Description
РЬобретение относитс к антифрикционньпг материалам, в частности, оно касаетс композиций дл изготовлени антифрикционных материалов на основе политетрафторэтилена, имеющих низкий коэффициент трени в уелоВИЯХ сухого трени .The invention relates to antifriction materials, in particular, it relates to compositions for the manufacture of antifriction materials based on polytetrafluoroethylene, which have a low coefficient of friction in dry friction.
Известна комлозици дл изготоилени антифрикциОНных материалов, содержаща нолитетрафторэтилен и наполнитель, в качестве которого и:апользовали порошки молибдена , 1вольфрама и др.The known composition for the manufacture of antifriction materials, containing tetrafluoroethylene and a filler, as well as: powders of molybdenum, 1 tungsten, etc.
Было обнаружено, что антифрикционные материалы на основе политетрафторэтилена MorvT быть получены с очень низким значением коэффициента трени , если в качестве наполнител использовать порошок кобальта в кол честве 10-20 об. о/о от веса политетрафторэтилена .It was found that MorvT polytetrafluoroethylene antifriction materials can be obtained with a very low value of the coefficient of friction, if cobalt powder in a quantity of 10–20 vol% is used as a filler. o / o from the weight of polytetrafluoroethylene.
Издели из предлагаемой колгпозиции могут быть изготовлены обычным опособо.м путем прессовани поропжа политетрафторэтилена с ГОПОШ|КОМ кобальта с последующим спека:исм спрессованного издели при температуре спекани политетрафторэтилена. частиц наполнител составл ют 300 мен/. (около 71 мк).Products from the proposed composition can be made by ordinary methods by pressing polypropylene fluoroethylene with GOPOSH / KOM cobalt followed by specs: is compacted product at polytetrafluoroethylene sintering temperature. filler particles are 300 mens /. (about 71 microns).
В компози.цию можно также вводить обычные твердые смазки, например графит, дисульфид : 1олибдена, нитрид бора.Conventional solid lubricants can also be added to the composition. For example, graphite, disulfide: lolybdenum, boron nitride.
Результаты сравнительных испытаний, приведенпые IB таблице, указывают на преимущество композиций с порощком кобальта в услови х с хого трени по схеме вал - плоский образец с лункой. Во всех случа х использовали образцы, ширина -которых равна ширине вытираемой втулки и составл ет 15 мм. Диаметр 1вала 30 мм, материал вала сталь У8Л; твердость по Роквеллу 60-62; скорость скольжен1 0.5 м/сек: удельна нагрузка 50 кг/см. 3 Предмет изобрете«и Композици дл изготовлеии а-нтифриюционных изделий, содержаща политетрафторэтилен и 10-20 Об. о/о Металличеокого нораш- 5 4 кообразного напол,иите.л , отличающа с тем, что, с целью снижени коэффициента трени и ловышени изиосостойкости в услови х сухого трени , в качестве наполнител июпользоиан порошок кобальта.The results of the comparative tests, given in the IB table, indicate the advantage of compositions with a cobalt powder in conditions of good training according to the scheme: a shaft — a flat sample with a well. In all cases, samples were used, the width of which is equal to the width of the wiped sleeve and is 15 mm. Diameter 1 shaft 30 mm, shaft material steel U8L; Rockwell hardness 60-62; Sliding speed 1 0.5 m / s: specific load 50 kg / cm. 3 The subject matter of the invention and the Composition for the manufacture of non-freeze products containing polytetrafluoroethylene and 10-20 Vol. Metallic Noresh 5 4 coaxial napolite, and the use of a metal, characterized in that, in order to reduce the coefficient of friction and cathodic resistance, under dry friction conditions, cobalt powder is used as a filler.
