CAD-based simulation of the hobbing process for the manufacturing of spur and helical gears
Targeting an accurate and realistic simulation of the gear hobbing process, we present an effective and factual approximation based on three-dimensional computer-aided design. Hobbing kinematics is directly applied in one gear gap. Each generating position formulates a spatial surface path which bounds its penetrating volume into the workpiece. The three-dimensional surface paths generated from...
متن کاملCooling and Lubrication of High-speed Helical Gears
Centrifugal compressor and turbine manufacturers are building machines that operate at increasingly higher speeds to reduce the size and cost of their equipment. Helical gears are commonly used to step down the speed of these machines to match nominal motor and generator speeds. The demand for higher compressor and turbine speeds has resulted in an increase in the maximum pitch line velocities ...
متن کاملHelical Quantum Edge Gears in 2D Topological Insulators.
We show that two-terminal transport can measure the Luttinger liquid (LL) parameter K, in helical LLs at the edges of two-dimensional topological insulators (TIs) with Rashba spin-orbit coupling. We consider a Coulomb drag geometry with two coplanar TIs and short-ranged spin-flip interedge scattering. Current injected into one edge loop induces circulation in the second, which floats without le...
متن کاملPackaging double-helical DNA into viral capsids.
DNA packaging in bacteriophage P4 has been examined using a molecular mechanics model with a reduced representation containing one pseudoatom per turn of the double helix. The model is a discretized version of an elastic continuum model. The DNA is inserted piecewise into the model capsid, with the structure being reoptimized after each piece is inserted. Various optimization protocols were inv...
متن کاملThe left-handed double helical nucleic acids.
The conversion of right-handed dsDNA and dsRNA to the left-handed Z-conformation involves a reorganization of the nucleotides relative to each other. This conversion can be facilitated by the tight binding of a Z-conformation-specific protein domain from the editing enzyme dsRNA adenosine deaminase. This may influence the modification of both pre-mRNAs as well as some replicating RNA viruses.
