Abstract

This invention relates to a transport engineering industry and provides increased durability by reducing specific pressures in the contact zone. Link 1 and 2 are connected by a round finger 3 and a crescent cross section 4. The jumper is set to the full width of the link, whereby the length of the contact line between the finger 3 and the concave surface 7 of the jumper 4 is equal to the width of the link, the length of the contact line between the oval hole 6 and the convex surface of the jumper 4 is approximately half the width of the link. All eyes are closed. When one link is rotated relative to another at a certain angle, the concave surface of the web rolls over the surface of the finger. 2 Il.

FIELD OF THE INVENTION The invention relates to a transport engineering, primarily tracked vehicles. j The purpose of the invention is to increase the constancy by reducing the specific pressures in the contact zone. : FIG. 1 shows a part of a girder chain, top view; FIG. 2 is a section A-A in FIG. 1,

Link 1 and 2 are connected by a round finger 3 and a crescent cross-piece 4 3. In the eyelets on one side of the link, the aperture 5 is larger in diameter than the finger, on the other hand oval apertures 6, covering the finger and web, and all eyes are closed. The length of the contact line between the finger 3 and the concave surface 7 of the jumper 4 is equal to the width of the link, and the length of the contact line between the oval hole 6 and the upper surface of the jumper 4 is approximately half the width of the link. Consequently, the specific pressures in the contact zones of the proposed technical solution are significantly lower than those of the prototype.

The connection works as follows.

When one link is rotated relative to another at some angle, the surface 7 of lintel 4 perpendicular

It rolls along the surface of the finger, and the web 4 turns inside the oval eyelet 6 of the adjacent link.

The bridge and the finger are installed in the lugs when the track is not tightened freely, but after tensioning the caterpillar under the action of frictional forces, the bridge is rigidly connected to the lugs of link 1, and the finger to the lugs of link 2.

Claims (1)

Invention Formula The caterpillar chain, containing links connected by fingers, in each eye of one of which holes are made with a diameter greater than the diameter of the finger, and a bridge with a convex outer and concave is placed on the slider. The inner surfaces interacting with the adjacent link and the finger, respectively, in the eyes of the second link are filled with a diameter equal to the diameter of the finger, characterized in that, in order to increase durability by reducing the specific pressures of the contact zone 9, the holes in the second link are filled with oval , and all the lugs are closed, while the jumper is made to the full width of the link and is located in all the eyes of the adjacent links.
