    • A radial shaft sealing ring for sealing of a casing part of a motor vehicle engine or gearbox, with a supporting body and a sleeve-type sealing lip connected to the supporting body and bent towards the side to be sealed, which sealing lip lies on an axial length L on the shaft and has a conveying groove in the area of contact with the shaft for conveying of medium back into the volume to be sealed, and which sealing lip has a sufficient bending elasticity to achieve a sufficient contact pressure without the use of additional means, wherein the material of the sealing lip essentially consists of a high temperature cross-linked LSR liquid silicone material.

    • The introduction of undesired intermetallic phases (IMP) is reduced in lead-free solder joints. For this purpose, solder pastes are prepared, which have a metal powder mixture that generates a melting range of at least about 5° Kelvin and preferably less than about 30° Kelvin. Suitable for this purpose are metal powder mixtures, in which the melting points of the metal powder components lie apart from each other more than about 5° Kelvin, particularly more than about 10° Kelvin, preferably more than about 15° K, and optionally less than about 30° Kelvin, particularly up to about 25° Kelvin. However, metal powder mixtures are also possible, in which the melting point spread can equal about 100° Kelvin and more, if the higher melting component dissolves in the melt below the melting point of this component, so that the melting range can be held under about 30° Kelvin. With these solder pastes undesired intermetallic phases can be held nearly arbitrarily low.
    • 在无铅焊点中引入不期望的金属间相(IMP)。 为此,制备焊膏,其具有产生至少约5开氏度,优选小于约30开氏度的熔融范围的金属粉末混合物。 适合于此目的的是金属粉末混合物,其中金属粉末组分的熔点彼此分开超过约5°开尔文,特别是大于约10°开尔文,优选大于约15°K,并且任选地较少 高于约30°开尔文,特别高达约25°开氏度。 然而,金属粉末混合物也是可能的,其中熔点扩散可以等于约100开氏度和更高,如果较高熔点的组分溶解在低于该组分的熔点的熔体中,使得熔融范围可以保持在 约30°开尔文 对于这些焊膏,不期望的金属间相可以几乎任意低。

    • A shaft sealing ring for a shaft comprises a sealing lip made of an elastomeric material or a PTFE compound and dimensioned as to be flaccidly bendable. The flexural elasticity is selected such that it will just be sufficient to press a sealing portion of the sealing lip into sealing engagement with the periphery of the shaft. The sealing portion of the sealing lip engages the periphery for a predetermined length. In the sealing portion, the sealing lip is provided along its circumference, at the side of the shaft, with endless, undulating return channels at least throughout this length. These channels return any medium escaping during rotation of the shaft to the space to be sealed. The return channels do not communicate with the surroundings of the shaft sealing ring. No seperate contact pressure means, such as a helical ring coil spring is required to press the sealing lip into engagement with the shaft.
    • 用于轴的轴密封环包括由弹性体材料或PTFE化合物制成的密封唇缘,并且其尺寸设计为易于弯曲的。 选择弯曲弹性,使得仅将密封唇的密封部分压紧到与轴的周边密封接合就足够了。 密封唇的密封部分与周边接合预定长度。 在密封部分中,密封唇沿其圆周方向设置在轴的侧面,至少在整个长度上具有无尽的,起伏的返回通道。 这些通道在轴的旋转期间返回任何介质逃逸到待密封的空间。 返回通道不与轴封环周围通讯。 不需要单独的接触压力装置,例如螺旋环螺旋弹簧来将密封唇压紧以与轴接合。
