Possible ways of reducing the number of gears in universal gear units

Abstract

This paper analyzes possibilities of reducing the number of necessary gears in thefamily of universal motor gear reducers with helical gears, since both the production andstorage of a large number of different gears cost a lot and impose a great burden for any gearmanufacturer, as it can be seen from literature [1,2] that focuses on this problem. The paperparticularly emphasizes the necessity of narrowing down the assortment of gear reducers andthe possibility of changing the design solution between the pinion and the electric motor asthey represent the basic possibilities for reducing the number of necessary gears. The paperalso points out the need for a special selection of preferred gear ratios and correspondinggears as one of the possibilities for reducing the total number of gears. This can certainlyresult in faster delivery of a gearbox with the preferred gear ratio.
