Cycloidal gear reducers are commonly used for speed reduction where machine needs high reducing ratio and/or high torque drive. In the past decades, a great amount of research has been focused on the design of cycloidal gear reducers and many patents were also invented. Nonetheless, not much research has addressed the topological structure of the cycloidal gear reducers. In the first part of this thesis, the topology of the cycloidal gear reducer is analyzed first. Then structural characteristics of such mechanisms are investigated and summarized. Subsequently, a methodology for synthesizing new cycloidal gear reducer is proposed and new mechanisms are enumerated. In the second part of the thesis, the dynamic analysis of the reducer is conducted via Newton’s law and linear elasticity. Finally, the efficiency of reducer is studied when taking the inertia effect into account. The result shows that the cycloidal gear reducer is able to remain high torque when the mechanical energy varies.

At present, the common manufacturing method of cycloidal gears seen on the market is grinding after hobbing. The extrusion processing of cycloidal gears is a new research field. Although the manufacturing time is relatively short, it also has the disadvantage of difficult to control the size and accuracy, which has caused many troubles to the actual production. To solve the problem of the precision of extruded products, many people will use analysis software to simulate and analyze the situation of products after processing, and then amend it to reduce waste generation. But after simulation, the output drawings of the products show irregular triangular mesh, which makes the surveyors not know how to start. At present, there is no complete measurement method for this aspect. So this paper proposes DEFORM 3D triangular mesh tooth profile error evaluation and compensation to improve this situation. This paper first established several mathematical models, the cycloid gear and do the physical move, modification way equation is expressed. Then, with the help of these mathematical models, this paper will explain in detail how to use DEFORM 3D triangular mesh to evaluate and compensate tooth profile errors after extruding gear samples with simulated Workpiece, extract data points on a single cross-section from the samples and calculate their errors with theoretical values, so as to benefit further. The compensation of the left and right tooth surfaces of the lower die is calculated by the sensitivity matrix, and then the compensation correction is carried out subsequently. After that, a new cold extrusion simulation analysis process was established, especially the improved design of the lower and middle die of the extrusion die was more suitable for actual production and manufacturing. To verify the feasibility of the gear measurement and compensation method proposed in this paper, the details of the process setting and the experimental results will also be fully introduced in this paper.

The cycloidal gear is widely used in many industrial application for speed and torque transmission purposes because the advantages of high efficiency, large ratios, compact design, long and reliable working life. A fine design about the geometry of the output shaft will decrease the stress concentration on the gear disc when transferring power. In this study, a computer program is developed for calculating the profile data of the cycloidal gear and export to Pro/E software to create a 3D cycloid mechanism module for dynamic analysis. The dynamic models considering friction, gear clearance and time-varying stiffness were established. The ANSYS/LS-DYNA is utilized to analyze the dynamic responses of gear transmission, surface contact stresses, root bending stresses, and contact stress of the output shaft of a cycloidal mechanism. The stiffness and elastic deformation of gear teeth are calculated by using the finite element method with actual geometry and positions of the gears. The modified suggestion of the geometry of the output shaft will be carry out by the results of dynamic simulation.

The process of the cycloidal gear movement is driven by point contact, Therefore, if the tooth shape is poorly designed, the tooth surface of the cycloidal gear will be uneven during operation. The tooth surface wear is different and the transmission accuracy and service life are reduced. In order to make the tooth surface force close to uniform size. In this paper, the tooth surface is evenly stressed, Minimum tooth surface stress and Minimum tooth surface maximum stress wave front difference is the target. Use optimization analysis to achieve the above conditions and find the best parameter values from the process of optimization analysis. The main factors controlling the tooth profile of the cycloidal gear are two parameters of equidistant shape modification and distance modification. Write a toothed program by programming the software to control the two factors of equidistant shaping and shifting, Calculate the cycloidal gear parameters, To facilitate the shaping of the tooth profile, Optimized experimental planning with Design-Expert optimized software, Tooth shape control according to the equidistant shape modification and the distance correction parameter value obtained in the plan, And calculate the tooth shape and import it into the 3D software to build the three-dimensional model of the tooth profile and the three-dimensional model of the components of the planet carrier, the pin wheel and the eccentric shaft, And organize them. To simulate the position of the RV reducer, The constructed 3D assembly model is then imported into the HyperMesh preprocessor for finite element model partitioning, material property setting, coordinate system setting, initial condition setting, contact mode setting, constraint condition setting and output condition setting. Finally, the finite element analysis software LS-Dyna is used to calculate the tooth surface force. A total of 4 sets of experiments verifying the CAE analysis model were performed with subsequent tooth profile comparison with an accuracy of 97.8%. Finally, the optimized tooth profile has a maximum stress of 193.064 MPa at a distance of -0.005 mm and an equidistant 0.0047 mm. The tooth profile is used to regulate the maximum tooth stress of the Nabtesco RV-27C tooth profile to 188.09MPa. The accuracy between the two is 97.4%.

