Gearbox range

Modes of operation

On planetary gearboxes, it is possible to use the sun gear, the output shaft or the gearbox housing for power input, output or blocking purposes. Consequently, the admissible speed, the torque and the acceleration torques differ depending on the operating mode. In certain case, torque peaks can combine with high cycling rates to produce undesired vibration in the gearbox.

S1 mode

One speaks of continuous or S1 operation where the gearbox's operating time exceeds 15 minutes without a break or where the duty cycle is greater than 60 %. In no case may the gearbox housing temperature exceed 70° C.

S5 mode

Cyclical or S5 operation is selected where the gearbox's duty cycle is less than 60%. The number of operations per hour can range anywhere from a few to several thousand. If the frequency of start-stop operations exceeds 1000 per hour, the maximum torque occurring must be multiplied by a shock factor to take the additional dynamic loading into account.
