Изобретение относитс к области гидромашиностроени .The invention relates to the field of hydraulic engineering.
Известны механизмы поворота лопаток направл ющего аппарата гидротурбины, содержащие рычаги, соединеппые с лопатками при помощи клиновых цилиндрических шпонок. Такие шпонки обеспечивают фиксацию рычага на лопатке с нат гом, но вместе с тем металлоемки и трудоемки в изготовлении (особенно шлифование при обработке клиновой поверхности ).Mechanisms are known for rotating the blades of a guide vane of a hydroturbine, which contain levers connected to the blades by means of wedge cylindrical keys. Such keys ensure that the lever is fixed on the paddle with tension, but at the same time it is metal consuming and laborious in manufacturing (especially grinding when machining a wedge surface).
Дл уменьшени металлоемкости и трудоемкости изготовлени механизма, а также упрощени сборки узла рычаг-лопатка в предлагаемом механизме шпонки выполнены в виде разрезанной вдоль оси втулки с коническим отверстием и размещенного внутри втулки конического штифта, бокова поверхность которого сопр жена с внутренней поверхностью втулки.To reduce metal consumption and laboriousness of manufacturing the mechanism, as well as to simplify assembly of the node, the blade lever in the proposed mechanism the keys are made in the form of a sleeve with a tapered bore along the axis and a tapered pin placed inside the sleeve, the side surface of which is associated with the inside surface of the sleeve.
На фиг. 1 изображен описываемый механизм , продольный разрез; на фиг. 2 - то же, поперечный разрез по А - А на фиг. 1.FIG. 1 shows the described mechanism, a longitudinal section; in fig. 2 is the same, the cross section along A - A in FIG. one.
Рычаг 1 механизма надет на цапфу 2 поворотной лопатки и закреплен при помощи шпонки, выполненной в виде разрезанной вдоль оси втулки 3. Втулка установлена вThe lever 1 of the mechanism is mounted on the pin 2 of the rotary blade and secured with a key, made in the form of a sleeve 3 cut along the axis. The sleeve is installed in
совместно выполненном в рычаге и цапфе отверстии . В коническом отверстии втулки размещен конический штифт 4 с гайкой 5. Навинчива гайку на штнфт, последний вт гивают во внутреннее отверстие втулки 3, создава нат г соединени .jointly made in the lever and the pin hole. A tapered pin 4 with a nut 5 is placed in the conical bore of the bushing. Screw the nut on the pin, the latter is pulled into the internal bore of the bushing 3, creating a tension connection.
Предмет изобретени Subject invention
Механизм поворота лопаток направл ющего аппарата гидротурбины, содержащий рычаги , соединенные с лопатками при помощи составных шпонок, отличающийс тем, что, с целью уменьшени металлоемкости и трудоемкости изготовлени , шпонки выполнены в виде разрезанной вдоль оси втулки с коническим отверстием и размещенного внутри последней штифта, бокова поверхность которого сопр жена с внутренней поверхностью втулки.The mechanism of rotation of the blades of the guide vane of the turbine, containing levers connected to the blades by means of composite dowels, characterized in that, in order to reduce metal consumption and labor intensity, the dowels are cut as a sleeve along the axis of the sleeve with a tapered bore and placed inside the last pin the surface of which is mated with the inner surface of the sleeve.
