Computational Design and Optimization of Non‐Circular Gears [PDF]
AbstractWe study a general form of gears known as non‐circular gears that can transfer periodic motion with variable speed through their irregular shapes and eccentric rotation centers. To design functional non‐circular gears is nontrivial, since the gear pair must have compatible shape to keep in contact during motion, so the driver gear can push the ...

Gear shape optimization for non-circular gearing
Abstract The quality of gearings is largely decided by their geometric design. If the geometric design is incorrect, the reliability of the transmission will not be ensured even by the use of the highest quality materials. Conversely, sometimes excellent geometric gear design can save expensive material costs.

Technological Aspects in Manufacturing of Non-Circular Gears [PDF]
The construction and manufacture of non-circular gears is one of the most difficult issues in machine technology. Due to the limited technological capabilities of traditional machines and tools, past manufacturing methods were unable to calculate the assumed shape of the tooth line and its profile.

Teeth deformation of non-circular gears
In practice, gear units whose transmission number is not constant during one revolution are used. Such gears include the proposed elliptical transmission. Its application can be (missing a word?) and the automotive industry. The gears set consists of a pair of identical elliptical gears.

Application of acoustic emission to seeded gear fault detection [PDF]
Acoustic emission (AE) is gaining ground as a non-destructive technique for health diagnosis on rotating machinery. There are vast opportunities for development of the AE technique on various forms of rotating machinery, including gearboxes.

Designing of non-circular gears
In this paper, the authors present methods for designing of non-circular gears, including internal and external gears with spur or helical teeth. Technology related issues that determine tooth profile calculation algorithm are described. The results presented in this paper can become groundwork for further investigations of other particular properties ...

Intermittent gear rattle due to interactions between forcing and manufacturing errors [PDF]
The interaction between eccentricity and an external forcing fluctuation in gear rattle response is investigated experimentally. The experimental rig consists of a 1:1 ratio steel spur gear pair, the input gear being controlled in displacement and the ...

DEVICE FOR MACHINING NON-CIRCULAR GEARS
If at first the non-circular wheels were treated as a hobby subject, their use now becomes ever larger. They are used in robotics, replacing cam mechanisms and lever mechanisms in the textile and agricultural industries. The paper presents a device used for the processing of non-circular gears, a device made according to my own design.
