Description
Известен гидростатодипамический нодшипник дл валков прокатных станов, содержащий корпус, полость высокого давлени рабочей жидкости, вкладыш цапфы валка и каналы но длине подшипника, соедин ющие полость с рабочей поверхностью вкладыша.A hydrostatodipamic bearing for rolls of rolling mills is known, comprising a housing, a high-pressure cavity of the working fluid, a roll journal liner and channels, but the length of the bearing, connecting the cavity to the liner working surface.
Предлагаемый подшипник отличаетс тем, что каналы, соедин ющие полость высокого давлени рабочей жидкости с рабочей поверхностью вкладыша размещены многор дно по дуге рабочей зоны подшипника.The proposed bearing is characterized in that the channels connecting the high-pressure cavity of the working fluid with the working surface of the liner are arranged multi-way along the arc of the working area of the bearing.
Это позвол ет выравнивать нагрузочные и температурные характеристики на рабочей поверхности вкладыша.This makes it possible to equalize the load and temperature characteristics on the working surface of the liner.
На фиг. 1 показан ноперечный разрез подшипника; на фиг. 2 - разрез по А-Л и Б-Б на фиг. 1; на фиг. 3 - эпюра распределени давлени в рабочей зоне подшипника, обозначенной углом 2 j6.FIG. 1 shows a cross section of the bearing; in fig. 2 shows a section along A-L and BB in FIG. one; in fig. 3 is a plot of the pressure distribution in the working area of the bearing, indicated by the angle 2 j6.
Подшипник состоит из корпуса / и вкладыша 2, в котором установлена папфа 3 валка прокатного стана.The bearing consists of a body / and liner 2, in which papf 3 rolls of the rolling mill are installed.
В корпусе / и вкладыше 2 размещены каналы 4 малого диаметра, распределенные по рабочей зоне подшипника, через которые в нее подаетс из полости 5 высокого давлени рабоча жидкость.In the housing / and liner 2, small-diameter channels 4 are placed, distributed over the working area of the bearing, through which the working fluid is supplied to it from the high-pressure cavity 5.
Посредством каналов 4 эпюра давлений 6 приобретает пр моугольный характер.By means of the channels 4, the pressure profile 6 acquires a rectangular character.
Во врем работы подшипника перекосы цапфы валка не вли ют на расход и давление рабочей жидкости в рабочей зоне, так как с изменением сечений по кра м рабочей зоны истекающа через каналы жидкость создает поле высокого давлени по всей рабочей зоне.During the operation of the bearing, distortions of the roller trunnion do not affect the flow and pressure of the working fluid in the working area, because with changing sections along the edges of the working area, the fluid flowing through the channels creates a high pressure field throughout the working area.
Предлагаемый подшипник обладает гидродинамическим качеством, и при аварии в сети высокого давлени , т. е. при спаде давлени , он работает как гидродинамический подшипник с эпюрой давлени 7.The proposed bearing has a hydrodynamic quality, and in the event of an accident in a high-pressure network, i.e. during a pressure drop, it works as a hydrodynamic bearing with a pressure profile 7.
Подшипник не требует специальной системы дросселировани расхода рабочей жидкости .The bearing does not require a special system for throttling the flow rate of the working fluid.
Предмет изобретени Subject invention
Гидростатодинамический подшипник дл валков прокатных станов, содержащий корпус, полость высокого давлени рабочей жидкости , вкладыш цапфы валка и кана,1ы по длине подшипника, соедин ющие полость с рабочей Hydrostrodynamic bearing for rolling mill rolls, comprising a housing, a high-pressure cavity of the working fluid, a roll journal and a canal liner, 1i along the length of the bearing, connecting the cavity with the working
25 поверхностью вк.падыша, отличающийс тем. что, с целью выравнивани нагрузочных и температурных характеристик на рабочей поверхности вкладыша, упом нутые каналы многор дно размещены по дуге рабочей зоны подщипника .25 surface of the breath, characterized in that. that, in order to equalize the load and temperature characteristics on the working surface of the liner, the said channels are multi-bottom placed along the arc of the working area of the sub-liner.
