R, F, K gear units Depending on the number of gear stages, the gearing efficiency of helical, parallelshaft and helical-bevel gear units is up to 96% (3-stage), 97% (2-stage) and 98% (1- stage).

Type designation of a DRN.. gearmotor

The type designation of the gearmotor starts from the component on the output endFor instance, a multi-stage helical-bevel gearmotor with temperature sensor in the mo-tor winding has the following type designation:

Example: K107R77 DRN100LS4 /TF
Gear unit type	K	1st Gear unit
Size	107	1st Gear unit
Gear unit type	R	2nd Gear unit
Size	77	2nd Gear unit
Motor series	DR	Motor
Product line	N
Size	100LS
Number of poles	4
Motor option temperature sensor	/TF	Option

The desians described in this chapter refer to DRN..gearmotors from SEW-EURODRlVE.They also apply to gear units without motors
