison with traditional gear design based on pre-selected, typically standard generating rack parameters and its addendum modification also known as the X-shift, the alternative Direct Gear Design® method [1, 2] provides certain advantages for custom high-performance gear drives that include increased load capacity, efficiency, and lifetime and reduced size, weight, noise, vibrations, and cost.

Accelerated Testing and Temperature Calculation of Plastic Gears

Comparing different material combinations and testing conditions, results are presented from an accelerated testing procedure for polymer gears to provide a more accurate calculation of gear temperatures.

Plastic gears have been in use since the 1950s, and their popularity has increased significantly in the last few years. The mass production of plastic gears using injection moulding and newly developed plastic materials have additionally increased the application of plastic gears in automotive and medical areas. The primary advantages of plastic gears are low […]

Application of Advanced Mesh Analysis To Eliminate Pinion Failures

A case study demonstrates the benefits of advanced mesh analysis, including design and application of optimized microgeometry through precision tooth form grinding. Recommendations can be applied at the design phase to optimize gearing performance or, reactively, to identify root cause of failures.

Through a case study involving pinion failures on plastic extruder drives, this paper covers failure analysis, gear rating review, application of advanced mesh analysis to define component deflections causing loaded mesh misalignment, and reduced tooth contact/high stress concentration resulting in tooth macropitting. The paper demonstrates the capability and benefits of advanced mesh analysis, including design […]

Thermochemical Surface Technologies Applicable to Gears

Comparing wear resistance of nitrided and carburized cases formed on the same steel can help designers choose which method to use.

Hardening of the gear surfaces has a profound effect on their performance. Reduction in friction, enhancing rolling contact fatigue resistance, and other tribological properties of the surface can be utilized by application of various surface techniques available to the manufacturing industry. For surfaces hardened by a diffusion process, what really matters is the depth of […]

Comparing Surface Roughness Parameters

Measurements such as Ra, Rz, and Rsk may not effectively evaluate isotropically superfinished surfaces.

Effective gear design must account for a range of potential failure modes. As discussed in previous Materials Matter columns, gear failure modes can be fatigue-based and progressive (such as micropitting) or sudden (such as scuffing). Surface roughness is an important design factor in predicting and avoiding gear failure. Therefore, accurate classification of surface roughness is […]

Requirements for Gear Design

The following steps help ensure a successful gearbox is designed and specified, and all of the customer’s desired attributes and design inputs are met.

A gearbox design program includes technical and non-technical requirements, including legal and regulatory as well as commercial considerations. The process starts with a description and full understanding of the type of gear or gearbox required and the nature of the application: what type of machine will it be used in, where and how will it […]

Trend Talks: Virtual Reality

It’s no holodeck, but virtual reality in heavy industry is becoming a reality.

Science fiction has done a lot to inspire and influence aspects of everyday life. Engineers and industrialists look to what fiction writers have thought up out of thin air and have tried to make them reality. Lasers, smartphones, GPS tracking, and more got their start in the pages of sci-fi novels and movie scripts. Industry […]
