Version: 2.5
Below you will find definitions of terms, environmental conditions,
operating details and technical data for the planetary gear units.
When attaching a gear unit, the performance may be reduced by up
to 20 %. The flange of the motor used for heat dissipation is fitted
with a gear unit that generates heat during operation. The power de-
rating therefore has thermal reasons.
This chapter provides information on various technical terms and
their meaning.
Equivalent force on the output F
The equivalent force on the output describes the force that is rele-
vant for dimensioning the gear unit.
Equivalent application torque T
The equivalent application torque describes the torque that is rele-
vant for the dimensioning of the gear unit.
Dimensioning factor f
a
The dimensioning factor describes the influence of the daily operat-
ing time and the operating factor on the application torque.
Operating mode factor K
The operating mode factor describes the influence of duty cycle,
number of cycles and dynamics on the application torque.
Mass moment of inertia; based on the drive J
The mass moment of inertia is a measure for the tendency of a body
to maintain its motion state (whether at rest or in motion).
Running noise L
[dB/A]
PA
The running noises are influenced, for example, by:
• transmission ratio and speed
• lubricants and gearing or
• Installation position
