Description
Изобретение относитс к машинострое нию, а именно к подшипникам качени Известен сепаратор подшипника качени , состо щий из двух полуобойм, с пазами под тела качени |1. Недостаток известного сепаратора состоит в том, что он не обеспечивает во врем работы нодшипника периодических разворотов шаровых тел качени вокруг произвольных осей и тем самым снижает ресурс и надежность подшипника. Цель изобретени - повышение долговечности подшипника. Указанна цель достигаетс тем, что гнезда выполнены с двум диаметрально противоположными сферическими участками , разделенными промежуточными участками с радиусом кривизны меньше радиуса сферических участков, расположенных асимметрично относительно окружности, проход щей , через центры тел качени , при этом на переходных участках выполнены маслосборные карманы. На фиг. 1 схематически изображен подшипник с сепаратором, разрез; на фиг. 2 - вид А на фиг. 1 (гнездо сепаратора с . телом качени в направлении к оси гюдшипника без наружного кольца); на фиг. 3 - вид Б на фиг. 1 (вид гнезда в направлении от оси подшипника без внутреннего кольца ); на фиг. 4 - разрез В lO-OB на фиг. 2 (взаимное расположение сферических и переходных участков гнезда сепаратора , образующих карманы); на фиг. 5 - разрез BjO-OBj на фиг. 2; на фиг. 6 -вариант под11:кпкика с сепаратором, гнезда которого имеют карманы; на фиг. 7 - вид Г на фиг. 6; на фиг.- 8 - разрез EI-Ej на фиг. 7. Подшипник имеет наружное i и внутреннее 2 кольца, шаровые тела качени 3, сепаратор 4, состо щий из одинаковых половинок 5 и 6, образующих в собранном виде гнезда 7 с карманами 8-11. Половинки 5 и 6 сепаратора скреплены с помощью заклепок 12. Подшипник с сепаратором работает следующим образом. Наружное кольцо укреплено неподвижно в корпусе машины с горизонтально расположенным ротором, а внутреннее кольцо 2 находитс иа шейке вала ротора машины. В этом случаесила веса ротора машины передаетс с внутреннего кольца 2 через тела качени 3. расположенные в нижней нагруженной части подшипннка, на наружное кольцо 1 подшнпннка. Привращеннн ротора машины сила веса ротора распредел етс между телами качени 3, расположен|1ыми в каждый рассматрнваемый момент времени в нижней нагруженной части подшипника. Тела качени 3, расположенные в нижней части подшипника . Тела качени 3, расположенные в нижней части подшипника, вращаютс только вокруг осей, параллельных оси подшнпника . Тела качени 3, наход щиес в рассматриваемый момент времени в верхней ненагружениой части подшигшнка, не нагружены силой весе ротора машины. В этом случае при наличии названных карманов 8-П на шаровые тела качени 3 действуют разворачивающие моменты.The invention relates to mechanical engineering, namely, to rolling bearings. A rolling bearing separator is known, consisting of two half-voids, with grooves under the rolling elements | 1. A disadvantage of the known separator is that it does not provide, during operation of the bearing, the periodic turns of the ball rolling bodies around arbitrary axes and thereby reduces the life and reliability of the bearing. The purpose of the invention is to increase the durability of the bearing. This goal is achieved by the fact that the nests are made with two diametrically opposed spherical sections separated by intermediate sections with a radius of curvature less than the radius of spherical sections located asymmetrically with respect to the circumference passing through the centers of the rolling bodies, while the transition pockets are made. FIG. 1 shows schematically a bearing with a cage, a section; in fig. 2 is a view A of FIG. 1 (separator seat with a rolling body in the direction of the bearing bearing without an outer ring); in fig. 3 is a view B in FIG. 1 (view of the socket in the direction from the bearing axis without the inner ring); in fig. 4 shows a section B lO-OB in FIG. 2 (the mutual arrangement of the spherical and transitional sections of the separator nest, forming pockets); in fig. 5 shows a section BjO-OBj in FIG. 2; in fig. 6 is an option under 11: a cap with a separator, the nests of which have pockets; in fig. 7 is a view of FIG. 6; FIG. 8 is a section through EI-Ej of FIG. 7. The bearing has an outer i and inner 2 rings, rolling ball spherical bodies 3, a separator 4 consisting of identical halves 5 and 6, forming assembled sockets 7 with pockets 8-11. The halves 5 and 6 of the separator are fastened using rivets 12. The bearing with the separator works as follows. The outer ring is fixed in a fixed frame of the machine with a horizontal rotor, and the inner ring 2 is located on the neck of the rotor shaft of the machine. In this case, the weight of the rotor of the machine is transferred from the inner ring 2 through the rolling elements 3. located in the lower loaded part of the bearing, to the outer ring 1 of the sub-link. Adjusted by the rotor of the machine, the weight of the rotor is distributed between the rolling bodies 3, located at the first moment of time in the lower loaded part of the bearing. Body rolling 3, located at the bottom of the bearing. The rolling bodies 3 located in the lower part of the bearing rotate only around axes parallel to the axes of the bearing. The rolling bodies 3, which are at the considered time in the upper non-loading part of the upper arm, are not loaded by the force of the weight of the rotor of the machine. In this case, in the presence of these 8-P pockets, the unwinding moments act on the ball body of rolling 3.
