To provide a pipe grooving device.SOLUTION: A device for forming circumferential grooves in pipe elements uses multiple geared cam bodies mounted on a carriage which rotates about a fixed pinion. The gears engage with the pinion which causes the geared cam bodies to rotate relative to the carriage. Traction surfaces and cam surfaces on the cam bodies traverse the outer surface of the pipe element and impress a circumferential groove therein. To substantially prevent rotation of the pipe element, the pitch circle diameter of the pinion equals the outer diameter of the pipe element, and the pitch circle diameters of the traction surfaces equal the pitch circle diameters of the gears.SELECTED DRAWING: Figure 1 【課題】パイプ溝切デバイスの提供。【解決手段】円周方向溝をパイプ要素内に形成するためのデバイスは、固定ピニオンを中心として回転する、キャリッジ上に搭載される、複数の歯車付きカム本体を使用する。歯車は、ピニオンと係合し、これは、歯車付きカム本体をキャリッジに対して回転させる。カム本体上の牽引表面およびカム表面は、パイプ要素の外側表面を横断し、円周方向溝をその中に圧造する。パイプ要素の回転を実質的に防止するために、ピニオンのピッチ円直径は、パイプ要素の外径と等しく、牽引表面のピッチ円直径は、歯車のピッチ円直径と等しい。【選択図】図１
