Inventia se refera la un lagar pentru arborele principal al unei masini-unelte, ca de exemplu al unei masini de rectificat cu arbore vertical sau al unui strung carusel. La lagarul, conform inventiei, rulmentul radial cu doua rânduri de role are un inel interior cu un alezaj conic care permite reglajul jocului radial prin folosirea unor inele de ajustare, ghidarea axiala a platoului lagaruit asigurându-se printr-un rulment axial cu bile montat pretensionat prin intermediul unor arcuri.The invention relates to a bearing for the main shaft of a machine tool, such as a vertical shaft grinding machine or a carousel lathe. At the bearing according to the invention, the radial roller bearing with two rows of rollers has an inner ring with a conical bore which allows the regulation of the radial play by using adjusting rings, the axial guidance of the lagged plate being ensured by an axial ball bearing with prestressed balls through springs.
BEARING BEARING WITH TWO ROWS OF BEARING ELEMENTS PROVIDED WITH A BEARING RETAINING PIECE, A RETAINING PART THAT CAN BE USED FOR THIS PURPOSE, AND ASSEMBLY PROCEDURE OF SUCH BEARING.
