Description
The service factor (f.s.) depends on the operating conditions the gearbox is subjected to. Following parameters need to be take to select the right service factor.
type of load of the operating machine : A-B-C
length of daily operating time : hours/Days()
start-up frepuency : starts/hour(*)
TYPE OF LOAD:A-uniform,fa<=0.3
B-moderate shocks,fa<=3
C-heavy shock,fa<=10
Fa=Je/Jm
Je(kgm2) moment of the external inertia reduced at the drive shaft
Jm(kgm2) moment of inertia of motor
To install the reduction unit it is necessary to note the following recommendations
The mounting on the machine must be stable to avoid any vibration.
Check the correct direction of rotation of the reduction unit output shaft before fitting the unit to the machine.
In the case of particularly lengthy of periods of storage (4-6 months)if the oil seal is not immersed in the lubricant inside recommended to change it since the rubber could stick to the shaft even has lost the elasticity it needs to function proberl.
For a shaft mounting,for reduction units with a hollow output shafts use the torque arms motionclinic can supply. If it is make sure that the constraint is axially free and with such as play as to ensure free movement to the reduction unit.
Whenever possible, protect the reduction unit against solar radiation and fan side.
Ensure the motor cools correctly by assuring good passage of air from the fan side.
In the case of ambient temperatures(-5°C and) +40°C contact motionclinic.
The various parts (pulleys,gear,wheel,couplings,shafts,etc)must be mounted on the solid or bollow shafts using special holes or other systems that anyhow ensure correct operation without risking damage to the bearings or external parts of the uni.
Painting must definitely not go over rubber parts and the holes on the breather plugs,if there are any.
Taking out the seal embolism of the oilhole.
Check the height of the oil level.
Supposing the gear unit have not coupled with the motor, please pay attention to the following items to made sure rightly connection.Mounting to B5,B14.
Check whether the tolerance between the shaft and motor flange fit for the essential standard.
Washing the dirt and the paint on the surfaces of the shaft, center bore and the flange.
Mounting avoid the gear unit incur strength.
Check the position and the decination of the motor keyslot.
Lubricate the surfaces in contact to avoid seizure or oxidation.
Staring must take place gradually, without immediately applying the maximum load.
When there are parts objects or materials under the motor drive that can be damaged by even limited spillage of oil,special should be fitted.
