Abstract

The invention relates to the field of transport engineering and provides improved manufacturability of the hinge. The hinge contains two extreme lugs 1, central lugs 2, connecting pin 3 with limiting 4 and 5 radial interchangeable rubber elements 6 mounted on it. Rubber elements 6 are fixed to the finger and inside the central lugs - the inner surfaces of all the eyes slides on the outer surfaces of the stops 4 and 5. As the stops are worn, rubber elements perceive most of the work of the hinge, thereby reducing the wear on the stoppers. 2 hp f-ly, 1 ill.

The invention relates to transporting machine building, preferably track chains with a rubber-metal joint.

The purpose of the invention is to improve the manufacturability of the hinge.

The drawing shows a rubber metal joint, a longitudinal section.

The hinge contains two extreme lugs 1, three central lugs 2, a connecting pin 3 with radial stirrs 4 and 5 on it, and e- rubber elements for the central and extreme lugs respectively. On the connecting finger, only inside the central 10

perceive themselves an increasing part of the work of the hinge, thereby reducing the wear of the limiters at the same time. In order to ensure high durability of the hinge, the rubber elements must have such elasticity that at the end of the hinge operation, the wear of the restraints is 3-5 mm. The end of operation is determined by the failure of the rubber elements due to the simultaneous impact of compressive and bending loads.

Claims (3)

Claim 1. Rubber-metal hinge of the track lugs, rubber elements of the chain are fixed, containing lugs of matching 6. The outer surface of the latter is fixed in the holes of the lugs. The outer diameter of the radial stirring stops of the rubber elements is the same in all eyes. 20 finger joints with annular rubber elements fixed on it, and limiters of radial movements of rubber elements installed inside the holes, characterized in that, in order to improve the manufacturability of the hinge, the central lugs are made with rubber elements, movement of rubber elements. The hinge works as follows. The rotation of the mating links is carried out by their rotation around the connecting pin 3. The elastic rubber elements must ensure that the limiters are already included in the operation at the initial tension of the track chain. When the links rotate, the inner surfaces of all the openings slide along the respective outer surfaces of the stops 4 and 5. At the beginning 25 finger joints with annular rubber elements fixed on it, and limiters of radial movements of rubber elements installed inside the holes, characterized in that, in order to improve the manufacturability of the hinge, the central lugs are made with rubber elements, movement of rubber elements. 2. A hinge according to claim 1, characterized in that the limiters of the radial movement of the rubber elements in the outermost eyes are made over the entire length of the eyes. 3.Sharnir on PP. 1 and 2, different the operation of the limiters perceived by the fact that, in order to reduce the strain the maximum part of the work of the hinge, the rate of wear limiters at this time the maximum. As the limiters wear, rubber elements shrink more and more. the fingers, the radial movement stops of the rubber elements are made longer than the lugs and are placed in the extreme lugs and partly in the central lugs. perceive themselves an increasing part of the work of the hinge, thereby reducing the wear of the limiters at the same time. In order to ensure high durability of the hinge, the rubber elements must have such elasticity that at the end of the hinge operation, the wear of the restraints is 3-5 mm. The end of operation is determined by the failure of the rubber elements due to the simultaneous impact of compressive and bending loads. Claim 1. Rubber-metal hinge track chain containing lugs matching chain containing lugs finger joints with annular rubber elements fixed on it, and limiters of radial movements of rubber elements installed inside the holes, characterized in that, in order to improve the manufacturability of the hinge, the central lugs are made with rubber elements, and movement of rubber elements. 2. A hinge according to claim 1, characterized in that the limiters of the radial movement of the rubber elements in the outermost eyes are made over the entire length of the eyes. 3.Sharnir on PP. 1 and 2, different in order to reduce the strain the fingers, the radial movement stops of the rubber elements are made longer than the lugs and are placed in the extreme lugs and partly in the central lugs.
