End Engineered
Class Pulleys |
- these designs eliminate some of
the acute deficiencies of other designs
1) dynamic stress
analysis
optimizes final
geometry
minimizes
stress concentrations and alternating stress ranges
maximizes
pulley’s life and reliability
eliminates the
cost of downtime
2) hub weld is
eliminated, the most significant cause of pulley failure
3) keyless compression fittings are used so shafts no
longer have to be keyed

| Turbine
End Plates (with B-LOC 112) |
 |
- machined from single steel plate
or casting
- both sides are contoured for
centered loading and stress equalization
- eliminates pulley stress
concentration at the hub
- weld prep is done at the joint to
the rimplate
- wider hub allows for symmetrical
loading from double acting locking devices
results in superior handling of bending moments
-
typically used with B-LOC 112
series keyless fittings or any tapered bushing
- recommended for belt tensions
between 25,000 lbf and 50,000 lbf
