    • The invention relates to a shank chisel (10) with a chisel head (12) and a chisel shank (16), wherein the chisel shank (16) has a securing element retainer (181) in which a securing element (40) is arranged. In order to enable a simple installation of the shank chisel (10) in a chisel holder (30) in a safe and maintenance-optimized operating mode, according to the invention, a tensioning element (20) can be displaced relative to the chisel shank (16) in such a way that at least one part of the outer contour of the securing element (40) is changed. The invention further relates to a corresponding fixing assembly (1) for a shank chisel (10) in a chisel holder (30).
    • 本发明涉及一种具有凿头(12)和一凿杆(16)的柄部凿(10),所述钻铤(16)具有在其中的熔丝元件(40)被布置在固定构件接收器(181)。 为了使在操作的可靠和维修优化模式中的刀具保持器(30)的轴的工具(10)的安装方便,它是按照本发明所提供的是一个夹紧元件(20)相对相对于所述凿杆(16)是可调节的,使得至少一部分 固定元件(40)的外轮廓被改变。 本发明还包括用于在刀座(30)的柄部凿(10)相应的附接装置(1)。

    • The invention relates to a shank tool for a road milling machine or the like, having a tool head (12) and a tool shank (11), wherein the tool shank (11) has a first cylindrical section (11.1) which indirectly or directly adjoins the tool head (12), and wherein the tool shank (11) has a second cylindrical section (11.3) which is remote from the tool head (12) and indirectly or directly adjoins the first cylindrical section (11.1), and wherein the diameter (c) of the second cylindrical section (11.3) differs from the diameter (b) of the first cylindrical section (11.1). With such a shank tool, improved use properties arise in that the first cylindrical section (11.1) has a diameter (b) in the range between 18 mm and 30 mm and an extent (B) in the direction of the centre longitudinal axis of the tool shank of less than 30 mm.
    • 本发明涉及一种杆刀具用于道路铣床或用凿子头(2)和一凿杆(11)等,所述钻铤(11)具有一第一圆柱形部分(11.1),其直接或间接地连接在凿头(12), 并且其中,所述凿刀柄(11)具有凿头的背向直接或间接地与第一圆筒部(11.1)连接的第二圆柱部(11.3)(12),并且其中,所述第二圆柱形部分的直径(C)(11.3) 从第一筒状部(11.1)的直径(b)偏离。 在导致第一圆柱形部分(11.1)这种studcutter改进的性能特征具有18毫米和30毫米,一延伸部(B)之间的范围内的直径(b)是在钻铤大于30mm的中心纵向轴线的方向上变小。

    • The invention relates to a tool holder for a road milling machine or similar, comprising a base part (40), on which a tool shank (42) and a collar (41) are formed, the collar (41) having a tool receiving opening and said opening being formed from a bush-type insert (20) consisting of a hard material. In a tool holder of this type, in order to promote good rotational behaviour of the tool and guarantee support for the latter without the need for numerous parts, the tool receiving opening is designed as a stepped bore that has a first and a second diameter region (21, 23), the first diameter region having a greater inner diameter than the second diameter region.
