Oil heater:
In case of low temperatures and/or pressure-fed lubrication systems, the oil heater must be used. This is a resistor that,
through temperature sensor and PLC (to be provided by the customer) pre-heats the oil and takes it to a suitable
temperature for start-up.
T start-up = T oil = 18 °C
T stop = T oil = 40 °C
If possible, start the oil heater 4 hours before starting the gear reducer.
For any technical information, please contact MOTOVARIO TECHNICAL SERVICE.
In any case, refer to the installation manual of the part to be assembled.
Danger due to electric voltage!
Have the operations carried out only by specialised personnel.
Before starting the operations, make sure that the oil heater is connected to the power supply and take
measures against unexpected triggering!
Take special care when installing the oil heater. Its wrong installation can damage the gear reducer; to
avoid damage, make sure that the heating elements are immersed inside oil.
A wrong change of the mounting position, or a wrong or unsuitable wiring, can damage the oil heater.
Periodically check the correct operation.
8.4.2 Lubrication and monitoring systems
Bearing lubrication pump:
The mechanical pump is used in case of gear and bearing pressure-fed lubrication. It is mechanically driven by a gear
reducer shaft. It can feature monitoring and operating devices.
For any technical information, please contact MOTOVARIO TECHNICAL SERVICE.
In any case, refer to the installation manual of the part to be assembled.
Pay special attention to oil viscosity, mainly during start-up; if necessary, pre-heat the oil
Periodically check the correct operation.
Bearing lubrication motor pump:
The motor pump is used in case of gear and bearing pressure-fed lubrication. It is independently powered and can
feature monitoring and operating devices. All connections must be implemented by the customer.
For any technical information, please contact MOTOVARIO TECHNICAL SERVICE.
For PBZ, the motor pump is supplied already assembled on the gear reducer. For the overall dimensions, contact
MOTOVARIO TECHNICAL SERVICE.
In any case, refer to the installation manual of the part to be assembled.
Pay special attention to oil viscosity, mainly during start-up; if necessary, pre-heat the oil. Activate the
motor pump first and activate the gear reducer only after a few minutes of operation of the motor pump.
Periodically check the correct operation.
