Unloaded transmission error and instantaneous gear ratio for non-circular gears with misalignments
Mechanism and Machine Theory, 2022Unloaded transmission error (UTE) determination is well established for gears with uniform motion. This established methodology is modified and applied to the case of non-circular gears. Reciprocity between two screws is introduced as part of this modification. One screw is a wrench defined by the tooth contact force and the other screw is a twist that

Prevention of resonance oscillations in gear mechanisms using non-circular gears
Mechanism and Machine Theory, 2017One of the main disadvantages of gear mechanisms is the occurrence of noise and vibrations. This study investigated the applicability of non-circular gears for preventing resonance oscillations in ...

Modeling and Dynamics Analysis of Non-Circular Gears
Proceedings of the 2020 2nd International Conference on Big Data and Artificial Intelligence, 2020Compared with circular gear, the tooth shape, pitch diameter, tooth profile equation and meshing characteristics of non-circular gear are constantly changing. Variable transmission ratio can be achieved. According to the characteristics of the non-circular gear, the pitch curve was designed and the non-circular gear was modeled by Pro/E.

Efficiency of Non-Circular Spur Gears
Transactions of the Canadian Society for Mechanical Engineering, 1983Continuously variable mechanical transmissions employing non-circular spur gears are presently being developed. Such devices are expected to be as efficient in terms of friction losses as common standard automobile transmissions. Tests were carried out using a specially designed power-circulating gear test apparatus to compare meshing losses for non ...

Synthesis of the Pitch Surfaces of Non-Circular Skew-Gears
Volume 2: 34th Annual Mechanisms and Robotics Conference, Parts A and B, 2010The subject of this paper is the synthesis of the pitch surfaces of non-circular skew gears, intended to generate any motion program with a periodically varying transmission ratio. This is done by extending an existing algorithm, which was formulated through the application of dual algebra and the Principle of Transference.

Prediction of the Efficiency of Non-Circular Spur Gears
Transactions of the Canadian Society for Mechanical Engineering, 1984This paper reports predictions and test results which indicate the average loss rate per revolution for non-circular gears can be considered essentially the same as those for circular gears given similar specifications and operating conditions. There is, however, a significant variation in loss rate with respect to non-circular gear angular position.
