Zastosowanie metody optycznej w ocenie cech geometrycznych nieokr?g?ych kó? pasowych

摘要

W artykule przedstawiono problematyk? oceny dok?adno?ci odwzorowania zaprojektowanych cech geometrycznych nieokr?g?ych kó? pasowych stosowanych w nierównobie?nych przek?adniach ci?gnowych. Badania przeprowadzono za pomoc? optycznego systemu pomiarowego ATOS. Scharakteryzowano procedur? pomiaru I aparatur? badawcz? zastosowan? w procesie digitalizacji przyk?adowych kó? nieokr?g?ych. Zilustrowano przeprowadzone badania eksperymentalne oraz zawarto przyk?adowe wyniki pomiarów. W podsumowaniu opisano uzyskane wyniki badań optycznych kó? pasowych nieokr?g?ych wykonanych ró?nymi metodami kszta?towania.%The issue of estimation of mapping accuracy of designed geometrical features of non-classical machine elements, such as non-circular cogbelt pulleys, is presented in the paper. Such elements are applied in uneven-running strand transmissions with cogbelt. The characteristic feature of these transmissions is the possibility of obtaining the periodically variable kinematic features such as velocity, gear ratio. The genesis of origin of transmissions and illustration of designed and manufactured test stand are given in introduction (Fig. 1). Next manufacturing methods of exemplary non-circular cogbelt pulleys are presented (Fig. 2). The measuring procedure and testing equipment used in digitalization process of exemplary non-circular gears are described in the next part of paper (Fig. 3). Presented illustrations show the result of comparison of solid model, which was a basis for elaboration of manufacturing process of cogbelt pulleys, and shell model, which was obtained as a result of digitalization with the use of ATOS scanner - GOM manufacturer (Fig. 4-6). Applied research method of geometrical features distinguishes itself by many advantages in comparison with contact methods in scope of delivery time of results of measurement. The results of investigation will be used for analysis of manufacturing accuracy of transmission elements, which are produced with the use of manufacturing methods mentioned in paper.
