Abstract

Изобретение относитс  к машиностроению и может быть использовано в машинах и оборудовании, работающих в услови х сильной запыленности и загр зненности. Цель изобретени  - повышение долговечности путем исключени  контакта внутренней полости подшипника с окружающей средой. Повышение долговечности достигаетс  тем, что уплотнительный элемент выполнен непосредственно на сепараторе, с внутренн   полость подшипника и контактирующие поверхности изолированы от действи  окружающей среды с помощью шайб, закрепленных одной стороной в колоде, а друга  сторона отогнута внутрь полости подшипника. 1 ил.The invention relates to mechanical engineering and can be used in machines and equipment operating in conditions of high dust and contamination. The purpose of the invention is to increase durability by eliminating the contact of the inner cavity of the bearing with the environment. Increased durability is achieved by the fact that the sealing element is made directly on the separator, with the internal cavity of the bearing and the contacting surfaces are insulated from the environment with the help of washers fixed by one side in the deck, and the other side is bent inside the bearing cavity. 1 il.

Description

Изобретение относитс  к машиностроению и может быть использовано в оборудовании , работающем в услови х сильной запыленности и загр зненности.The invention relates to mechanical engineering and can be used in equipment operating under conditions of high dust and contamination.

Цель изобретени  - повышение долговечности путем исключени  воздействи  окружающей среды на внутреннюю полость подшипника.The purpose of the invention is to increase durability by eliminating the effect of the environment on the internal cavity of the bearing.

На чертеже показан подшипник качени , разрез.The drawing shows the rolling bearing section.

Подшипник качени  содержит кольца 1 и 2, размещенный между ними сепаратор 3 с телами 4 качени  и уплотнительный элемент 5, выполненный в теле сепаратора 3 и контактирующий с шайбами и кольцом 2 посредством выступов 7 и 8 соответственно. При этом уплотнительный элемент 5 закрыт от окружающей среды шайбами 6, а места контакта выступов 7 и 8 уплотнений 5 с шайбами 6 и кольцом 2 располагаютс  во внутренней полости, заполненной смазкой. Свободный конец 9 шайбы 6 отогнут во внутреннюю полость подшипника качени .The rolling bearing comprises rings 1 and 2, a separator 3 disposed between them with rolling bodies 4 and a sealing element 5 made in the body of the separator 3 and contacting the washers and the ring 2 by means of projections 7 and 8, respectively. In this case, the sealing element 5 is closed from the environment by the washers 6, and the places of contact of the projections 7 and 8 of the seals 5 with the washers 6 and the ring 2 are located in the internal cavity filled with lubricant. The free end 9 of the washer 6 is bent into the internal cavity of the rolling bearing.

Пошипник качени  работает следующим образом.The rolling bearing works as follows.

При вращении кольца 2 заложенна  в подшипник качени  смазка разжижаетс  под действием механических сил и увеличени  температуры, св занного с наличием трени  качени  и трени  скольжени  между детал ми. Смазка посто нно разбрызгиваетс  вращающимис  детал ми и циркулирует по всему объему внутренней полости подшипника качени , ограниченному кольцевыми площадками контакта выступов 7 и 8 уплотнительного элемента с шайбами 6 и кольцом 2 соответственно. Циркулирующа  во внутренней полости подшипника качени  смазка, кроме своего пр мого назначени  - обеспечени  смазывани  мест контакта тел качени  с кольцами , смазывает также кольцевые площадки контакта выступов 7 и 8, уплотнительный элемент 5 с шайбами 6 и кольцом 2. При этом шайба 6, свободный конец 9 которой отогнут-во внутреннюю полость подшипника качени , предохран ет кольцевые площадки контакта от непосредственного воздействи  окружающей подшипник качени  среды.As the ring 2 rotates, the lubricant embedded in the rolling bearing liquefies under the action of mechanical forces and an increase in temperature due to the presence of rolling friction and sliding friction between parts. The lubricant is constantly sprayed by rotating parts and circulates throughout the entire volume of the rolling bearing inner cavity bounded by the annular contact areas of the protrusions 7 and 8 of the sealing element with the washers 6 and the ring 2, respectively. The lubricant circulating in the internal cavity of the rolling bearing, besides its intended purpose - to lubricate the contact points of the rolling bodies with the rings, also lubricates the annular contact points of the projections 7 and 8, the sealing element 5 with the washers 6 and the ring 2. At the same time, the washer 6, the free end 9, which is bent into the internal cavity of the rolling bearing, protects the annular contact pads from direct exposure to the surrounding rolling bearing medium.

fefe

Предлагаема  конструкци  позвол ет повысить износоустойчивость и защитить внутреннюю полость подшипника от воздействи  окружающей среды.The proposed design allows to increase the wear resistance and protect the internal cavity of the bearing from the effects of the environment.
