To the question of optimal design of worm-cylindrical gearboxes

Abstract

The problem of multicriteria optimal design of a worm-cylinder reducer with a lower location of the Archimedean worm is considered. A designmathematical model of a reducer has been developed, with the use of which, using the example of parametric optimization of a specific gearbox, effective optimization parameters have been determined and the problem of the optimal distribution of the overall gear ratio between its stages has been investigated. To solve this problem, we used the method of admissible sets based on the PSI design ideology. The results of numerical analysis of the information space of the reducer under study, in particular, the analysis of the influence of the number of gear teeth and material for the production of cylindrical wheels are given. To provide a crankcase lubrication system for gears and reduce the height of the type of reducers in question, an algorithm is proposed for calculating the cylindrical gear. The existing recommendations on the distribution of gear ratios over the reducer stages are analyzed and recommendations for the selection of optimal rational design solutions for the reducer under consideration are given, with different limitations on the quality criteria. Conclusions are drawn from the results of the studies. The developed software implementation of the proposed design methodology can be used as a tool for optimally-rational design of stepped gear reducers.

Розглянута задача багатокритеріального оптимального проектування ступінчастого черв׳ячно-циліндричного редуктора з нижнім розташуванням архімедова черв’яка. Розроблена проектно-математична модель редуктора і на прикладі параметричної оптимізації визначеного редуктора за обраними критеріями якості визначені ефективні параметри оптимізації та досліджена задача розподілу загально передаточного числа редуктора. Для вирішення оптимізаційної задачі застосовується метод допустимих множин. Наведені результати чисельного аналізу інформаційної множини проектованого редуктора. Для забезпечення картерної системи мащення і зменшення висоти редуктора запропонована зміна алгоритму розрахунку циліндричної передачі. Проаналізовані рекомендації по розподілу передаточних чисел по ступеням редуктора та наведені рекомендації до вибору оптимально-раціональних проектних рішень при різних обмеженнях на критерії якості. Зроблені висновки по результатам проведених досліджень.
