Abstract
The utility model discloses a kind of aircraft hold PDU rubber roll testing stands for belonging to airborne attachment test device.Fix lifting platform, the support column of roller, gearbox, torque sensor and magnetic hysteresis dynamometer machine successively on aircraft hold PDU rubber roll bed stands；For cylinder support right over lifting platform, lifting platform, which is fixed, is tested PDU rubber rolls, and PDU rubber rolls are lifted and withstood on roller upwards by rubber roll, applies normal pressure for PDU idler wheels.When PDU rubber rolls work, PDU rubber rolls drive roller rotation.Magnetic hysteresis dynamometer machine provides torque loads for system, and tested PDU rubber rolls are passed to by gearbox, roller.With torque formula, the drawing force of PDU rubber rolls generation is calculated.This testboard solves the problems, such as to cause abrasion to tested PDU rubber rolls when the test of genuine equipment, while avoiding injury of the test noise to tester.
Description
Technical field
The utility model belongs to the test device of airborne attachment, more particularly to a kind of aircraft hold PDU rubber rolls
Testing stand.
Background technology
The main-line-aircraft that civil aviaton of China uses at present is all the Air Passenger of external import, Boeing series, and installation attachment is also
It is produced by external producer.Repairing data, equipment, equipment needed for airborne attachment etc. need to all purchase from genuine, there are it is time-consuming, take
The drawbacks such as power, at high price.Genuine equipment equally exists defect in its design, manufacturing process simultaneously, has much room for improvement.Genuine carries
The loading method of confession is when PDU (brand) rubber roll works, and one flat plate is pressed in top, using PDU rubber rolls in tablet
Upper to skid so that tablet generates forward pulling force, the pull pressure sensor monitoring PDU rubber rolls installed below by tablet skid
The drawing force of generation.PDU rubber rolls are constantly in slipping state on tablet when due to test, so easily rubber is caused to roll
Foot wheel abrasion causes unnecessary economic loss.Meanwhile rubber roll can send out sharp noise when skidding on tablet, to surveying
The health of examination personnel causes harmful effect.The utility model converts sliding test to rotation test, utilizes torque loads
The drawing force of PDU rubber rolls is obtained by the method for calculating.Test PDU rubber rolls do not generate relatively sliding with test roller
It is dynamic, the possibility of abrasion rubber roll is thus greatly reduced, economic loss is reduced.Rubber roll is opposite with test roller simultaneously
It rolls, squeal-noise caused by opposite sliding will not be formed, tester will not be damaged.
Utility model content
The purpose of this utility model is that there are drawbacks for the attachment test method of external import aircraft, after solving to repair
Testing requirement, propose a kind of aircraft hold PDU rubber roll testing stands to substitute the genuine equipment of import, feature exists
In, on aircraft hold PDU rubber rolls bed stand 1 successively fix lifting platform 3, the support column of roller 5, gearbox
6, torque sensor 7 and magnetic hysteresis dynamometer machine 8；Roller 5 is supported on right over lifting platform 3, and pull pressure sensor 2 is mounted on can
The lower section of hoistable platform 3, wheel speed sensors 4 are mounted in the support column crown of 5 one end of roller, and with 5 circumference contact of roller, gearbox
6 are combined with the support column of 5 other end of roller；Gearbox 6, torque sensor 7 are connected with magnetic hysteresis dynamometer machine 8；It then will be by
PDU rubber rolls are surveyed to be fixedly mounted on lifting platform 3 by screw.
The lifting platform 3 lifts PDU rubber rolls upwards, with 5 circumference contact of roller.
The utility model has the beneficial effects that significantly reduce PDU rubber rolls there is the possibility worn in test,
Economic loss is reduced, while avoiding generating slip noise, avoids causing personal injury to tester.
Description of the drawings
Fig. 1 is the test platform structure schematic diagram of aircraft hold PDU.
Specific implementation mode
The utility model proposes a kind of aircraft hold PDU rubber roll testing stands, are explained below in conjunction with the accompanying drawings.Flying
Lifting platform 3, the support column of roller 5, gearbox 6, torque are fixed on machine cargo hold PDU rubber rolls bed stand 1 successively
Sensor 7 and magnetic hysteresis dynamometer machine 8；Roller 5 is supported on right over lifting platform 3, and pull pressure sensor 2 is flat mounted on liftable
The lower section of platform 3, wheel speed sensors 4 are mounted in the support column crown of 5 one end of roller, and with 5 circumference contact of roller, gearbox 6 and rolling
The support column of 5 other ends of cylinder is combined；Gearbox 6, torque sensor 7 are connected with magnetic hysteresis dynamometer machine 8；Then by tested PDU
Rubber roll is fixedly mounted on by screw on lifting platform 3.
Operation principle：When experiment, lifting platform 3 lifts PDUPDU rubber rolls upwards, makes to connect with 5 periphery of roller
It touches.And the normal pressure that rubber roll is born is monitored by the pull pressure sensor 2 mounted on 3 lower section of lifting platform.PDU rubber
When idler wheel works, the rotation of PDU rubber rolls drives roller 5 to rotate together, and without opposite sliding.The monitoring rolling of wheel speed sensors 4
The rotation of cylinder 5 and the rotation linear velocity for feeding back roller 5.Due to being slided without opposite between PDU rubber rolls and roller 5, so
The rotation linear velocity monitored is the linear velocity of PDU rubber rolls.Roller 5 passes through gearbox 6, torque sensor 7 and magnetic hysteresis
Dynamometer machine 8 connects, and magnetic hysteresis dynamometer machine 8 provides required load resistance for test PDU rubber rolls.It is supervised by torque sensor 7
Mechanical relation between each component of load torque and testing stand measured can calculate dragging caused by PDU rubber rolls
Power, the i.e. test result of cargo hold PDU rubber rolls.
