Cycloidal gear reducer / low-backlash - 1 arcmin, 58 - 44 145 Nm | RV-E series

RV-E gears are the right choice for demanding drive tasks. If high torsional rigidity and tilt stability, as well as a compact design with large reductions are required, this is the solution.

The RV-E series combines the RV gears with large, integrated angular ball bearings. They absorb extreme forces and torques. An additional external bearing is unnecessary. The result is precision gears in a compact design with extreme rigidity and a permanently constant operating behaviour. The nearly one-hundred-percent contact within the trochoidal pin construction and the even distribution of force within the gear enable a high load with little play. Thanks to this design, the RV-E gear achieves a high level or repeat accuracy and path accuracy. In the zero crossing of the hysteresis the maximum opening is one angular minute.

Cycloidal gear reducer / hollow-shaft - 98 - 44 100 Nm | RV-C series

The RV-C gears have an identical design and the same quality features as the RV-E gears. However, they have a hollow shaft with a diameter of 150 millimetres. This hollow shaft is an excellent means of routeing supply lines, data cables and media or drives.

Cycloidal gear reducer / low-backlash - 1 arcmin, 137 - 5 390 Nm | RV series

The RV series serves as the foundation of the entire Nabtesco product range. RV gears are components sets without integrated angular ball bearings. Due to the external bearing, they are very compact and are distinguished by their high torsional rigidity. The customer is free to choose the type of output bearing.

The power transmission takes place through rollers. In doing so, the gear has a high degree of efficiency, a long service life and extremely low backlash. The nearly symmetrical gear construction and the roller bearing support of all shafts guarantee a constant operating behaviour over the entire service life. In addition, it enables momentary load peaks of up to five times the indicated rated torque, which could arise in emergency stop situations, for example.

Cycloidal gear reducer / waterproof / for robotics - IP67 | RV-F series

The RV-F series gears are an additional variant of the RV-E series. Nabtesco develops these gears specially for use in robotics. Their typical design feature is the sealed output side. A double oil seal prevents the penetration of fluids and other media into the gear, thus achieving protection class IP 67. The seal expenditure for the customer is lower than for conventional gears.

Cycloidal gear reducer / hollow-shaft / for rotary table - 1 471 - 9 807 Nm | NT series

High precision, high output speeds and a high degree of efficiency - these are the demands a drive unit should live up to for use in rotary tables. The NT series from Nabtesco meets these requirements. Thanks to their RV gear design, the NT reduction gears are extremely resistant to impact loads. The hollow shaft enables the central routeing of various cables, media or rotary movements. The contact between the trochoidal disc and housing takes place through rollers. This reduces the wear and increases the service life and reliability.

The NT gears offer additional decisive advantages over conventional rotary table drives:

The output achieves and output speed of 100 rpm.
The gears achieve a degree of efficiency of 80 per cent.
The reproducibility lies at +/- 1.0 arc second.
The indexing precision is +/- 2.5 arc seconds.
The assembly times are reduced, because neither an adjustment of the backlash nor the pre-tensioning or the adjustment of the concentricity is necessary.
