What to Do When Brake Torque is Insufficient?
1 Answers
Here are the adjustment methods for insufficient brake torque: 1. Tighten the locking nut, then rotate the compression nut clockwise to compress the spring until the distance L3045mm is achieved. 2. Press the brake push rod with one hand, and use the other hand to rotate the push rod bolt so that the gap between it and the brake push rod is between 11.5mm. Adjust the other side using the same method. 3. Connect the power supply as required and open the brake to allow the brake wheel to rotate freely. 4. Operate the traction machine in both forward and reverse directions, then momentarily activate the brake switch. Observe the inverter's current value during the braking moment to see if the braking current is twice the rated current, and adjust the compression nut accordingly based on the actual value. 5. After adjusting the torque, tighten the locking nuts on both sides. 6. With the brake open and the traction machine running, slowly rotate the push rod bolt counterclockwise while carefully listening until the brake lining lightly touches the brake wheel. Then, slowly rotate the push rod bolt clockwise by approximately 90-120 degrees and tighten the push rod locking nut.
