GEAR REDUCERS
CHARACTERISTICS OF THE GEAR REDUCERS
The PUJOL speed reducers series "S" are appropriate for driving all types of reduced speed machines and equipment requiring speed reduction.
A completely enclosed construction, allows for installation in the open air and hostile enviorements, such as moisture, dust and salt laden atmospheres.
The reducers are fitted with synthetic rubber oil seals and top quality ball bearings.
The direction of rotation of the output shaft may be clockwise or anti- -clockwise, as required.
The components of this speed reducer have been subject to strict controls throughout their production process.
Once mounted, this speed reducer has satisfactorily passed, among others, the following controls:
Noise volume, sealing, shaft eccentricity and misalignment, speed, power and finish.
GENERAL INSTRUCTIONS FOR MOUNTING
Ensure that the gear reducer are installed in such a way that they are mounted on a clean and flat surfaces, which wil not cause stress or tension in the gear reducer. It is
advisable to use a stretch coupling for transmitting the force directly from the speed reducer to the machine to be driven. The pulleys and pinions should not be forced
into the shafts by a hammer or mallet but should enter smoothly by the pressure exerted by a bolt screwed into the threaded hole at the end of the saft. Otherwise the
bearings could be damaged. We recommend a tolerance of H7 for the holes of the machine parts to be fitted on the saht.
LUBRICATION
This speed reducer have been constructed for splash lubrication with oil. Unless otherwise specified, the geared units is supplied without oil and it is the responsibility of
the customer to fill it to the required level and follow the maintenace instructions accordingly
The oil inlet hole has to be provided with the delivered breather plug which has to be put always in the
highest existing hole of the box according to the working position of the speed reducer.
With a price surcharge, the geared units can be supplied direct from the factory with long lasting grease lubrication, to which purpose the operating position of the reducer
must be indicated. In this case the geared units will not need any maintenance.
MAINTENANCE
After 500 hours of service empty the lubricant and refill the box up to the level. Once the running- -in period is over, monitor the status of the lubricant after 12000 hours of
work (approx. 30 months working 14 hours a day) (in case of synthetic oil) or 2500 hours of work (approx. 6 months working 14 hours a day) (in case of mineral oil)
and replace when necessary.
