    Abstract: An apparatus for multi-bead welding of two rotating workpieces comprises a flat filler wire holder which can be introduced into the gap between the workpieces and which is periodically pivoted forth and back at substantially constant angular velocity between the two sides of the gap. The pivoting is effected by a motor which is started when a cam rotating in synchronism with the workpieces actuates a stationary signal generator. The cam is provided on a cam disc which is driven through a friction coupling and which, on each revolution, is arrested by a pawl during a period determined by an adjustable timer. The timer is started when the cam actuates a stationary signal generator mounted shortly in advance of the pawl, and after the expiry of the period of the timer the pawl is retracted so that the rotation of the cam disc can continue. The pawl is again advanced to operative position when the cam actuates the first mentioned signal generator.

    Abstract translation: 用于两个旋转工件的多珠焊接的装置包括扁平填料线保持器,其可以被引入到工件之间的间隙中,并且在间隙的两侧之间以基本上恒定的角速度周期性地向前和向后枢转。 枢转由马达实现,当与工件同步旋转的凸轮启动静止的信号发生器时,马达启动。 凸轮设置在通过摩擦联接器驱动的凸轮盘上,并且在由可调节定时器确定的时间段期间,每个转动由棘爪阻止。 当凸轮致动在棘爪之前不久安装的固定信号发生器时,启动定时器,并且在定时器的期间到期之后,棘爪缩回,使得凸轮盘的旋转可以继续。 当凸轮致动第一个提到的信号发生器时,棘爪再次前进到操作位置。

    Abstract: Method of laser hardening of a surface area of a workpiece, such as a surface of a journal of a crankshaft, comprising: generating a relative movement between the surface of the workpiece and a laser source to allow a laser spot to subsequently be projected onto different portions of said surface area, and during said relative movement, repetitively scanning the laser beam (2) so as to produce a two-dimensional equivalent effective laser spot (5) on said surface area. The scanning pattern can comprises at least three substantially parallel lines which the laser spot follow in a certain order. When the workpiece comprises several journals having different widths, two laser sources (1, 1A) may be used to harden the surface area of the wider journals.

    Abstract: 【課題】本発明は、一つの軸(10)と、この軸のための貫通孔をそれぞれ有する複数のカム(20〜26)を使用したカム軸の組立方法に関する。
    【解決手段】カムは、マガジン(40)内にしっかり詰められ、軸の貫通孔に関して同軸にかつ所定の回転位置で互いに相対的に位置決めされている。 軸は、積み重ねられたカム内に導入され、その中でその長手方向への移動により個々のカムに対して連続的に位置決めされる。 カムは軸に順次固定される。 カムに要求される回転は、軸がその長手方向に移動することによって、および、所定の角度だけ回転されることによって、容易に生ぜしめることができる。
