740mm forging resilient wheels for Mexico metro safety wheel precision machining introduction

Production  specification of resilient wheels precision injection hole ready for assemble locomotive rolled wheel

An elastic wheel for rail vehicles, comprising a rim, a wheel center, and a damping element located between the rim and the wheel center, wherein the wheel center is provided with an axial direction for accommodating and installing a wheel-mounted brake disc. An annular groove concave relative to the side of the tire. The invention can realize the reasonable installation of the wheel-mounted brake disc on the elastic wheel, and the elastic wheel can withstand the thermal load generated by the wheel-mounted brake disc, has excellent vibration and noise reduction performance, long service life and good bearing performance .

Manufacture process of 740mm forging resilient wheels for Mexico metro safety wheel precision machining

The adopted method for rolling fatigue testing of elastic wheels belongs to the technical field of testing and testing of components of rail transit vehicles. The method includes the basic steps of determining the load type, drawing up the load cycle test spectrum, establishing the load cycle loading device, collecting the load test data, and obtaining the judgment conclusion of the fatigue test, so that the actual running state of the elastic wheel can be simulated with the help of the load cycle loading device. Therefore, through the test, the scientific basis for design, improvement and other research work can be obtained, and it can be used to determine whether the rolling fatigue strength of each key component in the elastic wheel, especially the elastic damping element, is qualified, so that the application of the test device can be extended to Test Equipment.
This elastic wheel fatigue test method includes the following steps: performing a static load test on the elastic wheel to obtain its static load stiffness Ka; after the dynamic fatigue test of the elastic wheel is completed, the elastic wheel is placed at room temperature for 24 hours. Then, repeat the static load test to obtain the static load stiffness Kb; obtain the stiffness change ΔKab between the static load stiffness Kb and the static load stiffness Ka, calculate the stiffness fatigue change rate θab, and compare the stiffness fatigue change rate θab with the technical requirement change rate Compare and judge whether the fatigue performance of elastic wheel is qualified. The test method can accurately quantitatively compare and analyze the test results. Compared with the traditional visual inspection of the appearance changes after the fatigue test, the quantitative comparative analysis is more accurate in determining the results. And can provide data support for the research and development of the anti-fatigue performance of elastic wheels

Strength of 740mm forging resilient wheels for Mexico metro safety wheel precision machining

This elastic wheel is an elastic wheel equipped with a wheel disc 1 and a rim 3 supporting a tire 20 . Such an elastic wheel has a pair of guides 4 fixed annularly on the inner peripheral surface of the rim 3 , and a base fixed annularly disposed on the roulette 1 or the outer peripheral surface of the rim 1 . A pair of wall portions 5 on the outer peripheral surface of the wheel rim 2 in the regions of both sides in the wheel axial direction are respectively provided with elastic bodies 6 annularly between the side surface of the guide 4 and the side surface of the wall portion 5. On the rubber elastic body 6, at least one belt 8 is arranged in an annular shape. Using shear deformation of the provided rubber elastic body 6 to absorb vibration, especially at small input, can improve ride comfort, anti-vibration performance, and anti-noise performance, and also improve operational stability. In addition, regarding the anti-noise performance, the anti-noise effect in the high frequency region of 100 Hz or more is excellent.
