Box reductora planetary: it covers all the needs of accionamiento piñón-zip

Picture of Box reductora planetary

This box reductora planetary for applications of piñón-zip offers characteristics regarding rigidity, especially thanks to the technology of piñón of exit of an alone piece invented by Redex. It provides an only radial rigidity that represents until 60% of the total rigidity.

The range KRP+ of Redex Andatex is one of the widest of the market when covering all the needs of accionamiento piñón-zip in the sector of the machine-tool, including machinery of portico of very big dimensions. The rank of values of pair oscillates between 220 and 10.000 Nm depending of the model. The values of tangential strength by his part go of 8.246 to 153.333 N, whereas the relations of available reduction are of 22 to 140. The range KRP+ characterises by his excellent relation capacity/size when treating of a more compact unit.

This range is excepcionalmente rigid, something necessary for the applications of accionamientos piñón-zip more demanding. The range KRP+ finds available in the 6 universal sizes standard. For the size 6, the rigidity torsional is of 5.500.000 Nm/rad, whereas the radial rigidity is of 960.000 N/mm and the axial rigidity is of 6.194.000 N/mm, surpassing clearly the standards of the market.

KRP+ Can use individually or by pairs. In the second case, the precarga allows that it do not do game. In any case, is a solution indicated for systems of high precision.

The rigidity of KRP+ is a consequence of his design with piñón of exit integrated cheese cheese and cojinete of exit reinforced. The piñones of exit are mechanised to have the same diameter that the axles, which provides an optimum commitment between pair transmisible and rigidity in the zip.

The cojinete of exit consists in two cojinetes of rollers of angular contact precargados and notably sobredimensionados. This construction allows that the cojinete sustain the piñón the more near possible of the strength, since so only the thickness of the nut of fixation separates the piñón and the cojinete of exit. Besides, his reduces considerably the flexión radial, that is responsible of the 60 percent of the total distortion and however still sees badly managed by the existent systems.

The result is a greater dynamic precision thanks to his capacity to displace loads more weighed to greater speed. His provision regarding rigidity join to his greater accelerations with low inertia (until 25 m/s2). Like consequence of this, the frequencies of resonance of the systems of accionamiento to which incorporate can see increased of significant form.
