An innovative (patent pending) concept for the modular design of planetary gearheads is being used for the first time. Performax^® drives combine high power density and smooth running. Compared with other similar specified products on the market, Performax^® gearheads offer outstanding power density* and excellent smooth running. Transmissions of up to 17:1 in the first stage allow the use of single-stage gearheads where competitors products already require a twostage design.

* transmittable torque in relation to the constructional space and the basic materials used

The design features of the series include helical plastic gear wheels in the first stage and - in the second stage - straight toothing in the zinc diecast casting with case hardened planetary wheels. Another special standard featuring the Performax^® gearhead is the second stage - planetary wheels that have needle bearings - this really sets the series apart from the usual planetary gearheads on the market.

Of course, the Performax^® drives, like all ZEITLAUF gear motors, have a ground and hardened output shaft available here in two different versions (feather key or face).

The motor assignment in the standard range modular system is power-oriented, meaning that a motor that effectively corresponds to the efficiency of the gearhead is assigned to each gear reduction.

At present, the Performax^® series includes four sizes 32, 42, 52 and 63, and will be extended still further in the future.

A true success story is continued in the form of Performax^®HRL. The innovative (patent pending) concept of the Performax^® series is now capable of managing the highest radial loads. This increases not only the application options of this excellent construction concept, but also its capabilities. Smoothness of running, gear reduction, torque, effectiveness or radial load - the top marks of Performax^®HRL delight every time. Deciding on Performax^®HRL means deciding on durable performance without the compromises.

NoiselessPlus planetary gearheads from ZEITLAUF® are the perfect combination of power and smooth running. Extremely quiet even under tough operating conditions, NoiselessPlus also copes with extreme radial loads and makes high reductions possible in one stage from 4.33 to 21 and in two stages from 26 to 231.

Wherever high ef?ciency is required under minimum noise development, the ZEITLAUF® planetary gearhead NoiselessPlus shows what it can do: Exemplary smooth running is achieved thanks to extremely sturdy, low-wear plastic planetary wheels in an aluminium housing with bevelled teeth. Double ball bearing output shafts ef? ciently absorb the forces acting on the shaft at high radial loads. The output shafts of the NoiselessPlus gearheads are made of hardened and ground case-hardened steel and are thus particularly durable. Standard torque transfer is through a feather key connection or face. If required, however, shafts with double faces, offsets, (thread) bore holes, holes or serration can be used.

When it is necessary to reduce motor speed with the least possible gear play, that's where the Focus series drives come in: due to their limited tolerances, a torsion resistant design and the use of high-quality production methods, Focus gearheads permit only minimum circumferential backlash. In the first gear stage, plastic wheels with helical teeth engage in an aluminium housing. The planetary wheels are centred on a carrier cage mounted on ball bearings, which introduces the transferred torque to the second stage. This has a hardened hollow wheel with spur teeth and likewise hardened steel planetary wheels. The planetary wheels of the second stage run on needle bearings on the planet carrier, which in turn sits on the ground and hardened output shaft that also runs on double ball bearings.
