Description

Подшипники с газовой смаэкой, выполненные в виде неразрезной втулки, известны. Однако при нагревании таких подшипников во врем  работы возможны закликивани  вала в них. В результате заклинивани  повреждаютс  рабочие поиер кости вала и юдшииника.Bearings with gas smear, made in the form of a continuous sleeve, are known. However, when such bearings are heated during operation, the shaft may call into them. As a result of seizure, workers damage the bones of the shaft and the shaft shaft.

Описываемый подшипник предотЕраш,ает возможность заклипии ь ни . Это достигаетс  тем, что подш1ипник имеет на наружной поверхности проточку, создающую замкнутый кольцевой зазор между подшипником и корпусом и обеспечивающую его сопр жение с корпусом по двум кольцевым по скам. Переход от пз сков к рабочей части подшипни:ка выполнен в виде колеи 1наименьшей возможной толщины, обеспечивающей достаточную жесткость подшипника. Кроме того, в подшипнике применен антифрикционный вкладыш, установленный с таким нат гом, который, уменьша сь ino мере повышени  температуры, не исчезает |При ее наибольшем значении, а материал Подшипника выбран так, чтобы коэффициент расширени  вала был промежуточным меж.а.у коэффициентами расширени  вкладыша и подшипника.The described bearing prevents the possibility of sticking. This is achieved by the fact that the bearing has a groove on the outer surface that creates a closed annular gap between the bearing and the housing and ensures its mating with the housing along two annular ribs. The transition from pz skov to the working part of the bearing: ka is made in the form of a track 1 of the smallest possible thickness, providing sufficient rigidity of the bearing. In addition, an anti-friction liner is used in the bearing, which is installed with such a tension that, while decreasing as temperature increases, does not disappear. | At its highest value, the Bearing material is chosen so that the shaft expansion coefficient is an intermediate interval. liner and bearing expansion.

На чертеже изображен описываемый подшипник в продольном разрезе .The drawing shows the described bearing in longitudinal section.

В конической обойме / запрссссван пкладьш 2. Величина нат га вкла1г1.ыша регулируетс  и фиксируетс  гайкой 3.In the conical cage / pad, the insert 2 is inserted. The magnitude of the pull-in tension of the mouse is adjusted and fixed by the nut 3.

Подшипник сопр гаетс  с корпусом 4 (например, щитом электрошпи дел ) 1при помощи двух кольцевых конической формы по сков 5 и закрепл етс  гайкой 6.The bearing is mated to the housing 4 (for example, by the electrospee shield) 1 by means of two annular conical shapes 5 and fixed by the nut 6.

Наличие проточки 7 на нрпужной поверхности обоймы при нагреве обеспечивает подшипнику возможность свободного расширени . ТемnepaWpa его при этом практически совпадает с темпер.этурой вала, так как kiacca подшипника мала и теплоотвод в корпус затруднен, воздушной прослойкой, образованной проточкой 7, а та«же проточками 8. Кро:1)е того, подбором материала вкладыша и обоймы, а также толщиThe presence of the groove 7 on the outer surface of the sleeve when heated provides the bearing with the possibility of free expansion. ThenepaWpa of it at the same time practically coincides with the temperature of the shaft, since the kiacca of the bearing is small and the heat sink into the housing is difficult, the air gap formed by the groove 7, and the same by the grooves 8.
