Definitions

the invention relates to a wind sifter with a rotating classifying wheel against which it is blown by the classifying air from the outside inwards, with ring-shaped blades that run parallel to the axis of rotation and are arranged between a circular disk carrying the classifying wheel hub and an annular cover plate. It relates to a classifying wheel for such an air classifier, which is made entirely of a wear-resistant sintered material.
a classifying wheel of the required type has become known, for example, from DE-PS 41 40 656.
the circular disk with the hub, the cover disk and the blades arranged between them and running parallel to the axis of rotation are produced in one piece.
the bore in the hub is machined with a groove which is semicircular in cross section to receive a correspondingly shaped key for torque transmission to a finished size for the direct mounting of the classifying wheel on its drive shaft.
the flow channels between the blades are formed by surfaces of the blades which run parallel to one another and in the direction of the axis of rotation and which are connected to one another in the transition region to the circular disk or cover disk by an arcuate surface.
a classifying wheel which is composed of simply designed cylindrical ring elements which are connected to one another by a filler which is introduced into joints between the ring elements and which solidifies and which are machined and balanced to finished dimensions before being assembled.
the filler can be an adhesive or a solder with a joint width of up to 0.1 mm.
the main part of the classifying wheel is a piece of pipe, the outer dimensions of which determine the main dimensions - diameter and height - of the classifying wheel.
the axial position of the circular disc and cover plate can be determined by an annular stop surface machined into the pipe section or by designing the surfaces delimiting the soldering or adhesive joints as conical surfaces.
the connection of the hub and the circular disk is carried out in a corresponding manner.
the advantage of the training shown is that critical stress areas, especially in the transition area between the circular disk and the pipe section, can be eliminated or defused to such an extent that the stresses that occur remain in the safe area and the risk of breakage as a result of crack formation is eliminated.
a higher manufacturing accuracy, especially with classifying wheels with outer diameters of more than 250 mm, is achieved in that the individual parts are designed as simply designed ring elements that can be inexpensively machined and balanced before they are assembled.
the classifying wheel 1 consists of a hub 2, a circular disk 3, a cover disk 4 and a pipe section 5. All these parts are made of a sintered material and are mechanically processed (preferably ground) and balanced before being assembled to the finished size. Since these are simply designed ring elements, high manufacturing accuracy is achieved.
the pipe section 5 is provided at both ends with recesses which are centered with respect to the axis of rotation 6 and which serve to accommodate circular disk 3 or cover disk 4 and a width corresponding to Have thickness of the received disc, so that there are flat, stepless end faces on both sides of the classifying wheel.
the hub 2 the bore of which is provided with a feather keyway which is semicircular in cross section, is inserted centrally into the circular disk 3, its axial position being determined by its stepped outer circumference.
An adhesive is used to connect parts 2, 3, 4 and 5, e.g. a two-component adhesive that is filled into the joints 10, 11 and 12 when the parts are joined together.
