Abstract
Изобретение относитс к машиностроению, в частности к подшипникам качени , примен емым преимущественно в т желонагруженных небыстроходных узлах машин. Цель изобретени - повышение грузоподъемности сферических роликовых подшипников. Размеры деталей подшипников выбираютс с возможностью обеспечени полного заполнени роликами окружности их центроиды, в частности, количество роликов в р ду определ етс математической зависимостью. При работе подшипника ролики, обкатыва сь по поверхност м наружного и внутреннего колец, по одну сторону от среднего сечени роликов контактируют и взаимодействуют с перемычками сепаратора, а по другую сторону от среднего сечени контактируют и взаимодействуют непосредственно между собой. 4 ил.The invention relates to mechanical engineering, in particular, to rolling bearings, which are used mainly in tons of yellow loaded non-speed machine components. The purpose of the invention is to increase the carrying capacity of spherical roller bearings. The dimensions of the bearing parts are chosen to ensure that the centroids completely fill the rollers of the circumference, in particular, the number of rollers in a row is determined by a mathematical relationship. During the operation of the bearing, the rollers, rolling on the surfaces of the outer and inner rings, on one side of the middle section of the rollers, contact and interact with the separator bridges, and on the other side of the middle section, contact and interact directly with each other. 4 il.
Description
Изобретение относитс к машиностроению , а именно к подшипникам качени .The invention relates to mechanical engineering, namely rolling bearings.
Цель изобретени - повышение грузоподъемности подшипника.The purpose of the invention is to increase the bearing capacity.
На фиг.1 представлен подшипник, осевой разрез; на фиг.2 - развертка конусной поверхности, ось которой ссовпадает с осью подшипника, а образующей вл етс ось вращени ролика; на фиг.3 - сечение А-А на фиг. 2; на фиг.4 - сечение Б-Б на фиг.2.Figure 1 shows the bearing, axial section; Fig. 2 shows a development of a tapered surface, the axis of which coincides with the axis of the bearing, and the forming axis is the axis of rotation of the roller; figure 3 - section aa in fig. 2; figure 4 - section bb in figure 2.

R - радиус образующей ролика; D - наибольший диаметр ролика; - диаметральный зазор между роликом и гнездом сепаратора , позвол ет увеличить количество роликов, что, . в свою oчepeдь приводит к повЕлпению грузоподъем ности подшипника.R is the radius of the forming roller; D is the largest diameter of the roller; - the diametrical gap between the roller and the separator socket allows an increase in the number of rollers, that,. In its turn, leads to bearing capacity of the bearing.
