Where does the brake act on inertia?

For mechanical equipment, when it is required to stop running, it needs to use the brake to brake, but we know that after braking, due to inertia reasons, the mechanical equipment is still running continuously, but the speed is not as fast as before. So where does the brake act on inertia?

The brake is mainly used for the walking brake of the door crane. When the motor starts, the interaction between the inertial force of the load and the torque of the motor is used to make the relative rotation between the concave and convex helical surfaces, and the axial displacement is generated to open the friction pair to release the brake, which is limited by the limit device. Open the distance. When the motor is powered off, the force between the concave and convex helical surfaces disappears, and the spring energy is released to make the brake pair fit and generate braking.

It is both a brake and a coupling, featuring two-way braking and dynamic wind protection. Dynamic wind protection means that in the case of downwind walking, when the gust of wind reaches the driving force of the motor, the force between the concave and convex helical surfaces will disappear, and the spring will be released to instantly brake and open, and the driver will feel unstable, prompting the driver to stop. After stopping, the safety is ensured by the large braking force. Two-step braking inertia brake has the characteristics of small walking braking torque and large braking torque after stopping, which is generated by its structural characteristics.

Before the motor stops, the braking torque is used to brake the motor and the load. The braking torque is divided into two parts, one part is used to brake the motor, and the other part is used to brake the load. An axial reaction force will be generated between the braking helical surfaces of the motor to offset the pressure of some springs on the brake disc. After stopping, the braking force is fully loaded on the load, so the braking torque is large.
