NF series Backstop
|
|
It is an anti-reverse device suitable for high-speed operation. The NF-type backstop has several shaped blocks distributed in the raceway formed by the inner and outer rings. When the inner ring is running forward, it drives the shaped blocks to rotate together. When the speed is within a certain range, the shaped blocks deflector under the action of centrifugal force and disconnect with the inner and outer rings to achieve wear-free operation. When the inner ring runs in reverse, the shaped block is in contact with the inner and outer rings under the action of the spring, and the wedge is tight into one to withstand the reverse torque transmitted by the inner ring.
