Metal Bellows Couplings
Rimtec zero-backlash couplings provide servo-quality stiffness and low
inertia for highly dynamic servo and vector drives, but without the
misalignment problems that are common with traditional metal bellows
couplings.
This high-performance line incorporates a unique taper lock design,
which self-centres the motor shaft when assembled, and self-loosens to
easily release when disassembled.
Compared to ordinary taper locks, this special clamping style is
extremely cost effective in conjunction with Rimtec high-end couplings
– it achieves highly accurate manufacturing tolerances, dramatically
reduces bearing wear, slashes downtime, and practically eliminates the
need to inventory replacement drives.
Metal bellows couplings transmit torque from 159.3 lb-in (18 Nm) to
44,250 lb-in (5000 Nm), on shaft sizes from .04 inches (1 mm) up to 4
inches (100 mm).
Advantages
- Zero backlash, high stiffness and low inertia
- Compensates for heat, pressure & elastic deformation that commonly
cause axial, radial and angular misalignment
- Maintenance free - built to last
- Efficient and smooth power transmission
- Reliability, precision, power and repeatability integrated in each
unit
Applications
- High-production transfer lines
- Robot’s ball screw slides and gearboxes
- CNC machine tool
- Packaging machines
- Printing presses
- Any other manufacturing with high rotational speeds and high torque
