SCREW-TYPE ADDING MECHANISM

Click to enlargeClick to enlarge Description

Link 1 is a hollow shaft on which a screw thread of large pitch has been cut. Link 1 rotates about fixed axis x-x. Shaft 3 rotates about axis x-x and passes through link 1. Link 6 slides in fixed guide p and is connected by turning pair A to link 2 which, in turn, is connected by a screw pair to link 1. One of the addends a is entered by the sliding motion of link 2. The magnitude of this addend is indicated on scale 4 by means of link 5. The second addend b is entered by turning shaft 3 which is connected to hollow shaft 1 by means of pins k which enter holes in the flanges of shaft 1. The magnitude of the second addend is also indicated on scale 4 by subsequent displacement of link 5. The sum c=a+b is obtained as the result of the two displacements.
