Subject: headcenter, spinning rotation of the crusher tech. A problem which is frequently encountered in cone and gyratory crushers is the fact that in starting up a crusher and with the crusher substantially under no load, the crusher head will not only gyrate as the eccentric sleeve rotates, but will also tend to rotate with the eccentric sleeve due to the bearing drag between the rotating eccentric sleeve and the crusher head. Thus, for example, the eccentric sleeve may be rotating at some speed such as 300 r.p.m., and the bearing drag between the unloaded crusher head and the rotating eccentric sleeve may be such that the crusher head or headcenter will rotate at a speed less than that of the rotating eccentric sleeve. This spinning rotation of the headcenter in the so-called idling direction of rotation is undesirable since it causes the rocks and stones which are being loaded into the crusher to be thrown about and even to be thrown out of the crusher.In accordance with the invention, the crusher is provided with means for reducing spinning of the crusher head which is effective substantially only during the no load or idling operation of the crusher. According to the invention, this anti-spin function is associated with the dust seal in a manner which will now be described. Как правильно перевести по дробилке следующие термины - headcenter, spinning rotation, anti-spin function, reducing spinning of the crusher? |

это не об этом? "Вращение подвижного конуса вокруг своей оси явление нежелательное, так как приводит к излишним динамическим нагрузкам в момент загрузки материала в камеру дробления, поэтому в некоторых конструкциях конусных дробилок предусмотрены специальные тормозные устройства, препятствующие вовлечению подвижного конуса во вращение." http://forpsk.ru/index.php/stati/oborudovanie/141-konusnaya-drobilka-klassifikatsiya-printsip-dejstviya-i-konstruktsiya |

Что ж, тогда предлагаю свои варианты тех терминов. Поправьте меня, еслим что-то не так. headcenter - основной центр Подойдет? |
