  • a new design of tooth profiles increases Synchronous Belt s fatigue life
    ASME 2008 International Mechanical Engineering Congress and Exposition, 2008
    Co-Authors: Jianhua Guo, Hongyuan Jiang, Gang Han, Hui Yan
    Abstract:

    Synchronous Belt and its driving pulley have non-conjugate tooth profiles. Because of non-conjugate motion and polygon effect, interference occurs during incomplete meshing, resulting in excessive wear and tear at tooth-root, which are the main forms of failure of Synchronous Belts. Tooth cracking also results from uneven stress distribution and/or increased maximal stress. In addition to discovering better materials to increase the strength of the Belt’s teeth, optimization of the geometry of tooth profiles of Belt and pulley to decrease the maximum tooth-root stress and to reduce interference during meshing is critical in improving the carrying capacity and increasing the Belt’s life span. In the present study we proposed a new design of Synchronous Belt’s and pulley’s tooth profiles, modifying several key geometric parameters commonly used in Synchronous Belts’ designs. Applying the conformal mapping function and the theory of plane elasticity we systemically investigated the distribution of stress and distortion at the Belt’s and pulley’s teeth of varying geometric parameters and analyzed the interference during meshing using an approach to investigating tooth profiles of non-constant pitch diameter. Finite Element Analysis showed that with the same load the maximum principal stress values of Belt teeth in complete meshing in our design (STSB) were 54.4% and 67.8% of that of HTD (by Uniroyal) and STPD (by Good Year) Belts with an 8 mm pitch commonly used in automobiles, respectively. The uneven distribution of stress along the edge of tooth profile was reduced, and the interference during meshing minimized with our design. We then experimentally tested Belts made of the same materials with the three designs manufactured by the same factory. The Belts were tested in the enclosed type of testing machine for Synchronous Belt’s fatigue-life, power = 6.5 kW and speed = 1500 r/min with test Belt tension at 400 N. The fatigue lives of the Belts (n = 5 each group) were 988 ± 36, 439 ± 21 and 665 ± 22 hours (mean ± SD) for STSB, HTD and STPD Belts (p<0.0001), respectively, demonstrating the superiority of our design. We anticipate that the new design will have wide applications not limited to the automobile industry.Copyright © 2008 by ASME

  • experimental and numerical study of heat transfer through a Synchronous Belt transmission type at10
    Applied Thermal Engineering, 2017
    Co-Authors: Sidi Mohammed Merghache, Mohamed El Amine Ghernaout
    Abstract:

    In most industrial applications, the re-use of Belts in power transmissions continues to increase and invade the market especially in automobiles where various types of Belts are used. For this purpose, the Belt manufacturers are aware of the importance and the valuable advantages of this transmission member and put all their efforts to develop and improve its geometrical and mechanical characteristics in order to achieve an optimal service life. Indeed, this article is devoted to an experimental and numerical thermal study of a toothed Belt transmission type AT10. The tests were carried out on an original derrick of test for the purpose of measuring Belt and pulley temperatures, detector devices and data acquisitions will also be described. Further, we have developed a model that calculates the heat flux through our pulley-Belt transmission. The results will be synthesized to make a comparison between two thermal fluxes. The first is determined from our mathematical model and the second is calculated using the thermal simulation of this Belt pulley transmission. Finally, a discussion of the results, which will allow us to fully understand this thermal phenomenon.

  • interactive design for additive manufacturing a creative case of Synchronous Belt drive
    International Journal on Interactive Design and Manufacturing (ijidem), 2018
    Co-Authors: Hu Fuwen, Cheng Jiajian, He Yunhua
    Abstract:

    As a digital and direct manufacturing technology, additive manufacturing (AM) presents a powerful and unrestrained revolution for creative design. However the breakthrough in manufacturing technology is yet to be followed by a breakthrough in design. Firstly, the state-of-the-art overview of the existing design methods for AM is presented. Furthermore, as part of a fully 3D printed robot we envisioned, this work mainly put forward a novel Synchronous Belt drive as an illuminating case with the potential and constraints of AM. After capturing the flexibility based on shape innovation, a new type of continuous trapezoidal tooth Belt transmission without matrix was designed. Next, using the nonlinear finite elements method, the effect laws of Belt’s parameters such as tooth height, tooth width, wedge angle and Belt thickness were studied on the carrying capacity of Belt transmission with pre-tensioning. Moreover, a new type of Synchronous Belt and timing pulleys were made via the 3D printing process of fused deposition modeling with the flexible polylactic acid (PLA) material. Lastly, a driving test was carried out and the experimental results showed that the presented 3D printed trapezoidal tooth Belt transmission was stable, and could meet the requirements of low speed, small power transmission, especially apt to digital design and customization. This work completely demonstrates the intrinsic nature of digital design, interactive design and custom design from/with/for AM, as well as the ever-expanding room for innovation.
