Abstract
PURPOSE: To perform safe and sure removal of heavy material at a long distance by simple structure by combining a screw wheel with the reverse-L type section of a screw thread with a frame-type rack block in the same pitch as the of the screw and having punched hole racks and the radius of its circular arc corresponding to the radius of the screw wheel.
CONSTITUTION: A power transmission system is constituted by combining a screw wheel 1 whose section is made to be of reverse-L type by downward projects 3 provided on a screw thread 2 with a frame-type rack block 4 with flanges 7 for fitting formed on the right and left sides thereof. The rack block 4 is prepared by punching plural number of lines of hole racks 6 having the radius R of its circular arc corresponding to the radius R of the screw wheel 1 in the range of the whole pitch through a sheet metal 5. By this, male and female screws are engaged in a part along the circular arc without engagement thereof along all the periphery as it is the case with the existing screw system, and moreover, in the course of the operation, as the projects 3 of the reverse-L type are caught by the edge of the hole racks 6, the screw wheel 1 rotates under the load in the direction of gravity, going and coming in the shearing manner along an axis of wheel 9 safely and surely, employing the frame-type rack block 4 as a rail.
