Problems solved by technology
[0002] At present, transmission mechanisms are installed in large-scale mechanical institutions, and for some special places, power maintenance is required. Once a power failure occurs, the transmission mechanism may be reversed, and the harm caused by the reversal is uncertain. , so some methods are to increase emergency power consumption, but once the power components are damaged, the reverse phenomenon will really occur, so its potential safety hazard is relatively large

The invention discloses a power failure brake device for a transmission mechanism. The device comprises a main hollow shell; a bottom mounting base forming an integral structure with the main hollow shell is arranged at the bottom of the main hollow shell; a bolt hole is formed in the bottom mounting base; a current controller is mounted on the side surface of the main hollow shell; and an iron core is mounted in the center of the bottom of the main hollow shell. A power use mechanism and a power supply for a driving motor are positioned at the same part; when the driving motor loses power, the device can be timely started under the effect of a spiral spring; a limiting function among the parts is used for timely braking the transmission mechanism in a work stopping state to prevent the harm phenomenon caused by the reverse rotating phenomenon; in addition, the device is provided with a permanent magnet driven mechanism for cooperating with an electromagnetic mechanism without influencing normal work of the transmission mechanism under the electrifying condition; and in addition, the device is provided with a transmission shaft clamping mechanism for tightly clamping a transmissionshaft to achieve a synchronous rotating function.
Description
Technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a power-off braking device for a transmission mechanism. Background technique [0002] At present, transmission mechanisms are set up in large mechanical mechanisms. For some special places, power is required to maintain. Once a power outage occurs, it is likely to cause the transmission mechanism to reverse. The harm caused by the reverse is uncertain. Therefore, some methods are to increase emergency power consumption, but once the power components are damaged, the reverse phenomenon will really occur, so the potential safety hazards are greater. Summary of the invention [0003] The purpose of the present invention is to provide a power-off braking device for a transmission mechanism to solve the problems raised in the background art. [0004] In order to achieve the above objective, the present invention provides the following technical solution: a power-off braking ...
