(57) Abstract:

The site of the tooth is intended for use in the development of soil excavation machines. The site of the tooth includes a tooth tip with protruding ears, mating with corresponding grooves in the adapter, to transfer forces from the top of the adapter. In the proposed implementation the top of a tooth includes two opposite loops, each of which has two opposite surfaces of the edges that are angled relative to each other. Two opposite ear tooth tip mate with two corresponding opposite grooves made in the adapter. Two opposite groove in the adapter similarly have two opposite surfaces of the edges that are angled relative to each other and coming into contact with the two opposite surfaces of two opposite edges of the ears. This design prevents shifting toward the outside of two opposite lugs relative to the adapter. 3 S. and 7 C.p. f-crystals, 4 Il.

The present invention relates generally to the node of the tooth, as well as to the top of the tooth and the adapter.

Many famous sites of the teeth consist of the top of the tooth and is transient and tops. Although the ears help to regulate the force applied to the top, through the transfer of these efforts on the adapter, the different types of loads have a tendency to bend the ears of the vertices in the outer direction, thus causing damage to the ears (see, for example, US And 3708895, US, A, 4231173).

The present invention is intended to solve one or more of the problems listed above.

One aspect of the present invention is to offer a host of tooth comprising a tooth tip, the adapter and the retention mechanism. Through the center of the top and center of the adapter passes a longitudinal plane. In the rear part of the top of the tooth is made of two coaxial holes and cavity.

From the inlet cavity back are two ears, and each ear has two opposite side surfaces and two opposite edges. The surface edges of each of the ears are angled relative to each other, so that the width of the side surface, are the accessories to the longitudinal plane exceeds the width of the opposite side surface.

The adapter has a front end which is designed to align with the cavity in the top of a tooth and provided with a hole for stepto the ENES two opposite groove. Each groove of the two grooves has a side surface oriented essentially parallel to the longitudinal plane and two opposite surfaces of the edges.

The surface edges are angled to each other, so that the surface edges are farthest away from each other at the intersection of the surfaces of the edges with the side surface. The surface edges of the two ears after Assembly are in close contact with the surfaces of the edges of the respective grooves of the adapter.

Another aspect of the present invention is to offer the top of the tooth, which is designed for connection with the adapter. The top includes two coaxial holes, the cavity located between the corresponding holes, two holes and a longitudinal plane between them. Near the inlet of the cavity back are two loops. Each of the lugs has two opposite side surfaces and two opposite edges. The surface edges of each of the ears are angled relative to each other, so that the width of the side surface located closest to the longitudinal plane exceeds the width of the opposite side surface.

According to another aspect of this is Near the front end of the adapter is made of two opposite groove. The adapter described longitudinal plane, oriented longitudinally and passing between the respective grooves of the two opposite grooves.

Each groove of the two grooves has a side surface oriented parallel to the longitudinal plane and two opposite surfaces of the edges. The surface edges are angled to each other, so that the surface edges are farthest away from each other at the intersection of the surfaces of the edges with the side surface.

The present invention provides a node of a tooth, consisting of a tooth tip with two opposing lugs located at an angle to each other surfaces of the edges and adapter with the slots with the corresponding surfaces of the edges, in which, after Assembly, the ears are aligned with the corresponding slots of the adapter.

In the process of applying the trend of the respective lugs to bend toward the outside relative to the adapter causes the beveled contact surfaces of the edges of the lugs with the corresponding surfaces of the edges of the slots, which limits further movement of the ears of the vertices in the outer direction.

In Fig. 1 schematically shows the site of the tooth with a picture of all the item is; in Fig. 3 shows a top view and partly in section; Fig. 4 shows the image in the incision made along the line 4-4 in Fig. 2.

In the drawings shows the node 10 of the tooth. The node 10 of the tooth consists of vertices, 12 tooth, adapter 14 and the mechanism 16 is mounted. The top 12 has a front end 18, which should affect the material being processed, and the rear end 20 that interconnects the top 12 with the adapter 14. In the rear end 20 of the top 12 performed a cavity 24, which extends from the rear end of the top 12 inwards in the direction of the front end 18.

In the rear end 20 of the top 12 performed two aligned holes 26, 28 that intersect with the cavity 24. Through the top 12 passes a longitudinal plane 30, which runs from the front end of the top to its rear end through two aligned holes 26, 28. The top 12 has two opposite lugs 32, 34, leaning back near the inlet of the cavity 24 and placed on opposite sides of the longitudinal plane 30.

Every ear of two opposite lugs 32, 34 has two opposite side surfaces 36, 38 and two opposite surfaces of the edges 40, 42, intersecting with two side surfaces 36, 38. Each poweraqua surface 38 of the two opposite side surfaces 36, 38, located closer to the longitudinal plane 30, wider than the other side surface 36.

