Description

II

Изобретение относитс  к машине-строению и может быть использовано в быстроходных машинах, например в турбокомпрессорах.The invention relates to a machine-structure and can be used in high-speed machines, for example in turbo-compressors.

По основному авт. св. № 270405 известен подшипник ско гьжени , содержащий корпус, плавающую втулку и упорную втулку, котора  .входит торцом в радиальное отверстие плавающей втулки и служит дл  предохранени  последней от проворачивани  и осевого перемещени  } .According to the main author. St. No. 270405 is known for a spin bearing comprising a housing, a floating sleeve and a stop sleeve, which terminates in the radial opening of the floating sleeve and serves to protect the latter from turning and axial movement}.

Недостатком известного подшипника скольжени   вл етс  сравнительно быстрый износ поверхностей плавающей и упорной втулок в местах их контакта . Это объ сн етс  тем, что при наличии определенной величины об зательного зазора в посадке упорной втулки в отверстии плавающей втулки в процессе работы подшипника возникают вращательные колебани  плавающей втулки, следствием которых  вл ютс  значительные пульсирующие напр жени .A disadvantage of the known sliding bearing is the relatively rapid wear of the surfaces of the floating and thrust sleeves at their contact points. This is due to the fact that, if there is a certain amount of the required clearance in the fit of the thrust bushing in the opening of the floating bushing, rotational oscillations of the floating bushing occur during the operation of the bearing, resulting in significant pulsating voltages.

Привод щие к износу контактирующих поверхностей.Wearing contact surfaces.

Цель изобретени  - повышение долговечности подшипника путем демпфировани  вращательных колебаний плавающей втулки.The purpose of the invention is to increase the durability of the bearing by damping the rotational vibrations of the floating sleeve.

Поставленна  цель достигаетс  тем, что в подшипнике скольжени , содержащем корпус, плавающую втулку и упорную втулку, котора  входит торцом в The goal is achieved by the fact that in a sliding bearing comprising a housing, a floating bushing and a thrust bushing, which ends in

10 радиальное отверстие плавающей втулки, упорна  ртулка выполнена упругой.10 radial opening of the floating sleeve, the resistant sleeve is made elastic.

На чертеже схематически изображен подшипник скольжени .The figure shows the sliding bearing schematically.
