Description
Известны способы шлифовки и полировки гребных винтов с применением абразивной суспензии.Known methods of grinding and polishing propellers with the use of abrasive slurry.
Отличительной особенностью описываемого способа, вл етс то, что он обеспечивает смывание винта потоком суспензии, создаваемым самим винтом аналогично тому, как при работе винта создаетс омывающий его поток воды.A distinctive feature of the described method is that it ensures the washing off of the screw by a stream of suspension created by the screw itself in the same way that a screw is washed by a stream of water.
Целью такого способа вл етс повышение к.п.д. винтов.The purpose of this method is to increase the efficiency. screws.
Предлагаемое устройство дл осуществлени способа представл ет собою цилиндрическую насадку, монтированную в резервуаре с абразивной суспензией и служащую дл помещени в ней винта при его шлифовке и полировке.The proposed apparatus for carrying out the method is a cylindrical nozzle mounted in a tank with an abrasive slurry and used to place a screw in it during grinding and polishing.
На фиг. 1 изображено предлагаемое устройство в осево.м разрезе; па фиг. 2 - устройство в разрезе по А-А на фиг. 1.FIG. 1 shows the proposed device in axial m section; pas figs. 2 shows the device in section along A-A in FIG. one.
Гребной винт / укрепл етс па шпинделе 2 станк;а и погружаетс в полый цилиндр 3, установленный на радиально расположенных перегородках 4 резервуара 5, наполненного абразивной суспензией. При вращении шпиндел с укрепленным на нем винтом суспензи внутри цилиндра устремл етс вниз и выдавливает нижние слои, которые поднимаютс по отсекам между перегородками 4 вверх.The propeller is fastened to the spindle 2 of the machine, and then it is immersed in a hollow cylinder 3 mounted on radially arranged partitions 4 of the tank 5 filled with abrasive slurry. As the spindle rotates with the screw mounted on it, the suspension inside the cylinder rushes down and squeezes the lower layers, which rise along the compartments between the partitions 4 upwards.
Таким образом в резервуаре происходит непрерывна циркул ци суспензии, шлифующей и полирующей лопасти винта.Thus, continuous suspension of the grinding and polishing blade of the screw occurs in the tank.
Наиболее интенсивно процесс шлифовки и полировки происходит на нагнетающей стороне винта. С целью равномерной обработки обеих сторон лопасти винта, его поворачивают на 180°, после чего обрабатываетс втора сторона лопасти.The most intensive process of grinding and polishing occurs on the pressure side of the screw. For the purpose of uniform processing of both sides of the blade of the screw, it is turned through 180 °, after which the second side of the blade is processed.
Предмет изобретени Subject invention
1. Способ шлифовки и полировки гребных винтов с применением абразивной суспензии, отличаюшийс тем, что, с целью осуществлени взаимодействи винта и суспензии, аналогичного взаимодействию винта и воды, дл повышени к.п.д. винта, самим обрабатываемым винтом Создают поток суспензии, омывающий винт аналогично тому, как его омывает при его работе поток воды.1. A method of grinding and polishing propellers using an abrasive slurry, characterized in that, in order to effect the interaction of a screw and a suspension, similar to the interaction of a screw and water, to increase the efficiency of the screw, by the screw itself. Create a suspension flow washing the screw in the same way as a stream of water washes it during its operation.
