| 19 | Worm speed reducer, and manufacturing method for worm and worm wheel | US885701 | 1992-05-19 | US5279174A | 1994-01-18 | Kiyoji Minegishi |
| A worm speed reducer consisting of a worm made of a relatively hard material such as cast iron or steel and a worm wheel made of a relatively hard material such as cast iron. A material strength is set so that an amount of wear of the worm becomes larger than that of the worm wheel. A tooth surface of the worm wheel is formed with a network irregularity extending in both a direction of a cutting scratch due to cutting and a direction intersecting the direction of the cutting scratch, and also formed with a chemical conversion coating having a thickness smaller than a height of the irregularity. A tooth surface of the worm is formed with a network irregularity extending in both a direction of a cutting scratch due to cutting (or a grinding scratch due to grinding) and a direction intersecting the direction of the cutting scratch (or the grinding scratch) of the worm, and also formed with a chemical conversion coating having a thickness smaller than a height of the irregularity of the worm. Accordingly, seizure resistance can be maintained not only in an initial stage of operation but also after operating the worm speed reducer for a long period of time, irrespective of the use of low-cost cast iron. | ||||||
| 20 | Apparatus for cutting arcuately-shaped worms | US699760 | 1976-06-25 | US4037365A | 1977-07-26 | Carroll Richard Cole |
| An apparatus for cutting an arcuately-shaped worm includes a support shaft adapted to carry a worm blank thereon and journalled in a frame which is mounted for pivotal movement about a fixed axis so that the worm blank may be simultaneously rotated on its axis and arcuately translated about the fixed axis relative to a cutter. The shaft is rotated by a drive means, and arcuate translation of the shaft is provided by a worm gear which is journalled in the frame and driven off the shaft, with the worm engaging a fixed gear segment, so the rate of rotation and of arcuate translation are coordinated. | ||||||
