Investigations on the Efficiency of Worm Gear Drives

Experimental investigations on different worm gears were conducted on several test rigs, taking into consideration the influence of different gear ratios, worm wheel materials, lubricants, and contact pattern on efficiency and load-carrying capacity. Recommendations for an increase in overall worm gearbox efficiencies are presented.

Due to a wide range of properties, worm gears are an indispensable element on the current transmission market. Next to a huge gear ratio field in one gear stage of i = 5 to i = 80, operation with low noise and vibration is realizable. Furthermore, worm gears provide the opportunity of self-locking, respectively self-braking. […]

Shear Stability Is Key to Proper EAL Gear Oil Selection

To prevent failures of bearings and gears, careful selection of EALs for use in marine components, combined with a good oil sampling program, are necessary.

Selecting a gear oil for use in marine thrusters or a stern tube lubricant for use with propeller shaft bearings is typically based on analyzing price and performance characteristics of the lubricant and its availability. Now, with the implementation of the 2013 Vessel General Permit, this analysis must be expanded to include environmentally acceptable lubricants […]

An Update on Broaching Technology

Advances in both broach tools and broach machines have progressed the state of the art in broaching.

The world of broaching has certainly changed since the 1850s when it emerged as a viable production metalworking process. Advancements have been made in machine technology, processes to increase performance, and specialty coatings to improve tool life. Broach Tool Advances Most manufacturers seek higher productivity and lower costs as ways to improve profitability. The cutting […]

Optimizing Performance with Surface Finish and Lubrication

Lubrication in mechanical power transfer systems can have superfluous or detrimental properties if not optimized relative to the surface finish of the components.

Materials and manufacturing processes have evolved to generate lighter, stronger, and more robust components to meet the demand for more efficient, highly loaded mechanical systems. The importance of the surface of these components relative to their operational performance was presented in the December 2015 Materials Matter column, “Gear Surfaces and Operational Performance.” Additionally, the lubrication […]

Variables for Quality Design: Application

A complete understanding of where the gearing will be used, the surrounding environment, and external influences is an essential starting point for achieving a quality design.

In the February Tooth Tips column, an overview was presented of the four major elements — application, specifications, design, and process — that dictate the ultimate accuracy of gearing and how well it satisfies the customer. Within this series, we take a closer look at each, starting with application. Application During the application phase, there […]

Trend Talks: Quality Control and Inspection

When it comes to manufacturing high-quality gears, quality control and inspection play crucial roles in meeting industry standards and a customer’s specific needs.

Gear quality control and inspection are important steps in the process of checking the overall quality of manufactured gears and parts. It also provides insight into the levels of efficiency and control as they pertain to the manufacturing process, ensuring that the parts are made to meet high-quality standards as well as the customer’s specific […]

Modern Nitriding Techniques for Gear Applications

Among thermochemical methods, the processes of plasma nitriding and gas nitriding have progressed in the industry to increase gear performance.

Improving surface properties of gears can be extremely beneficial since many failures start at the surface in the contact area between the teeth [1]. Rolling contact fatigue properties of the gear surface are improved when a hard diffusion layer — with the compressive residual stresses built into it by the thermochemical surface engineering methods — […]
