Abstract
A linear actuator has a screw threaded shaft member and an internally screw threaded member, the threadform of the shaft member corresponding to that of the internally screw threaded member but of smaller diameter, whereby the member may be skewed relative to the shaft so that the threads of the members will engage on a diameter smaller than the diameter of the member, means being provided to rotate one of the members, the other member being mounted so that it is freely rotatable.
Claims15
The linear actuator comprising a screw threaded shaft member and an internally screw threaded member, the threadform of the shaft member corresponding to that of the internally threaded member but of smaller diameter, drive means being provided for rotation of one of the members, the other member being mounted so that it is freely rotatable and will rotate with the driven member, means being provided to skew the axis of one member relative to the axis of the other member, so that the screw threads of the members engage at diametrically opposed positions.
