Description
Brand - RINGSPANN
Part Number - IR 12 R RINGSPANN
Category - Irreversible Locks IR (Standard Type R)
Principal Dimensions & Specifications (Metric):
Bore Diameter (d) - 12 mm
Dimension (A)* - 13.8 mm
Dimension (B)* - 4 mm
Dimension (C) - 2.2 mm
Dimension (D) - 42 mm
Dimension (E) - 11.2 mm
Thread (G)** - M4
Dimension (L) - 17.7 mm
Dimension (M1) - 24 mm
Dimension (N) - 12 mm
Dimension (O) - 8 mm
Dimension (P) - 9.5 mm
Dimension (Q) - 5 mm
Dimension (R) - 5.5 mm
Dimension (T)** - 26 mm
Dimension (V) - 5.7 mm
Number of Tapped Holes (Z)** - 3 mm
Weight - 0.15 kg
Type - Standard Type for Universal Use
Nominal Torque (MN) - 8 Nm
Description of Suffix:
R - Standard Type for Universal Use
Other salient points to be noted:
• The maximum transmissible torque is 2 times the specified nominal torque
• Bidirectional acting backstop for assembly with connecting parts with rollers
* Keyway according to DIN 6885
** Z - Number of tapped holes G on pitch circle T
Features:
• Irreversible Locks IR are bidirectional acting roller freewheels with integrated bearing support
• Capable of handling nominal torques up to 100 Nm
• Available with bores up to 35 mm
Application as: Bidirectional Acting Backstop
Application Example:
• The Irreversible Lock prevents any uncontrolled movement of the valve caused by pressure from the flowing medium in the pipeline
• In motorised applications, the main benefit is that the torque motor only needs to provide the adjusting torque (typically low), as the Irreversible Lock absorbs all standing and sudden reverse torques
Operation:
• The system is symmetrical, so this operation works the same way in both rotational directions
• If external forces from the machine attempt to rotate the centre body (via the shaft), the centre body is locked to the fixed housing by the locking rollers
• The irreversible lock prevents unintended shifts or displacements from occurring
