Abstract
The invention provides iron teeth for a rubber track, and relates to the technical field of the structure of iron teeth of a rubber track. In the structure of the iron teeth, a left wing part and a right wing part are integrally arranged on two sides of a gap bridge respectively; a left guide bulge protruding from the front side of the gap bridge is arranged between the gap bridge and the left wing part, and a right guide bulge protruded from the front side of the gap bridge is arranged between the gap bridge and the right wing part. The iron teeth for the rubber track are characterized in that: a left bump and a right bump which protrude from back sides of the left and the right wing parts are respectively arranged on the outer end of the left wing part and the outer end of the right wing part. A steel wire is limited by the left and the right bumps to transversely move out of the edge of iron teeth in the longitudinal direction, and the problem of concentrated stress between the edge of the iron teeth and rubber is avoided due to the cambered surfaces of the left and the right bumps, so that damage of patterned rubber at left and right ends of the rubber track, caused by extrusion of a barrier when the rubber track runs, is reduced, and the service life of the rubber track is prolonged.
Description
Technical field
The present invention relates to the production technical field for the rubber belt track that industrial vehicle adopted of representative such as portable vehicle for construction, agriculture and forestry machinery, transport trolley, particularly the technical field of structures of the iron teeth in it.
Background technology
In the rubber belt track of the circulation banding pattern that forms by rubber elastomer, be embedded with steel wire, and the certain distance of spacing is embedded with iron teeth as circumferential enhancing skeleton.At the rubber belt track edge, the left and right alar part rounded at the edge of general iron teeth is smaller, make iron teeth sharper, when the rubber belt track edge presses obstacle, hard obstacle and iron teeth alar part edge form great shear forces, this shearing force will cause track edges to destroy, and make the crawler belt life-span shorten.
In addition, when crawler belt is produced, steel wire be placed in advance iron teeth above because the device of steel wire side travel without limits, when high temperature vulcanized, the rubber of temperature flowing can drive steel wire and move along the iron teeth length direction, steel wire will move to outside the iron teeth.Steel wire does not have the restriction of iron teeth, and in the middle of the crawler belt operation, steel wire is stressed, is easy to extract out from rubber, causes crawler belt to scrap.
Summary of the invention
The present invention seeks to propose in order to overcome the problems referred to above a kind of when preventing that crawler belt from producing steel wire be shifted, prevent that crawler belt is by the rubber belt track iron teeth of hard obstacle shearing.
The present invention includes gap bridge, disjunctor is provided with portion of left wing and right wing part respectively in the both sides of passing a bridge, between gap bridge and portion of left wing, be provided with and protrude from the positive left guide protrusions of passing a bridge, between gap bridge and right wing part, be provided with and protrude from the positive right guide protrusions of passing a bridge, be respectively equipped with left projection and the right projection that protrudes from the portion of left wing and the right wing part back side in the outer end of portion of left wing and right wing part.
The present invention can prevent effectively that at the left projection and the right projection at the portion of left wing and the right wing part back side phenomenon that steel wire moves laterally to outside the iron teeth lengthwise edge in the crawler belt production process from taking place, the tip of having improved portion of former left wing and right wing part outer end simultaneously is subject to the phenomenon generation that hard thing is sheared, thus the service life of having improved whole crawler belt.
In addition, left projection of the present invention and right projection are arcwall face along the outside of portion of left wing and right wing part length direction.Can disperse the pressure that is subjected between iron teeth edge and the track edges rubber, thus the destruction that the decorative pattern face rubber that has reduced the left and right end of rubber belt track is caused by the obstacle extruding when moving because of crawler belt.
Description of drawings:
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the rear perspective view of Fig. 1.
Among the figure: 1-passes a bridge, portion of 2-left wing, 3-right wing part, 4-left side guide protrusions, the right guide protrusions of 5-, 6-left side projection, the right projection of 7-.
The specific embodiment
As shown in Figure 1, 2, pass a bridge 1 both sides respectively disjunctor portion of left wing 2 and right wing part 3 are set, between gap bridge 1 and portion of left wing 2, be provided with the left guide protrusions 4 that protrudes from 1 front of passing a bridge, between gap bridge 1 and right wing part 3, be provided with the right guide protrusions 5 that protrudes from 1 front of passing a bridge.
Be provided with the left projection 6 that protrudes from portion of left wing 2 back sides in the outer end of portion of left wing 2.
Be provided with the right projection 7 that protrudes from right wing part 3 back sides in the outer end of right wing part 3.
Claims (2)
1. rubber belt track iron teeth, comprise gap bridge, disjunctor is provided with portion of left wing and right wing part respectively in the both sides of passing a bridge, between gap bridge and portion of left wing, be provided with and protrude from the positive left guide protrusions of passing a bridge, pass a bridge and right wing part between be provided with and protrude from the positive right guide protrusions of passing a bridge, it is characterized in that being respectively equipped with left projection and the right projection that protrudes from the portion of left wing and the right wing part back side in the outer end of portion of left wing and right wing part.
2. according to the described rubber belt track iron teeth of claim 1, it is characterized in that described left projection and right projection are arcwall face along the outside of portion of left wing and right wing part length direction.
