Description

В известных конструкци х электрических машин взрывонепроницаемость подшипникового узла обеспечиваетс специальным взрывозащитным устройством, вл ющимс самосто тельным узлом, не св занным с подшипником качени . Однако такое взрывозащитное, устройство громоздко и сложно по своей конструкции , что приводит к увеличению габаритов , веса и стоимости электрических машин.In the known structures of electric machines, the impermeability of the bearing assembly is ensured by a special explosion-proof device, which is an independent assembly that is not associated with the rolling bearing. However, such an explosion-proof device is cumbersome and complicated in its design, which leads to an increase in size, weight and cost of electric cars.
Цель изобретени - упрощение конструкции и технологии изготовлени взрывонепроницаемых электрических машин. Это достигаетс тем, что в качестве элемента взрывозащиты используют роликовый игольчатый подшипник качени без сепаратора.The purpose of the invention is to simplify the construction and technology of manufacturing flameproof electric machines. This is achieved by using a roller roller bearing without a separator as an element of explosion protection.
Если указанный подшипник установлен, например , во взрывозащитном электродвигателе, то дл такого подшипникового узла не требуетс установки дополнительного взрывозащитного устройства, потому что сам игольчатый подшипник взрывонепронигцаем, так как длина и сечение зазоров, образованных наружным и внутренним кольцами и заключенными между ними роликами-иголками, достаточны дл гашени пламени взрывоопасных смесей. Таким образом, подшипник служит одновременно и подшипником и взрывозащитным устройством. Взрывонепроницаемость по наружному и внутреннему контурам обеспечиваетс известной плотной посадкой подшипника на вал и в гнездо корпуса. При износе подшипник замен ют новым.If the specified bearing is installed, for example, in an explosion-proof electric motor, then an additional explosion-proof device is not required for such a bearing unit, because the needle bearing itself is explosive, since the length and cross section of the gaps formed by the outer and inner rings and the needle rollers between them sufficient to extinguish the flame of explosive mixtures. Thus, the bearing serves as both a bearing and an explosion-proof device. The explosion-proofness of the outer and inner contours is ensured by the known tight fit of the bearing on the shaft and in the housing housing. When worn, the bearing is replaced with a new one.
