Claims (4)

1. Способ шлифования кулачков кулачкового вала, имеющих вогнутые боковые стороны с применением первого 7 и второго 9 шлифовальных кругов для предварительного и окончательного шлифования кулачков, причем при предварительном шлифовании на кулачке образуется промежуточный контур, отличающийся тем, что используют третий шлифовальный круг 8, диаметр которого меньше диаметра первого шлифовального круга 7 и больше диаметра второго шлифовального круга 9, соответствует примерно удвоенному радиусу вогнутых участков профиля, а его ширина меньше ширины кулачка, причем этим шлифовальным кругом 8 предварительно шлифуются вогнутые участки профиля при неподвижном кулачке 1 путем продольной подачи для образования модифицированного промежуточного контура 6.1. The method of grinding the cams of a cam shaft having concave lateral sides using the first 7 and second 9 grinding wheels for preliminary and final grinding of the cams, wherein during preliminary grinding an intermediate circuit is formed on the cam, characterized in that a third grinding wheel 8 is used, the diameter of which less than the diameter of the first grinding wheel 7 and more than the diameter of the second grinding wheel 9, corresponds to approximately twice the radius of the concave sections of the profile, and its width is less than w irins of the cam, moreover, with this grinding wheel 8, the concave sections of the profile are pre-polished with the cam 1 stationary by means of a longitudinal feed to form a modified intermediate circuit 6. 2. Станок для осуществления способа по п. 1, содержащий суппорт, перемещающимся по станине станка в радиальном направлении по отношению к шлифуемому кулачковому валу и несущим два шлифовальных шпинделя 12, 13 с шлифовальными кругами 7, 9 для предварительного и окончательного шлифования, отличающийся тем, что оба шлифовальных шпинделя 12, 13 установлены в общей шлифовальной бабке 10 таким образом, что оси шпинделей пересекаются под некоторым углом или проходят параллельно друг другу, что шлифовальная бабка 10 имеет возможность поворота вокруг оси 11, проходящей поперечно к коленчатому валу 2, и что на шпинделе 13 кроме круга 9 для предварительного шлифования установлен третий шлифовальный круг 8, диаметр которого меньше диаметра первого шлифовального круга 7 и больше диаметра второго шлифовального круга и соответствует примерно удвоенному радиусу вогнутого участка профиля кулачков 1, шлифуемых на кулачковом валу 2, а его ширина меньше ширины шлифуемого кулачка 1. 2. A machine for implementing the method according to claim 1, comprising a support moving along the machine bed in a radial direction with respect to the grinding cam shaft and bearing two grinding spindles 12, 13 with grinding wheels 7, 9 for preliminary and final grinding, characterized in that both grinding spindles 12, 13 are mounted in a common grinding head 10 so that the axis of the spindles intersect at some angle or parallel to each other, that the grinding head 10 has the ability to rotate around the axis 11 extending laterally to the crankshaft 2, and that on the spindle 13, in addition to the grinding wheel 9, a third grinding wheel 8 is installed, the diameter of which is smaller than the diameter of the first grinding wheel 7 and larger than the diameter of the second grinding wheel and corresponds to approximately twice the radius of the concave section of the cam profile 1 grinded on the cam shaft 2, and its width is less than the width of the grinded cam 1. 3. Станок по п. 2, отличающийся тем, что рабочая поверхность третьего шлифовального круга 8 выполнена конической. 3. The machine according to p. 2, characterized in that the working surface of the third grinding wheel 8 is made conical. 4. Станок по п.2, отличающийся тем, что ось шпинделя 13, несущего третий шлифовальный круг 8, при применении этого круга 8 наклонена под углом, отличающимся от Оo, по отношению к оси коленчатого вала 2.4. The machine according to claim 2, characterized in that the axis of the spindle 13 carrying the third grinding wheel 8, when using this wheel 8 is inclined at an angle different from O o with respect to the axis of the crankshaft 2.
