Motovariators series TX

WAREHOUSE STORAGE

When moving the unit, care should be taken to protect external parts from breakage

or damage due to accidental knocks or falls.

If the unit is to be stored in a hostile atmosphere or for a long time (2/4 months), it is

important to apply protective and waterproofing products to avoid deterioration of shafts

and rubber parts.

Before starting up the unit, carry out the following checks:

Check the data shown on the name plate of the variator and/or the electric motor;

Check for any leaks of lubricant

If possible, remove any traces of dirt from the shaft and from the areas around the oil

seal.

If the oil seal is not immersed in the lubricant inside the assembly during particularly

long storage periods (4/6 months) it is recommended that it should be replaced as

the rubber might stick to the shaft or even have lost the elasticity it needs to work

properly.

INSTALLATION

Particular care must be taken when installing drives, and is often the source of

damage and of down time. Careful choice of the type of drive and mounting position

can often avoid the need for protection of sensitive areas, particularly underneath the

unit from oil leaks, however limited they may be.

The machine must be firmly fastened in place in order to prevent any vibrations

Whenever possible, protect the variator from direct sunlight and bad weather,

especially when it is mounted on its vertical axis

Make sure the air intake on the fan side is unobstructed in order to ensure that the

motor is correctly cooled

In the case of temperatures of < -10 °C or > +50 °C, contact Technical Assistance

If the motor is to be started up very often under load, the use of a heat probe inserted

into the motor is recommended

The various machine members (pulleys, gear wheels, couplings, etc.) must be

mounted on the shafts using special threaded holes or other systems that ensure

correct operation without risk of causing damage to the bearings or the external parts

of the assemblies (fig. 1)

Lubricate the surfaces that come into contact in order to prevent oxidation or seizure.

COUPLING NOTES

The pulley must be mounted on the output shaft as close as possible to the stop so

that it does not cause excessive radial load on the bearings (fig. 2).Great care must

be taken when connecting the couplings to ensure that they are well aligned, so as not

to cause excessive radial load on the bearings (fig.3).When it is applied, paint must

never be used on rubber parts: oil seal, etc. It must never be applied to any breather

holes in plugs if they are mounted on the unit.In the case of assemblies with oil plugs,

remove the closed cap used for transport and fit it with the breather plug that is

supplied with the variator.When the assembly is supplied without a motor, the

following precautions must be followed in order to ensure that connections are

properly made.

Mounting the motor on the pam B5 flange

Check that the tolerance of the shaft and the motor flange comply with at least one

normal class of quality. Carefully clean off any trace of dirt or paint from the shaft, the

centering and the face of the flange. Carry out mounting operations making sure not to

use force. If this is not possible, check the tolerance of the motor key and ensure that it

is correctly positioned. Apply assembly grease to the shaft in order to prevent oxidation

or seizure caused by contact.

Good quality motors should be used in order to ensure that the unit works correctly,

without vibrations or noise.

Use the oil window, if present, to check that the lubricant reaches the correct level

required for the mounting position used.

STARTING UP

The unit should be started up gradually: do not immediately apply the maximum load

the machine is able to take ; look for and correct any malfunction that may be caused by

incorrect mounting.

Running-in is essential for the variator to run properly since, notwithstanding the

modern construction techniques for the gears and castings, the extreme cleanliness

of the internal parts, and the excellent qualities of the lubricants used, the variator is a

drive operating by friction therefore it is necessary a certain adaptation of the internal

parts during the first running phases.

SERVICING

The high degree of finish of the internal parts ensures that the unit will work correctly

with only a minimum amount of servicing.

Generally speaking, the following rules should be followed: periodically check that the

exterior of the assembly is clean, especially in the cooling areas; periodically check to

see if there are any leaks, especially in the areas around the oil seals.

Assemblies that are lubricated for life and thus do not have any oil plugs do not require

any special maintenance except as stated above.

For the other assemblies, low maintenance is required with an oil change at 1000 hours

of use, and the following changes have to be done at 8000 hours of use. The change of

oil naturally depends on the type of environment and service.

Apart from the normal maintenance rules given above, make sure the breather hole in

the plug is clean and, using the oil window, periodically check that there is sufficient

lubricant.

Should it be necessary to top up with lubricant, use the same type that is already in the

variator or one that is compatible with it.

In case of doubtful incompatibility between lubricants, we recommend you empty out

the oil from the variator completely and, before refilling with new oil, wash out the unit to

remove any residue.

When changing the oil, follow the previous instructions.

TROUBLESHOOTING

If any problems should arise when starting up the unit or during its first few hours of

operation, contact the after sales service unit of Motovario.

The table shows a series of problems with a description of possible remedies.

It should be borne in mind however that the information given is for reference only as all

the drives manufactured by Motovario are thoroughly tested and checked before they

leave the factory.

Please note that tampering with the assembly without prior authorization from

Motovario immediately invalidates the warranty and often makes it impossible to

ascertain the causes of a defect or bad function.
