  • One major difference between RF and AC joint is that the RF joint is round and the AC joint Due to an elongated track compared to AC joints, UF joints allow for a greater maximum flexion angle (up to more than 50 ° compared to about 47 ° for AC)
  • a DO joint is a special sliding joint For the rolling elements, which run parallel to the axis of the joint, maximum deflection angles of up to approximately 31 ° are to be attained In principle, it should be noted here that all projecting joints can be bent as desired within a range of 0 ° up to the maximum bending angle.

If the shaft is bent as far as possible, the "maximum deflection angle" is present.From the above explanations regarding the joints shown here, it can be seen that at least the UF elements have at least one U-turn angle. , RC, AC and DO joints satisfy this condition since they all have a maximum flex angle above 25 °.
  • the inner part comprises a tempering steel.
  • the tempering steel has the property of being directly curable. This is largely attributable to its carbon content of 0.3% to 0.8%. After tempering, the tempering steel usually has a high toughness and a fine-grained structure. These toughening properties are particularly suitable for absorbing the forces occurring at large bending angles. The possible heat treatments will be explained later in detail, at this point is only to point out that under “tempering” here the direct hardening followed by tempering is understood, which may take place partially or for the entire hinenteil.

This means that, depending on the contact of the force-transmitting components, different levels of stress concentration occur below the surface.
  • a hardness increase or increase in strength of more than 3 times the basic hardness of steel is required (eg from 180 HV to 58 + 4 HRC).
