Rollers Torque Limiter DSR
Safety coupling with the transmission of motion through rollers that allow complete disengagement when the calibrated torque is reached permitting a quick stop of the transmission due to micro-EM1. Suitable for transmitting high torque with high reliability and compact size.
- Precise torque setting by adjusting the radially balanced locking nut;
- The innovative regulation of the nominal torque by measuring the “H” dimension allows for immediate coupling calibration.
- Equidistant re-engagement in phase or at 360°;
- Available with electromechanical switch / proximity for the transmission disconnection;
- Immediate intervention for an improved reaction compared to electronic systems;
- Maintenance-free for long lasting high reliability;
- Suitable for oily and wet environments.
- Complete with transmission gear, fully turned and mounted (plate wheel, pulley, gear pair);
- Possibility to use helical springs for low intervention torques;
- Connections with bore and keyway, locking assembly possible;
- Version with personalized re-engagement in phase 36°, 45°, 60°, 90°, 120°, … possible.
- Packaging and wrapping machines;
- Labeling machines;
- Bottling machines;
- Conveyors.
- Protects the gearbox from jamming due to foreign matters;
- Protects packages from squashing and deforming;
- Protects the product handling elements from accumulations;
- Maintains the timing between driver and driven after an overload.
