Further, the square pin is provided with a square pin counter bore, and a sealing ring is arranged in the square pin counter bore.
Further, the ratchet wheel is provided with a lubrication hole and a lubrication groove in the matching range of the ratchet wheel shaft and the square pin hole, and the lubrication hole and the lubrication groove are communicated with the ratchet wheel cavity.
Further, the length of the ratchet cavity, the length of the protective tube cavity and the length of the protective tube cover are larger than the length of the compensating thread on the brake pull rod.
The action principle of the invention is that the brake pull rod is fixed and does not rotate when the brake works, the ratchet wheel component is limited by the structure and the assembly relation after being assembled, and the ratchet wheel rotation is only controlled by the deflector rod component, thus effectively avoiding the influence of the vibration of the equipment where the brake is positioned and the brake, further ensuring the operation accuracy of the ratchet wheel component and avoiding the generation of the overcompensation problem. When the ratchet wheel component and the deflector rod component are installed on a brake and put into use, the deflector rod of the deflector rod component drives the ratchet wheel to rotate along with the automatic compensation, the external thread of the brake pull rod gradually stretches into the ratchet wheel cavity, the volume of the ratchet wheel cavity is gradually reduced while the compensation action is completed, the lubricating grease added in the ratchet wheel cavity is extruded into the matching surfaces of the ratchet wheel shaft and the square pin hole through a lubricating hole and a lubricating groove, the lubrication of a rotating pair formed by the ratchet wheel shaft and the square pin hole is completed, and the lubricating grease is prevented from losing through a sealing ring in a square pin counter bore. When the brake pad is worn and needs to be replaced, the lubricating grease is added in the cavity again.

The invention fixes the brake pull rod, and simultaneously utilizes the mutual restriction and good lubrication of all parts of the ratchet wheel assembly, thereby effectively avoiding the influence of vibration on the automatic compensation device, eliminating the problem of over compensation and ensuring the long-term stable operation of the automatic compensation device.
2. And more importantly, when the brake mechanism is used for running to automatically compensate, the lubricating grease is continuously added to the matching surface of the ratchet shaft and the square pin hole for a long time by using the compensation action, so that the ratchet is ensured to run flexibly, and the ratchet is prevented from being blocked due to rust and other reasons.
3. The brake pull rod compensation screw thread is arranged in the protective tube, lubricating grease is added in the cavity of the protective tube, external dust can be prevented from adhering to the brake pull rod compensation screw thread while flexible operation of the compensation screw thread is ensured, and water, dust, corrosive gas and the like are prevented from rusting the brake pull rod compensation screw thread, so that the situation that compensation failure is caused by choking, clamping and the like is avoided.
4. The structural treatment of the ratchet wheel component not only well meets the requirements of the brake on various environmental conditions, geometric dimensions, installation dimensions and the like of the compensation mechanism, but also can be well matched with a poking rod component (application number: 201510725151.8) of a ratchet wheel type compensation device of an industrial brake, thereby completely solving the problem of automatic compensation of the industrial brake.
