Abstract
The utility model discloses a disconnected type thrust wheel is prevented in three holes of excavator, including thrust wheel body, counter roll, the middle part of thrust wheel body is equipped with the centre bore, the middle part of counter roll is connected in the centre bore through the copper sheathing, both ends are located the outside of thrust wheel body about the counter roll, both ends are connected with the side cap respectively about the counter roll, the side cap is located the both sides of thrust wheel body, both ends are equipped with an installation screw hole respectively about the counter roll, be equipped with two screw holes on the side cap, the central line of installation screw hole and the central line of screw hole are on the coplanar. The utility model provides the high bearing capacity and the anti fatigue strength of product makes the life of whole excavator thrust wheel effectively improved.
Description
Technical field
The utility model relates to excavating machine field, refers more particularly to a kind of three anti-breaking type caterpillar wheels in hole of excavating machine.
Background technology
Traxcavator due to whole fuselage be all iron structure, cause fuselage weight general all heavier, and caterpillar wheel mainly supports the weight of complete machine, and by weight distribution on caterpillar block, when excavating machine is turned, caterpillar wheel needs clamping crawler belt and drives it to turn to, and such caterpillar wheel not only will bear the pressure from lathe bed, but also will bear the moment of torsion because main frame turns to generation powerful.
Current existing caterpillar wheel is all that fulcrum two ends are respectively drilled with an installation screw hole, when excavating machine when turning to because caterpillar wheel bears larger moment of torsion, single to install the screw power of bearing larger, easily cause fracture by fatigue, and the screw of fracture is also difficult to take out, to bringing much inconvenience in use procedure, a serious even whole excavating machine cannot normally work, and schedule delays causes many not unnecessary losses.
Utility model content
The three anti-breaking type caterpillar wheels in hole of the excavating machine that the purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of structure simple, practical.
The utility model realizes in the following way:
The three anti-breaking type caterpillar wheels in hole of excavating machine, it is characterized in that: comprise caterpillar wheel body 1, fulcrum 2, the middle part of described caterpillar wheel body 1 is provided with centre hole 11; The middle part of described fulcrum 2 is connected in centre hole 11 by copper sheathing 3, and the two ends, left and right of described fulcrum 2 are positioned at the outside of caterpillar wheel body 1; The two ends, left and right of described fulcrum 2 are connected to side cover 4, and described side cover 4 is positioned at the both sides of caterpillar wheel body 1; The two ends, left and right of described fulcrum 2 are respectively equipped with an installation screw hole 21; Described side cover 4 is provided with two screw holes 41; The line of centers of described installation screw hole 21 and the line of centers of screw hole 41 are at grade.
Described side cover 4 is provided with O type circle 5 with the junction of fulcrum 2.
Float grease seal 6 is provided with between described side cover 4 and caterpillar wheel body 1.
The beneficial effects of the utility model are: side cover is provided with two screw holes, and fulcrum two ends respectively have one to install screw hole, and center, hole at grade; Excavating machine operationally its weight is shared uniformly by each installation screw of each caterpillar wheel both sides, decrease the stressed of every screw, the load-carrying capacity of the product improved and fatigue resistance, make effectively improve the service life of whole thrust wheel of digging machine.

Fig. 2 the utility model structure side view.
Detailed description of the invention
Now by reference to the accompanying drawings, the utility model detailed description of the invention is described in detail in detail:
As shown in Figure 1 and Figure 2, a kind of three anti-breaking type caterpillar wheels in hole of excavating machine, comprise caterpillar wheel body 1, fulcrum 2, the middle part of caterpillar wheel body 1 is provided with centre hole 11; The middle part of fulcrum 2 is connected in centre hole 11 by copper sheathing 3, and the two ends, left and right of fulcrum 2 are positioned at the outside of caterpillar wheel body 1; The two ends, left and right of fulcrum 2 are connected to side cover 4, and side cover 4 is positioned at the both sides of caterpillar wheel body 1; The two ends, left and right of fulcrum 2 are respectively equipped with an installation screw hole 21; Side cover 4 is provided with two screw holes 41; The line of centers of installation screw hole 21 and the line of centers of screw hole 41 are at grade.
The utility model side cover 4 is provided with O type circle 5 with the junction of fulcrum 2.
Float grease seal 6 is provided with between the utility model side cover 4 and caterpillar wheel body 1.
The utility model side cover 4 is provided with oil hole, for caterpillar wheel body 1 charging-up lubricant oil.
The utility model has side cover 4 to be provided with two screw holes 41, and fulcrum 2 two ends respectively have one to install screw hole 21, and the line of centers installing the line of centers of screw hole 21 and screw hole 41 at grade; Excavating machine operationally its weight is shared uniformly by each installation screw of each caterpillar wheel both sides, decrease the stressed of every screw, the load-carrying capacity of the product improved and fatigue resistance, make effectively improve the service life of whole thrust wheel of digging machine.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
