The planetary gearbox for AGVs. Compact and highliy resilient.

Description

With the newly developed NGV we are introducing a new planetary gearbox whose product features are specifically intended for use in automated guided vehicles (AGVs). The bearings play a major part: they are designed and positioned so that high radial loads are possible at the output side.
AGVs transport heavy loads 24/7 on a continuous basis – and therefore make uniquely high demands of the design and the mechanical system. Particularly with regard to the gearbox, this means that because the gearbox of AGVs is usually located directly in the wheel, depending on the running gear principle the entire weight consisting of the vehicle and the payload acts directly upon the gearbox output bearing. This results in high radial loads. Furthermore, the naturally confined space situation inside the vehicle means that the gearbox must have an extremely compact, space-saving design.
The new NGV planetary gearbox fulfils these special requirements using pre-stressed inclined roller bearings. These can absorb a considerable amount of force due to their design. The wheel does not have to be supported separately, since the load is supported by the bearings at the output.
The interface between the gearbox and the chassis has also undergone consistent optimization in the NGV: the mounting flange of the gearbox is positioned so close to the chassis that it can be mounted there directly. Another advantage in addition to the ease of installation: the motor and the gearbox can be pre-assembled as a unit and installed together. It is possible to attach almost any motor because of the use of a wide range of motor adapters. The wheel itself is fitted directly to the flanged output shaft from the outside and can therefore be exchanged quickly and easily if required.
