A method to calculate pitch cones for hypoid gears using macrogeometry parameters—similar to non-offset bevel gears—while accounting for the added complexity of hypoid offset, tooling, and cutting technology is explored in this paper.
This study explores the failure mode morphology of FZG-A test gears. It aims to examine the orphologies of scuffing, scoring, scratches, and polishing using high-magnification light optical microscopy (LOM) and scanning electron microscopy (SEM) images.

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 paper will review the development process, current research status, characteristics, functions, and measurement methods of TE. It will analyze the difficulties and core issues existing in the basic theory of TE, clarify the limitations and deficiencies of TE, and explore ways to overcome the shortcomings of TE.

Due to near-net shape production, additive-manufactured (AM) gears have a high potential to decrease costs and increase resource efficiency. The decreasing product life cycles as well as the increasing individualization of components demand high flexibility in manufacturing processes
When grinding steel parts, the surface of the part can "burn" if too much heat is applied in a short time. Grinding burn refers to all those structural changes in edge zones of steel parts that are caused by grinding processes in steels due to the thermal energy introduced. Grinding burn can mainly occur in the form of tempering zones or new hardening zones.
For precision measuring, skilled machinists, toolmakers, and inspectors must have accurate tools and gages, produced from quality materials, carefully manufactured, and rigidly inspected, to ensure lasting dependability. Gages have evolved throughout the years beginning with mechanical, then electronic models, and now convenient wireless electronic versions have come on the scene. Each type has an important place in today’s quality control and inspection processes.
