Couplings at the input end

Various couplings are used between the motor and the gear unit. The choice often falls on claw couplings or fluid couplings, depending on the application and desired properties.

Compensation of a small axial, radial and angular offset between the two coupling hubs
Elastomers in the coupling connection with their elastic properties ensure damping of shocks and vibrations on the motor side and thus a reduction in the transmission load from the motor
Various designs, e.g. also with brake drum or brake disk

Delay chamber to reduce the motor starting torque for a smooth and safe startup of conveyor systems, bucket elevators or other heavy starting systems
Simple mounting and disassembly (fluid coupling can be removed radially)
Optional monitoring device to detect overheating and stop the system in good time if necessary
various designs, e.g. also with brake drum or brake disk: this enables the use of a brake, low braking torque (as on the input end)

Couplings on the output end

Various coupling types can be used to connect the drive package to the customer's application shaft, depending on customer requirements. These include, in particular, pin, claw, tooth and flange couplings.

Compensation of a small axial, radial and angular offset between the two coupling hubs
Elastomers in the coupling connection with their elastic properties ensure damping of shocks and vibrations on the motor side and thus a reduction in the transmission load from the motor

Compensation of axial, radial and angular misalignment between the two coupling hubs
Elastomers in the coupling connection with their elastic properties ensure damping of shocks and vibrations on the motor side, thus reducing the load on the transmission caused by the motor

Torsional stiffness of the coupling
Compensation of axial, radial and angular misalignment between the two coupling hubs

as a design with keyway connection or cylindrical interference fit
Rigid transmission of forces

Drive packages on steel construction

Swing bases, base frames or customised drive frames offer the option of mounting the drive components on a steel structure in a space-saving and fully assembled manner.

Steel construction for the joint assembly of gear unit, (hydraulic) coupling and motor (and brake if required) including protective equipment such as a bonnet.
Rigid connection to the customer shaft and flexible connection via the torque arm
The torque arm holds the drive package in a horizontal position and prevents rotation of the drive package. All other forces are absorbed via the output shaft.

Steel construction for the joint assembly of gear unit, coupling and motor (and brake if necessary) including protective device, e.g. bonnet.
Rigid connection to the ground
Connection to the customer shaft via a flexible coupling to avoid tension due to static overdetermination
The base frame is designed by SEW-EURODRIVE based on the respective customer specifications. It is designed to absorb the order-specific external forces and torques from the machine and transfer them to the substructure.

Production of customised drive frames according to customer specifications

Brakes

If brakes are to be used on the input end, various designs are possible. In most cases, the choice falls on drum brakes or disk brakes.

Preferably used as a holding brake for the reliable stopping of a conveyor belt, for example: in this example application, the belt is prevented from reversing in idle state.
Monitoring devices for functional tests of the operating state and to prevent incorrect operation
Braking torque can be adjusted over a wide range
Options: automatic wear adjustment, brake open/closed limit switch, manual release lever with safety monitoring

Preferably used as a working brake for reliable braking, e.g. of a conveyor belt over various rotational speeds until idle state is reached
Monitoring devices for functional tests of the operating state and to prevent incorrect operation
Automatic adjustment device for independent equalisation of the brake linings (in the event of wear) for a constant braking torque and to maintain the braking function
Braking torque can be adjusted over a wide range, thus preventing overload from the brake
Precisely timed stopping, e.g. of a conveyor belt with successive belts, thus preventing overfilling of the following belt
Options: automatic wear adjustment, brake open/closed limit switch, manual release lever with safety monitoring

External oil supply and oil cooling systems

Oil cooling systems available as oil-air coolers and oil-water coolers
Oil supply system in which lubrication via a motor pump ensures the oil supply; the motor pump is attached externally to the gear unit and is independent of the speed of the gear unit
Different variants as a combination of oil supply and oil cooling system for supplying and simultaneously cooling (or switching on and off) the gear unit

Almost unlimited increase in thermal ratings
Targeted reduction of the maximum oil bath temperature increases the service life of the oil
Robust gear motor pump
up to starting viscosity of up to 5000 cSt
high availability and flexibility thanks to the use of motors from SEW-EURODRIVE

high availability and flexibility thanks to the use of motors from SEW-EURODRIVE

the motor pump can be switched on independently of the gear unit to ensure sufficient lubrication of the gear unit before starting
well suited for use in connection with inverter operation (gear unit) and for a long start-up ramp (gear unit)
robust gear motor pump
up to a starting viscosity of 5000 cSt
Available with single or double filter

Centralised wiring of sensors to terminal box

All sensors for gearbox monitoring and the sensors of the oil supply system are wired centrally to a predefined terminal box
No local wiring work; simple plug-and-play solution
sensors can be preselected and thus selected as required; the size of the terminal box is determined by the number of sensors installed
Flexible positioning of the terminal box due to spatial characteristics of the application or general customer requirements

Degree of protection IP66 or NEMA 4 in two housing variants for temperatures down to -20 degrees Celsius and -40 degrees Celsius
Three different sizes in painted steel or stainless steel for connecting up to eight sensor technologies; the following dimensions are available:
- 200 x 200 x 100 mm for up to three sensors,
- 300 x 200 x 100 mm for four to six sensors,
- 400 x 200 x 100 mm for seven to eight sensors
