Applications for Planetary Epicyclic Drives

Two or More Speeds:

This permits a high speed for production (ratio 1:1) and a low speed for adjustment (ratio 1/K).

Two Speeds by Direct Mesh

High-Speed	Neutral	Low Speed
N1=N2=N3	N3=0	N2=0   N3=N1/K
The Torque Arm Sleeve (2) is attached to the Case (1)	Torque Arm Sleeve (2) turns freely	Torque Arm Sleeve (2) is attached to the machine frame

Since the gears do not rotate in ratio 1:1 (solid pulley drive), the Planetary Epicyclic Drive can be selected based on the low-speed (1/K) parameters.

Several Speeds:

It is often necessary to drive machine tool feed mechanisms with a high-speed approach, a low-speed, high torque working feed, and a high-speed return (transfer feed table, carriage, etc.).  It is possible to combine the Planetary Epicyclic Drive with two motors to achieve this combination of speeds.

The reduction ratio K is chosen according to the application requirement (-1 to 260).

Other Applications:

• Reducer/Increaser
• Phase-Shifting
• Precise Speed Adjustment
• Creation of a Relative Speed While Running
• Cyclic Synchronization of Two Speeds
• Timing Movements
• Balance Speed & Torque
