Title: Rolling tool for gear
Inventor: TSUKAMOTO RIYUUICHI
IPC: B21H5/00
Filed: 1982-04-05
Abstract: PURPOSE:To form a tooth part with a small thrusting force and a high thrusting speed by forming the peak surface in the roughly deformed region of rolled teeth of plural systems in a climbing staircase shape and arranging the peak surfaces of the respective steps on a circular conical coil-like curved surface. CONSTITUTION:The distance between the centers of both tools R3 and R4 is slightly narrowed and a blank gear material W2 is sandwiched between the tools. When the three of R3, R4, W2 are rotated synchronously, a rugged part is formed by plastic deformation on the outside circumferential surface. The material W2 is thereafter thrusted into a rough deformation region A. The rate of thrusting in this case is made the same as the pitch P of the region A. The peak surfaces 21, 22-2n with gradually increasing addendum of rolling teeth 1 gnaw in the recess on the outside circumferential surface of the material W2 and the teeth parts of the addendum increasing gradually from the front side in the rotating direction to the rear side are built up between the adjacent peak surfaces. The roughly shaped material W2 is thrusted into the region B and the thrusting is ceased in said position, whereby the gear is finished to a prescribed size under roration.

Abstract: PURPOSE: To attain to equalize a gas stream passing through an absorbent layer by a method wherein the vicinity of the folded part of a folding-screen shaped absorbent layer arranged to a substantially vertical direction against a gas stream is removed in a tapered form toward a thickness direction and a guide blade and a partition plate are provided thereto.  
     CONSTITUTION: The width of the side plate 102 of an absorbent layer 1b is made narrow and the part of the absorbent layer 1b contacted therewith is eliminated in a tapered shape to form an eliminated part 104 as well as an appropriate guide blade 105 is provided to the outer surface of the absorbent layer 1b and a partition plate 106 extending from said guide blade is provided to the inside of the absorbent layer 1b. A large amount of sucked air flows thereinto from a suction port 100 and a part thereof collides with the side plate 102 but, because the width of the side plate 102 is made narrow, most of air flows into the largely opened space between the absorbent layers 1b compared to a conventional apparatus and smoothly flows thereinto without generating eddy stream. Because fluid loss in a flow passage other than the absorbent layer itself is reduced, channeling of air is reduced and water making efficiency of the water making apparatus is enhanced.
