El-Salvador HB Series Gear Units

Characteristic Features

Design Gear units are a completely new design.

Advantages are:

● more sizes with a reduced variety of parts;

● higher operational reliability combined with increased power capacity;

● predominantly non-contacting wear-resistant labyrinth seals are possible;

● flanged output shafts to facilitate assembly o f gear units in confined spaces (on request).

Mounting position Gear units can be supplied for either horizontal or vertical installation. Other arrangements are also possible on request. The basic gear unit can be optimally adapted to customer requirements by fitting different add-on pieces like motor bell housings,gear unit swing-bases or backstops.

Noise behaviour

New concepts were applied to clearly improve the noise emission of the gear units by:

● grinding the bevel gears;

● designing noise-absorbing housings by means of the MASAK computing program;

● and achieving exceptionally large contact ratios.

Thermal conduction

gear units not only have a high efficiency but alsoa favourable thermal conduction

● through enlarged housing surface areas;

● because non-contacting labyrinth seals can be used;

● and because large fans incorporating a new type of air conduction fan cowl are being used

The selection of gear units is based on a lower maximum oil temperature. By that, the operational reliability will be increased and the cost of maintenance reduced due to longer oil change intervals.

Storing

Gear units have been designed according to a new unit construction principle. Through this, the variety of parts could be reduced. The parts are mainly on stock enabling gear units worldwide to deliver at short term.
