Definitions
- the invention relates to a
- the invention has for its object to provide a drive sprocket of the generic type, which can withstand the forces that occur without tearing the connecting screws.
- feather-like means are used in the separation point of the sprocket sections, which bridge the parting line. It is preferably provided that the feather-like means consist of bolts arranged at each separation point, which are inserted into matching recesses which are directed parallel to one another and parallel to the direction in which the sections are joined.
- the feather-like means consist of profile bars, in particular square or rectangular cross-section, which engage in recesses of the two sections directed axially parallel to the sprocket axis, the direction of use of the profile bars in the recesses running parallel to the direction of assembly of the sections.
- the profile bars are aligned with their longitudinal axis parallel to the sprocket axis in order to achieve the greatest possible support effect.
- the feather-key-like means can each be inserted halfway through their cross section or their length into a recess in each of the two sections.
- feather key means in the toothed middle part of the chain wheel are arranged.
- the configuration according to the invention prevents the separation point from bending open when the chain is loaded.
- the effect occurring in the prior art that the sprocket sections lift off at the separation point during the rotation is prevented by the arrangement of the feather-like means in the separation point.
- the connecting screws are largely relieved of bending forces and mostly only loaded under tension, so that the risk of the screws being torn off is largely prevented.
- the arrangement of auxiliary fitting screws makes it easier to remove the parallel key means, and the auxiliary auxiliary screws can simultaneously serve to pre-fix the parallel key means on one of the two sprocket sections (segments).
- Figure 1 is a drive sprocket in side view, partially broken away.
- FIG. 2 shows the sprocket
- the drive sprocket shown in the drawing for continuous chain conveyors in mining consists of two sprocket sections (segments) 1, 2 with radially directed separation points 3.
- the sprocket sections have axial extensions 4 on both sides of the central area, which can be connected by means of tangentially directed connecting screws, which is the case with 5 is indicated.
- elastic deflection is prevented of the segments at the separation point 3 in the separation point key-like means 4 used.
- profile rods of square cross-section are provided in the exemplary embodiment as feather-like means 4, which engage in recesses 6, 7 of the two sections 1, 2, which are directed axially parallel to the sprocket axis 5, at the separation point.
- the direction of use of the Profil ⁇ rods 4 is parallel to each other and parallel to the direction of assembly of the sections 1,2, so that the sections can be joined together by parallel displacement and the feather-like means 4 engage in the corresponding recesses 6.7 with a snug fit.
- the feather-like means 4 are each half of their cross-section in the recess 6 of one segment 1 and in the recess 7 of the other segment 2.
- the feather-like means 4 are arranged in the toothed middle part of the sprocket.
- the feather-like means 4 can have auxiliary disassembly screws 8, by means of which they can be pushed out of the snug fit of the corresponding recess (in the exemplary embodiment of the recess 6).
- the invention achieves in a simple manner and without great effort that bending of the segments 1, 2 in the region of the separation point is avoided, so that the risk of tearing off the connecting screws 5 is considerably reduced, if not prevented.
