Abstract

FIELD: mechanical engineering. SUBSTANCE: journal of the shaft is received in the housing. The journal receives a linear magnet perpendicular to the longitudinal axis of the shaft. Between the journal of the shaft and housing is porous ring insert made of ferromagnet material. The pores are filled with lubricant. When the shaft rotates the magnetization of the insert is reversed. As a result, its linear sizes change and lubricant is pressed out from the pores. EFFECT: enhanced durability. 1 dwg

Description

Изобретение относится к машиностроению, а точнее к опоре валов, а именно к подшипниковым узлам скольжения. Цель изобретения увеличение долговечности путем повышения интенсивности подачи смазки. The invention relates to mechanical engineering, and more specifically to the support of the shafts, and in particular to sliding bearing units. The purpose of the invention is to increase durability by increasing the rate of lubricant supply.

Цель достигается тем, что вкладыш выполнен из ферромагнитного материала, а магнит выполнен линейным и размещен в цапфе вала перпендикулярно продольной оси вала. The goal is achieved by the fact that the liner is made of ferromagnetic material, and the magnet is linear and placed in the shaft journal perpendicular to the longitudinal axis of the shaft.

На чертеже представлен общий вид устройства. The drawing shows a General view of the device.

Подшипниковый узел скольжения содержит цапфу вала 1, которую охватывает корпус 2 подшипника скольжения с размещенным в его радиальных пазах пористым вкладышем 3, выполненным из ферромагнитного материала, поры которого заполнены смазкой 4. В цапфе вала 1 расположен постоянный линейный магнит 5, ось которого перпендикулярна продольной оси вала 1. Внешняя неподвижная часть корпуса подшипника элемент 6. The sliding bearing assembly comprises a shaft pin 1, which is covered by a sliding bearing housing 2 with a porous liner 3 placed in its radial grooves and made of ferromagnetic material, the pores of which are filled with lubricant 4. A shaft linear magnet 5 has a permanent magnet 5 whose axis is perpendicular to the longitudinal axis shaft 1. The outer fixed part of the bearing housing element 6.

Вкладыш 3 может быть выполнен, например, спеканием ферромагнитного порошка. The liner 3 can be performed, for example, by sintering a ferromagnetic powder.

Подшипниковый угол скольжения работает следующим образом. Bearing sliding angle works as follows.

Ферромагнитный вкладыш 3 намагничивается в поле постоянного магнита 5. Вращение вала 1 приводит к изменению магнитного поля. Происходит периодическое перемагничивание вкладыша 3, в результате которого линейные размеры вкладыша 3 изменяются с частотой вращения вала 1. Изменение линейных размеров вкладыша 3 сопровождается выдавливанием жидкой смазки 4 из пор материала вкладыша 3. При этом интенсивность выделения смазки увеличивается с увеличением частоты вращения вала 1. The ferromagnetic liner 3 is magnetized in the field of the permanent magnet 5. The rotation of the shaft 1 leads to a change in the magnetic field. A periodic magnetization reversal of the liner 3 occurs, as a result of which the linear dimensions of the liner 3 change with the rotational speed of the shaft 1. Changing the linear dimensions of the liner 3 is accompanied by extrusion of liquid lubricant 4 from the pores of the material of the liner 3. In this case, the rate of release of lubricant increases with increasing frequency of rotation of the shaft 1.
