3.4.3 Drive
Be sure to connect the input shaft to the driving gear properly. Driving gear (gearmotor or crown gear)
connection must ensure absence of torsional slacks and accurate concentricity.
3.4.4 How to identify drive input/output shafts
In case of standard indexers, since the dimensions of shafts are exactly the same, to avoid faulty
assembling, two plates have been located nearby the shafts, the "INPUT" plate identifying the input drive
shaft and the "OUTPUT" plate identifying the output drive shaft.
Whereas, as regards IP-165, IP-200, IP-250 and IP-315 series indexers, since they are equipped with
hollow throughshafts, the input drive shaft can be easily identified by the presence of the key seat.
3.5 Stop
Remove the lube oil from the indexer and get rid of it in conformity with the reference rule for oil (AGIP
BLASIA 320) and petroleum grease (AGIP GR MU/EP) disposal.
4. Operation
4.1 Indexer performances
Paradromic indexers are mechanical components where input shaft uniform rotation is transformed in
output shaft intermittent and oscillating motion.
4.2 Static loads
The indexer is equipped with bearings in order to support radial and axial loads.
It is necessary that axial and radial load values applied to the indexer are lower than maximum allowable
values shown in the table Ip04.
4.3 Torque
A correct and safe use of the indexer implies the respect of allowable torque values owing to mass action
inertia, friction and presence of working forces considered as external forces with respect to the system.
Each indexer torque values in Nm and relavant motion law coefficients Ca, Cv and Ck are indicated in the
indexer technical features.
4.4 Wrong use risks
If static load values applied to the indexer are too high (see point 4.2), they will lead to the following risks:
- Non-conformity of precision tolerances;
- Bearing early wearing;
- Bearing structural failure.
If torque values applied to the indexer are too high (see point 4.3), they will lead to the following risks:
- Indexer early wearing (followers, in particular);
- Indexer damaging or breaking (followers and cam).
4.5 Residual risks
Although the indexer are designed in conformity with UNI EN 292 standard safety requirements, there are
still some residual risks which can be eliminated only during indexer assembling on final user machine.
Particular caution is recommended when assembling movable parts to prevent the following risks:
Movable part
Type of risk:
(*) This type of risk is connected with microswitch and timing cam application.
To prevent the above mentioned risks, it is recommended that the final user provides for suitable
safety-guards.
The selection of technically suitable safety-guards depends on the type of application and however shall be
in conformity with reference rules.
4.6 Unauthorised uses
The correct use of indexer implies cycle start and stop during dwell time. Different operation conditions
can lead to higher stress and consequences as indicated in section 4.4.
