Gear Couplings TNZ: Solutions for Heavy Load Applications

In industrial transmission systems, superior power and reliability of the machinery system are very important. In which Gear Couplings stand out with the Ringfeder TNZ series as the first choice of engineers for heavy-duty applications. This coupling can operate in the most demanding environments, ensuring seamless, uninterrupted transmission. The following blog will help you explore the features and applications of Gear Couplings TNZ suitable for many industries around the world.

1. What is Gear Couplings TNZ?

The Ringfeder Gear Couplings TNZ is a coupling designed to connect to the shafts of the motor, helping to transmit high torque during operation. These couplings have a very compact design, resulting in a high power density. The coupling housings have a straight internal toothing whilst the hubs have an external toothing with a chased variable radius. As a result, the hubs can move spatially within the housing and thus compensate for angular, radial and axial shaft misalignment of the adjoined shaft ends within specified tolerances.

These couplings are designed to accommodate misalignment, reduce vibration, and handle high torque loads, making them ideal for steel production, refining, and timber processing industries. These include particularly heavy-duty applications, e.g. in the direct drive of conveyor systems, mixers, rolling mills or roller tables.

2. General Features of RINGFEDER® TNZ Gear Couplings

The Ringfeder TNZ Gear Couplings are reliable couplings for heavy duty applications. To meet that, their design provides outstanding durability, along with the following outstanding features:

2.1. Flexibility and Misalignment Compensation

- Gear Couplings TNZ provide flexibility in installation and operation because they can accommodate several millimeters of axial movement of the motor.

- Ringfeder TNZ has the ability to compensate for a variety of misalignments such as:

+ Angular misalignment compensation: The coupling allows an angular misalignment of 5 degrees, helping to compensate for shaft misalignment even when the shaft is not aligned during operation

+ Radial misalignment compensation: This ability makes the coupling suitable for mounting with a variety of motors

2.2. High-Quality Materials and Construction

- Gear Couplings TNZ are manufactured from high-quality stainless steel, making operation safer and reducing maintenance downtime

- Ringfeder also offers gear couplings with higher quality materials for extreme stress applications

- O-rings made from NBR rubber are used to fill gaps, preventing leakage and contamination by other substances

2.3. Robust Assembly and Fastening

- High-quality bolts, developed explicitly for the TNZ series, are used to fasten the sleeves securely.  

- The half-coupling is centered using high-strength locating screws and self-locking all-steel nuts, ensuring precise alignment and stability.  

2.4. Long Service Life and Low Maintenance

The use of special gaskets allows to increase the temperature limit up to 120 °C, combined with the toothed edges of the couplings, which help them to extend the motor life, with low maintenance costs

3. Applications of Gear Couplings TNZ in Key Industries

3.1. Steel Industry

This industry is always mentioned with heavy machinery and a harsh operating environment. Gear Couplings TNZ is used in steel mills, used to install machinery such as conveyors, rolling mills, coiling machines and engraving machines. This coupling is capable of ensuring axial, radial and angular misalignment, transmitting torque reliably, helping the machinery operate smoothly.

3.2. Refining Technologies

In the field of refining technology, Gear Couplings are highly torsional flexible couplings with deflection compensation capabilities, ideal for use in drives of pumps, compressors and other machinery. The TNZ series has high durability, saving maintenance costs for refineries.

3.3. Timber Industry

Gear Couplings TNZ meet the requirements set by the woodworking industry: The coupling realizes maximum torque transmission between the mill and the drive motor and provides shaft misalignment compensation, which is indispensable due to the mill's shaft adjustability. Furthermore, the flexible coupling solution is characterized by precisely defined torsional flexibility, preventing excessive or premature wear or failure of the mill, which would otherwise result in additional costs for the user.

4. Products of Ringfeder TNZ series

Ringfeder Germany offers a wide range of products in the TNZ series with outstanding features and diverse applications for industries: Below are the current products of the TNZ series:

- TNZ ZCA / ZCB: is a torsionally rigid and gapless gear coupling, consisting of two coupling hubs connected by pre-mounted bolts.

- TNZ ZCAU / ZCBU: equipped with a long shaft, the length of which can be adjusted according to factory requirements.

- TNZ ZCAUU / ZCBUU: consists of two identical universal extension Hubs.

- TNZ ZCAF / ZCBF: is made up of the coupling halves of the TNZ ZCA coupling and supplemented by an intermediate shaft and two rigid counter flanges.

- TNZ ZCAK / ZCBK: is a Type with a standard hub limiting the end float to fix the shaft with a bushing bearing.

- TNZ ZCAV / ZCBV: suitable for vertical installation. For this purpose, TNZ ZCA is equipped with support plates that hold the bushings in a vertical position.

- TNZ ZCAZ / ZCBZ: supplemented with a spacer that is installed between the bushings of the TNZ ZCA coupling using pre-installed bolts.

- TNZ ZCH: consisting of a one-piece housing with O-ring supports on both sides and two shafts on the TNZ ZCA. Combinations with long shafts (ZCHU and ZCHUU) are available.

Additional Models: TNZ ZCA-BS / ZCB-BS, TNZ ZCA-BT / ZCB-BT, TNZ ZCHU, TNZ ZCHUU
