Hobbing the Bevel Non-Involute Pinion of Helical-Bevel Gear оf Internal Meshing

Bulletin of Kalashnikov ISTU, 2017
Рассматривается передача с конической шестерней и цилиндрическим колесом внутреннего зацепления, которое изготовляется зубодолблением по обычной технологии. При формировании рабочих профилей зубьев шестерни цилиндроконической передачи внутреннего зацепления возникает технологическая проблема получения рабочего профиля зубьев.

Design of Gearings from Involute-Bevel Gears

Vestnik IzhGTU imeni M.T. Kalashnikova
The article presents formulas for determining the dimensions of involute-bevel gears and the gearings composed of them. It examines the most general cases of gearings formation, consisting of two involute-bevel gears with crossing axes (hyperboloid gearings), with intersecting axes (bevel gearings), and with parallel axes (cylindrical gearings ...

Wavelet application research on tooth surface of spherical involute spiral bevel gear [PDF]

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2018
In order to improve the machining accuracy of spiral bevel gears, a scheme based on the cubic B-spline wavelet was proposed. Based on the principle of spherical involute formation, a program was made in MATLAB to obtain the coordinate data of discrete points of the tooth surface.

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]

, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Evaluation of Contact Stress and Fatigue Life for Roller Crowning Profiles in Triple Roller Pitch Bearings

Wind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT This study investigates the contact stress and rating life of a three‐row pitch bearing for wind turbines, considering the effects of roller crowning. All crowning profiles were logarithmic, and a total of six profiles were examined based on the Romax, ISO 16281, and Fujiwara equations.

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, Volume 22, Issue 39, 13 July 2026.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Formation of Tooth Profiles of Non-Involute Bevel Gears at CNC Machines

Intellekt. Sist. Proizv., 2018
В работе рассмотрена цилиндроконическая передача внутреннего зацепления, состоящая из эвольвентного цилиндрического колеса с внутренними зубьями и конической (по форме заготовки) неэвольвентной шестерни, ось которой наклонена к оси колеса. С использованием этих зацеплений могут быть созданы эксцентриковые планетарные передачи с двумя наклонными ...

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change

European Policy Analysis, Volume 12, Issue 2, Spring 2026.
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled
