Abstract: A chuck has a chuck body at least generally centered on a body axis and a collet in the hole and having an external screwthread. A ring axially nondisplaceable in the body has an internal screwthread engaging the screwthread of the collet and external gear teeth. The body is formed with a radially outwardly open cavity seat in which some of the teeth of the ring are exposed. A gear fitted in the seat meshes with the ring teeth and can rotate about a drive axis not parallel to the body axis to rotate the ring about the body axis. According to the invention a sleeve on the chuck extends axially across and covers the seat to retain the gear therein and is formed with a through going aperture through which a tool can fit to engage and rotate the gear.

Abstract translation: 卡盘具有卡盘主体，该卡盘主体至少大致以身体轴线为中心，并且孔中的夹头具有外部螺纹。 在主体中轴向不可替代的环具有接合夹头和外齿轮齿的螺纹的内螺纹。 主体形成有径向向外敞开的空腔，其中环的一些齿露出。 安装在座椅中的齿轮与环形齿轮啮合并且可以围绕不平行于车身轴线的驱动轴线旋转以围绕车身轴线旋转环。 根据本发明，卡盘上的套筒轴向延伸并覆盖座椅，以将齿轮保持在其中，并且形成有通孔，工具可以通过该通孔来啮合和旋转齿轮。
