Geislinger Coupling, Flexlink and SAE

Product Description

Torsional elastic steel spring couplings:
Example of coupling designation: BC 90/15/75 N
- BC: type of connection flanges
- 90: outer diamter of centre part in [cm]
- 15: width of spring pack in [cm]
- 75: stiffness series and approximate twist in [mrad] at nominal torque
- N: blade design:
- Type N, NC, NCS, NC3: non-reversible version with unsymmetric spring arrangement
- Type H, HC, HCS, HC3: semi-reversible version (can transmit 0,5 x nominal torque in reverse direction)
- Type U, UC, UCS, UC3: reversible version with symmetric spring arrangement
Where C in the above designations means that conical blade design is used.
Flexlink is a torsional rigid and bending compliant steel coupling (to compensate for axial-, angular- and, in dual version, radial shaft misalignment) consisting of tangentially arranged links.
Example of coupling designation: GFL S 63 F 8A
- GFL: Geislinger FlexLink
- S: series
- 63: size
- F: type
- 8: number of links
- A: axial support
Geislinger SAE-Couplings are torsional elastic oil filled steel spring couplings.
Example of coupling designation SE 41/2.2/120NC3/20/S14/L
- SE: SAE-type of engine flywheel. Inner connection of the coupling is a standardized spline connection. Different adaptors fitting to the spline connection are available on request.
41: Outer diameter of centre part in cm
2.2: Spring pack width in cm
120: Stiffness series and the approximate twist in mrad at nominal torque.
Standard series are 30, 60, 90 and 120.
Torsional stiffness and nominal torque can be varied by different number of spring packs.
NC3, UC3: Directionality code for coupling type with 3-spring design
NC3 non-reversible
UC3 reversible
20: Number of spring packs per coupling (8, 10, 12, 14, 15, 16, 18 or 20)
S14: Connection fitting for SAE-flywheel
S14 : fitting for SAE-flywheel size 14 (flange drillings for SAE- inch bolts)
M14 : fitting for SAE-flywheel size 14 (without flange drillings)
L: Left hand coupling rotation when looking to the side plate, if torque input from coupling outer part.
R: Right hand coupling rotation when looking to the side plate, if torque input from inner star.
1/L: Left hand coupling rotation when looking to the side plate, if torque input from inner star.
1/R: Right hand coupling rotation when looking to the side plate, if torque input from coupling outer part.
SB: SAE-type of engine flywheel. The SB-Coupling with its innerstar fixation is always combined with the Gesilco? BF-Coupling connecting to a customized flange hub.
