Abstract
A driving device for adjusting an activating element of a throttle, of a valve, of a connecting device, of a metering device or the like in particular in the field of oil and gas exploration with at least one rotary gear movably connected to the activating element and a gear arranged between the rotary gear and at least one motor. To improve such a drive device in that the structure is simple and compact and efficiency is increased wherein simultaneously high axial forces are avoided and only a small number of assembly parts are necessary, the gear unit comprises a reduction gear assigned to the rotary gear in particular the so called harmonic drive gear, and a spare gear assigned to the motor which is in particular self locking.
Claims23
Drive device for the adjustment of an actuating element of a throttle, valve, connection device, or dosage feed device in the production of oil or gas, the drive device comprising:
- a circulation body having fluid flow therethrough;
- at least one spindle drive disposed within the circulation body and movably connected to the actuating element to adjust the fluid flow therethrough;
- a gear unit disposed within the circulation body and arranged between the spindle drive and at least one motor disposed within the circulation body;
- the gear unit including a reduction gear connected to the spindle drive, and a spur gear having a first spur gear wheel directly connected to the reduction gear and a second spur gear wheel connected to the motor wherein a helix angle of the tooth arrangement of the first and/or second spur gear wheel lies in the range from 65° to 85°.
