Cylindrical gears have a wide range of applications in the manufacturing industry because of their advantages. And it is of great significance to study the design techniques and optimization methods of cylindrical gears. In this paper, parametric primary design of single-stage helical gear drive is discussed. And parametric design of the cylindrical gear is carried out by using optimized design...

In this paper we present a new method for analyzing and developing the hypoid gears in order to improve their constructive and technological particularities.. The first part describes the methodologies for optimization the backlash. Then, the variation of the normal vectors and curvature is analyzed in the neighbourhood of the contact point. In the final part is presented a method for modelling...

The subject of this paper is the synthesis of spatial cycloidal gears, based on Disteli’s work, which was published at the turn of the 20th century. In particular, the properties of the Plücker conoid or the cylindroid for the relative motion between a pair of skew gears are analyzed in order to extend Camus’ Theorem from the planar and spherical cases to the spatial case with the aim of synthe...

Ordinarily, gears and belt drives are used for uniform transmission of rotations between parallel axes. Here we focus on the nonuniform case, i.e., with non-constant transmission ratio. We treat the geometry of tooth profiles and pulleys and their algorithmic computation. Concerning gears, we recall a method due to S. Finsterwalder. Concerning belt drives, we study their relation to tooth profi...

Gear plunge shaving is one of the most efficient ways to finish gears. It has been a challenge for a long time to design and manufacture a plunge shaving cutter to induce gear tooth modification. This paper proposes a method for designing plunge shaving cutters to manufacture gears with modifications analytically. By integrating B-spline interpolation, differential geometry, and design optimiza...

Somer M. Nacy, Member, IAENG, Mohammad Q. Abdullah, and Mohammed N.Mohammed Abstract The Wildhaber-Novikov gear is one of the circular arc gears, which has the large contact area between the convex and concave profiled mating teeth. In (June 28, 1999), a new geometry of W-N gear with parabolic profile in normal section has been developed. This paper studies the generation of rack-cutters for p...

Diagnostics of faults in gears requires development of reliable condition indicators. A large number of condition indicators, which are based on statistical moments of the synchronous average and its derivatives (difference and residual signals) were previously suggested. This study evaluates the efficiency of different gear condition indicators that are based on statistical moments and compare...

This paper presents design and torque analysis in various types of magnetic gear with different magnetic materials and air gap. This type of gear offer both high speed and high torque required for drive applications. In the proposed gear analysis the low speed side is connected to prime mover and high speed side is connected to load, suitable for wind power, automobile applications and group dr...

The ability to manufacture and manipulate components at the micro-scale is critical to the development of micro systems. This paper presents the technique to manipulate micro/nano parts at the micro/nano-scale using an integrated Focused Ion Beam (FIB) system composed of scanning electron microscope, micro manipulator and gas injection system. Currently the smallest gears manufactured with trad...
