Definitions

  • a blade for the impeller of a fan in which an existing of a tough, high-strength material inner support member of an outer part made of aluminum or a comparable light metal alloy is umgössen such that it is embedded therein.
  • the inner support member in turn consists of two plates, which are inserted into each other by slots formed in each plate in such a way that they are at a right angle to each other in the direction of the blade axis.
  • the known bucket is connected to the hub by moving between two Hub bodies is clamped by pressing.
  • the two hub body must be available as castings disadvantageously or they must be designed costly as a welded construction. This is unfavorable in particular for the individual production of large fans or for small batches.
  • the fastening means are designed for casting with a blade portion of a fan blade.
  • the fastening means according to the invention can be used to fasten solid cast fan blades to the corresponding fan hubs.
  • the connecting portion is configured substantially flat and / or plate-like and / or conical.
  • a plate-like configuration of the fastener allows the production of a tensile connection with the fan blade when the fastener is potted with the fan blade.
  • the tensile connection between the blade section of the fan blade and the connecting portion of the fastening means is made particularly secured if at least one of the substantially aligned in the radial direction boundaries of the connecting portion in the axial and / or radial projection a has a curvy course.
  • the connection of the fastening means for example made of steel, by means of casting with a blade section of a fan blade, which is made, for example, of aluminum, is thereby rendered particularly durable.
  • the edges may have serrations or the like.
  • the fastening means have a base portion adjoining in the radial direction to the connecting portion with a substantially radially extending elongated fastening element for fastening a fan blade to a fan hub, the fastening of the fan blade with the aid of the fastening means according to the invention to the fan hub very cheap.
  • the fastener may be configured as a bucket pin with a straight or conical seat.
  • the radially extending fastening element can be designed as a turned blade bolt.
  • the bucket pin may be integrally formed with the connection portion of the attachment means or welded to the connection portion, for example.
  • the hub can therefore be designed in one piece cost, wherein only in the radial direction receiving holes for inserting the

  • the fastening part 3 consists of a connecting portion 5 and a base portion 4.
  • the connecting section 5 and the base section 4 each consist of a soft steel of strength class 5.6.
  • the connecting portion 5 has the shape of a flat plate.
  • the edges running essentially in the radial direction of the blade section 2 during installation each have a number of serrations 6.

Abstract

L'invention concerne des moyens de fixation (3) destinés à la fixation d'une section (2) d'une pale (1) de ventilateur, en particulier d'un ventilateur pour l'évacuation des fumées, sur un moyeu de ventilateur, offrant une résistance élevée à la traction, y compris aux températures élevées, les moyens de fixation (3) et les pales de ventilateur (1) devant être fabriqués à un poids aussi faible que possible. A cet effet, l'invention est caractérisée en ce que les moyens de fixation (3) présentent une section d'assemblage (5) configurée pour la production d'une liaison résistant à la traction, avec une section (2) d'une pale de ventilateur qui peut être agencée essentiellement à l'intérieur de la section (2) de pale.
