### 12.17 Power

P is the power transmitted per gear mesh. For multiple power paths load-sharing
must be considered:

- If the pinion meshes with two or more gears (or the gear meshes with
two or more pinions), use the power of the more highly-loaded branch.
- The degree of load sharing depends on the number of planets, accuracy
of the gears and mountings, provisions for self-aligning, and compliance
of the gears and mountings.

A load increasing because of shocks can be considered using the overload factor
K_{o} (see 12.20). The sizing button can be used to let the software calculate
the maximum power that can be transmitted with the gear set so that the
required safeties are reached (see 11.3).
