TURBOCHARGER OF THE PRESSURIZATION SYSTEM OF THE INTERNAL COMBUSTION ENGINE Russian patent published in 2022 - IPC F01D25/16 

FIELD: turbochargers.

SUBSTANCE: invention relates to turbochargers for pressurization systems of internal combustion engines. The task is achieved by the fact that the turbocharger contains a housing, a turbine wheel, as well as a compressor wheel connected to it by means of a shaft, and a shaft bearing assembly made in the form of rolling bearings located in the housing. According to the invention, the rolling bearings are made in the form of at least one group, consisting of at least three support blocks located around the shaft in a plane perpendicular to the plane of rotation of the shaft, and made in the form of rollers rolling with their outer contact surface of the rolling around the geometric axis of rotation of the shaft along the inner support surface in the housing and in contact with the specified rolling surface with the outer support surface located around the shaft. At the same time, the rollers are equipped with a means to prevent their slipping relative to the supporting surfaces in contact with them, which is made in the form of a planetary gearing, and the bearing assembly is equipped with a device that limits the axial movement of the shaft with wheels relative to the housing and is made in the form of thrust surfaces, which are located with the possibility of interacting with persistent surface of the rollers.

EFFECT: increase in efficiency, reliability and resource.
