    • The invention relates to a finger element, comprising a carrier component (1), a first finger member (5) having a first articulated connection (2) to the carrier component, a second finger member (6) having a second articulated connection (7) to the first finger member, an actuator for the first articulated connection (2) with a motor having a drive shaft, and a worm gear having a threaded worm, and a toothed segment engaging on the threaded worm, and further comprising a coupling mechanism (8) between the first and second articulated connections. The object of the invention is to modify a finger element such that the finger element in the active and passive functions thereof and in the dimensions thereof comes very close to a natural finger. The object is achieved in that the threaded worm is positively mounted axially movably on the drive shaft and axially guided through separate guides.
    • 本发明涉及一种手指元件,包括载体部件(1),具有到载体部件的第一铰接连接件(2)的第一指状件(5),具有第二铰接连接件(7)的第二指状件(6) )到第一指状构件,用于具有驱动轴的电动机的第一铰接式连接件(2)的致动器,以及具有螺纹蜗杆的蜗轮和与螺纹蜗杆接合的齿形部分,还包括联接机构 (8)在第一和第二铰接连接之间。 本发明的目的是修改手指元件,使得其主动和被动功能中的手指元件及其尺寸非常接近自然的手指。 实现目的在于,螺纹蜗杆可轴向地可移动地安装在驱动轴上并且轴向地被引导通过单独的引导件。
