DLB Make choice:
OUTPUT TORQUE
Rated output torque
Mn2 [Nm]
The torque that can be transmitted continuously through the output
shaft, with the gear unit operated under a service factor fs = 1.
Required torque
Mr2 [Nm]
The torque demand based on application requirement. It is
recommended to be equal to or less than torque Mn2 the gearbox under
study is rated for.
Calculated torque
Mc2 [Nm]
Computational torque value to be used when selecting the gearbox.
It is calculated considering the required torque Mr2 and service factor fs,
as per the relationship here after:
POWER
Rated input power
Pn1 [kW]
The parameter can be found in the gearbox rating charts and represents
the KW that can be safely transmitted to the gearbox, based on input
speed n1 and service factor fs= 1
Rated output power
Pn2 [kW]
This value is the power transmitted at gearbox output. it can be
calculated with the following formulas:
EFFICIENCY
Dynamic effciency
[ηd]
The dynamic efficiency is the relationship of power delivered at output
shaft P2 to power applied at input shaft P1:
Static effciency
[ηs]
Effciency obtained at start-up of the gearbox. Although this is generally
not significant factor for helical gears, it may be instead critical when
selecting worm gearmotors operating under intermittent duty
