As motor technology is becoming ever more sophisticated and dynamic so is the need for improved gearbox technology to keep pace with developments to help machine builders exploit the benefits of more power and more flexible control. Additionally, in some situations motors are driven to their upper most limits of their capability due to factors such as reduced available space. A good example of this is with AGVs (Automatic Guide Vehicles).
In response to these challenges Dunkermotoren has expanded its range of gearboxes with the PLG 63 HP, PLG 75 HP and PLG 95 HP. These have been specifically developed to provide high nominal torque of up to 160Nm and acceleration torque of up to 320Nm. Among the challenges they focused on is surge loads which can occur in emergency stops, misuse or through vandalism in public-facing applications. Even under the pressures of occasional load peaks of up to 480Nm these new gearboxes remain undamaged and continue to operate normally.
Saving space is often a key objective for machine builders, and these new gearbox options ensure a very compact drive & gearbox system. These planetary gearboxes are designed so that they do not require any coupling or flange to be mounted to the motor, which results in the drive length being reduced to a minimum. When tooth motor shafts are utilised, one-stage gearboxes can be achieved with a reduction ratio of 14, 5:1.
