Abstract:
The arrangement is applied to a compressor which comprises: a crankcase (40), carrying a cylinder (41) provided with a lateral slot (42) and in which is housed a piston (10) provided with two radial holes (11) and with an eccentric axial hole (12); a connecting rod (20) connected to a crankshaft (30) driven by an electric motor (50) and having a smaller eye (21) mounted in the piston (10); and a wrist pin (60) having a first end (61) turned to the bearing hub (43) of the crankcase (40), a second end (62) turned to the lateral slot (42) of the cylinder (41) and a diametrical hole (63), adjacent to the second end (62) in which is provided an engaging means (64), for the axial and rotational coupling of a tool (80) for mounting and indexing the wrist pin (60), in the interior of the piston (10), in a position in which the diametrical hole (63) is axially aligned with the eccentric axial hole (12), so as to allow an elastic pin (70) to be introduced in said diametrical hole (63) and in said eccentric axial hole (70).
Abstract:
Vorgeschlagen wird ein zweiteiliger Kolben (1) für einen Verbrennungsmotor mit einem Oberteil (2), das auf der Unterseite seines Kolbenbodens (4) einen Bolzen (31) mit einem Außengewinde (32) aufweist, und mit einem Unterteil (3), das ein Bodenteil (25) aufweist, an das radial innen eine in axialer Richtung elastisch dehnbaren Dehnhülse (26) angeformt ist, in die zum Verschrauben des Oberteils (2) mit dem Unterteil (3) der Bolzen (31) eingeführt ist, wobei die Dehnhülse (26) in axialer Richtung gedehnt wird. Das Material der Dehnhülse (26) weist zur Verbesserung ihrer Festigkeit eine gegenüber dem restlichen Kolbenmaterial höhere Streckgrenze auf. Die Erhöhung der Streckgrenze wird durch eine bleibende Dehnung der Dehnhülse in axialer Richtung von näherungsweise 1 % ihrer Länge erreicht.
Abstract:
The invention relates to a wind turbine blade with strain sensing means. The blade comprises a surface structure, a block sensor unit including optical sensor means for sensing strain in the blade, and an intermediate connection plate positioned in between said optical sensor means and said surface structure. The intermediate connection plate is adhesively connected to said surface structure and connected to said optical sensor means. The modulus of elasticity of said intermediate connection plate is similar to or less than the modulus of elasticity of said surface structure. The invention also relates to a wind turbine, block sensor unit and uses hereof.
Abstract:
An enhanced elastomeric stator assembly and method of making the same is disclosed. The elastomeric stator may be structurally, thermally, and/or chemically enhanced through the incorporation of graphene particles, cross-linkable polymers, coupling agents that extend cross-links, and by the reduction of filler material. The graphene particles can be incorporated in functionalized or non-functionalized form or in a combination thereof, the functionalized graphene increasing the number of cross-links in the overall structure, thereby enhancing the structural robustness of the elastomeric stator. The compound can be formulated to have a relatively low viscosity and other characteristics that allow the material to flow through a mould cavity.
Abstract:
Die Erfindung betrifft eine Flüssigkeitsring-Vakuumpumpe mit einem Pumpengehäuse (20) und einem exzentrisch in dem Pumpengehäuse (20) gelagerten Flügelrad (14). Erfindungsgemäß besteht das Flügelrad (14) aus einem Material, dessen Elastizitätsmodul kleiner als 4000 N/mm 2 ist. Die Erfindung betrifft außerdem ein Flügelrad (14) für eine solche Pumpe. Mit dem erfindungsgemäßen Flügelrad wird es möglich, die Pumpe näher an der Kavitationsgrenze zu betreiben.
Abstract:
A flexible flange (300) for a blade root wall (302) allows movement of the blade root (209) toward and away from the bulkhead (304). The flexible flange provides flexibility and support for the blade wall and also provides a sealant, thereby protecting the machinery in the hub (110). The flexible flange has a top portion (306) configured to be secured to a blade root wall, a bottom portion (310) configured to be secured to a bulkhead (304) and an angled portion (308) configured to offset the top portion from the bottom portion, a gap (312) being between the blade root wall and the bottom portion to allow for movement of the blade root wall toward and away from the bulkhead.
Abstract:
The inventive stator includes a helical cavity component made from a material chosen to reinforce an elastomer liner deployed thereon. The contouring of the elastomer liner is asymmetrical, such that the elastomer liner is relatively thick on the loaded side of a lobe as compared to its thickness on the unloaded side of the lobe.
Abstract:
An apparatus for use in a wellbore may include a stator having a bore and a rotor disposed in the bore. Either or both of the rotor and the stator may include a layer that has an asymmetrical material property profile along at least a portion of a circumference of that layer.
