7.2.3 Gear unit with backstop
Observe details at item 5.8, "Backstop"!
Before start­up, check whether the backstop can be turned manually in the free­wheeling direction without
exerting undue force. Observe the direction­of­rotation arrows on the housing.
To avoid damaging the backstop or the gear unit, the motor must not be run
adversely to the stop direction of the gear unit.
Observe the notice fixed to the gear unit.
The minimum lift­off speeds must not be exceeded during operation.
If a backstop with release mechanism is used, the operating instructions for this
backstop must be followed.
Moreover, the dimension "x
min.
" must be checked; "x
min.
" must not be smaller
than that stated on the backstop rating plate.
Before connecting the motor, determine the direction of rotation of the three­phase current supply using
a phase­sequence indicator, and connect the motor in accordance with the pre­determined direction of
rotation.
The unit can be started up once the amount of oil indicated on the notice has
been poured in through the oil filler plug screw of the backstop. Always use oil
of the same type and viscosity as for the gear unit.
7.2.4 Gear unit with overrunning clutch
Observe details at item 5.16.3, "Overrunning clutch"!
Before start­up, check whether the overrunning clutch can be turned manually in the free­wheeling
direction without exerting undue force. Observe the direction­of­rotation arrows on the housing.
The overrunning clutch is in free­wheeling operation if the motor shaft of the auxiliary
drive is rotated in opposed operating direction of rotation.
When rotating in the operating direction of rotation, the blocking action of the
overrunning clutch (carrier operation) becomes effective. Coupling and, thus, rotation
of the output shaft of the main gear unit in operating direction of rotation takes place.
In the case of auxiliary drives designed for load operation, the brake at the auxiliary
motor must first be lifted in order to check for proper functioning of the overrunning
clutch.
The overrunning clutch is accommodated within the intermediate flange and is supplied with oil from the
main gear unit.
7.2.5 Temperature measurement
During first start­up and after maintenance work, the oil sump temperature must
be measured during correct use (maximum machine performance) after
appropriate running in.
The maximally permissible oil­sump temperature is 90 °C (for mineral oil)
or 100 °C (for synthetic oil).
At higher temperatures the gear unit must be shut down immediately and
FLENDER customer service consulted.
