Description
(54) АНТИФРИКЦИОННЫЙ СПЛАВ ДЛЯ(54) ANTIFRICTION ALLOY FOR
ПОДШИПНИКОВ СКОЛЬЖЕНИЯBEARING SLIDES
1one
Изобретение относитс к машиностроению, в частности к подшипникам скольжени .The invention relates to mechanical engineering, in particular to sliding bearings.
Известны антифрикционные сплавы дл подшипников скольжепи на основе ситалла, содержаш,ие в качестве металлической добавки медь.Known antifriction alloys for sliding bearings based on glass, containing copper as a metallic additive.
Однако при работе в вакууме и на воздухе при повышенных скорост х скольжени долговечность этого сплава уменьшаетс .However, when operating in vacuum and in air at elevated slip rates, the durability of this alloy is reduced.
Цель изобретени - увеличение долговечности в услови х трени на воздухе и в вакууме без смазки.The purpose of the invention is to increase durability under the conditions of friction in air and in vacuum without lubrication.
Эта цель достигаетс тем, что описываемый сплав содержит в качестве металлической добавки олов ппую бронзу при следуюш.ем соотношении компонентов (в вес. %): ситалл 60-90, олов нна бронза 10-40.This goal is achieved by the fact that the described alloy contains pn bronze as a metal additive for tin, with the following ratio of components (in wt.%): Sitall 60-90, tin bronze 10-40.
При этом олов нна бронза содержит (в вес. %): 90-92 .меди и 10-8 олова.In this case, tin bronze contains (in wt.%): 90-92. Media and 10-8 tin.
Описываемый сплав можно получить методом порошковой металлургии по следуюшей техпологической схеме.The described alloy can be obtained by powder metallurgy method according to the following technological scheme.
Исходный материал ситалл измельчают, в хнаровой мельнице до величины зерна менееThe raw material of the sitall is crushed, in a granule mill to a grain size less than
60 мк. Порошок ситалла смешивают с порошком олов нной бронзы в соотношении, указанном выше, до получени однородной смеси и подвергают гор чему прессованию при 900° С в течение 2 час, после чего производ т известным способом термообработку по ступенчатому тепловому режиму.60 microns The sitall powder is mixed with tin bronze powder in the ratio indicated above until a homogeneous mixture is obtained and is hot pressed at 900 ° C for 2 hours, after which the heat treatment is carried out in a known manner using a stepwise thermal regime.
