Friction-type damper device

Abstract

Provided is a friction-type damper device. The friction-type damper device mainly comprises a cover plate, an outer shell, a transfer element, a friction head, a friction disc, two bearings, a spring, a telescopic shaft and a rotating shaft. The rotating shaft and the cover plate are fixed onto connecting rods on the two sides of a joint capable of providing resisting moment correspondingly, the rotating shaft is fixedly connected with one connecting rod, and the cover plate is fixedly connected with the other connecting rod; the cover plate and the friction disc are oppositely arranged and fixedly connected together through the outer shell; the rotating shaft penetrates through a circular hole in the center of the transfer element and is fixedly connected with the transfer element, and the rotating shaft and the transfer element are together arranged between the cover plate and the friction disc; the telescopic shaft penetrates through the portion, around the rotating shaft, of the transfer element, the friction head is arranged at the top of the telescopic shaft, and the friction head abuts against the friction disc; and the rotating shaft is connected with the cover plate through one bearing, and the other end of the rotating shaft is connected with the outer shell through the other bearing located at the center of the friction disc. According to the friction-type damper device, the resisting moment of the damper has nothing to do with the rotating speed or the external force and is only related to the absolute rotation angle where the device is located, and the blank of the friction-type damper is filled in.

Description

technical field [0001] The invention relates to a friction damper device, in particular to a friction damper whose resistance moment is related to the rotation angle. Background technique [0002] Space suits are personal airtight equipment that guarantee the life activities and working ability of astronauts. They can protect the human body from environmental factors such as vacuum, high and low temperature, solar radiation, and micro meteors in space. They are key equipment for astronauts to survive. One of the three major technologies in the field of extraterrestrial survival support for manned spaceflight. With the development of manned spaceflight science and technology, the activities of astronauts out of the cabin are becoming more and more frequent, and the time for activities outside the cabin is getting longer and longer. The flexibility and fatigue of astronauts in extravehicular activities are the key to restricting manned space activities. One of technology and ...

AI Technical Summary

Problems solved by technology

The disadvantage is that there is a certain degree of wear and noise, and the resistance torque of the existing friction damper can only be adjusted by adjusting the positive pressure of the brake pad. There is no friction damper whose resistance torque changes with the rotation angle of the device, which cannot be applied to this application. Related Background of the Invention
