general geared box

3.Because large fans incorporating a new type of air conduction fan cowl are being used..

2.Through enlarged housing surface areas.

1.The gear units have a high efficiency.

PV series gear units a favourable thermal conduction,because:

Thermal conduction:

All key components are finished by precisely maching;grinding the gears;designing noise-absorbing housings;accurate assembly,and finally tested,and therefore,fairly low noise is reached.

Low noise:

Under the condition of accueately selecting type size and the normal maintenance and use,main components(expect those easily-disabled parts) can last as long as up to more than 50,000 hours.

Long service life:

The gear units can be supplied for either horizontal or vertical installation.Other arrangements are also possible on request.

Mounting position:

2.Higher operational reliability combined with increases power capacity.

PV design:1.Highly standard modular designed, more sizes with a reduced variety of parts.

PV series gear unit is a completely new design.There are two types of helical gear unit and bevel-helical gear units.
