This study examines the implementation and experimental validation of state-of-the-art plastic worm gear design methods, focusing on the VDI 2736 guideline as the most comprehensive reference for load-carrying capacity calculations.
With government mandates to reduce greenhouse gas (GHG) emissions, decarbonizing the largest industrial emitters has become an essential research focus. The Environmental Protection Agency (EPA) reported that industrial point sources in the United States (U.S.) emitted 1.45 billion tons of carbon dioxide (CO2) in 2022, accounting for 23 percent of all domestic CO2 emissions for that year (Refs. 1,2). One of the largest contributors to industrial emissions is the iron and steel industry, which was responsible for 2.5 percent of total U.S. GHG emissions in 2023 (Ref. 3). Due to the large quantity of emissions available for capture from this industrial sector, iron/steel production facilities present an impactful opportunity for industrial decarbonization.

This paper is divided into two parts. The first part is a general digression on the pressure angle on cylindrical gears. The pressure angle is a variable that plays an important role in defining the geometry of gears and hobs, yet it is not widely discussed. This introduction serves as a prerequisite for the second part of the paper. The second part will show an application case of choosing the most suitable hob to cut a given gear. In this selection process, particular attention will be paid to the pressure angle of the hob for cutting with modified rolling, i.e., with a reduced pressure angle compared to that of the gear.

High-performance plastic gears are increasingly replacing metal gears in several applications due to the many advantages they exhibit. The main ones are lower weight, no need for lubrication, cheaper mass production, significantly better noise, vibration and harshness (NVH) behavior and chemical/corrosion resistance. Most plastic gears are produced by injection molding, which enables great design flexibility, e.g., joining several machine elements into one molded part, while gear geometry modifications like enlarged root rounding or altered profile shapes are also possible (Ref. 1).

This study aims to propose a robust reverse engineering methodology for straight bevel gears, especially for those found in inter-wheel differentials.

Different component characteristics in electric vehicles lead to higher noise and load requirements in the automotive industry. E-mobility—to a certain degree—is changing how gear analysis and inspection is carried out. Dissecting noise issues in gears and gearboxes requires an analytical approach like a detective. The problem could stem from the design itself, tolerancing or tip/root relief issues, tooth flank form deviations like waviness or perhaps crowning issues that directly impact noise. Every aspect of gear production needs to be examined to provide the most accurate results.
Furnaces North America 2022 (FNA 2022), presented by the Metal Treating Institute (MTI), in partnership with its media partner, Heat Treat Today, is the heat-treating industry’s go-to event every other year.
