Tooth shapes of helical gears manufactured by formed grinding with radial displacement crowning

摘要

The principle of formed-wheel grinding with a crowning process for helical gears and the construction and operation of the gear grinding machine to be enplaned in this process are explained. Tooth shapes of the helical gears manufactured by thiscrowning process are discussed on the basis of the results of a numerical calculation. Some grinding method is proposed for compensating the profile errors caused by this crowning method.
