Description
Известны подшипники скольжени , вкладыши которых выполнены из прессованной пластифицированной древесины, но такие подшипники недостаточно износоустойчивы.Known bearings, liners which are made of molded plasticized wood, but such bearings are not durable.
С целью повышени износоустойчивости подшипников из прессованной древесины и снижени коэффициента трени в прессованную древесину ввод т закись меди, глицерин и стеарат кальци .In order to increase the durability of bearings made of pressed wood and reduce the coefficient of friction, copper oxide, glycerin and calcium stearate are introduced into the pressed wood.
Дл этого заготовки древесины в виде кубиков , например, из березы, влажностью до 7-9% пропитывают под действием избыточного давлени закисью меди в стадии образовани кристаллов, глицерином и поверхностно-активным вешеством, например, стеаратом кальци . Состав пропиточного материала принимают из расчета 50% по весу глицерина, 49% закиси меди и 1 % стеарата кальци . Пропитанна древесина содержит 25-30% по весу пропиточного материала и 70-75% собственно древесины .For this, wood prefabs in the form of cubes, for example, from birch, with moisture up to 7-9%, are impregnated under the action of overpressure with copper oxide in the crystal formation stage, glycerin and surface active substance, for example, calcium stearate. The composition of the impregnating material is based on 50% by weight of glycerol, 49% cuprous oxide and 1% calcium stearate. Impregnated wood contains 25-30% by weight of the impregnating material and 70-75% of the actual wood.
Предлагаемый материал значительно повышает износоустойчивость пар трени и снижает 5 его коэффициент.The proposed material significantly increases the wear resistance of friction pairs and reduces its coefficient 5.
