Abstract
The invention discloses a variable frequency screw catapult for an aircraft carrier. The variable frequency screw catapult comprises a long screw and a nut which is sleeved outside the long screw, wherein the internal threads of the nut are matched with the external threads of the long screw; slide rails are arranged on two sides of the long screw and the nut; a plurality of bearings are uniformly and densely arranged on the upper sides of the slide rails; the long screw is started to rotate by a variable frequency motor; a gear box is connected between the long screw and the variable frequency motor; the variable frequency screw catapult is characterized in that a plurality of in-screw permanent magnet blocks are uniformly distributed in the long screw; corresponding below-screw permanent magnet blocks are arranged at corresponding positions below the long screw and just below the permanent magnet blocks in the screw; the magnetic field directions of the in-screw permanent magnet blocks are reverse to the magnetic field directions of the below-screw permanent magnet blocks; the lower side of a cylinder of the nut is thinner than other parts; and since lateral sliding claws on two sides of the nut which is sleeved outside the long screw are attached to the plurality of bearings on the upper sides of the slide rails on the two sides, the lateral sliding claws can only horizontally slide on the bearings on the two sides.
Description
Technical field
The present invention relates to aircraft carrier frequency conversion screw ejector, be applicable to the take off auxiliary ejector of usefulness of the aircraft carrier-based aircraft cunning formula of jumping, belong to the science and techniques of defence field.
Background technology
The ejector that aircraft carrier-based aircraft takes off is the proprietary technology of the U.S., although " Liaoning number " of China does not adopt ejector, but ejector takes off and can save a large amount of oil plants, thereby can not only strengthen the carrying capacity of carrier-borne aircraft, but also can increase the voyage of carrier-borne aircraft, therefore, the thinking of development shipborne aircraft catapult is forever not have mistake; The present invention provides the ejector that a kind of auxiliary aircraft carriers [later renamed CVE] carrier-borne aircraft cunning formula of jumping is taken off.
Summary of the invention
The purpose of this invention is to provide the aircraft carrier frequency conversion screw ejector that a kind of auxiliary aircraft carriers [later renamed CVE] carrier-borne aircraft cunning formula of jumping is taken off.
Aircraft carrier frequency conversion screw ejector, comprise a long bolt and a nut that is coated on the long bolt, the negative thread of nut and long bolt outside thread are complementary, slide rail is equipped with in long bolt and nut both sides, the even intensive a plurality of bearings that are equipped with of slide rail upside, long bolt starts rotation by variable-frequency motor, is connected with change speed gear box between long bolt and the variable-frequency motor; It is characterized in that:
1, be evenly equipped with permanent magnets in the polylith screw rod in the long bolt, below long bolt with screw rod under the permanent magnets corresponding position permanent magnets below the corresponding screw rod is installed, in the screw rod below the magnetic direction of permanent magnets and the screw rod magnetic direction of permanent magnets opposite; Nut is irregularly shaped, be that the cylindrical downside of nut is thin than other positions, such purpose is to shorten the distance of the interior permanent magnets of screw rod and screw rod below permanent magnets, thereby makes the repulsion energy of same poles of the interior permanent magnets of screw rod and screw rod below permanent magnets hold up long bolt and unlikely buckling.
2, the nut of long bolt outside suit is attached on a plurality of bearings of two wood side-guide upsides because of the sideslip pawl of both sides, so the sideslip pawl can only be done horizontal sliding at a plurality of bearings of both sides; Variable-frequency motor drives long bolt around the rotation of long bolt axle center by change speed gear box, and the rotation of long bolt makes the big nut that is sleeved on the long bolt outside axially do level along long bolt to move around.
3, the sideslip pawl upside of nut both sides is installed two push rods, and push rod can promote aircraft carrier and accelerate to take off; It is consistent with the acceleration/accel that aircraft carrier accelerates needs that the rotative speed that variable-frequency motor is set drives the acceleration/accel that push rod advances, then variable-frequency motor drives the long bolt rotation and drives push rod passing aircraft carrier and accelerates to advance, so just can reduce widely the oil consumption that aircraft carrier takes off, and the charge capacity of aircraft carrier is increased.
4, the booster propulsion set of this Purely mechanical, simple in structure, stable performance, energy consumption are lower, and Non-energy-consumption when aircraft carrier does not take off without free time, can assist aircraft carrier to take off when aircraft carrier takes off at any time.
The present invention compared with prior art has the following advantages:
1, the booster propulsion set of this Purely mechanical, simple in structure, stable performance, energy consumption are lower, and Non-energy-consumption when aircraft carrier does not take off without free time, can assist aircraft carrier to take off when aircraft carrier takes off at any time.
2, the homopolar-repulsion power by permanent magnets in the screw rod and screw rod below permanent magnets holds up long bolt, advances thereby make nut push away fast aircraft carrier under unobstructive state.
Description of drawings
Fig. 1 is the schematic top plan view of the embodiment of the invention;
Fig. 2 is generalized section embodiment illustrated in fig. 1;
Fig. 3 is A-A schematic diagram embodiment illustrated in fig. 1.
Among Fig. 1-3: 1, permanent magnets 11, screw rod below permanent magnets in long bolt 2, slide rail 3, bearing 4, sideslip pawl 5, push rod 6, nut 7, change speed gear box 8, variable-frequency motor 9, negative thread 10, the screw rod.
The specific embodiment
In the embodiment shown in Fig. 1-3: aircraft carrier frequency conversion screw ejector, comprise a long bolt 1 and a nut 6 that is coated on the long bolt 1, the negative thread of nut 6 and long bolt 1 outside thread are complementary, slide rail 2 is equipped with in long bolt 1 and nut 6 both sides, the even intensive a plurality of bearings 3 that are equipped with of slide rail 2 upsides, long bolt 1 starts rotation by variable-frequency motor 8, is connected with change speed gear box 7 between long bolt 1 and the variable-frequency motor 8; It is characterized in that: be evenly equipped with permanent magnets 10 in the polylith screw rod in the long bolt 1, below long bolt 1 with screw rod under the permanent magnets 10 corresponding position permanent magnets 11 below the corresponding screw rod is installed, in the screw rod below the magnetic direction of permanent magnets 10 and the screw rod magnetic direction of permanent magnets 11 opposite; Nut 6 is irregularly shaped, be that nut 6 cylindrical downsides are thin than other positions, such purpose is to shorten the distance of permanent magnets 10 and screw rod below permanent magnets 11 in the screw rod, and the repulsion energy of same poles of permanent magnets 10 and screw rod below permanent magnets 11 holds up long bolt 1 and unlikely buckling in the screw rod thereby make.
The nut 6 of long bolt 1 outside suit is attached on a plurality of bearings 3 of two wood side-guides, 2 upsides because of the sideslip pawl 4 of both sides, so sideslip pawl 4 can only be done horizontal sliding at a plurality of bearings 3 of both sides; Variable-frequency motor 8 drives long bolts 1 around the rotation of long bolt 1 axle center by change speed gear box 7, and the rotation of long bolt 1 makes the nut 6 that is sleeved on long bolt 1 outside axially do level along long bolt 1 to move around.
The specific embodiment is: nut 6 is pasting aircraft carrier near motor position by push rod 5 tops of nut 6, when variable-frequency motor 8 starts, aircraft carrier also starts simultaneously, along with the acceleration of aircraft carrier is advanced, the push rod 5 on variable-frequency motor 8 drive long bolts, 1 rotation and the drive nut 6 promotes at a high speed aircraft carrier and accelerates to advance.
