Kinematic Efficiency of Non-Circular Geared Transmissions

Journal of Mechanical Design, 1981
Infinitely-variable transmissions of high efficiency can be made using non-circular gears combined in function generators. The efficiency of a function generator depends on the gear parameters, the ratio of the differential, and the direction of power flow.

Application of Non-Circular Planetary Gear Mechanism in the Gear Pump

Advanced Materials Research, 2012
Gear pump is the most commonly used hydraulic component in hydraulic drive system.Volumetric efficiency of the traditional gear pump is low, big flow ripple causes large pressure fluctuations, makes pipes and valves vibration, noisy. The imbalance pressure on gear pump’s gears, shafts and bearings and the large radial load limits its pressure increased.

Synthesis and evaluation of non-circular gear that realizes optimal gear ratio for jumping robot

2013 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2013
For the effective use of motor power, an appropriate gear ratio has to be selected according to the robot task and motion. Because a jumping robot, in particular, requires both high torque and high velocity properties through the motion, a varying gear ratio is necessary. Moreover, it has to be optimally designed and realized.

KINEMATICS OF ROTATION OF NON-CIRCULAR GEAR WHEELS

REPAIR RECONDITIONING MODERNIZATION
The study of the kinematics of gears with non-circular gear wheels, including the analytical construction of centroids, the determination of gear ratios and the analysis of the movement of the driven link has been carried out. It is shown how the shape of the centroid affects the dynamics of rotation and can be adapted to specified cycles.
