Description

polyester resin, reinforced with fiberglass, in order to install one place of a tooth clamp — and a large one; it can be separated from the free active tooth and fully use the gk: the strength of the teeth from en, saturated, polyfine resin, aluminum, groove, Bottom glass 01VOL by the window.

This is achieved by the fact that on the tooth holder and on the side distant from the end of the 3iyi6a, the connection is established by a clamp, additionally consisting of a flat link and flat 1ko; ntr0e, pin. In the Homutik .M joint, the tooth passing through the hole of the tooth holder and surrounded by an elastic sheath is made of an unsaturated polyester resin tooth reinforced with fiberglass.

In order to reduce the bending stress while simultaneously catching the limit ZZ (Weights (A tooth is attached to the tooth holder), a guide bushing is provided that covers the tooth with a gap. The guide bushing ends (output expansion, due to which, when the tooth is deflected, the shield disappears. It prevents it from breaking at the clamping point. When two teeth or more are fixed on a single tooth holder, a double or multiple connection is provided for each tooth. Flat earring and counter mount onoO the wives are nonslipped by grooves in which the teeth of M1 are a tooth of glass fiber reinforced unsaturated polyester resin.

 The redesigned tooth of the non-A) U; 1; polyester resin, ar, milled with glass fiber, surrounded by an elastic sheath, is clamped with a positive fit in a gripping sleeve having an output extension. For stolleni clamped with a geometric closure of the teeth of the gripper, the sleeve in its part, which protrudes beyond the tooth holder, is slotted so that the tooth is clamped by a connection with a buckle mounted on the tooth holder.

A simpler pattern is that the tooth is made of an unsaturated fiberglass-reinforced fiberglass dmola, pressed into an elastic molded piece, secured by protrusions on the molded part, an IB tooth holder. To maintain the bending strength of the teeth on the shaped part, an output expansion is provided. The invention has the advantage of providing long-lasting orcs of teeth made of unsaturated polyester resin reinforced with glass fiber, which, together with the attachment of the teeth, is more expensive than the metal teeth with locking elements used so far for this purpose. In addition, the teeth of an unsaturated polyester fiber reinforced resin, reinforced by the proposed

way, have a longer service life than metal teeth.

The next advantage is the prevention of breakage (K shredding; efficient aggregate 5 TOiB, meeting metal teeth lying on the ion. When meeting the teeth lying on the floor of an unsaturated polyester resin reinforced with fiberglass, no breakage of the shredder knives occurs.

0 The attached attachment has the further advantage that the tooth can be replaced without mounting the remaining teeth on the tooth holder. A tooth can be left protruding over the joint by a lug, so that, if necessary, it can be removed after wear of its end.

FIG. 1 shows the attachment of the teeth with (Hanging on (hangers; fig. 2 - the same, (VIEW from above; fig. 3 -

On the tooth holder 1 in the form of a pipe, at a distance from each other, several teeth 2 of glass fiber-reinforced unsaturated polyester resin are reinforced (in Fig. 1, only one (n tooth) is shown.

The tooth holder 1 is made with a hole 3 in which (B is put .3iy6 2 of (non-saturated 5th polyester resin reinforced with a stem (fiber m surrounded by elastic sheath 4 at the clamping point. Above the tooth holder 1, there is a simple or double connection with a clamp, by which

0 tightly clamped tooth. FIG. Figures 1 and 2 are presented (a simple connection of a homomix. On a tooth holder 1, a flat shackle 5 is fixed transversely to the longitudinal direction. In a hole 6 of a flat shackle 5, a flat counter-mount 7 is hung, holding the tooth 2 in place of the clamp. K; glass fiber reinforced unsaturated polyester resin is clamped by means of a screw connection

For precise direction. clamped (in a joint with a tooth clamp on the underside of the 3 P opening), the guide sleeve 9 surrounding the 5-1H is viewed; Nova Shell 4. For (Gradual increase in stiffness pr (dinners with increasing deviations (you need to reduce the active length of the fish).

Claims (4)

To reduce bending and to increase the limit (endurance (the guide sleeve 9 should have an output extension 10 corresponding to the maximum deviation of the teeth. The internal diameter of the guide sleeve | ki 9 has a size corresponding to the deviation of the three bend of the tooth, to which also the lower hole 3 is folded. Fig. 3 shows the type of crushing of two teeth 2 of an unsaturated oliester resin, glass fiber reinforced glass, which are installed on the double tooth, on the base tooth of the tooth holder 1. With this design, the double The clamp is connected, the flat earring 5 is fixed on the tooth holder 1 longitudinally on the arm; neither, and, but flat on the platform 7, covers both teeth, which are clamped with the OVIN.YY-M connection 8. This design is also suitable and for tooth holders 1, which are equipped with more than two teeth of glass fiber-reinforced unsaturated polyester resin, Fig. 5 shows a tooth of unsaturated polyester resin, arm: And with fiberglass, with a gripping gamble with a sliding sleeve 11. Tooth 2 of not fiberglass-reinforced saturated polyester resin, together with its own elastic shell 4, is inserted with a positive fit into the jaw; street 11, for a stopService, it is mounted on the tooth holder 1 with a Hummy, m. To reduce the bending stress of the teeth of the unsaturated polyester resin, the fiberglass fiberglass, at the end of the gripping sleeve 11 there is an output lash 10. In FIG. 6 shows a tooth of an unsaturated polyester resin, molded with fiberglass 2, which is pressed into an elastic molded piece 12 and held in sepx-HH.M 13 iH Bottom 14 by lugs, in the tooth holder 1. On the knit of the molded piece 12, an output extension is also provided. 10. Claim 1. Fastening of teeth in devices for treating stalked cultures, especially for teeth from jensy-saturated polyester resin reinforced with stems of fiber, which are mounted on the tooth holder, characterized in that on the tooth holder 1 is installed The union is a clamp, preferably consisting of a flat earring 5 and a flat counter-belt 7, between which a tooth of an unsaturated polyester resin reinforced with fiberglass 2 is clamped, surrounded by an elastic sheath passing through the hole 3 of the tooth holder, and that a guide bush 9 is located on the tooth holder 1, ending with an output extension 10 and a tooth enclosing with a gap. 2. The fastening of the teeth according to claim 1, from l and h that is, that on the tooth holder 1 there is a double or myogacrate connection ho.mut1I1KO.m, in which two or more teeth are clamped. 3. Fastening the teeth on pi. 1 and 2, characterized in that the gripping sleeve 11, having an output expansion 10, passing through the tooth holder 1, encloses the tooth 2 with a hermetic closure. 4. Fastening teeth in PP. -3, which is distinguished by the fact that the tooth is pressed into an elastic plastic piece 12, having an output extension 10, and the shaped etal 12 has protrusions 13 and 14, between which it is fixed in the tooth content 1. It is recognized by the invention according to the results of examination, carried out by knowledge of on the inventiveness of the German Democratic Republic. ffe./ Fg / g rj
