Locking Bushes (Friction- Clamping- Torque)
lakehurstpt_update064004.gif
Copyright remains the property of Lakehurst Limited
These Ranges of Locking Bushes are a relatively New Product line and have become more and more popular recently, as it removes the need for the more traditional method of a Key to lock the component to the shaft.
This is acheived by applying an Axial pressure on the two apposing Cone Discs by way of the tightening screws causing the coned discs to slide over each other increasing the internal and external diameters and thereby applying transmission of torque between the shaft and the part that is fitted to it, eliminating any play between the shaft and the driven part and providing uniform distribution of the load over the entire diameter.
They are Two main types Self Centering and None Self Centering, with further types for Low to Medium, Medium to High and Very High Torque requirements, and are easily to maintained and quick to fit.
