Problems solved by technology

In terms of safety and stability, there are mainly problems of wear and damage of components due to impact. Among them, the damage of components is mainly caused by metal materials reaching the fatigue limit strength due to impact or suffering excessive instantaneous impact force and unreasonable force.

specific Embodiment approach 2

[0039] On the basis of Embodiment 1, such as Figure 10 As shown, the inclination directions of the tapered surfaces 11 of the two friction rings are all inclined to the inside, the width and depth of the U-shaped opening 15 of the middle friction disc 13 are larger than the U-shaped opening of the friction rings, and the gap between the two friction rings is greater than that of the middle friction disc. thickness, the middle friction disc can slide a certain distance along the axial direction of the pin between the two friction rings.

[0040] Such as Figure 9 As shown, the edge of the partition 14 is also provided with a U-shaped opening, that is, the partition at this time has the same shape and material as the middle friction disc 13, and the aforementioned pin and U-shaped opening are also used to indirectly connect the partition to the inner circular surface of the box. Fixed assembly, cannot rotate. The thickness of the inside centrifugal body 16 is greater than the...

Abstract

A conical surface friction reinforcement type descent control device damping device relates to the field of high-altitude lifesaving descent control devices, and is mainly characterized in that more than two sets of centrifugal bodies are respectively in friction contact with conical surfaces of corresponding friction rings, and the positive pressure between the centrifugal bodies and the conical surfaces is greater than the centrifugal force of the centrifugal bodies; the axial component force of the conical surface to the centrifugal body increases side friction force between the centrifugal body and the middle friction disc or the partition plate. When the bevel angles of the conical surfaces of the friction rings are in the same direction, axial component force borne by one set of centrifugal bodies can be transmitted to the other set of centrifugal bodies through the middle friction disc, so that the side face friction force of the other set of centrifugal bodies is further increased, namely the total friction force is amplified, the damping effect and the safety stability are remarkably enhanced, the manufacturing cost is low, and the service life is long. In addition, starting is not affected, heat generated by friction is generated on multiple layers, and the phenomenon of local overheating can be effectively reduced.

Description

technical field [0001] The invention relates to a high-altitude lifesaving slow-descent device, in particular to a damping device for a cone-surface friction booster slow-descent device. Background technique [0002] The high-altitude lifesaving slow-descent device in the prior art is mainly divided into two types, one is the friction type, that is, the rotational speed is limited by the friction force between the high-speed rotating centrifuge and the inner circular surface of the box body, so as to achieve a uniform slow-down Purpose. Its biggest advantages are mainly reflected in the following two aspects, one is simple structure and low manufacturing cost; the other is stable force, no impact force, and less prone to accidental damage. There are two main problems. On the one hand, the friction coefficient between the two metal materials is generally small. After the friction generates heat, the properties of the metal surface layer of the friction material change, and t...
