High-speed rotary shaft brake

Abstract

The invention discloses a high-speed rotary shaft brake. The high-speed rotary shaft brake comprises a brake drum arranged on a rotary shaft in a sleeving mode. The rotary shaft and the brake drum canrotate relatively. A centrifugal mechanism is arranged in the brake drum and comprises a guiding rod mounting ring, a plurality of guiding rods and a plurality of centrifugal blocks. The side wall ofthe guiding rod mounting ring can be provided with a plurality of guiding rod mounting holes formed along the periphery of the guiding rod mounting ring. One end of each guiding rod is inserted intothe corresponding guiding rod mounting hole. The guiding rods are arranged around the guiding rod mounting ring. Each guiding rod is slidably provided with the corresponding centrifugal block and a reset spring in a sleeving mode. The reset springs are located between the centrifugal blocks and the guiding rod mounting ring. One end of each reset spring is connected with the side wall of the guiding rod mounting ring, and the other end of each reset spring is connected with the bottom of the corresponding centrifugal block. The guiding rod mounting ring is fixedly arranged on the rotary shaftin a sleeving mode. Electromagnets are used as the centrifugal blocks. Each electromagnet is connected with a controller through an electromagnet control module. A rotary shaft rotation speed detection sensor is further connected with the controller. Through the high-speed rotary shaft brake, the rotary shaft can be automatically braked at a high rotation speed.

Description

technical field [0001] The invention relates to the field of braking, in particular to a high-speed rotary shaft brake. Background technique [0002] During the rotating process of the rotating shaft, the following working conditions exist: when the rotating shaft rotates at a low speed, the rotating shaft rotates normally; when the rotating shaft rotates at a high speed, the rotating shaft stops rotating. [0003] Under normal circumstances, the braking of the rotating shaft is to manually operate the brake mechanism to lock the rotating shaft and stop the rotating shaft. Human operation will cause the operator to respond untimely, and then it is too late to brake the rotating shaft; at the same time, human operation will also cause Misuse. Contents of the invention [0004] The purpose of the present invention is to provide a high-speed rotating shaft brake, which can automatically brake the rotating shaft at a relatively high speed, in order to solve the above-mentione...
