AI Technical Summary
The existing two-way locking expansion sleeve is prone to shaking when fixed with bolts, which can lead to it falling off, reducing its stability and the high-precision transmission effect of the equipment.
It adopts a hydraulic high-precision bidirectional locking expansion sleeve design. Through the combination of fixing bolts, limit plate, ball bearings and tensioning mechanism, it can achieve precise adjustment of the locking degree and reduce friction between components. Combined with the linkage of screw and hook, it can ensure flexible adjustment of locking force.
It improves the stability and transmission accuracy of the equipment, reduces vibration and noise, adapts to equipment requirements with different torque ranges and installation sizes, expands application scenarios, and reduces maintenance costs.
