| Research Abstract |
In the second part of my specialization (November, 2013 November, 2014) the process of development of mathematical models, oriented to the construction of adequate algorithms for the functional and technological analysis and synthesis of spatial mechanical motion transformers continue. The concept, developing a strategic opportunity to create innovative solutions to spatial (hyperboloid) transmissions is offered to the scientific society. Without no doubt it is shown that this can be done by application and development of modern scientific field in the "Theory of Gearing", related to the introduction into the processes of synthesis and computer design of the theoretical primitives of the mathematical models, which are named from the scientists - "pitch configurations"
Theoretical (including terminology), analytical and software expediency from introducing these characteristics determines the demand and finding innovative solutions by creating hyperboloid gears with internal meshing. Up

to now, this class of spatial transmissions is not applied in the techniques. The interest of researchers to create these spatial transmissions is driven by their higher exploitation properties (loading capacity and smoothness of the transformation motions) compared to the analogical ones of the conventional hyperboloid transmissions with external meshing. Research of this type is presented in the publications cited in section 5.1 of the report. There are illustrated orthogonal face small modulemicro-transmissions designed for incorporation into robot hand from Kawasaki and Mouri Laboratory - Gifu University, as an alternative to plane bevel gears with straight teeth - element of the robot hand's construction. It is shown that the developed face gear sets of type "Helicon" are on the border between hyperboloid gear with internal gearing and the same one with external gearing. These new developed gear transmissions have also certain innovative features. For the treated from this report period of time it is realized a study of spatial rack drives, which is send for participation in The 8th International Symposium- KOD 2014 -MACHINE AND INDUSTRIAL DESIGN IN MECHANICAL ENGINEERING, 12 - 15 June 2014.
This study is realized in accordance with the current plan of specialization and it is dedicated to the mathematical models and based on them algorithms for synthesis. Here it should be mentioned that in specialized literature there are some structural and constructive solutions to robotic systems, functionally analogous to the objects of study in the Laboratory of Kawasaki and Mori-Gifu University. In these scientific sources spatial rack drives are used as motion transformers. The modeled, synthesized and software generated spatial rack drives (according to the authors of the publication shown in section 5.3.) have competitive exploitation characteristics : higher loading capacity, improved smoothness of motions transformation and possibility for regulation of the backlash with a simple technical methods. In the other two publications (stated in Sections 5.2 and 5.4. in this report) are summarized principles, features and applied approaches for the organization of computer programs designed and implemented in Bulgaria for the synthesis of gears with facie meshing -types "Spiroid" and "Helicon". The main characteristics of the mathematical models which are basis for the developed computer programs are shown. There are short listed again the main criteria used for quality control of gear droves, depending on their application in the process of their optimization synthesis. Less
