Abstract
The utility model relates to a dual-rotary drum device for a tyre tester, which is characterized in that the tested tyre and a pair of rotary drums are pressed; the pair of rotary drums are connected mechanically and have different peripheral speed. The surface of the dual-rotary drum device for a tyre tester is provided with a particular groove-shaped flower pattern type metallic product. The dual-rotary drum device for a tyre tester can exert radial load and circumferential load (circumferential direction load) on the tested tyre. The test of the service life of finished goods of tyres (such as a rupture of tyre, etc.) with low speed and big torque needs to be implemented under the operating conditions, but the test device which can simulate the operating conditions is still not provided. The utility model can solve the technological problem. The weak link of the tyre can be discovered earlier by using the dual-rotary drum device for a tyre tester to implement the service life of finished goods of tyres, which can shorten the development period of the product and can save human power and material resources.
Description
Double rotating drum device described in the utility model is a kind of novel test device that is used for tire (especially low speed large torque tire such as agricultural tyre) finished product life test machine.
At present, the existing special-purpose single drum tester of the tire of the little moments of torsion of high speed such as tyres for passenger cars, truck tyre is carried out the finished product durability test.This testing equipment mainly applies radial load to tested tire.But, do not develop the manufacture test machine that is applicable to low speed, high pulling torque tire (as agricultural tyre, off-the-road tyre etc.) at present both at home and abroad as yet.Different with the testing requirements of tire such as automobile, the low-speed big tire applies the radial load to tested tire except requiring test unit when testing, and also requires to apply circumferential load (circumferentially load) to it.
Tested tire is applied the existing many technical schemes that can be known of radial load.The purpose of the utility model then applies this technical barrier of circumferential load for solving.The double rotating drum that mechanically links compresses mutually with tested tire, has not only applied radial load to it, have simultaneously tested tire is produced trackslip, the function of slippage, thereby also applied circumferential load.
Fig. 1 is a front view;
Fig. 2 is attached view;
The example of Figure 1 and Figure 2, can explain its principle of work: two rotary drums (generally making) 1 and 2 by metal material, a fixed fifth wheel 3 and 4 respectively on it, connector strip 5 make fifth wheel 3 and 4 rotation that fricton-tightly connects together (also can use other mechanical drive form to reach this purpose.This moment, connector strip 5 can be a mechanical transmission mechanism, as transmission case).Tested tire 6 is pressed under certain radial load and drives 1 and 2 rotations (also can be that rotary drum 1 or rotary drum 2 drive tested tire 6 rotations) above the double rotating drum.Obviously, because the linear velocity of each point equates on the connecting band 5, when fifth wheel 3 and 4 diameters were unequal, its angular velocity must be unequal.Example as shown in Figure 1 and Figure 2, the diameter of wheel 4 is littler than the diameter of wheel 3, so its angular velocity is bigger than the angular velocity of wheel 3.So when two rotary drums 1 and 2 equal diameters, its peripheral speed is just unequal.Shown in Figure 2 as Fig. 1, the peripheral speed of rotary drum 2 is bigger than the peripheral speed of rotary drum 1, and the peripheral speed of tested tire 6 must fall between.Because only in this way, for tested tire 6, at contact region A, sliding speed and friction force identical with its peripheral speed and that pair of opposite is relative could appear in B two places, thereby cause the mechanical balance of double rotating drum mechanism.This just relative slip at contact region A, B place causes that friction force has applied circumferential load to tested tire.Except that selecting rightly the relative sliding velocity, for increasing the friction force of rotary drum and rubber, also special design should be done in the metal surface of rotary drum, as make flute profile decorative pattern etc., its edge should be sharp keen, and groove width should be between 1 to 4mm.
Rotary drum 1 in the example and 2 equal diameters, but also can be designed as unequal.In a word, the diameter ratio of establishing rotary drum 1 and 2 is i
1, fifth wheel 3 and 4 ratio are i
2, then calculate i according to the experience of metal rotary drum
1With i
2Ratio should be a certain value between the 1:1.01-1:1.7.Because the gear train between the fifth wheel 3 and 4 is nonslipping, this value also is the ratio of two rotary drum peripheral speeds.
Double rotating drum 1 and 2 is fixed on the framework 7 symmetrically, and the center line 8 of this framework 7 can be around axle 9 rotations.This structure has guaranteed after the center line 8 of the axle center of tested tire 6 10 preliminary aligning frameworks 7 axle center 10 is stably remained on the center line 8, thereby radial load G is born by two rotary drums equably.
Claims (3)
1, a kind of double rotating drum device that is used for tire manufacture test machine, it is characterized in that: tested tire compresses mutually with the double rotating drum device, two rotary drums 1 and 2 are installed in can be on the framework 7 that axle 9 rotates, and the ratio of its peripheral speed is 1: 1.02-1: a certain fixed value between 1.5.
2, according to the double rotating drum device of claim 1, it is characterized in that double rotating drum has the metal surface of band-slot decorative pattern, groove width is 1-4mm, its edge should be sharp edge.
3, according to the double rotating drum device of claim 1, it is characterized in that: fifth wheel 3 and 4 is fixed in respectively on rotary drum 1 and 2, and by the connecting band 5 that does not the produce slip with it rotation that links together.
