Definitions

  • the invention relates to a blower in the radial design of a heating and / or air conditioning system, in particular a motor vehicle with a motor holder holding the electric motor, on the outside of which project arms which are fastened to the blower inlet ring and also to the blower housing via damping elements.
  • the object of the invention is to improve a fan of the type mentioned in such a way that vibrations of the motor and fan wheel are not transmitted to externally connected parts.
  • the fastenings between the inlet ring and the blower or system housing be arranged on the outside of the inlet ring and the fastening between the motor holder and the inlet ring on the inside of the inlet ring.
  • the damping elements are moved far inward and then close to the origin of the vibrations, so that they are optimally absorbed.
  • the damping elements of the fastening between the motor holder and the inlet ring are peg-shaped or pin-shaped and are held with one side in a form-fitting manner in openings in the arms of the motor holder and with the other side in openings of the inlet ring.
  • the fastening between the motor bracket and the inlet ring is carried out solely by the damping elements, without requiring additional fastening means such as screws.
  • the cylindrical Damping element has coaxial ring grooves at both ends, with which it lies in bores / openings of the motor holder and the inlet ring.
  • the axis of the cylindrical damping element is parallel to the motor axis.
  • An additional securing of the fastening of the damping elements is achieved if the damping element is surrounded at least at one of its ends by a locking cap which ensures that the damping element is held in the bore / opening.
  • An electric motor (not shown) with the axis 1 drives an impeller (not shown) of a blower 2, which sucks in the air axially and releases it radially.
  • the impeller coaxially surrounds the electric motor.
  • the electric motor is coaxially bypassed by a cylindrical, in particular pot-shaped, motor holder 3, which has three radial arms 4 on the side with which the blower is attached to a heating and / or air conditioning system of a motor vehicle, which arms are formed on the motor holder 3.
  • a circular opening 5 is made in each arm 4, the edge of which is in an annular groove 6 an elastic damping element 7, in particular made of rubber or soft plastic.
  • the pin-shaped or pin-shaped damping element 7 has a greater axial length L than the width or diameter D. It has an annular groove 6 at both ends, the edge of an opening 8 lying in the second annular groove, which is arranged in a projection 9 of an inlet ring 10.
  • the damping element 7 thus forms a connection between the arm 4 of the motor holder 3 and the projection 9 of the inlet ring 10, without further fastening means such as screws being required at this connection point.
  • a secure and vibration-reducing hold is achieved solely by the positive connections of the two parts 4 and 9 via the two ring grooves 6 at both ends of the damping element 7.
  • the damping elements 7 are located in the inner region of the metal inlet ring 10, while the fastening points of the inlet ring 10 are on the outside of the heating and / or air conditioning system, in particular on its housing. These outer fastening points are created by four arms 11, which are formed radially on the outside of the inlet ring 10. The three arms 4 of the motor holder 3 are in angular positions that do not match the four arms 11. This leads to a further reduction in the transmission of vibrations.
  • locking caps 12 can be attached at this point, which serve as additional security. These locking caps overlap one end of the damping element 4 and pass through the opening 5.
