Impact of Surface Condition and Lubricant on Effective Gear Tooth Friction Coefficient

An experimental study, with variables including superfinishing, coated gear teeth, and two different lubricants, evaluates the effective coefficient of friction in a gear mesh, resulting in a parameter that could be utilized in estimating frictional losses in a gearbox.

The impact of gear tooth surface roughness and advanced coatings on frictional losses in a gear mesh is of significant interest to the transmission community, as these losses reduce the efficiency of the drive system. Maximizing efficiency to save fuel has long been an objective in vehicle industries. In recent years, the power generation sector […]

The Internet of Gears: New Perspectives Through CMS

This approach from Renk AG allows manufacturers to form a network with their products, allowing operators and gear designers an accessible set of data and providing advantages to not only the end user but also to all involved in the purchase, design, commissioning, application, and maintenance.

During the past decades, the capacity of production machinery increased continuously in nearly all industries. A doubling of the capacity in a time span of 20 years is a coarse but helpful point to fathom. With machinery becoming more powerful, investments per unit increased significantly. Thus, in order to expedite the return on investment, machinery […]

Worm Screw High-Speed Manufacturing

A comparison of standard worm hobbing to the worm screw power skiving (WSPS) process is discussed, including cutting speeds, axis rotational speeds, machine kinematics, and machine configuration. A calculation example for small-pitch worm screws shows that a manufacturing cycle time can be reduced with the WSPS process.

This paper shows how to produce worm screws when your actual gear hobbing machine configuration has the hob axis perpendicular to the workpiece axis with a swiveling of ±30 degrees for the hob head to produce helical gears. As known, from the perpendicular axis of the workpiece, the helix angle of a worm screw is […]

Common Gear Failures

A systemic failure analysis aids in identifying the root problem of a gear failure, and once identified, there are ways to avoid the most common culprits.

The strength, toughness, and cost effectiveness of steel make it the most widely used material in gear-making [4]. Different steel compositions offer an array of hardness and hardenability depending on the carbon and alloy contents of the steel type. Heat-treat response and surface treatment alter the microstructure and influence the wear and fatigue properties of […]

Non-Design Engineering Considerations

Design engineers should contemplate non-design engineering considerations while designing a gearbox or any other component.

The function of design interacts with non-design engineering considerations and functions of a product. Four key elements include: design for manufacturing, design for assembly, design for inspection, and design for quality, also known as quality by design. Design for Manufacturing In the design process, every component manufactured must have the manufacturing processes considered. Can the […]

Surface Engineering of Steels

Surface engineering draws upon chemistry, material science, metallurgy, tribology, and biology to enhance surface properties for improving parts.

The ASM Handbook [1] defines surface engineering as: “treatment of the surface and near-surface regions of a material to allow the surface to perform functions that are distinct from those functions demanded from the bulk of material.” The surface properties can be enhanced or changed to improve lubricity for forming, surface hardness for wear resistance, […]
