Oldham-type couplings clamping with grub screw
Couplings
Description
Centre disc polyacetal. Hub aluminium. Note Clamping the hub with a grub screw is a costeffective alternative to the Oldhamtype couplings with radial clamping hub (23030). Short mounting times. The couplings can be mounted completely assembled or a plugin assembly is also possible. Take note of the tightening torque for the grub screw. To ease removal we recommend milling a flat on the shaft. Assembly The shaft to hub hole fit is a transition fit. The play should be min. 0.01 mm and max. 0.04 mm i.e. shaft Ø 6 f7 hub Ø 6 H8. Advantages robust plugin playfree short design On request Hub bores D1 and D2 with separate tolerance class or range.

Spider polyurethane hardness Shore 98A. 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 plugin 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 D1/D2 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.

D1 and D2 are customer specific e.g. 230122025; D1 = 5H7, D2 = 8H7 Note Zero backlash, torsionally rigid, resiliently flexible and maintenancefree full metal coupling for transmitting angle synchronous rotary movement. The innovative slit structure makes possible a very good axial, radial and angular flexibility with low reset force. Ideal for servomotors. Assembly Recommended shaft tolerances h7.

Steel 1.0718. Stainless steel 1.4305. Version Steel black oxidised. Stainless steel bright. Note Rigid couplings transmit high torques without rotational play. They are used where there are no shaft displacements or alignment errors. Wearfree and maintenancefree. Screws secured to avoid vibration induced loosening. The maximum torque transmission can only be achieved through optimal installation and correct shaft dimensions. Maximum speed 4000 rpm.

Keyless locking coupling with low mass and moment of inertia. Easy to connect and release – no jamming on the shaft. Perfect for zero backlash connections. Excellent concentricity and running. Suitable for keyed and keyless shafts. for shaft diameters from 5 to 35 mm for high torques minimum axial offset when mounting selfcentring Assembly Shaft and hub must be free of oil, grease and dirt. Do not lubricate keyless locking coupling. Insert keyless locking coupling in the hub seat and slide onto shaft. Tighten nut by hand and use a torque wrench to tighten to the defined tightening torque. Tolerances Shaft diameter and hub hole Form A ±0.04 mm. Form B ±0.08 mm. Surface quality Rz ≤ 16 µm.