Cycloidal reducers have been applied for the transmission mechanism in precision machine for a long time. Recently, the development of cycloid gear reducers has been focused on the high torque density design. In light of this trend, it is necessary to understand and explore the gear reducer in the force/torque aspect. This thesis first reviewed the methods of force analysis for cycloid gear reducers. Then, a method based upon the superposition method is proposed for the analysis of the contact force between cycloid lobe and pin. The results are compared with the results of FEM analysis as well as traditional force analysis method. This paper also presents the detail simulation process using the FEM software. The process shows that convergent results can be achieved by using the parameters selected in the thesis.

In this study, the mathematical models cycloidal gears are derived based on the theorem of gearing firstly. Then, the meshing model of cycloidal gear pair is set up and tooth contact analysis (TCA) is adopted to investigate the transmission errors with different design parameters and assembly conditions. Furthermore, the general-purpose FEA software, ABAQUS, was applied to evaluate the formation of bearing contacts and stress distribution on the tooth surfaces according to different design parameters. Results in this study not only verify the contact nature of cycloidal gear pairs, but also provide the bases for upcoming research on cycloidal gear pairs such as curvature analysis and sliding ratios.

As factory production gradually evolves toward automation, robotic arm replacement is the current trend. Because the mechanical arm joint output is large, it is necessary to use a small volume and high-speed ratio precision reducer to increase the torque. Therefore, cycloidal gears with high gear ratio, small size, lightweight and low noise are often used in robot arms. The purpose of this paper is to develop the accuracy evaluation method of cycloidal gear and propose a mathematical model for accuracy evaluation. Firstly, the 2D point data of the tooth profile are imported, and all the measurement points are center-corrected by the conjugate gradient method, advance and retreat method and the golden section method in the one-dimensional search method. After that, using the B-spline curve fitting method to fit the measurement points, to ensure the fitting curve, the fitting error will be further calculated. After confirming the condition of the fitting error, the pitch radius is used to find the pitch points of the left and right tooth. The content of the evaluation of cycloidal gear in this paper is mainly divided into two parts. The first part is the evaluation of pitch error. The pitch error of the cycloidal gear can be evaluated using the found pitch points and the calculations defined by DIN. There are three calculation items for the pitch error evaluation according to DIN 3960[19], including single pitch error, accumulated pitch error, and run out. After calculating these pitch errors, the database can be further used to make a database using the evaluation level compiled by DIN3962 [20], and the database can be used to judge the accuracy level of the pitch errors. The second part is the calculation of the tooth profile and tooth thickness error. Before calculating the tooth shape error, the theoretical tooth profile and the pitch point of the fitting tooth profile must be coincident, and then the error of the fitting point and the corresponding theoretical point are calculated. The tooth thickness is subtracted from the fitted profile and theoretical one. Using the established method to evaluate the accuracy of commercially available products can be used as a basis for determining the manufacturing tolerance of cycloidal gears.

Cycloid reducer have many uses in industry, and is compact structure and with high efficiency speed reducer. Until now, for the study of cycloid reducer is to research its unique tooth profile. The formation of tooth profile have several ways, but for how to design a different gear ratio is not systematic design approach on cycloid reducer. This paper is proposed design method for different gear ratio of speed reducer and hope the backlash well minimum when speed reducer is rotation without interfering. For how to make the backlash to reduce method is adjusting the main parameters affecting the gear backlash to observe its changes, the most important that influence cycloid reducer have four factors. First, the arc radius of the ring gear, second, the distance from arc center of the ring gear to center of the ring gear, third, the arc radius of the cycloid gear, fourth, the distance form smaller arc center of the cycloid speed to center of the cycloid gear. By adjusting the size of the four factors to find the design parameters and make the backlash well minimum when speed reducer is rotation, and applied in gear ratio of 1:3, 1:5, 1:10, 1:15 speed reducer. Finally, using computer to design the CAD model and dynamic simulation software to simulate the movement of the situation, verify the accuracy of the size design.
