Telescoping members

Lengths. Splined telescoping members have a CUNA involute profile. Thrust forces generated by the transmitted torque is divided among the spline teeth. Rilsan-coated triangle profile tubes Triangle profile tubes The Rilsan coating on the inner tube helps reduce telescopic thrust.These tubes are recommended for shaftsthat have to slide for long lengths under loads, e.g. primary drivelines of towed implements when going around turns. Rilsan coated triangle profile tubes arestandard on drivelines fitted with 80° and70° constant velocity (CV) joints. Thethickness of the Rilsan coating iscompensated for by a thinner outer tube, that is different from a regular tube. Splined telescoping members Triangle profile tubes are designed to provide maximum resistance and optimal telescoping. The profile will only couple so the joints are properly in phase with respect to each other. Splined telescoping members can satisfy the requirements of applications with high torques, frequent sliding under load and extensions longer than those permitted by regular telescoping tubes or maximum extension tubes. See chapter 6 Triangle profile tube with heat-treatedinner tube Applying heat treatment to the inner profile tube increases the surface hardness.Heat treated tubes are usually chosen forshort drivelines that work in aggressive environments (abrasive particles) and aresubject to frequent short sliding, e.g. theprimary driveline of towed implements.Heat treatment does not effect the thicknessof the tubes, so a regular outer tube is used.
