4. Set-up of gear unit / technical data
4.1 Set-up of gear unit
DynaGear
are angular gear units with case-hardened bevel gear pairs with Gleason hypoid toothing,
for installation in machines and systems. In terms of performance capability, DynaGear matches all common
servo motors and can be adapted variably via flange and coupling. The gearboxes have optimum centring on
the mounting sides 1 and 3 and machined sides 4 and 5 with mounting threads. The shafts are supported by
taper roller bearings in cantilevered support (input) and forked mounting (output), shaft seal rings made of NBR
(ni
trile rubber ‘Buna’) and FKM (fluorocarbon ‘Viton’); flange seals by lamella sealing discs.
Ratios mathematically accurate from 3.00:1 to 15.00:1. Gearboxes in solid shaft or hollow shaft design,
for clutch transmission or direct mounting of the motor.
DynaGear
gear units are in full compliance with the machine directives (EN 292) and EMC directives to the
extent they are applicable.
4.2 Type designations
DynaGear D37 to D190
Output in solid shaft (build types 1L, 3L and 13L) and hollow shaft design 1LSV and 3LSV without
motor lantern and without coupling
Output in solid shaft (build types 1L, 3L and 13L) and hollow shaft design 1LSV and 3 LSV with motor
lantern and coupling
Type: L Series (solid shaft)
Shown in ratio 8:1 and in a shaft arrangement 1L, with 1
output shaft on side 1, on the drive side complete with mo-
tor lantern and metal bellow-type coupling. Additional shaft
arrangements on the output are 3L and 13L
Type: H Series (hollow shaft)
Shown in ratio 8:1 and in shaft arrangement 1LSV with shrink
disk seat on side 3. Further shaft arrangements are 3LSV and
13LSV. The extension of the hollow shaft for the shrink disk is
respectively situated opposite the attachment side.
The bearings are designed with tapered roller bearings. In the case of the ratios 3:1 and 5:1, the drive pinions are designed
as pinion shafts, from ratio 6:1 the drive pinions are shrunk into the drive shaft.
The output-side bevel gears are shrunk onto the output shafts.
