Definitions

  • the invention relates to a tooth cap for Construction machines with wedge-shaped to each other Work surfaces.
  • Tooth caps for construction machinery as wear parts are known in many forms.
  • a bucket, a shovel, one Excavator bucket or a chisel element truncated pyramid-shaped holder provided on the a tooth cap can be pushed on, which is why Tooth cap has a recess on the tip of the tooth has opposite side, in which the truncated pyramid element is included.
  • the Tooth cap can be fitted with suitable fasteners, for example with heavy duty pins or the like on the truncated pyramid-like element be attached.
  • Such a tooth cap has in essentially the shape of a wedge, the wedge-shaped surfaces form the work surfaces.
  • transverse ribs which are preferably additional are to be provided, but alternatively if necessary can also be provided similar effect because of the cross ribs quasi a transverse to the driving direction of the tooth cap Directed wave pattern is generated so that the protruding areas of the cross ribs the material displace the past areas between the Cross ribs, however, as free spaces in particular cohesive soils are available so that the friction forces to be applied when driving in Tooth cap are reduced, and also by open spaces formed between the transverse ribs Volume is provided, in which loosened soil or the like penetrate can. This also makes the effort when Penetration of the tooth cap in the ground or the like diminished.
  • At least one of the work surfaces transverse to the longitudinal extent between the marginal edges laterally delimiting the wedge surface is domed and several longitudinal ribs in the Middle area of the wedge surface approximately parallel to the Edge edges are formed.
  • This training ensures that the Tooth cap relatively flat towards its cutting edge is formed (relatively small wedge angle), while the tooth cap to the other end area, in the the truncated pyramid or the like is inserted, the part of the construction machine is progressive thickened.
  • This training is in combination with the preferably exclusively provided longitudinal ribs particularly advantageous and for a low-power Placing the tooth cap in the ground or the like conducive.
  • the Longitudinal ribs have such a height that they face each other the edges.
  • the Longitudinal ribs have a distance from each other that larger than the height of the ribs and smaller than that is eight times the height of the ribs.
  • the Longitudinal ribs over rounded transitions into the Pass over the wedge surface and the rib ridge line is also rounded.
  • the tooth cap as a loading tooth for example for a loading bucket or the like is used, it is provided that a Work surface with longitudinal ribs and / or transverse ribs is provided and the other work surface in essentially flat and with longitudinal grooves is provided.
  • a plurality of longitudinal grooves are formed next to one another, spaced apart from one another by approximately the groove width.
  • the grooves form a wavy line in cross section.
  • grooves are the same Number and roughly the same orientation as that Longitudinal ribs are provided.
  • Another improvement in anti-friction and power-reducing effect is achieved in that that connect the wedge-shaped work surfaces Side surfaces of the tooth cap are bulged.
  • the Tooth cap a quasi an undercut wedge-shaped training with an in Driving direction behind the free space through the Bulge created, which in turn for the Reduction of friction when entering soil or the like is beneficial.
  • the Bulging from the tip of the tooth cap to about Spout of the longitudinal ribs is provided.
  • the outlet of the longitudinal ribs is in the area provided in which the actual work tip the tooth cap into the back of the tooth cap passes over, which receives the truncated pyramid of the corresponding construction machine.
  • At least one of the work surfaces in the middle has a wedge-shaped longitudinal rib, of two converging towards the tip of the tooth cap Longitudinal ribs is formed, the one between them have flat valley and each other opposite longitudinal edges over a deep valley in pass over the working surface of the tooth cap.
  • the wedge-shaped longitudinal rib Due to the wedge-shaped longitudinal rib a additional stiffening achieved.
  • the wedge-shaped longitudinal rib when tearing and loosening of the soil or of the rock.
  • the wedge-shaped longitudinal rib when tearing and loosening of the soil or of the rock.
  • the mode of action of the longitudinal ribs is with this training as well as with the Embodiments described above, comparable to the effect of a fork with its prongs in the Working surface of the tooth cap is incorporated, whereby a corresponding loosening effect and friction-reducing effect is achieved.
