  • Computational approach to design face-milled Spiral Bevel Gear drives with favorable conditions of meshing and contact
    Meccanica, 2018
    Co-Authors: Alfonso Fuentes-aznar, Ramon Ruiz-orzaez, Ignacio Gonzalez-perez
    Abstract:

    The micro-geometry of the tooth surfaces of Spiral Bevel and hypoid pinions has to be fine-adjusted to obtain enhanced meshing and contact characteristics during the meshing process with their corresponding mating Gears. In this paper, a new methodology is proposed to design face-milled Spiral Bevel Gear drives to, firstly, derive favorable orientation and dimensions of the contact pattern between the mating surfaces of the Gears and, secondly, obtain a predesigned parabolic function of negative transmission errors with limited magnitude of maximum transmission errors. The proposed approach is based on the definition of the desired topography for the active surfaces of the pinion followed by a numerical derivation of their finishing machine-tool settings through a bound-constrained optimization algorithm. Increasing mechanical strength and reducing the levels of noise and vibration of face-milled Spiral Bevel Gear drives constitute the main objectives of the proposed design process. A numerical example is provided to illustrate the applicability of the developed theory .

  • Compensation of Errors of Alignment Caused by Shaft Deflections in Spiral Bevel Gear Drives
    Theory and Practice of Gearing and Transmissions, 2015
    Co-Authors: Alfonso Fuentes, Ramon Ruiz-orzaez, Ignacio Gonzalez-perez
    Abstract:

    The effect of errors of alignment on the bearing contact of Spiral Bevel Gear drives has been the subject of research for many years. Generally speaking, Gear misalignment causes transmission errors and edge contacts, leading to incremental levels of noise and vibration, and a reduction of the Gear drive service life. Apart from assembly and/or manufacturing errors, supporting shafts deflections caused by torque transmission constitute an important but predictable source of misalignments in Gear drives. In the paper, a procedure of determination of the relative spatial position of Spiral Bevel Gear supporting shafts during torque transmission will be proposed, in order to predict the relative errors of alignment between Spiral Bevel Gears. The obtained errors of alignment will be employed as initial data in the local synthesis method, for the purpose of compensating them through modification of the pinion surface microgeometry. Finally, a numerical example will illustrate the proposed procedure, as well as the advantages of its consideration in the design of advanced Spiral Bevel Gear drives in order to achieve the best contact pattern and function of transmission errors for nominal torque transmission.

  • Design, manufacture, and evaluation of prototypes of low-noise high-endurance Spiral Bevel Gear drives
    Proceedings of the ASME International Design Engineering Technical Conferences and Computers and Information in Engineering Conference - DETC2005, 2005
    Co-Authors: Alfonso Fuentes, Kenichi Hayasaka, Faydor L. Litvin, Ignacio Gonzalez-perez, Kenji Yukishima
    Abstract:

    An enhanced approach for the design of low-noise high-endurance Spiral Bevel Gear drives is presented. The contents of the paper cover the design, manufacture, stress analysis, and evaluation of prototypes of Spiral Bevel Gear drives. The proposed approach is based on the simultaneous application of both methods the local synthesis and tooth contact analysis (TCA)for design of Gear drives, application of stress analysis for investigation of formation of the bearing contact and validation of optimal design, and application of blades of different profiles (straight, parabolic, or top-rem) to avoid areas of severe contact stresses. The main goals are the improvement of the bearing contact, the achievement of a favorable shape of the function of transmission errors, reduction of the magnitude of transmission errors as the precondition of reduction of noise and vibration, and avoidance of areas of severe contact stresses for the increase of the endurance of the Gear drive. The proposed ideas have been tested by the manufacturing of prototypes of Spiral Bevel Gear drives. An example of design and optimization of a Spiral Bevel Gear drive is represented.

  • A new methodology to optimize Spiral Bevel Gear topography
    CIRP Annals - Manufacturing Technology, 2013
    Co-Authors: Emmanuel Mermoz, Julien Astoul, J. M. Linares, M. Sartor, Alain Bernard
    Abstract:

    This paper aims to present the new method developed to generate optimized Spiral Bevel Gear surfaces. Thanks to a complex non linear finite element model, the geometrical Gear meshing positions under operational loads are first precisely computed. These meshing positions are then used as inputs of a calculation process that seeks to define the best tooth surface topography. So far, this activity was based on sensitivity studies conducted directly by the designer, which led to repeat calculations whose progress was difficult to control. EUROCOPTER uses now optimization algorithms to compute automatically the surfaces of the tooth contact flanks. This approach leads to higher performances of the Gear while reducing the development time. This paper describes the new process implemented to design the tooth shape, and illustrates its interest through an example. ?? 2013 CIRP.

  • A simple and robust method for Spiral Bevel Gear generation and tooth contact analysis
    International Journal on Interactive Design and Manufacturing, 2013
    Co-Authors: Julien Astoul, Jérôme Geneix, Emmanuel Mermoz, M. Sartor
    Abstract:

    A simple and robust method to simulate Spiral Bevel Gears generating and meshing processes is proposed. In a first part, a mathematical model of universal hypoid tooth surfaces generator is formulated. It is based on Fong’s approach. The model takes into account all the kinematic motions of common CNC machine tools dedicated to hypoid Gears machining. It is general enough to enable the simulation of various hypoid Gears cutting methods such as face-hob- bing, face-milling, plunge cutting and Bevel-worm-shaped- hobbing processes. In this paper, only developments related to face-milled Spiral Bevel Gear generation are presented. We show that the results obtained are in good agreement with those of certified software. In a second part, a simple and numerically stable algorithm is proposed for unloaded tooth contact analysis. The simulation method is based on a dis- cretization of one of the two tooth flank surfaces in contact and a specific projection of the points on the opposite flank. It gives a good approximation of the contact pattern location. The accuracy of the contact point locations and computing time is directly dependent on the mesh density. However, this approach enables obtaining in a very short time sufficiently accurate results to meet the needs of designers, particularly in the preliminary stages of design. The relative displacements of the Gears can be taken into consideration. The robustness of the proposed computing process and the adjustable accuracy of the results are the two main advantages of the presented approaches.
