Overload factor

Symbol KA
Unit -
Attribute-ID application_factor_agma_2003
Numeric ID 9865
Value Type PMDouble

The overload factor KA considers all forces beyond nominal circumferential force that are introduced from the outside into the gear unit.

Ideally, the application factor is determined experimentally or by comprehensive system analyses. If no comparable information is available, the approximate values bellow can be used

according to AGMA 2003:

 Mode of operation of the driving machine Mode of operation of the driven machine
Uniform Slight shocks Medium shocks Heavy shocks
Uniform 1.00 1.25 1.50 1.75 or higher
Slight shocks 1.10 1.35 1.60 1.85 or higher
Medium shocks 1.25 1.50 1.75 2.00 or higher
Heavy shocks 1.50 1.75 2.00 2.25 or higher

The values given in the table apply to ratios u > 1.0. For u < 1.0, add 0.01 ∙ u² to the above factors.

Default value: KA = 1.0.
