A drive of a drill chuck having a torque coupling which can be placed on a drive shaft of a motor via a base element on a side opposite of chuck jaws. A torque coupling having meshing ball bearing collars is inserted between the base element and the chuck jaws. A spring-loaded driven end of the torque coupling is connected with the base element and a take-off end of the torque coupling is connected with a jaw housing which guides the chuck jaws, each being fixed against relative rotation. A ring abutment for the spring-loaded driven end is fixed on the base element. A cylindrical sleeve projects from the ring abutment in a direction toward the chuck jaws, which are rotationally movable. The cylindrical sleeve overlaps a fitted cylindrical pipe which is positioned on the jaw housing and encloses the torque coupling. |
