Description

The invention relates to mechanical engineering and can be used as a traction device in lifting machines.

The aim of the invention is to increase the reliability of the circuit by reducing the shock pulse, as well as expanding its application areas with

FIG. 1 shows a chain with a star in FIG. 2, a section of a chain;

The T Gose chain consists of steel main plates 1 and 2 connected by fingers 3 and 4. The plates are fitted with additional plates 5 and 6, connected rigidly with fingers 3. And hinged with the adjacent finger 4 "Plates 5 and 6 connected adjacent pairs of fingers; 3 and 4 alternately on one and the other side of the chain. The additional plates 5 and 6 are rigidly connected to the opposite ends of the finger 3, and 4 are hinged with the neighboring fingers 4 and fixed one relative to each other at an angle of OiCo; 90 ° due to the rigid connection with opposite ends of the finger 3. The chain pitch is defined by two cylindrical hinges 1 "and two adjacent fingers, Mi 4s, which hinge 3 is located, away from the plane on which the cylindrical axes of two additional plates 5 are located and 5 located at an angle to each other

 The chain possesses high: vibropoglozheniya because of the high vibropoglo1 of the characteristics of the papiev 3 material with a shape memory effect, for example, titanium nickelide. I

Chain link - main plates 1 and 2.1. Additional plates 5 and 6 and fingers 4 are made of steel 40 45 45, 50 and heat treated (street or normalization), v fingers 3 are made of material with the effect of aam tk form , for example, nickelide titanium. The pins 3 and 4 are connected to the plates 1 and 2 pivotally. The chain is folded so; So that between the additional plates 5 and 6, connected by a finger 3 with the effect of form, a predetermined angle is formed, and with the help of special equipment, make a rigid connection of fingers Z. with plasters 5 and 6, for example, using Welding Connection of sections of the circuit dopo: shitelnip and: plates 5 and 6 to the fingers - anddiscriminate sharn

the frame is carried out by elongated fingers 4 on the cotter pins.

Under the action of shock loads on the chain, the pivotally mounted fingers 4 transmit forces to the additional plates 5 and 6 and twist the fingers 3 rigidly fastened with them to provide shock absorption and, consequently, a decrease in the sensitivity of the circuit to shock loads.

Due to the use of fingers 3 of a material with a memory effect of shape, vibration characteristics are improved by vibration absorption

During the impact of the shock load, the angle between the additional 1 and plates varies. To bring the circuit back to its original state, it is sufficient to subject it to a relatively small heating to the temperature range of the reverse martensitic transformation.

The chain can also be used in the form of a freight body, creating a pull force without an additional source of mechanical energy. In this case, the working form of the chain is its linear state. After heating, as a result of finger crossing 3, there is a change in the angle between the adjacent links, the total length of the chain decreases and a significant amount of compression occurs: its longitudinal force. Such a chain can be used instead of cargo winches, jacks and.
