Abstract
Изобретение относитс к области горной нромышленности и позвол ет повысить надежность креплени насадки (Н) 2 и герметизации узла. Конусна Н 2 установлена в конусном гнезде корпуса посредством упругого фиксирующего элемента, размеихенного между коническими повер.хност ми Н 2 и гнезда. При этом фиксируюихий элемент выполнен в виде конусной втулки (KB) 3 с поперечными порез ми из материала , твердость которого ниже твердости материала гнезда. Переход большего основани Н 2 к боковой поверхности выполнен скругленным. Диаметр окружности сопр жени поверхности скруглени и плоской торцовой поверхности Н 2 равен диаметру проходного сечени KB 3. Установка KB 3 в гнездо осуществл етс за счет предварительного сжати наибольшего диаметра KB 3 до величины входного отверсти гнезда. После установки KB 3 в гнездо Н 2 сферической поверхностью упираетс и приФ жимаетс к ней. При прохождении через (О Н 2 промывочной жидкости Н 2 будет смещатьс вдоль оси и произойдет закрепление KB 3 с большим усилием. 2 ил.The invention relates to the field of the mining industry and improves the reliability of fastening the nozzle (H) 2 and sealing the assembly. The cone H 2 is installed in the conical socket of the body by means of an elastic fixing element, spaced between the conical surfaces of the H 2 and the socket. In this case, the fixed element is made in the form of a tapered bushing (KB) 3 with transverse cuts made of a material whose hardness is lower than the hardness of the nest material. The transition of the larger base H 2 to the side surface is rounded. The diameter of the circumferential interface of the rounding surface and the flat end surface H 2 is equal to the diameter of the KB 3 bore. The KB 3 is inserted into the socket by pre-compressing the largest diameter KB 3 to the size of the socket inlet. After installing KB 3 into the H 2 slot, the spherical surface abuts and presses against it. When passing through (ОH 2 the washing liquid H 2 will shift along the axis and KB 3 will be fixed with great effort. 2 Il.
