SECTION 4: Installation (continued)
4.1.6.3. Bronze Gear Reducer oil must be SAE140 Steam Cylinder Oil meeting
AGMA #8 Compound, MIL SPEC, MIL-L-15016A; symbol 3150 (see
Chart 1 in Section 3 for capacities). (Or manufacturer’s specified oil if
not an Industrial Motion Control manufactured reducer.)
4.1.6.4. Be sure optional controller is properly fused – refer to vendor’s manual.
4.1.7. Check the adjustment of the Switch cam if your unit has this option. To insure
unit stops in dwell, see Figures 5 and 6.
4.1.7.1. A standard roller gear indexer shown in Figure 5 with a Brake Cam &
Limit Switch shown with the keyway in the center of the dwell period. It
is necessary to phase the Brake Cam such that the input shaft of the
indexer stops during the dwell period of the index cycle while leaving
enough of the dwell period for the input shaft to accelerate to full speed
before leaving the dwell period.
4.1.7.2. If the indexer has a drive code which causes multiple indexes per
camshaft revolution (i.e. X2, X3, etc… drive codes), additional lobe(s)
on the Brake Cam are required. The lobes will be equally spaced.
Therefore, phasing the one lobe of the Brake Cam to one dwell period
on the indexing cam will, in most cases, cause the other lobes to be
correctly phased with the other dwell periods.
NOTE: The lobes on the Brake Cam of PN series indexers are
formed by removing material from a shaft collar rather than a
protruding lobe. This will make a difference in the setup of the limit
switch and the control.
NOTE: Controllers are normally shipped loose and brake cam / limit switches are
mounted to the unit. However, neither are set or adjusted at the factory. Limit
switch and cam must be set to initiate the stopping cycle. Controller must be set
for the load & speed of the application per instruction in the vendor’s manual.
NOTE: The switch and brake cam commonly provided to initiate the stop cycle
cannot be used to indicate “on station.” A second switch and brake cam should be
ordered for this purpose.
