On Fewer Teeth Gear Processing Technology And Equipment

Fewer teeth gear drive technology breaks the restriction of the least number of teeth in the traditional gear design theory, and the teeth number is down to 2. Based on the technology, involute fewer teeth gear gearing has a higher single-stage transmission ratio, higher efficiency, higher carrying capacity, more compact structure and lighter weight. It is suitable for small and medium power transmission, where the size is restricted and the transmission ratio is higher.It is these advantages make involute fewer teeth gearing more and more, but its applications are not so widespread. The biggest obstacle restricting its application is the machining of fewer teeth gear.In Y38 type hobbing machine, processing fewer teeth gear on gear hobbing machine, due to machine tool spindle and the table of the transmission ratio is quite small, relatively large machine tool drive, drive chain is longer, lower transmission efficiency drive system makes the machine tools, transmission resistance is increased, since the machine will appear locking phenomenon does not work. Therefore, theoretically speaking, gear hobbing machine can not process fewer teeth gear, which gear to the application of fewer teeth gear is a big difficulty.Purpose and significance of this paper is:fewer teeth gear in the absence of special gear machine case, fewer teeth gear tooth surface processing technology, and Y38-type hobbing bed transformation of few teeth gears.Fewer teeth gear on the gear tooth surface processing technology and equipment have been studied, mainly carried out the following:fewer teeth gear tooth surface processing technology of transformation of Y38 type hobbing machine bed ways, experimental machining gear teeth less and less gear teeth Detection and analysis of machining errors.
