摘要:
A sealing system including a rotary sealing surface on a rotary shaft and a rotary shaft lip seal, of which the rotary sealing surface has a surface coating layer of a solid lubricant substance. The invention further includes an industrial robot having several axes of rotation, including a manipulator with drive units for rotating robot parts according to the axes of rotation of the robot, and at least one of the drive units having a rotary shaft provided with such a sealing system. In addition, the invention includes a method for providing a rotary sealing surface on a rotary shaft, including coating the intended sealing surface of the rotary shaft with a surface coating layer of a solid lubricant substance.
摘要:
Heat exchange device with a boiling surface comprising a porous surface layer arranged on a solid substrate, the porous surface layer comprises a porous wall structure defining and separating macro-pores that are interconnected in the general direction normal to the surface of the substrate and have a diameter greater than 5 μm and less than 1000 μm wherein the diameter of the pores gradually increases with distance from the substrate wherein the porous wall structure is a continuous branched structure.
