Lenze Clutches & Brakes
Brakes and couplings/clutches
Cater for changing mass movements
Spring-applied brakes with electromagnetic release are used to rapidly decelerate or hold moving masses in a controlled manner.
Compression springs provide the braking force, meaning that the friction-generated torque is still available even when no current is flowing - including in the event of a mains failure.
Electromagnetic clutches and brakes and clutch/brake combinations
Electromagnetic clutches and brakes are used to quickly brake or accelerate moving masses.They are also available as a clutch/brake combination unit in a single housing. These combinations are predominantly used in cyclical production processes. The torque is generated by the friction during a dry run and under voltage. The lock ring assures there is no residual torque after being switched off.
Tooth clutches and gear brakes
Tooth clutches and gear brakes transfer high to very high torque through mechanical locking. A DC voltage causes the teeth to interlock and should only be used at lower speeds.
Further couplings and clutches
Couplings and clutches are used in the torque transmission of engageable and disengageable connections between shafts and flanges. Our comprehensive range optimally compensates for shaft misalignments (radial, axial and angular differences). Our range is completed by friction-fit and positive-fit overload element designs.
