Force Simulation of Cycloid Gear of Horizontal Three-Gear Cycloid Reducer
Applied Mechanics and Materials, 2011Co-Authors: Tian Min Guan, Shu Lian ZhangAbstract:The speed reducer with three Cycloid gears, namely FA high-precision drive speed reducer, is the most advanced drive device all over the world. The speed reducer has the advantages of small size, little weight, large drive range, long service life, good rigidity, good stability and precision, high efficiency and stable drive. Compared with wave drive by robots, the speed reducer has better fatigue resistance, bigger rigidity, longer service life and higher return difference precision; the FA speed reducer is used more and more frequently in becomes the weakest part of the whole structure. The paper mainly focuses on the study of this structure. When Cycloid drive adopts a large drive ratio, in order to avoid the interference of Cycloid gears, the size of gears is very small so that the strength of gears is reduced, which becomes the weakness for drive. Therefore, the paper adopts the new structure of horizontal gears. The paper analyzes the force upon Cycloid gears of this structure mainly by analysis, the sketch of this new structure of horizontal gears for three-gear Cycloid gear.

Journal of Advanced Mechanical Design Systems and Manufacturing, 2020Co-Authors: Bingkui Chen, Shigeki Matsumura, Chaoyang Li, Haruo HoujohAbstract:Cycloid drive is used widely in many industrial areas for both power transmission and precision transmission. In this paper a novel Cycloid drive is proposed and its meshing characteristics are analyzed. The conjugated gear pair of this novel Cycloid drive is composed by an external Cycloid-arc gear and an internal ring gear.

Secondly, based on coordinate transformation and gear geometry theory, the meshing equation for this novel Cycloid drive is established, the equation of the conjugated tooth profile and the formula of induced normal curvature are also derived. Thirdly, the meshing characteristics are analyzed based on a numerical example: the drawing of the conjugated tooth pair is presented and compared with the conventional Cycloid drive and the double-enveloping Cycloid drive; the contact lines between one tooth pair at different meshing positions are illustrated. Finally, the induced normal curvature is calculated and compared with that of the conventional Cycloid drive and the double-enveloping Cycloid drive, which shows good characteristic of this novel Cycloid drive.

Journal of Advanced Mechanical Design Systems and Manufacturing, 2020Co-Authors: Shigeki Matsumura, Bingkui Chen, Haruo HoujohAbstract:On a gear tooth surface, there may be some certain points which contact twice with its mating gear tooth surface. This phenomenon is called secondary action. In this paper, applying this phenomenon in Cycloid drive, a new type of double-enveloping Cycloid drive is generated based on gear geometry theory, and the torsional stiffness is calculated. The new conjugated tooth profile is composed by an external Cycloid tooth profile and a new generated internal ring gear tooth profile. The main characteristic of the new tooth profile is that there are double contact lines simultaneously between on tooth pair in a certain meshing area. In this paper, firstly the generation method of the new conjugated tooth profile is present, and the meshing characteristics are investigated. Secondly, the torsional stiffness calculation model for double-enveloping Cycloid drive is established. The normal stiffness, the arm length of the meshing force and the torsional stiffness are calculated. Finally, based on a numerical example, the calculation results are present, and the torsional stiffness of double-enveloping Cycloid drive is compared with that of the conventional Cycloid drive both on single tooth pair and whole gear mesh.

generation and investigation of a new Cycloid drive with double contact
Mechanism and Machine Theory, 2012Co-Authors: Bingkui Chen, Chaoyang Li, Hui Zhong, Tingting FangAbstract:Abstract A new Cycloid drive with double contact lines between one tooth pair is presented in this paper. The new conjugated tooth profile is generated by applying double-enveloping gear theory in Cycloid drives. Based on coordinate transformation and gear geometry theory, the meshing equation for this new Cycloid drive is established at first, then the equation of tooth profile and meshing line and the formula of induced normal curvature are also derived. The meshing characteristics are investigated by theoretical analysis and numerical examples: the double contact characteristic is revealed by that the meshing function can be resolved into two independent factors; the contact lines at different instant and meshing line are illustrated based on a numerical example; the superior characteristics of the new conjugated tooth profile is represented by comparison of induced normal curvature with conventional Cycloid drives. The physical prototype is trial-produced and the transmission error of the prototype is also tested, which shows that double-enveloping theory can be applied for Cycloid drives.

Reliability analysis on Cycloid double enveloping meshing pair
2012 IEEE International Conference on Mechatronics and Automation, 2012Co-Authors: Chaoyang Li, Jing Zhang, Bingkui ChenAbstract:Cycloid double enveloping meshing pair is widely used in many industry areas, such as Cycloid pin-wheel transmission, RV transmission and Cycloid rotor pump etc. It is comprised by the Cycloid gear and the envelop internal gear. The tooth profile of the Cycloid gear is the equidistant curve of the Cycloid, and that of the envelop internal gear is conjugated curve which takes the tooth profile of the Cycloid gear as the generating curve. Therefore, the Cycloid gear and the internal gear always mesh each other, without meshing boundary points. The reliability model of the Cycloid double enveloping meshing pair based on the first contact line is established after the comparison of the composite curvature radius at the two types contact lines. The tooth profile's contact stress for the meshing pair at the first type contacting point is calculated by Hertz contact method and FEA (Finite Element Analysis). Under the assumption that contact strength and the contact stress satisfy with normal distribution, the reliability design model of the Cycloid double enveloping meshing pair is analyzed. The results show that the reliability of the Cycloid double enveloping meshing is quite high.
