Mayr celebrates 10 years of Smartflex couplings

A Mayr Transmissions product story
Edited by the Engineeringtalk editorial team Nov 13, 2008

Backlash-free shaft misalignment compensation couplings from the Smartflex series feature a direct clamping system for the flexible steel bellows.

This clamping system ensures optimum centring of the bellows to the shafts and provides high running quality and torsional rigidity of the coupling.

On steel bellows couplings with conventional radial clamping hubs, radial misalignment on the shaft by half the tolerance backlash occurs during installation.

This reduces the running quality and the misalignment capability of the coupling.

This year, the backlash-free steel bellows coupling system Smartflex from Mayr is celebrating its 10-year anniversary.

The Type series was launched onto the market in 1998 with three sizes and a nominal torque range of 40 to 200Nm.

At present, the Smartflex series features six sizes and covers a torque range of 16 to 700Nm.

Smartflex steel bellows couplings are used in machine tools, gear technology, packaging machines and specialised machines.

The main feature of the Smartflex range is the modular construction system, which makes it possible to adapt steel bellows couplings to the specific requirements of customers by plugging a few individual parts together.

The coupling consists of five core components: steel bellows, two reducing bushings and two clamping rings.

The steel bellows are available in several lengths per size.

The customer has the choice between high torsional spring rigidity with low misalignment capability or maximum misalignment capability with lowest coupling restoring forces.

Two reducing bushings with cylindrical or tapered bores are used for adapting the coupling to the customer's shaft dimensions.

The two clamping rings provide frictional locking and therefore completely backlash-free securement of the steel bellows to the reducing bushings or the shafts.
