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).
