Изобретение относитс к области создани антифрикционных материалов.This invention relates to the field of creating anti-friction materials.
Известны пресс-материалы на основе эпоксидных смол со стеклотканью имеющие высокие физико-механические свойства. Однако эти материалы не могут быть использованы дл изготовлени деталей узлов трени типа втулок и вкладьшей вследствие низких антифрикционных свойств.Known press materials based on epoxy resins with fiberglass having high physical and mechanical properties. However, these materials cannot be used for the manufacture of parts of friction-type frictional and insert nodes, due to their low anti-friction properties.
Дл придани антифрикционных свойств материалу в процессе изготовлени в него вводитс измельченный фторопласт-4 в количестве 5-30 об.%. In order to impart antifriction properties to the material during the manufacturing process, crushed fluoroplast-4 is introduced into it in an amount of 5-30% by volume.
Практически получение втулок из предлагаемого материала производитс следующими методами:In practice, the production of bushings from the material proposed is carried out by the following methods:
1.Прессованием стеклоткани, пропитанной эпоксидным компаундом, содержащим фторопласт, с последующей термообработкой.1. By pressing glass fiber impregnated with epoxy compound containing fluoroplastic, followed by heat treatment.
2.Намоткой стеклоткани, пропитанной эпоксидным .кампаундом, с одновре2.Melled fiberglass impregnated with epoxy resin with simultaneous
менной подачей фторопласта в течение намотки первых 5-7 слоев.Fluoroplastic feed during the winding of the first 5-7 layers.
3. Нанесение смеси эпоксидной смолы с фторопластом и стекловолокном на внутреннюю поверхность втулки методом центробежного лить .3. Applying a mixture of epoxy resin with fluoroplastic and fiberglass on the inner surface of the sleeve by centrifugal casting.
Пример. В эпоксидное св зующее ввод т 25 об.% фторопласта с размерами частиц 0,5-1,5 мм. Слои стеклоткани пропитывают этим св зующим и подвергают формованию.Example. 25 vol.% Fluoroplastic with a particle size of 0.5-1.5 mm is introduced into the epoxy binder. Fiberglass layers are impregnated with this binder and molded.
Издели из этого материала типа втулок прошли длительные испытани на специальных стендах.при удельном давлении 250 кг/см, скорости 0,004 м/сек. Испытани показали, что материал в этих услови х может работать без смазки, со смазкой .водой или солидолом.Products made from this material of the type of sleeves underwent lengthy tests on special stands. At a specific pressure of 250 kg / cm and a speed of 0.004 m / s. Tests have shown that the material under these conditions can work without lubrication, with water or grease lubrication.
Стендовые испытани , проведенные при кг/см и скорости 0,01 м/сек показали, что материал работал несколько сот часов без существенного износа.Bench tests carried out at kg / cm and speeds of 0.01 m / s showed that the material worked for several hundred hours without significant wear.
