Abstract
For a forcer for hydraulic-driven thrust stand, relate to a kind of force actuators. It comprises hydraulic cylinder, the first auricle, binaural connector, the second auricle; Described hydraulic cylinder is fixed on ground, and the pressure output end of hydraulic cylinder is fixedly connected with the first auricle, and the first auricle and the second auricle are positioned at same vertical guide, has two connecting holes on ears brace, is connected for realizing pin with the first auricle and the second auricle respectively; Hydraulic cylinder produces thrust, and thrust passes to the second auricle by the first auricle, and the second auricle is connected with external equipment, and power is transmitted on external equipment. The present invention can produce 50T magnitude high thrust, and measures good reliability, and precision is high.
Description
Technical field
The present invention relates to a kind of force actuators, particularly relate to the power for hydraulic-driven thrust standGenerator.
Background technology
More existing engine testsand thrust stand adopts motor to drive and produces thrust, because space hasThe acc power of rationing the power supply is less cannot meet the demands.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, provide a kind of hydraulic pressure to driveDynamicthrust stand forcer, can produce compared with high thrust, measures good reliability, and precision is high.
Technical solution of the present invention is: a kind of forcer for hydraulic-driven thrust stand,Comprise hydraulic cylinder, the first auricle, binaural connector, the second auricle; Described hydraulic cylinder is fixed on ground,The pressure output end of hydraulic cylinder is fixedly connected with the first auricle, and the first auricle and the second auricle are positioned at sameVertical guide, has two connecting holes on binaural connector, for respectively with the first auricle and the second auricleRealizing pin connects; Hydraulic cylinder produces thrust, and thrust passes to the second auricle by the first auricle, the second earSheet is connected with external equipment, and power is transmitted on external equipment.
Described the first auricle is identical with the shape of the second auricle, and one end is rectangle, and the other end is semicircle,The scope of the length-width ratio of described rectangle is 1.25-1.5.
The material of described the first auricle and the second auricle is No. 45 steel through modifier treatment.
The present invention compared with prior art beneficial effect is:
(1) motion mode that the present invention is directed to hydraulic cylinder has designed corresponding forcer, can produceThe thrust of 50T magnitude, has broken through the less thrust that causes of available engine test bay power of motor limitedPredicament;
(2) the present invention has designed the transmission system being made up of two auricles and binaural connector, two earsSheet can expansion force generator conduction distance, two auricles are positioned at same vertical guide simultaneously, have avoidedBecause of the downward component that the gravity of auricle produces at connector place, improved power conduction uniformity andValidity.
(3) the present invention, by choosing the material of auricle, the dimensional parameters of design auricle, has ensured holdingWhile being subject to the thrust of 50T magnitude, transmission system distortion is no more than 2 ‰, avoids the measurement producing due to distortionError.
(4) mounting means of the present invention is simple, is easy to promote, and is applicable to the examination of aerospace field engineRide thrust stand, has improved Aero-Space power technology test condition.
Brief description of the drawings
Fig. 1 structural representation of the present invention.
Detailed description of the invention
The motion mode that the present invention is directed to hydraulic cylinder 1 has designed corresponding forcer, can produce 50TThe thrust of magnitude, has broken through that available engine test bay power of motor is less causes the limited predicament of thrust,Improve Aero-Space power technology test condition.
As shown in Figure 1, the present invention includes hydraulic cylinder 1, the first auricle 2, binaural connector 3, secondAuricle 4; Described hydraulic cylinder 1 is positioned on hydraulic mount 7, and hydraulic mount 7 is fixed on ground, hydraulic pressureThe pressure output end of cylinder 1 is fixedly connected with the first auricle 2. The first auricle 2, the second auricle 4 and twoEar connector 3 forms transmission system, the conduction distance that two auricles can expansion force generator. EarsOn connector, have two connecting holes, connect for realizing pin with the first auricle 2 and the second auricle 4 respectivelyConnect. Such connection limit method mounting means is simple, is easy in aerospace field extensive use.
The first auricle 2 is identical with the shape of the second auricle 4, and one end is rectangle, and the other end is semicircle,The scope of the length-width ratio of described rectangle is 1.25-1.5. The material of the first auricle 2 and the second auricle 4 is equalFor No. 45 steel through modifier treatment. Such structural design and material are selected, and have ensured bearingWhen the thrust of 50T magnitude, transmission system distortion is no more than 2 ‰, avoids the measurement mistake producing due to distortionPoor. The first auricle 2 and the second auricle 4 are positioned at same vertical guide, avoid connecting because of the gravity of auricleThe downward component that fitting place produces, uniformity and the validity of the conduction of raising power.
Hydraulic cylinder 1 produces thrust, and thrust passes to the second auricle 4, the second auricles by the first auricle 24 are connected with external equipment, and power is transmitted on external equipment. External equipment can be power sensor 5Deng. Shown in Fig. 1, be the second auricle 4 and be connected with power sensor 5, power sensor 5 is fixed on biographyOn sense bearing 6, sensing bearing 6 is fixed on thrust stand.
The content not being described in detail in description of the present invention belongs to those skilled in the art's known technology.
