Abstract
Provided is a cylindrical gearbox mechanical closed test bench suitable for any center distance. If any of a model of a motor, operation speed and a wheel diameter of a gearbox is different from that of another gear box, the models or transmission ratios of the gearboxes are different and accordingly center distances of the gearboxes are different; different connection gearboxes are needed in order to test the gearboxes with different cylindrical gear center distances. The mechanical closed test bench of the novel structure is composed of two cylindrical gearboxes, two connection cylindrical gearboxes, a hydraulic torque loader, a drive motor, two torque meter, a bearing block, a coupler, a shaft, a universal shaft and the like, wherein the two cylindrical gearboxes are completely the same and used for tests and include the tested gearbox and the accompanying tested gearbox, and the two connection cylindrical gearboxes are completely the same. The cylindrical gearbox mechanical closed test bench has advantages of other mechanical closed load test benches, can be suitable for any change of the center distance of the tested gearbox automatically, and has the advantages of being easy and convenient to use, safe and reliable.
Description
Art
The present invention's design is a kind of cylindrical gear punch-out equipment tool blocking test platform adapting to any centre distance.On railway locomotive and motor-car, it is right that gear case is directly passed to wheel after the moment of torsion that motor produces is increased, and works under hard conditions.In order to check gear case whether to reach design object, its reliability be verified, simultaneously also for design and development in future is accumulated experience, must test the new gear case of trial-production.This new structure successfully solves because gear case model is different or gear centre just need change different connection gear case problems apart from change, has features simple structure, safe and reliable feature.
Background technology
Railway locomotive and motor-car mostly adopt Cylinder Gear roller box, and be directly passed to wheel after the moment of torsion that motor produces is increased right, thus produce tractive force, gear case condition of work is severe.In order to check gear case whether to reach design object, to first verify its reliability, also accumulating experience for later design and development simultaneously, must test the new gear case of trial-production.Blocking test platform structure is simple, small investment, less energy consumption, is widely applied in gear and gearing experimental study thereof.Mechanical close formula except possessing enclosed feature, its load and rotating speed be two independently can controling parameters arbitrarily.Existing machinery blocking test platform is all test for the gear case of certain model, change gear case model or gear centre distance, because the gearbox pinion axle of railway locomotive or motor-car only has one end to stretch out, the other end is closed, this just needs to change different connection gear casees, both increase man-hour, cause waste again.Adopting the cylindrical gear punch-out equipment tool blocking test platform adapting to any centre distance, as long as gear is can adapting to of column type, fundamentally solving because gear case model is different or change gear centre apart from just needing to change different connection gear case problems.
Summary of the invention
In order to check gear case whether to reach design object, must first verify its reliability, also accumulating experience for later design and development simultaneously, will test trial-production new gear case out.Invention proposes providing a kind of features simple structure, safe and reliable new structure, it fundamentally solves because gear case model is different or gear centre just need change different connection gear case problems apart from change.
The present invention designs and solves the technical scheme that adopts of its technical matters is have in closed-loop: 1.2 identical Cylinder Gear roller boxs, and one of them is called tested gear case, and another is called accompanies examination gear case; 2.2 identical connecting cylinder gear casees; 3.1 hydraulic torque loaders; 4.2 torque gauges, all possess rotating speed and torque measurement function; 5.1 drive motor are positioned at outside closed-loop.Implementation method: because the gearbox pinion axle of railway locomotive or motor-car only has one end to stretch out, the other end is closed, in mechanical close ring, 2 identical, arrange in the same way for the Cylinder Gear roller box tested, one of them is called tested gear case, another is called accompanies examination gear case, connects 1 hydraulic torque loader, bearing seat, shaft coupling, axle and 1 torque gauge between the Large Gear Shaft During of both respectively, and this torque gauge and tested gear case Large Gear Shaft During are close to; 2 identical connecting cylinder gear casees are also arranged in the same way, its pinion shaft is connected by shaft coupling with the pinion shaft of test gear case respectively, tested gear case with to be connected between gearbox pinion axle except having shaft coupling, also have another 1 torque gauge, between two connection gear case Large Gear Shaft During, be connected with bearing seat, shaft coupling and universal shaft respectively; These two torque gauges of the large and small gear shaft terminal next-door neighbour of tested gear case all possess rotating speed and torque measurement function; Drive motor is positioned at outside closed-loop, is connected gear case Large Gear Shaft During is connected by shaft coupling with one; Cross slid platform can carry out angle test to shaft coupling.
The beneficial effect of the present invention's design is: 1, fundamentally solve because gear case model is different or gear centre just needs to change different connection gear case problems apart from change, thus has established solid theoretical foundation and operability for the test of the Cylinder Gear roller box of any centre distance; 2, easy to use: this features simple structure, safety, reliable; 3, both improve work efficiency, turn improve the repeat usage connecting gear case.
In motor model, travelling speed and wheel footpath three, any one is different, gear case model or ratio of gear are also different, cause gear case centre distance different, in order to test the gear case of different cylindrical gear centre distance, need different connection gear casees, both increased man-hour, and increased gear case spare unit again, the present invention designs and fundamentally solves because gear case model is different or gear centre just need change different connection gear case problem apart from change.
