Abstract
A twisted string transmission for converting a rotational motion to a linear motion is provided, comprising a motor (1) and a string (2) to be connectable to a load (3). The string (2) has a variable diameter along its length.
Claims13
A twisted string actuator for converting a rotational motion to a linear motion, comprising a motor and a string having threads in more or less parallel, twisting around each other, between the motor and a load), or a split in case there is one, in between the threads, wherein the threads are prevented from being twisted by the split towards the load, wherein the string has different thread diameters at different portions of the string along its length, between the motor and the load or between the motor and a split if such is used.
A twisted string actuator for converting a rotational motion to a linear motion, comprising a motor and a string to be connectable to a load, wherein the string comprises three looped thread sections of which sections closest to the motor and the load comprise more than one loop of the threads, respectively.
