Title: Linear driving device with two motors
Inventor: FICKLER HANS
IPC: F16H25/20
Filed: 1984-04-30
Granted: 1988-02-11
Abstract: The linear feed device is suitable for extremely slow feed rates or extremely small feed steps. It works with two motors (M1, M2) which drive a nut (16) and a screw spindle (2) via an intermediate drive (12-15; 22-25). The intermediate drives have slightly different transmission ratios, e.g., 1:0.340909 and 1:0.3414634.
