Does the rail pressure block affect the lock nut?

The radial locking nut of the guide rail clamp is a thinner kind of precision nuts. It is especially suitable for working conditions with limited thickness space. It mainly works on precision screw rods, medium-speed rotating shafts and precision measuring instruments.
This design does not bear the axial load acting on the thread. The hexagon socket fastening screws of this nut are evenly distributed in the radial direction of the nut body, and the top of the hexagon socket fastening screw is inlaid with locking brass with internal threads.
The axial lock nut has the same thickness and the same price as the flank lock nut. When the precision nut is locked, the thread surface will not release the axial load and the nut body will not be deformed.
Personally, it is more appropriate to choose a belly lock nut at the same price. We use a hook wrench to screw the precision nut into the outer thread of the screw rod. After tightening, in order to prevent loosening, it is axially locked.
If the assembly space is not restricted, tighten the hexagonal fastening screws on the end face evenly to tighten the taper locking brass at the front end to achieve the locking effect of the nut.
Because the locking brass will not deform, many people tend to overlook the hook-shaped wrench slot that is also uniformly distributed on the outer circle of the nut. The three uniformly distributed locking brass can also be used to adjust the other components that will be installed on the shaft. deviation.
This precision nut can still maintain precision after being disassembled many times. As the name suggests, the hexagon socket screw is designed to the non-working surface of the shaft end, but the locking brass is still uniformly distributed in the radial direction.
Then use an external hexagonal wrench to tighten the tightening screws evenly, and the guide rail pressing block tightening screw radially pushes out the locking brass and the outer thread is tightly meshed to achieve the effect of locking the bearing or other parts. The abdominal lock nut and the radial The principle of the lock nut is the same, the difference is that the hexagon socket screw and the thread of the nut body are at an angle of 30 degrees.
