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
