Abstract
Способ обработки пористого вкладыша газостатического подшипника, включающий ступенчатую сушку заготовки из заболонной части древесины в сушильном шкафу с автоматическим регулированием температуры, отличающийся тем, что обработанная до нужной геометрической формы заготовка из заболонной части древесины предварительно вываривается в течение 8 часов в резервуаре с раствором поваренной соли, при этом концентрация соли в растворе составляет от 50% до 80%, после чего торцы заготовки замазываются клейким раствором, закупоривающим торцы заготовок, затем производится сушка в сушильном шкафу в два этапа, при этом первый этап состоит из следующих операций: сушка первые 4 часа при температуре 140°С, затем сушка в течение последующих 3 часов при температуре 180°С, затем сушка 1 час при температуре 220°С, а потом охлаждение заготовки в сушильном шкафу в течение 2 часов, второй этап сушки происходит при температуре 110°С в течение 8 часов, при этом через каждые 2 часа заготовка переворачивается, а по истечению второго этапа сушки заготовка вылеживается и остывает в сушильном шкафу в течение 2 часов.A method for treating a porous liner of a gas-static bearing, including stepwise drying of a billet from the sapwood part of the wood in an oven with automatic temperature control, characterized in that the billet made from the sapwood part of the wood is processed to the desired geometric shape and preliminarily boiled for 8 hours in a tank with sodium chloride solution, the salt concentration in the solution is from 50% to 80%, after which the ends of the workpiece are smeared with an adhesive solution that clogs the ends of the lamb, then drying in an oven in two stages, the first stage consists of the following operations: drying the first 4 hours at a temperature of 140 ° C, then drying for the next 3 hours at a temperature of 180 ° C, then drying for 1 hour at a temperature 220 ° C, and then the workpiece is cooled in the oven for 2 hours, the second drying stage occurs at 110 ° C for 8 hours, and after every 2 hours the workpiece is turned over, and after the second drying stage the workpiece is aged and cooled down oven for 2 hours s.
