    Journal of Mechanical Engineering and Automation 2020, 9(1): 1-8 DOI: 10.5923/j.jmea.20200901.01 Verification of the Dynamic Characteristics of an Epicyclic Gear Train Using Epicyclic Gear Train and Torque Apparatus Mauton Gbededo1,2,*, Chukwuemeke Onyenefa2, Matthew Arowolo1 1Department of Mechatronics Engineering, Federal University, Oye-Ekiti, Nigeria 2Department of Mechanical & Biomedical Engineering, Bells University of Technology, Ota, Nigeria Abstract An epicyclic gear train consists of two gears, mounted so that the center of one gear revolved around the center of the other. A carrier connects the centers of the two gears and it rotates to carry one gear, called the planet gear or planet pinion, around the other, called the sun gear or sun wheel. The planet and sun gears were meshed so that their pitch circles rolled without slipping. A point on the pitch circle of the planet gear traced an epicycloid curve. This paper deals with analysis and verification of dynamic characteristics of an epicyclic gear train using the gear train and torque apparatus. The apparatus was installed in the Engineering lab while taking adequate safety precautions to ensure accurate collection of data. A record of the input, holding and output at various speed of the gear system were taken. At the end of the experiment, gear ratio, speed ratio and torque relationship of the epicyclic gear train were obtained. The experimental results were compared to the analytical data from various calculations using respective governing equations. It was observed that the experimental results were similar to the analytical data obtained for the speed ratio and torque relationship with a maximum 1.11% deviation between the two methods for torque relationship and 1.6% for the speed ratios, which were due to some frictional and mechanical losses in the belt and gear system.

  • Novel Designs and Geometry for Mechanical Gearing
    Novel Designs and Geometry for Mechanical Gearing by Erasmo Chiappetta School of Engineering, Computing and Mathematics Oxford Brookes University In collaboration with Norbar Torque Tools ltd., UK. A thesis submitted in partial fulfilment of the requirements of Oxford Brookes University for the degree of Doctor of Philosophy September 2018 Abstract This thesis presents quasi-static Finite Element Methods for the analysis of the stress state occurring in a pair of loaded spur gears and aims to further research the effect of tooth profile modifications on the mechanical performance of a mating gear pair. The investigation is then extended to epicyclic transmissions as they are considered the most viable solution when the transmission of high torque level within a compact volume is required. Since, for the current study, only low speed conditions are considered, dynamic loads do not play a crucial role. Vibrations and the resulting noise might be considered negligible and consequently the design process is dictated entirely by the stress state occurring on the mating components. Gear load carrying capacity is limited by maximum contact and bending stress and their correlated failure modes. Consequently, the occurring stress state is the main criteria to characterise the load carrying capacity of a gear system. Contact and bending stresses are evaluated for multiple positions over a mesh cycle of a contacting tooth pair in order to consider the stress fluctuation as consequence of the alternation of single and double pairs of teeth in contact. The influence of gear geometrical proportions on mechanical properties of gears in mesh is studied thoroughly by means of the definition of a domain of feasible combination of geometrical parameters in order to deconstruct the well-established gear design process based on rating standards and base the defined gear geometry on operational and manufacturing constraints only.

  • Basic Fundamentals of Gear Drives
    Basic Fundamentals of Gear Drives Course No: M06-031 Credit: 6 PDH A. Bhatia Continuing Education and Development, Inc. 22 Stonewall Court Woodcliff Lake, NJ 07677 P: (877) 322-5800 [email protected] BASIC FUNDAMENTALS OF GEAR DRIVES A gear is a toothed wheel that engages another toothed mechanism to change speed or the direction of transmitted motion. Gears are generally used for one of four different reasons: 1. To increase or decrease the speed of rotation; 2. To change the amount of force or torque; 3. To move rotational motion to a different axis (i.e. parallel, right angles, rotating, linear etc.); and 4. To reverse the direction of rotation. Gears are compact, positive-engagement, power transmission elements capable of changing the amount of force or torque. Sports cars go fast (have speed) but cannot pull any weight. Big trucks can pull heavy loads (have power) but cannot go fast. Gears cause this. Gears are generally selected and manufactured using standards established by American Gear Manufacturers Association (AGMA) and American National Standards Institute (ANSI). This course provides an outline of gear fundamentals and is beneficial to readers who want to acquire knowledge about mechanics of gears. The course is divided into 6 sections: Section -1 Gear Types, Characteristics and Applications Section -2 Gears Fundamentals Section -3 Power Transmission Fundamentals Section -4 Gear Trains Section -5 Gear Failure and Reliability Analysis Section -6 How to Specify and Select Gear Drives SECTION -1 GEAR TYPES, CHARACTERISTICS & APPLICATIONS The gears can be classified according to: 1. the position of shaft axes 2.

Box 12200, FI-00076 Aalto, Finland e-mail: [email protected] Coordinating functional parts to operate in concert is essential for machinery. In gear trains, meshed gears are compactly interlocked, working together to impose rotation or translation. In photosynthetic systems, a variety of biological entities in the thylakoid membrane interact with each other, converting light energy into chemical energy. However, coordinating individual parts to carry out regulated and coordinated motion within an artificial nanoarchitecture poses great challenges, owing to the requisite control on the nanoscale. Here, we demonstrate DNA-directed nanosystems, which comprise hierarchically-assembled DNA origami filaments, fluorophores, and gold nanocrystals. These individual building blocks can execute independent, synchronous, or joint motion upon external inputs. The dynamic processes are in situ optically monitored using fluorescence spectroscopy, taking advantage of the sensitive distance-dependent interactions between the gold nanocrystals and fluorophores positioned on the DNA origami. Our work leverages the complexity of DNA-based artificial nanosystems with tailored dynamic functionality, representing a viable route towards technomimetic nanomachinery. 1 Machines are built with multiple parts, which can work together for a particular function.