  • This training is preferably advantageous for excavator teeth, gripper teeth and chisel teeth, because this scale-like arrangement of transverse ribs provides relief spaces through the undercut, so that, on the one hand, when the tooth cap is driven in, not the entire working surface of the tooth cap rests on the earth material or the like, but only that surfaces of the transverse ribs pointing towards the tip of the tooth cap, while the area forming the undercut, in particular in the case of cohesive bottoms or the like, is not in contact with the bottom, that is to say has a friction-reducing effect.
  • this space can accommodate loosened soil or rock flour, so that there is relief when driving in the tooth cap and the soil or the like is compacted to a lesser extent. It is preferably provided that a plurality of transverse ribs are provided at an even distance from one another.
  • grabs or Chisel tooth caps are provided for both Work surfaces in the same way with longitudinal and / or Cross ribs are provided.
  • Tooth cap tip is approximately rectilinear, transverse to Longitudinal extent of the tooth cap aligned Has cutting edge.
  • the tooth cap tip a rounded across the length of the Has tooth cap aligned cutting edge.
  • the tip of the tooth cap in the middle is formed to form approximately a straight chisel edge, to the curved or stepped edge areas connect that to the side surfaces of the tooth cap connect.
  • transverse ribs are slightly curved, whereby the center of the bend beyond the tip of the tooth opposite end of the tooth cap. (Cross to Axis of the dowel pin or the like).
  • This training ensures that Penetration of the tooth cap in the ground or the like loosened material transverse to the driving direction of the Tooth cap is conveyed obliquely to the rear so that this material does not condense before Tip of the tooth cap lying soil or the like leads.
  • All tooth caps have in common that they are on the Cutting edge 1 facing away from end region 2 a cavity have, for receiving a example pyramid frustum-like element which serves the corresponding construction machine, for example one Grab bucket, a load bucket or the like is arranged.
  • a truncated pyramid Element can be the tooth cap with the cavity 2 be plugged in, with holes 3 for example a fastener in the form of a Heavy Duty Pin or a Heavy Duty Sleeve can be struck to the tooth cap releasably the corresponding truncated pyramid element fasten.
  • the rear area of the tooth cap with the cavity 2 and the perforations 3 is only that Fastening area that is not the actual one Working area of the tooth cap forms.
  • the Working area of the tooth cap is in the front Area that is between the back area and the tooth tip 1 is located.
  • the work surface 4 of several longitudinal ribs 5 has.
  • the longitudinal ribs 5 start at the Cutting edge 1 of the tooth cap and end at the as Fastening area serving end area of the Tooth cap.
  • the bottom of the tooth cap, the is shown in particular in FIG essentially just trained.
  • This work surface 6 has longitudinal grooves 7 which extend from the cutting edge 1 the tooth cap to the fastening area.
  • the upper work surface 4 is transverse to Length of the tooth cap between the Wedge surface of laterally delimiting marginal edges 8 domed, with three longitudinal ribs 5 in the central region the wedge surface approximately parallel to the marginal edges 8 are trained.
  • the longitudinal ribs 5 have a such a height that it is opposite the edge 8 behind, especially from the Sectional view according to Figure 1.4 can be seen.
  • the longitudinal ribs 5 have a lateral one Distance from each other that is greater than the height of the ribs, but less than eight times the height of the Ribs.
  • the central rib 5 has the largest Height and have the adjacent longitudinal ribs 5 a lower height.
  • the longitudinal ribs go 5 via rounded transitions into the wedge surface and also into the cutting tip 1, the Ribbed ridge line is also rounded, so that in cross section gives a kind of wave profile, like 1.4 can be seen in particular.
  • the on provided on the underside of the tooth cap longitudinal grooves 7 are spaced from each other by approximately the groove width formed side by side and parallel to each other, the grooves 7 in cross section a kind Form wave profile, as again from Figure 1.4 can be seen.
  • the grooves are in this training 7 in the same number and approximately the same Orientation like the longitudinal ribs 5 is provided, however on the other wedge surface respectively Working surface 6 of the tooth cap.
  • the side surfaces 9, which are the wedge-shaped Connect work surfaces 4,6, bulged, the Bulging from the tooth cap tip 1 to about Outlet of the longitudinal ribs 5 or longitudinal grooves 7 is provided.
  • both sides of the wedge-shaped longitudinal rib 11 four such transverse ribs 13 evenly apart spaced apart.
