Non-contact damping device, utilization method thereof, and rotating ring with non-contact damping device

Abstract

The invention discloses a non-contact damping device. The non-contact damping device wraps the periphery of a rotating shaft through a fixed sleeve, a plurality of brake discs which are arranged up and down at intervals and are connected with the rotating shaft are arranged in the fixed sleeve, separation discs are arranged between the adjacent brake discs, permanent magnets are arranged in the separation discs, magnetic induction lines of the permanent magnets are connected into an integrated loop, a constant magnetic field is formed in the fixed sleeve, the rotating shaft rotates to drive the brake discs to rotate, and the brake discs and the permanent magnets relatively move to generate damping force for the rotating shaft. According to the non-contact damping device, damping force canbe generated without media or contact friction, abrasion of a force transfer medium is avoided, the damping effect is long-lasting and stable, and the requirement on maintenance for the damping deviceis greatly reduced; and damping force can be continuously provided for an operation mechanism, the change relationship of speed and damping force can be set according to the requirement of the operation mechanism, and damping force is automatically adjusted in real time according to speed change during the operation process of the mechanism.

Description

【Technical field】 [0001] The invention relates to a non-contact damping device, a method for using the non-contact damping device, and a rotating cup with the non-contact damping device. 【Background technique】 [0002] In the machinery industry, it is a very common phenomenon to achieve operations through the operation of mechanisms, and most operating mechanisms inevitably have the risk of "overspeed". Therefore, it is very necessary to carry out speed limiting protection on the operating mechanism, and the most common speed limiting protection measure is to set a mechanical damping device in the operating mechanism. [0003] The traditional mechanical damping device needs to pass through the medium or contact friction to generate resistance to achieve the purpose of speed limitation. However, as the number of times of use increases and the time increases, the power transmission medium will be worn out, resulting in a decrease in or even loss of the speed limiting effect, ...

AI Technical Summary

Problems solved by technology

However, as the number of times of use increases and the time increases, the power transmission medium will be worn out, resulting in a decrease in or even loss of the speed limiting effect, and regular maintenance must be carried out

[0004] In addition, the traditional mechanical damping device needs to judge the speed, and can only be triggered when the speed condition is met, and the damping force after triggering is a fixed value, which cannot be automatically adjusted in real time as the speed changes
