Elastomer dog couplings with conical hub and clamping ring (similar to DIN 69002)
  • Elastomer dog couplings with conical hub and clamping ring (similar to DIN 69002)
DescriptionMaterial:Elastomer spider polyurethane with Shore hardness 98-A.
Hub aluminium.
Conical ring carbon steel.
Note:This coupling series is particularly suitable for use in high speed main spindle or drill spindle drives. Before the plug-in assembly, both clamping ring hubs must be fastened to the shafts with the correct tightening torque. Lightly oil the spider to ease assembly.Assembly:The shaft to hub bore fit should be a transition fit. The play should be max. 0.02 mm. i.e:
shaft Ø 25 k6
bore Ø 25 G6.
Bores smaller than D min. are possible, however an optimal transfer of the nominal torque is no longer guaranteed.
On request:Hub bores D1 and D2 with separate tolerance class or range.Drawing reference:
