DEVICE FOR ABRASIVE TREATMENT, PROVIDING PLANETARY MOTION AT SMALL CROSS-SIDED DISTANCES Russian patent published in 2018 - IPC B24B31/116 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of abrasive processing and can be used for finishing with a free abrasive of the outer surfaces of composite parts. Device comprises a container with elastic walls, filled with an abrasive medium, an input shaft with a rotation drive and a shaft with a mandrel for mounting the part. In the lid of the container, the support and protective covers are mounted with bearings. Input shaft is rigidly connected to a support cover in which the shaft with a mandrel is installed in the bearings with eccentricity. Mandrel is made with a ring gear, kinematically connected to the ring gear formed on the inner surface of the container lid. Center-to-center distance between the input shaft and the mandrel shaft is selected according to their radii.

EFFECT: as a result, the quality of machining of parts is improved and the overall dimensions of the device are reduced with the increase in the nomenclature of the machined parts.
