AI Technical Summary
Technical Problem
Existing CNC machine tool spindle drive devices are prone to belt friction slippage and stalling under high load torque, affecting machining accuracy.
Method used
The system employs a brake belt, compensating pulley, tensioning arm, and interlocking drive mechanism. By detecting speed differences through a speed sensor, the compensating pulley and tensioning mechanism compensate for and tension the brake belt to ensure synchronization and stability during load braking transmission.
Benefits of technology
It improves the braking transmission efficiency and accuracy of the machine tool spindle, avoids friction slippage and stalling caused by belt transmission, and ensures the machining quality of the machine tool.
