Description
Technical Field
The invention relates to the technical field of rack trains, in particular to a detection device for a guide rail type tooth entering mechanism.
Background
The rack rail guiding device is a key device on a rack rail line and is used for transiting a wheel rail driving section and a rack rail driving section, and the main function of the rack rail guiding device is to ensure the synchronization of the rotation speed of gears before the gears are meshed with racks, so that the situations of being unfavorable for driving safety such as top teeth and impact are avoided. The quality of the performance of the rack rail guiding device directly influences the running stability and safety of the rack rail train, and scientific and reasonable structural parameter design plays a better tooth-entering effect on the rack rail guiding device, reduces tooth-entering impact and has important significance in ensuring driving safety.
The fatigue durability of the rack rail lead-in device is an important index for evaluating its performance. The fatigue durability research of the rack rail lead-in device can accurately estimate the fatigue life of the mechanical structural components, ensure that the components cannot be subjected to fatigue failure in the service period, and further improve the stability and safety of the operation of the rack rail.
The invention discloses a fatigue test device for a mountain train introduction device, which is characterized in that a basic experiment table is used as a base, and components such as a driving guide rail, a clamping device, a tested introduction device and the like are fixed on the basic experiment table, and the clamping device can be used for installing and fixing various types of tested introduction devices so as to meet different test requirements. The horizontal guide rail control gear is meshed or separated from the horizontal guide rail control gear, and meanwhile, the vertical guide rail control gear on the horizontal guide rail control gear reciprocates on the tested leading-in device and is meshed and driven repeatedly. In addition, the vertical guide rail control gear can move up and down, so that the purpose of adjusting the center distance is achieved, and the detection requirements of the guiding devices with different specifications are met. The fatigue testing machine for the lead-in device drives the gear to rotate through the gear driving device, and simultaneously controls the gear to do linear reciprocating motion on the test rack through the vertical guide rail, so that the meshing state of the gear and the rack in the mountain rack rail train is relatively perfectly simulated, and the fatigue testing machine for the lead-in device is provided for detecting fatigue wear, testing fatigue life, detecting working condition movement temperature and the like. However, there remain disadvantages, as follows:
under the actual use condition, due to the existence of friction resistance, the gear is meshed with the introduction device to generate vibration, and the existence of vibration can aggravate impact load when the gear is meshed with the introduction device, so that the fatigue life of the introduction device is affected. Therefore, reducing vibration caused by frictional resistance under actual working conditions is one of the important means for improving the service life of the introduction device.
In the prior art, a common method for reducing vibration caused by friction resistance is to coat grease on the meshing surface of a gear and an introduction device. The principle is that the lubricating grease can reduce the whole friction resistance of the meshing surface of the gear and the leading-in device, so that vibration can be effectively restrained when the gear is meshed with the leading-in device, impact load when the gear is meshed with the leading-in device is weakened, and the fatigue life of the leading-in device is prolonged. In addition, the amount of the lubricating grease can be adjusted to a certain extent in actual operation aiming at different parts of the meshing surface of the gear and the guiding device, so that the friction resistance difference value of different parts of the meshing surface of the gear and the guiding device can be reduced, the stress of a meshing system of the gear and the guiding device is more balanced, the vibration when the gear is meshed with the guiding device is further restrained, and the fatigue life of the guiding device is prolonged.
However, in view of the above-mentioned working conditions, in the conventional test device, it is difficult to adjust the amount of grease for the difference in frictional resistance between the gear and the different parts of the engagement surface of the introduction device in actual use, resulting in possible inaccuracy in the measured fatigue life of the introduction device.
Therefore, there is a need for a guide rail type gear-in mechanism detection device, which can adjust the amount of grease according to the friction resistance difference between different parts of the meshing surfaces of the gear and the guiding device, so as to ensure the accuracy of the experimental result.

Further, in this embodiment, after the gear 9 has travelled the stroke, the third sliding mechanism 14 controls the gear 9 to move upwards, so that the gear 9 is separated from the introduction device, and then the second sliding mechanism 4 drives the gear 9 to move backwards for resetting, performing reciprocating motion, observing the wear of the tooth entering mechanism and measuring the fatigue life of the tooth entering mechanism.

In the present invention, the number of the engagement surfaces of the gear 9 is plural, and in this embodiment, each tooth of the gear 9 is set as an independent engagement surface. In this embodiment, the improvement of the uniformity of distribution of the grease is merely referred to as improvement of the uniformity of distribution of the grease on the single teeth of the gear 9.

As shown in fig. 1 to 5, in the detection device for a guide rail type tooth entering mechanism according to the present invention, on the basis of the above-mentioned mode, a universal joint is further disposed between the drop nozzle 18 and the supporting frame 19, and the universal joint is used for adjusting an angle of the drop nozzle 18 towards the first tooth profile curved surface 22.
In this embodiment, the angle of the drip nozzle 18 facing the first tooth profile curved surface 22 can be further adjusted by the universal joint, so that the accuracy of the grease dripping on the first tooth profile curved surface 22 can be further improved. On the other hand, the angle of the drip nozzle 18 facing the first tooth profile curved surface 22 is adjusted by the universal joint, so that the application scene of the invention can be enriched, and the practicability of the invention is improved.
As a preferred embodiment, further, a limiting mechanism is disposed between the first slider 6 and the first rail 5, and a limiting mechanism is also disposed between the third slider 16 and the third rail 15, where the limiting mechanism is used for locking the sliding of the first slider 6 and the third slider 16. By adopting the structure, the first sliding block 6 and the third sliding block 16 are prevented from sliding due to unexpected situations in the test process, and the reliability of the invention in actual use is improved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
