The elastic coupling Nil Union models S/LS are made up of metal pinions and nylon crown. Thanks to the mechanical properties of the nylon used in these crowns, there is no wear on their contact surface, they have great power to absorb vibrations and high mechanical resistance.
Applicable to torque limiters, clutches, brakes and everything that requires assembly of two aligned shafts.
These deviations can be presented in three different ways:
- Parallel or radial misalignment: occurs when the centerlines of the shafts are parallel apart.
- Angular or axial misalignment: in this occasion the deviation is observed by the angle formed between the central lines in a plane in space.
- Combined misalignment: This is the most common of the situations, and occurs exactly when there are both parallel and angular deviations in the same set of centerlines.
