Twingear
The KS TwinGear bevel helical gear is a high performance, precise gear. Thanks to its slimline construction, this two-stage gearbox performs very well in any application, with transmission ratios of up to 75:1. The KS TwinGear’s high torsional stiffness and the low backlash ensure accurate transmission.
Its main features are:
Nominal torque on the output of up to 7500 Nm.
Transmission ratios of i=15:1 to i=75:1.
Suitable for high drive speeds.
Can be mounted directly on the motor or by using a coupling.
High torsional stiffness.
Particularly low noise.
Compact design.