In addition, each surface edges of the two opposite surfaces of the edges 40, 42 is located relative to a line perpendicular to the longitudinal plane 30 at an angle in the range from 4 to 15o. Preferably, each surface edges of the two opposite surfaces of the edges 40, 42 were in relation to a line perpendicular to the longitudinal plane 30 at an angle in the range from 6 to 10o.

The adapter 14 has a front portion 46 with holes 48 for the pin and the longitudinal plane 50, held in common through the center hole 48 for the pin. As shown in Fig. 3, the longitudinal plane 50 of the adapter 14 coincides with the longitudinal plane 30 of the top 12 when the top 12 is installed on the adapter 14. In front of the 46 completed the groove 52 to the clamp, offset holes 48 to the pin 48 and perpendicular both to the longitudinal plane 50, and the axis of the hole 48 for the pin.

The groove 52 to latch intersects with the hole 48 for the pin. The adapter 14 is made of two opposite groove 54, 56, respectively, one each on opposite sides of the longitudinal plosko intravenou generally parallel to and along the longitudinal plane 50.

In addition, each slot of the two slots 54, 56 also has two opposite surfaces of the edges 60, 62, intersecting with the side surface 58. Each surface edges of two opposite surfaces of the edges 60, 62 is relative to a line perpendicular to the longitudinal plane 50, at an angle in the range from 4 to 15oand more preferably in the range of from 6 to 10o.

The mechanism 16 attachment includes a pin 66 and the leaf spring 68. The plate spring 68 is in engagement with the pin 66 and is applied to the fixing pin 66 in position.

It is recognized that there is a possibility of application of different forms of node tooth without derogating from the substance of the invention. For example, it is recognized that two opposite grooves 54, 56 of the adapter 14 can be part of the front portion 46. In addition, although States that two opposing loops 32, 34 have the surface edges 40, 42 that are angled to each other, similarly recognized that two opposite loops 32, 34 may have a stepped edge and two opposite grooves 54, 56 of the adapter 14 can similarly have corresponding stepped surface for receiving a respective pair of protivopoloznom 68 mechanism 16 engages. During Assembly, the two opposing loops 32, 34 move in the corresponding two opposite grooves 54, 56.

In the process, the forces acting on the front end 18 of the top 12, all together are passed to the adapter 14 through the pin 66, the front portion 46 and due to the interaction between the opposite lugs 32, 34 and the respective pair of opposite grooves 54, 56.

If under the influence of effort applied to the front end 18 of the top 12, any loops from two opposite lugs 32, 34 will start offset in the outer of napravlenii relative to the slot, its movement will be limited. The movement in the outer direction is limited to one of two opposite surfaces of the edges 40, 42 of the two opposite lugs 32, 34 that are in contact with corresponding surfaces of the edges of two opposite surfaces of the edges 60, 62 of the two opposite grooves 54, 56.

As soon as the beveled surface of one of the opposite surfaces of the edges of the two surfaces of the edges 40, 42 abuts the corresponding surface of the edges of two opposite surfaces of the edges 60, 62 of the two opposite grooves 54, 56, the movement in the outer direction will stop. Further tendencies ear force directed in the inner direction.

This is a result of the sliding surface of the one edge loops along the mating surface of the corresponding surface of the corresponding edges of the groove. Regardless of the direction in which the applied force to the top 12, any tendency to shift toward the outside of any loops from two opposite lugs 32, 34 is suppressed to a considerable extent, thereby limiting the tendency of breakage of any of the two opposite lugs under the influence of such efforts.

Considering all the above, it should be clear that the design which is the subject of the present invention, allows to obtain the node 10 of a tooth, comprising two opposite loops 32, 34 with opposite beveled surfaces of the edges 40, 42, paired with beveled surfaces of the edges of two opposite surfaces of the edges 60, 62 of the two opposite grooves 54, 56.

Such mutual position allows movement of the respective ears of the two opposite lugs 32, 34 in the respective grooves of the two opposite grooves 54, 56, but does not allow free movement of the respective ears of the two opposite lugs 32, 34 in the outer uplnosti any further tendency of the respective lugs of the tooth tip to tagnuts in the outer direction leads to efforts acting on the corresponding tabs in the inner direction, which is due to the fact that the beveled surfaces of the edges of the ears peaks begin to slide in the inner direction relative to the beveled surfaces of the edges of the adapter.

As a result of this working force applied to the top, more efficiently and effectively transmitted to the adapter without any tendency to bending of the ears toward the outside in such extent that would be possible breakdown.

Other aspects, objectives and advantages of the present invention can be found in the study of the drawings, description and appended claims.
