Definitions
- the present invention relates to a fan hub, comprising means for connecting to a fan shaft and a substantially cylindrical mounting portion with radial seats for a number of fan blades, wherein the mounting portion has an inner circumferential surface.
- the invention also relates to a reinforcing element for use with a fan hub, having means for fastening a number of fan blades in a tensile strength.
- the invention relates to a method for producing a
- Fans for subways or tunnels and / or closed vehicle buildings such as underground garages must work reliably over very long service lives under a wide variety of load and ambient conditions.
- the installation of fans in subways or tunnels or underground car parks is designed for operation over several years or decades.
- the metro or tunnel operator has requirements for the operability of the ventilator at high temperatures, such as occur especially in cases of fire. The requirements are partly prescribed by law.
- fans consist of their basic construction of a fan hub to which a number of fan blades is mounted radially.
- the Attachment of the fan blades is done by means of fasteners such as bolts.
- fan hubs are known that consist of solid aluminum or an aluminum alloy.
- a disadvantage of fan hubs made of aluminum is their limited substitutability at temperatures above about 300 0 C. Because the tensile strength of aluminum decreases sharply at the temperatures mentioned, so that the aluminum begins to flow gradually. Even special aluminum alloys are not able to significantly improve this inadequacy. As a result of this detrimental nature of aluminum, fan blades may be released from a fan hub made of aluminum at high temperatures, such as may occur in fires.
- fan hubs made of aluminum Due to this inadequacy of fan hubs made of aluminum, fan hubs made of solid steel are used in the prior art for smoke exhaust fans at high loads, ie at high speeds and / or with large blade lengths.
- steel fan hubs have the disadvantage of having a very high mass.
- the invention is equally based on the object, a reinforcing element for use with a fan hub of Specify mentioned type, with the help of the mentioned disadvantages of the prior art can be avoided.
- the present invention is based on the object to provide a method for producing a fan with a fan hub according to one of claims 7 to 11.
- this object is achieved in a fan hub of the type mentioned by the fact that a substantially separate from the mounting portion, substantially annularly closed reinforcing element is provided with means for tensile fastening of the fan blades. It is therefore within the scope of the invention to add a reinforcing element in the form of an additional component to the fan hub.
- the reinforcing element is configured substantially annular, the reinforcing element can absorb radial forces and completely keep away from the Axiallaufradnabe example made of aluminum. In the case of balanced fans, the reinforcing element exerts no force on the fan hub.
- the hot tensile strength of the unit fan hub and reinforcing element is determined solely by the material of the reinforcing element.
- a material optimized for the purpose of tensile fastening of the fan blades to the fan hub can be selected in this way.
- a material optimized for the actual fan hub can be selected.
- the reinforcing element can be advantageously selected from a material with high hot tensile strength and good creep behavior at high temperatures. According to the invention for the fan hub a particular lighter material without affecting the overall hot tensile strength of the fan.
- the reinforcing element has at least two segments which can be welded together.
- the production of a fan hub, which is provided with a reinforcing element according to the invention, is particularly simple due to this measure.
- the number of segments corresponds to half the number of fan blades to be accommodated.
- a fan with a total of four fan blades two segments may be provided.
- three segments may be provided.
- four segments can accordingly be provided.
- the attachment of the reinforcing element according to the invention to a fan hub is further improved if, in an embodiment of the invention, the reinforcing element has at least one substantially planar section whose surface normal can be oriented in the radial direction of a fan hub when used as intended.
- the number of planar sections corresponds to twice the number of fan blades to be accommodated.
- the number of planar sections corresponds to twice the number of fan blades to be accommodated.
- in a four-wheel eight-plane sections exist. Due to the generally to be demanded symmetry of the rotating structures results in a cross-sectional area of the substantially annular reinforcing element corresponding to an n-corner.
- a six-wheel would have twelve plane sections, a six-wheel eight-way wheel and a twelve-wheel impeller twenty-four planar sections.
- Reinforcement element is essentially made of steel.
- the hot tensile strength at the temperatures mentioned is much better than that of aluminum.
- a fan hub with means for connection to a fan shaft and / or a hub core and a substantially cylindrical mounting portion with radial seats for a number of fan blades, wherein the mounting portion has an inner circumferential surface, which with one of the fastening portion substantially separately configured, substantially annularly closed reinforcing element is provided with means for tensile fastening of the fan blades.
- the substantially annular attachment portion can be made with advantage of a material with higher tensile strength than the fan hub, moreover.
- the attachment portion may for example have the shape of a bent steel belt.
- the means for tensile fastening of the fan blades can be holes with or without thread in the simplest case.
- the fan hub according to the invention is further improved if the reinforcing element is arranged substantially along the inner circumferential surface of the fastening section.
- the interior of the fan hub is usually free of superstructures. Therefore, according to the invention can be retrofitted with advantage according to the invention, a reinforcing element, such as in the form of a bent steel belt without constructive adjustments of the impeller hub are required.
- the cylindrical mounting portion of the hub may need to receive additional radial forces to hold the reinforcing member in position.
- the flat areas can be made for example by milling.
- the fan hub is essentially made of aluminum.
- aluminum is the preferred material for an axial impeller hub.
- a fan hub made of aluminum despite the unfavorable properties of aluminum in terms of hot tensile strength in conjunction with a reinforcing element according to the invention have the required hot tensile strength. Because the reinforcing element can be made simultaneously of steel within the scope of the invention.
- the reinforcing element according to one of claims 1 to 6 configured.
- the process object underlying the present invention is achieved by a method for manufacturing a fan with a fan hub according to one of claims 7 to 11, in which
- Fan hub is approximated such that the means for tensile fastening with the radial receptacles of the cylindrical mounting portion in the radial and axial direction coincide;
- Fan blades are inserted into the radial receptacle of the cylindrical mounting portion and in the means for tensile fastening;
- each segment of the reinforcing member is screwed to the cylindrical attachment portion of the fan hub by means of the threaded bolt of the respective fan blade to be fastened;
- the inventive method allows retrofitting of conventional, made of aluminum Axiallaufradnaben or other hubs for fans with a reinforcing element according to the invention. Because the ring shape of the steel element only by welding of individual segments of the Reinforcement element is carried out after attachment of the individual segments with the hub, eliminating a possibly problematic fitting a one-piece reinforcing element, in which, for example, a fan hub made of aluminum could be damaged by scratches. In addition, by the manufacturing method according to the invention with reinforcing element consisting of individual segments, an optimum fitting of the reinforcing element to the inner lateral surface of the fan hub can be achieved.

- the attachment of fan blades by inserting the blade bolts in the radial mounting holes 6 in the cylindrical attachment section 4 of Axiallaufradnabe 1 and then screwing the threaded shovel bolt takes place based on an attached to the inner circumferential surface 5 nut.
- Receiving bores 6 is followed by a conically tapered jacket section 11. If the Axiallaufradnabe 1 is made of aluminum, this arrangement, however, at temperatures such as occur at tunnel fires, ie at 300 0 C to 400 0 C, an insufficient tensile strength.
