DEVICE FOR GRINDING THRUST CENTER TYPE BODIES OF ROTATION Russian patent published in 2021 - IPC B24B5/14 

FIELD: material processing.

SUBSTANCE: invention relates to the processing of materials by cutting and can be used to restore the surface of thrust centers, in particular roller grinding machines. The device contains a base and a housing mounted on it, an electrospindle placed inside the housing, and a grinding wheel mounted on the output end of the electrospindle. Inside the housing there is a screw connected to the shank of the electric spindle, and a worm gear that is engaged with it, fixed on the first shaft. The second shaft is located parallel to the axis of the electric spindle and is rigidly connected to the base. The housing is made with the possibility of rotation relative to the second shaft, on which a gear wheel with screw teeth is fixed. A mobile gear unit is installed on the first shaft with the possibility of alternating coupling with a wheel mounted on the second shaft.

EFFECT: design features of the device provide the possibility of a rational choice of the circumferential feed during operation, improving the accuracy and quality of the treated surface.
