用于通过收缩夹紧工具的夹紧卡盘具有设置有用于容纳用工具轴夹紧的工具的插座的卡盘体，并且具有用于可插入工具的端侧邻接表面，使得在插入期间的后侧肩部 工具轴向地抵靠邻接表面和环形元件并且在轴向方向上可轴向支撑在卡盘主体上并且设置有邻接表面，环形元件的邻接表面位于轴向邻接卡盘的邻接表面的端部的前方 本体与工具的肩部相关联，用于通过环形元件相对于卡盘主体轴向夹紧插入的工具。

There is a chuck (10) for clamping tools (11) proposed by shrink fit, having a chuck body (12) of a length (13) with a towards one end open housing (14) for inserting and receiving the to exciting tool (11) with its shaft (17). The chuck body (12) has at the end of the recording (14) a terminal-end contact surface (15), to which the tool (11) with a rear shoulder (19) can abut axially. In the region of the contact surface (15) supporting the end portion (20) of the chuck body (12) is a configured as a shrink ring ring element (21) is arranged, which is axially braced by means of truncated conical surface (25) on a truncated conical surface (24) of the end portion (20) and a front shoulder of the tool (19) associated with the stop surface (23) for axially clamping of an inserted tool (11) (Fig. 2).
