Description of drawings
Fig. 1 is the structural representation of mechanical type distance adjustor.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of mechanical type distance adjustor, comprise drive motor 1, feedback rod 2 and pull bar 3, the output shaft of described drive motor 1 is connected with an end of screw set 4, the other end of described screw set 4 is installed on the auxiliary bearing seat 5, described screw set 4 middle parts are provided with outside thread, described outside thread and 6 engagements of leading screw bar, described leading screw bar 6 is captiveed joint with main bearing seat 7, described main bearing seat 7 interior installation feedback rods 2, described feedback rod 2 is captiveed joint with pull bar 3, and described feedback rod 2 is with pull bar 3 and is arranged vertically.
Further, linear displacement transducer 8 is installed on the described main bearing seat 7.
Further, the two ends of described feedback rod 2 are connected with feedback loop 9 respectively, and described feedback loop 9 is installed in the described main bearing seat 7 by thrust baring 10.
The output shaft of described drive motor is connected with drop-gear box, and described drop-gear box is connected with described screw set, on the described drop-gear box handwheel is installed.Described handwheel adopts the disengaging type mounting structure, and when drive motor was worked, handwheel did not rotate; In the dead electricity situation, handwheel can drive realizes manual roll adjustment.
At first, system's roll adjustment propulsion source is drive motor 1, by the rotation of driven by motor drop-gear box 13, drive the rotation of screw rod bushing 6, thereby drive the movement of distance adjustor, drive moving forward and backward of pull bar 3 by feedback rod 2, the drive saddle moves, thereby realizes this change of pitch of propeller.Schematic diagram as shown in Figure 1.
Motor reducer is fixed on the hull, tooth bar and built-in bearing all are fixed on the Connection Block of hull, the screw mandrel rotation that links to each other with motor output end, extraordinary circumstances occurring at motor can't normally use, and the rotation of emergent handwheel drives the rotation of the output shaft of drop-gear box, and then drives the rotation of screw rod bushing, then driving driven tooth bar moves axially, tooth bar cooperates with the Connection Block overcoat, and the bearing mobile restriction in the Connection Block is lived feedback board, guarantees that the roll adjustment pull bar axially moves in the same way with tooth bar.
In the design, the advantage by Gear Transmission Design is, by the deceleration of gear, can be more laborsaving, and directly come transmitting torque by screw mandrel, make whole system not only laborsaving but also efficient.And the processing of tooth bar is simple, easy to maintenance, cost performance is high.
In whole roll adjustment process, axle system rotates, in order to solve the Rotation of distance adjustor, increased the design of bearing in the system, the outside at feedback loop, support bearing by the cylindrical of feedback loop and the inner circle of screw mandrel inner sleeve, bearing can solve the puzzlement that distance adjustor rotates together along with axle in the roll adjustment process, keeps balance not rotate; In addition, in the roll adjustment process, the problem of axially loaded is selected cylindrical roller bearing, and it can bear axial force, power is directly passed to feedback loop acts on the pull bar through feedback rod, finishes the roll adjustment process.
Whole system is grease lubrication, and each connecting portion has used sealing arrangement, guarantees that bearing can both be lubricated all the time, prolongs to the full extent the service life of bearing.
The design of linear displacement transducer is worth mentioning very much in addition, in the system that entirely is mechanical type mechanism, in order to guarantee the accuracy of system's roll adjustment, it is very significant designing such positioner, whole system improves Systems balanth and reliability by reducing with highly sensitive hydraulic unit, the use of linear position sensors has guaranteed the roll adjustment precision of system simultaneously, really is not only to have guaranteed the precision of system but also improved reliability and stability.
The labile factor of the mechanical type tuning for Controllable Pitch Propeller of present embodiment in can the minimizing system, increase Systems balanth, replaced original hydraulic distance-regulating system with the roll adjustment of Purely mechanical, Systems balanth is stronger, and in addition from cost performance, mechanical distance adjustor cost performance is higher, reduced the use of precision parts, on the cost greatly the reduction of degree cost, can be that more user can afford to use, and tuning for Controllable Pitch Propeller road-holding property more flexible.
For the labile factor in the minimizing system, increase Systems balanth, we have replaced original hydraulic distance-regulating system with the roll adjustment of motor band Purely mechanical in current invention process, Systems balanth is stronger, propulsion source is the driven by motor drop-gear box, by lead screw transmission mechanism, thereby drive moving forward and backward of pull bar.
From cost performance, mechanical distance adjustor cost performance is higher, has reduced the use of precision parts in addition, on the cost greatly the reduction of degree cost, can be that more user can afford to use, and tuning for Controllable Pitch Propeller road-holding property more flexible.
