Description

Изобретение относитс  к машиностроению , а именно к подшипникам качени .The invention relates to mechanical engineering, namely rolling bearings.

Известен подшипник качени , содержащий наружное и внутреннее кольца, тела качени  между ними, разделенные отдельными сепарирующими элементами р.A roller bearing is known, containing outer and inner rings, rolling bodies between them, separated by separate separating elements p.

В процессе работы указанного подшипника между телами качени  и сепарирующими элементами возникает трение скольжени , что снижает долговечность подшипника из-за износа трущихс  поверхностей. При этом также возникают потери на трение, снижающие КПД подшипника. Эти недостатки усиливаютс  и тем, что сепаратор закрывает значительную часть тел качени , ухудша , тем самым, услови  подвода смазки.During operation of the specified bearing, sliding friction occurs between the rolling elements and the separating elements, which reduces the durability of the bearing due to wear of the rubbing surfaces. This also results in friction losses, which reduce the efficiency of the bearing. These disadvantages are aggravated by the fact that the separator covers a significant part of the rolling elements, thus worsening the conditions for supplying lubricant.

Цель изобретени  - повысить долговечность подшипника путем снижени  потерь на трение.The purpose of the invention is to increase the durability of the bearing by reducing friction losses.

Указанна  цель достигаетс  тем, что в подшипнике качени , содержащем внутреннее и наружное кольца, тела качени  между ними, разделенные отдельными сепарирующими элементами, каждый сепарирующий элемент выпол- нен в виде двух роликов, установленных с зазором друг относител но друга на параллельно расположенных ос х вращени , которые жестко соеди10 нены между собой, при этом суммарный диаметр двух роликов меньше диаметра тела качени .This goal is achieved by the fact that in a rolling bearing containing an inner and outer ring, rolling bodies between them, separated by separate separating elements, each separating element is made in the form of two rollers mounted with a clearance relative to each other on parallel axes of rotation. which are rigidly connected to each other, while the total diameter of the two rollers is less than the diameter of the rolling body.

На фиг. 1 изображен подшипник, обший вид; на фиг. 2 - сечение сепа15 рирующего элемента.FIG. 1 shows a bearing, general view; in fig. 2 - section of separating element.

В подшипнике качени  между внутренней 1 и наружной 2 дорожками качени  размещены тела качени  3, раздаленные отдельными сепарирую20 щими элементами 4.In the rolling bearing between the inner 1 and outer 2 raceways, the rolling bodies 3 are spaced apart by separate separating elements 4.

Сепарирующие элементы 4 выполнены в виде двух роликов 5 и 6, уст;. новленных с зазором друг относительThe separating elements 4 are made in the form of two rollers 5 and 6, mouth ;. innovated with a gap friend relative
