Embodiment
Execution mode of the present utility model is illustrated below in conjunction with accompanying drawing.
As shown in the figure, a kind of phase shifter transmission device, is provided with at least two worm gears be arranged in a linear 4, and each worm gear 4 is all connected with phase shifter.The embodiment of Fig. 1 is the execution mode of control 6 phase shifters, in order to demonstrate the locking device at worm gear rear portion, eliminates one of them worm gear in figure.The drive rod 5 and screw rod 6 that can control respectively to rotate is provided with along worm gear 4 orientation.Drive rod 5 and screw rod 6 are parallel to each other, and are arranged on together in a housing in worm gear 4.Drive rod 5 is provided with one to slide but the worm screw 3 that can not relatively rotate along it.In order to ensure smooth motion, the centre bore cross section of described worm screw 3 is identical with the cross section of drive rod 5.Any applicable mode can be adopted to rotate to ensure that worm screw 3 and drive rod 5 are not relative, and such as worm screw and drive rod are located by the projection that matches and groove (key or keyway) circumference.Screw rod 6 is provided with a plectrum be threaded with it 2, and described worm screw 3 connects with plectrum 2.Plectrum 2 is provided with the internal thread coordinated with screw rod 6, when screw rod 6 rotates, plectrum 2 limits owing to being subject to worm screw 3 and can not rotating, thus plectrum 2 can be made to move left and right along it by rotating screw bolt 6, thus worm screw 3 can be slided to engage from different worm gears 4 along drive rod 5 under the drive of plectrum 2.Plectrum 2 can be made while drive worm screw 3 not affect it by any feasible mode to rotate.Such as on plectrum 2, arrange bearing, the end of worm screw 3 is placed in bearing.Or as shown in Figure 4,5, be arranged to the end of worm screw 3 in ladder shaft-like, one end of plectrum 2 coordinates with the shaft shoulder portion of this multidiameter.Further, one end of plectrum 2 can be arranged to have half-terete opening, this opening coordinates with the shaft shoulder portion of worm screw 3 end multidiameter.
To engage with one of them worm gear 4 when worm screw 3 slides into and after stopping, worm gear 4 can be driven to rotate by rotary worm 3, and then corresponding phase shifter is adjusted.When selecting the worm gear 4 that will adjust, worm screw 3 usually will through several worm gear not needing to adjust.In order to make worm screw 3 by time interference is not produced to these worm gears without the need to adjustment, can by controlling the rotating speed of drive rod 5 and screw rod 6, worm screw 3 is often rotated tooth pitch that the distance of sliding along drive rod 5 for a week equals worm screw 3.Its principle is, when supposing the static engagement of worm and wheel, the worm screw worm gear that often turns around turns over a tooth, i.e. worm and gear relative displacement tooth pitch P1, if make worm screw move a distance P1 in the other direction, then worm gear can keep transfixion, thus worm screw can realize by any worm gear and not produce interference.The distance of worm screw movement can be controlled in the following way.First kind of way: be P1 by designing the pitch of drive screw 6, drive screw 6 turns around, and worm screw is moved as P1.The second way: if drive screw 6 pitch is not equal to P1, then by adjustment stepping motor rotating speed, make worm screw amount of movement be P1.
When not adjusting phase shifter, in order to prevent worm gear wheel, all configure a locking device can to each worm gear, this locking device has a spring 8 and one can insert latch segment 7 in locking hole that worm gear 4 end face is arranged under spring 8 acts on.The shape of latch segment and locking hole can be arranged as required, as long as can realize its function, the locking hole of the circular hole that is such as circularly and evenly distributed on worm gear end face, latch segment arranges protrusion, can insert the cylindrical bump in locking hole.Further, be provided with lead-in chamfered 9 in the both sides of described latch segment 7, plectrum 2 can by this lead-in chamfered extruding latch segment 7, and make it exit locking hole in moving process.Thus when making worm movement to the position of engaging with worm gear, corresponding worm gear automatic unlocking.Described locking device also can arrange for guiding the reciprocating axis of guide of latch segment 7, to ensure its precise movement.
In transmission device of the present utility model, drive rod 5 and screw rod 6 only need be configured for the control driving its motor rotated can realize multiple phase shifter respectively.Give the embodiment of control 6 phase shifters shown in Fig. 1, Fig. 2, according to actual needs, also can arrange 5,8, even more phase shifters.
