Clutches are key components of many mechanical systems – they are responsible for connecting and disconnecting shafts to transmit torque. Although they are most often associated with automobiles, their application is much broader. They are found in industrial machinery, turbines, compressors or power plants, among others.

It was at one of the power plants that we had the opportunity to implement our next project, involving the precise steaming of steam turbine couplings.

What did the task consist of?

The purpose of the measurements was to check the correctness of the position of the holes in the two half-couplings relative to the holes located in the turbine shaft.

The scope of work included:

• Control of axial and radial spacing of holes against nominal values from technical documentation,

• Positioning of half-couplings during rollout,

• Inspection after installing new bushings.

We used precision 3D measurement systems for the job, which enabled us to maintain dimensional accuracy at every stage of the work.

The result: minimizing risk

The measures carried out minimized the risk of assembly errors, which could have very costly consequences in the case of such large components.
Misalignment of holes in the pairing of half-couplings would mean the need to redo the entire coupling – generating huge losses in time and money.

Thanks to our inspection, the customer was assured that all elements were made according to technical specifications and that the installation would go smoothly.

Why is it so important?

In components such as clutches, where dimensional tolerances are very tight, every hundredth of a millimeter matters.
Precise measurement and control of geometry in the pairing process is a guarantee of safety, reliability and durability of the entire drive train.

Precise measurements save time, money and nerves.
At TREON, we help customers in the energy and industrial sectors avoid installation errors by ensuring the highest measurement accuracy at every stage of the project.
