Descriptions:

Compact, and yet extremely powerful, are the units of the 300 Planetary gear reducer series. Their

planetary drive train makes them the ideal choice for all the severe duty applications where shock loadings

and impacts are more the rule than the exception. The product configuration is highly versatile, due to

several options as far as the mounting, the gear layout, the output shaft and the motor interface. All the

features are available for each of the 18 finely spaced frame sizes, spanning over the 1.000 - 1.400.000

Nm torque range. Finding the perfect match to any drive problem is therefore more than a wish, it is

something users can safely rely on - always.

Your benefits:

1. Compact design, high torque density

2. Low backlash, high torsional stiffness

3. Low moment of inertia, high dynamics

4. High efficiency, low noise

5. Excellent cost-performance rate

6. Easy motor mounting with clamping connection

7. Maintenance free, universal mounting

Transportation facility, lifting equipment, and variable pitch), Coal Mine Machinery(Excavator), etc

Maintenance:

After 300-hour operation, please change the oil, and flush the gear unit with suitable detergents.

Pls do not mix the mineral oil and synthetic oil.

Pls check the oil level in regular time.

The cause for breakdown and settlement of reducer:

Breakdown	Possible cause	The way of settlement
The motor does not run in case of loading	Voltage is too low	Check to see if the wire is too long or too thin
	Gear is damaged	Repair it in special factory
	Work with overload	Discharge load
Very hot	Work with overload	Discharge load
	Start and stop too many	Discharge load
	Bearing is damaged	Reduce using frequency
	Voltage is too high or too low	Repair or replace
Loud noise	If the noise is loud and continuous, the bearing is damaged or the gear damaged	Repair it in special factory
	If the noise is loud occasionally, the gear must be damaged or something else block	Contact with the service institution

Storage:

1:Pls do not store in outdoor.

2:pls put cardboard, wood or other material between the products and floor. the gear box cannot directly

touch the floor.
