Definitions
- the invention relates, according to the preamble of claim 1, to a rotor for a comminution machine, which consists of a plurality of disks which are non-rotatably fitted on a shaft, of rotatable hammers distributed between them, and of the protective caps covering the rotor against wear.
- Such rotors were already known from DE 26 05 751 AI and finally further developed according to DE 43 43 801 AI into a wearing part system.
- the external protective caps which cover the outer disks of the rotor, are of particular importance in the system of the rotor as a tool and at the same time a system of the shredding machine to be protected.
- outer protective caps are initially to be classified as inactive wear parts, like the other protective caps, they have to perform additional functions as a result of specifically acting forces.
- US 42 22 530 shows that the protective caps covering the outer disks of the rotor are decoupled from the forces of the hammers and the hammer axes and from the forces introduced directly onto the outer protective caps by the hammers, the protective caps engaging around the disc and by means of at least one connecting element are non-positively attached to the disc.
- the invention has for its object to provide a rotor for a comminution machine, which consists of several disks rotatably mounted on a shaft and from between distributed hammers, which are rotatably mounted on parallel to the shaft eccentrically through the disks hammer axes and at least the parts of the rotor exposed to secondary wear with their circular segment-shaped part covering protective caps, which are fastened with their bearing hubs between the disks on said hammer axes.
- the rotor is to be formed by the protective caps with their circular segment-shaped parts to form an essentially roller-shaped casing with perforations for swinging through the hammers which are arranged offset with respect to one another, the disturbing forces of the hammers and hammer axes largely being eliminated and a material-saving and inexpensive fastening of the outer protective caps the discs are guaranteed.
- the outer ones bordering the inner protective caps Protective caps are non-positively attached to the outer pane by means of at least one connecting element such as an Allen screw.
- a locking piece which is also attached directly to the disk, secures and limits the axial position of the respective hammer axis in the disk.
- connecting elements are used from this side, primarily hat-shaped nuts, positively or non-positively secured, the hat surface of which forms a plane with the inner surface of the washer.
- the features according to the invention represent a rotor which creates a clear quality advantage in terms of its design, as well as its technological manufacture and application.
- FIG. 1 shows the rotor in section A-A according to FIG. 2,
- FIG. 2 shows the rotor of FIG. 1 in a side view
- Fig. 3 shows an outer protective cap with a ring segment-shaped projection a) in side view, b) with a partial section of the positive attachment
- Fig. 4 shows an outer protective cap without a ring segment-shaped projection a) in side view, b) with a partial section of the non-positive fastening.
- a rotor 1 for a hammer crusher which essentially consists of a plurality of disks 3 mounted non-rotatably on a shaft 2 and of hammers 4 distributed between them.
- the hammers 4 are rotatably mounted on hammer axes 5 which are guided parallel to the shaft 2 through the disks 3.
- At least the parts of the rotor that are exposed to secondary wear are covered with the circular segments 6.4 of the protective caps 6.
- These parts 6.4 form an essentially roller-shaped casing 7 with perforations 7.1 arranged to be offset with respect to one another for swinging through the hammers 4.
- the protective caps 6.1 covering the outer disks 3.1 of the rotor 1 are decoupled from the forces of the hammers 4 and the hammer axes 5 and from the forces introduced by the hammers 4 directly onto the protective caps 6.1.
- the protective caps 6.1 are fastened directly to the disks 3.1 by means of the webs 6.2 encompassing the outer edge of the disks 3.2.
- the respective web 6.1 has a cutout 6.3 (FIGS. 2, 3 and 4) which partially includes a closure piece 8 which is also directly attached to the disk 3.1 (FIG. 2) and which defines the axial position of the respective hammer axis 5 in the disk 3.1 limits and secures.
- 3a, b is the protective cap 6.1 exposed to the lateral forces of the hammers 4 via a ring segment-shaped projection 6.5 which is in a shoulder 3.2 of the disk 3.1 engages, and positively connected by means of at least one Allen screw as a connecting element 10, which sits with its head on the threaded bore in the disk 3.1. There is a game between the head and its flange-like approach and the correspondingly offset hole in the web 6.2.
- the protective cap 6.1 bordering on the relevant inner protective cap 6 is non-positively fastened with its web 6.2 to the disk 3.1 by means of at least one Allen screw as a connecting element 10, which therefore has a flange-like attachment of the head in the correspondingly offset bore in the Web 6.2 sits on.
- a technologically favorable embodiment according to FIGS. 1 and 2 provides that a disk 3.3 is connected to the outer disk 3.1, which follows the contours of the webs 6.2 and the closure pieces 8 visible in FIG. 2, which in the opposite of the disk 3.1 resulting recesses, the locking pieces 8 and the webs 6.2 are embedded, that a practically flat surface is created without protruding parts.
