Изобретение относитс к машиностроению и может найти применение в силовых гидроприводах.The invention relates to mechanical engineering and can be used in power hydraulic actuators.
По основному авт. СБ. М° 305299 известен гидроцилиндр, содержащий поршень со штоком, причем поршень выполнен в виде полого с обоих торцов стакана и св зан со снабженным каналом штоком при помощи упругого элемента, при этом канал сообщает ограниченную уплотнительными кольцами полость между рабочей поверхностью поршн и предварительно напр женной стенкой цилиндра с магистралью рабочей жидкости l3According to the main author. Sat M ° 305299 is known a hydraulic cylinder containing a piston with a rod, the piston being made hollow at both ends of the glass and connected to the rod provided with the channel by means of an elastic element, the channel informing the cavity bounded by sealing rings between the working surface of the piston and the prestressed wall a cylinder with a working fluid line l3
При подаче рабочей жидкости в полость между поверхностью поршн и цилиндра происходит их деформаци , при этом диаметр поршн уменьшаетс , а цилиндра увеличиваетс . Но при подаче рабочей жидкости в одну из основных полостей гидроцилиндра происходит увеличение диаметра поршн со стороны этой полости вследствиеWhen the working fluid is supplied into the cavity between the surface of the piston and the cylinder, they are deformed, and the diameter of the piston decreases and the cylinder increases. But when the working fluid is supplied to one of the main cavities of the hydraulic cylinder, the diameter of the piston increases from the side of this cavity due to
воздействи давлени рабочей жидкости на внутреннюю поверхность стенок поршн . Это приводит к трению части поршн о стенки цилиндра и как следствие к повышенному износу поршн и цилиндра. Их износ приводит к невозможности фиксации поршн в любом положении , т.е. к уменьшению долговечности .the pressure of the working fluid on the inner surface of the walls of the piston. This leads to friction of the piston on the cylinder wall and, consequently, increased wear of the piston and cylinder. Their wear leads to the impossibility of fixing the piston in any position, i.e. to reduce durability.
Цель изобретени - повышение долг говечности.The purpose of the invention is to increase the debt of bovine.
Поставленна цель достигаетс тем, что в гидроцилиндре полость стакана заполнена пористым материалом.The goal is achieved by the fact that in the hydraulic cylinder the cavity of the glass is filled with a porous material.
На чертеже изображен гидроцилиндр, продольный разрез.The drawing shows the hydraulic cylinder, a longitudinal section.
Гидроцилиндр содержит цилиндр 1, поршень 2 и шток 3. Поршень.2 св зан со штоком 3 при помощи упругого элемента t. Цилиндр 1 выполнен с размерами , обеспечивающими фиксацию поршн 2 при отсутствии давлени рабочей жидкости. Поршень 2 снабжен уплотнительными кольцами 5, ограничивающимиThe hydraulic cylinder comprises a cylinder 1, a piston 2 and a rod 3. A piston 2 is associated with the rod 3 by means of an elastic element t. The cylinder 1 is made with dimensions that ensure the fixation of the piston 2 in the absence of pressure of the working fluid. The piston 2 is provided with sealing rings 5, limiting
