GEARex - Model FA -Steel Gear Coupling
GEARex couplings made from steel with grease lubrication and toroidal sealing ring correspond to the international standard. Being flexible shaft connections they are suitable for a positive torque transmission. In addition, they ensure to compensate for axial, radial and angular shaft displacements.
According to the operating principle of the well-known crowned gear edge pressures in the spline are avoided in case of angular and radial displacements. Moreover, permanent grease lubrication produces a better friction ratio of the spline with an operation almost free from wear along with a long service life of the coupling.
In order to ensure a regular and verified lubrication in assembled condition, two connections for hydraulics are arranged opposite to each other radially on each coupling sleeve. As a result a complete GEARex® coupling has four connections being offset to each other by 90°.
The interior of the coupling is sealed by means of toroidal sealing rings (NBR 70 ShA). The feather keys have to be sealed against escape of lubricants during the assembly.
