Shaft diameter d Peak drive torque T, determined as the nominal operating torque multiplied by an application-specific safety factor to account for stall or start-up conditions, mass accelerations, impact loads, etc. Safety factors are left to the design engineer, though we are happy to offer guidance based on our experience. Nominal torque is determined as follows:

| For
applications involving torque only, the next step is to review specifications
for Locking
Assemblies and/or
Shrink Discs to identify a unit
for the given shaft diameter d where the rated torque
capacity of the B-LOC (Mt
in the specification tables) is equal to or greater than T.
This will ensure that the B-LOC will not slip under even the
most severe operating conditions. Note that B-LOC Shrink Discs
will each accommodate a range of shaft diameters, and that rated torque
capacity for a particular size Shrink Disc increases as the
shaft diameter increases. Use the following general guidelines when choosing between a Locking Assembly (internal style) and a Shrink Disc (external style): |

* For hydraulic motor applications with shafts 4" and under, as well as for rigid shaft-to-shaft connections, please also consider our WK Coupling. A
general rule for either type of B-LOC is that the mounted
component should be at least as wide (preferably wider) than the
"L" dimension of the B-LOC you select. An
important exception to this rule is the use of single-taper B-LOCs
to mount plate sprockets (for assistance with these applications,
please contact us.) |
