Description
Известны бесшпоночные снособы кренлени деталей на судовых .валах, нанример гребных винтов на гребных валах, с гндропрессоБОЙ насадкой детали на вал.Known keyless knockdowns of details on the ship’s shafts, such as propellers on the propeller shafts, with a hydraulic nozzle on the shaft.
Особенность онисываемого снособа заключаетс в том. что на вал нанос т электроизол ционное нокрытие, например стеклоткань. После этого на вал насаживают тонкостенную металлическую гильзу, защищающую нокрытие от повреждений в процессе напрессовки детали. Такое крепление гребного винта с валом устран ет гальванические взаимодействи , уменьшает электрическое поле корабл и электрохимическую коррозию между валом и насаженной на него деталью.The particularity of the on-write method is. that electrical insulation is applied to the shaft, such as fiberglass. After that, a thin-walled metal sleeve is mounted on the shaft, which protects the cover from damage during the press-fitting process. Such fastening of the propeller with the shaft eliminates galvanic interactions, reduces the electric field of the ships and electrochemical corrosion between the shaft and the part mounted on it.
На чертеже изображены детали судовых валов, скрепленные описываемым способом.The drawing shows the details of the ship shaft, fastened by the described method.
На коническую и цилиндрическую части гребного вала / до облицовки наклеивают в три сло стеклоткань 2 марки У-449 на эпоксидном клее. После выдержки и отверждени стеклопластика коническую часть гребного вала шлифуют. На конец гребного вала, покрытый изол ционным слоем, надевают стальную тонкостенную промежуточную гильЗУ 3. Гильзу с валом соедин ют гор чей или специальной гор чей посадкой.On the tapered and cylindrical parts of the propeller shaft / before lining, glass fiber 2 U-449 on epoxy glue is glued in three layers. After the fiberglass is cured and cured, the tapered portion of the propeller shaft is ground. A steel thin-walled intermediate sleeve 3 is put on the end of the propeller shaft, covered with an insulating layer. The sleeve is connected to the shaft with a hot or special hot fit.
Конусность гильзы соответствует конусности гребного вала.The taper of the liner corresponds to the taper of the propeller shaft.
Внутреннее коническое отверстие ступицы 4 гребного винта пригон ют по наружной поверхности гильзы. Гребный винт ступицей насаживают на конус гребного вала по гильзе гидропрессовым способом. Между ступице Винта и облицовкой гребного винта вала помещают резиновое уплотнительное кольцо 5. Дл электрической изол ции гребного винта от гайки 6, между ней и кормовым торцом ступицы устанавливают бетинаксовую щайбу 7.The inner conical opening of the propeller hub 4 fits over the outer surface of the liner. Propeller hub mounted on the cone of the propeller shaft on the sleeve hydropress method. A rubber sealing ring 5 is placed between the hub of the Screw and the lining of the propeller shaft. To isolate the propeller from the nut 6 electrically, a Betinax shank 7 is installed between it and the rear end of the hub.
Предмет изобретени Subject invention
Бесщпоночный способ креплени деталей на судовых валах, например гребных винтов на гребных валах, с гидропрессовой насадкой детали на вал, отличающийс тем, что, с целью устранени гальванического взаимодействи , уменьшени электрического пол корабл и электрохимической коррозии между валом и насаженной на него деталью, на вал нанос т электроизол ционное покрытие, наиример стеклоткань, и насаживают тонкостенную металлическую гильзу, - защищающую покрытие от повреждений в процессе напрессовки детали.A keyless method of fastening parts on ship shafts, for example, propellers on propeller shafts, with a hydraulic press fitting of a part on a shaft, characterized in that, in order to eliminate galvanic interaction, to reduce the electric field of the ship and electrochemical corrosion between the shaft and the part mounted on it, on the shaft an electrically insulating coating, fiberglass cloth is applied, and a thin-walled metal sleeve is inserted, which protects the coating from damage during the press-on part.
