Abstract
The utility model relates to a wheel axle fatigue tester, which is capable of comprehensively establishing a journal rotating bending and axial loading test mode by aiming at a solution to implementing fatigue tests and axial loading on journals, so that comprehensiveness of the fatigue tests on wheel axle integrality is improved. The wheel axle fatigue tester comprises a loading beam and a platform, a wheel is radially fixed onto the platform, the end of a to-be-tested wheel axle is axially fixed onto the platform, a vertical actuating cylinder, a transverse actuating cylinder and a longitudinal actuating cylinder are respectively connected to a journal of the to-be-tested wheel axle, the journal of the to-be-tested wheel axle is mounted inside a mounting seat by means of a rolling bearing, and the vertical actuating cylinder, the transverse actuating cylinder and the longitudinal actuating cylinder are respectively connected to the mounting seat. The fatigue tests of the journal, an axle body and a radial plate of the wheel axle can be comprehensively realized based on the tester and a method.
Description
Technical field
The utility model relates to the device that a kind of axle journal that is directed against rail vehicle wheel shaft is implemented torture test, belongs to the track traffic technical field.
Background technology
Along with the domestic city track traffic popularize rapidly the significantly lifting with Vehicle Speed, for the bogie frame of bearing body and transmitting tractive power higher design and use requirement has been proposed.Wherein, wheel shaft is bogie important composition parts, to wheel shaft carry out torture test be guarantee long-term, at a high speed and the guarantee of safe operation.
At present domestic test unit to wheel shaft mainly is divided into eccentricity excitation formula, rotoflector formula, whole tumbling-type and free beam rotoflector formula structure, and correspondingly test method is confined to the torture test at axle body, disc position.
The test unit that above-mentioned prior art generally adopts still can not carry out the torture test at axle journal position, and its means to save the situation can only be through the test figure to other position, converts accordingly to simulate the fatigue strength coefficient of axle journal approx.
And, based on the test unit of said structure and test method, only be to apply radial loaded and loading and Data Detection export function on not having axially to wheel shaft.
Therefore, use existing wheel shaft fatigue experimental device still can't from system set up load with stress crooked or and the axle journal endurance ratio between corresponding relation, still can not estimate the rationality that whether possesses of wheel shaft structure design and material all sidedly.
In view of this, the special present patent application that proposes.
The utility model content
The described wheel shaft fatigue experimental device of the utility model; Its purpose is to solve the problem of above-mentioned prior art existence and can implements torture test and axial loading solution to axle journal; Thereby set up axle journal rotoflector and the test method that axially loads all sidedly, comprehensive in the hope of improving the whole torture test of wheel shaft.
For realizing above-mentioned purpose of design, described wheel shaft fatigue experimental device mainly includes:
Load crossbeam and platform, fixing vehicle wheel, axially fixing radially on platform by the end of examination wheel shaft;
By the axle journal place of examination wheel shaft, connect vertical cylinder, horizontal cylinder and vertical cylinder respectively.
Apply effect and simulate that the interior ring of axle journal press-fits environment under the actual user mode for improving axle journal place combined load further, the improvement project that can take is that the axle journal that is tried wheel shaft is installed on the inside of mount pad through rolling bearing; Vertical cylinder, horizontal cylinder and vertical cylinder are connected to mount pad.
Content to sum up; What the utility model wheel shaft fatigue experimental device had advantage is; Can realize the torture test of axle journal, axle body and the disc of wheel shaft all sidedly based on the test battery apparatus and method; Setting up with the axle journal with axial loading scheme simultaneously is the wheel shaft rotating bending test data of representative, for improving the design of wheel shaft structure and optimization of material the data support is provided.

Embodiment
Embodiment 1, and is as depicted in figs. 1 and 2, is used to realize taking turns the test unit of shaft neck fatigue test method, mainly includes to load crossbeam 7 and platform 3.Wherein,
Fixing vehicle wheel 8, axially fixing radially on platform 3 by the end of examination wheel shaft 4;
By the axle journal place of examination wheel shaft 4, be installed on the inside of mount pad 5 through rolling bearing 10, vertical cylinder 6, laterally cylinder 1 and vertically cylinder 9 be connected to mount pad 5.
The described shaft neck fatigue test method of taking turns is to be pasted with the stress detection lug in wheel shaft 4 corners of being tried of contiguous wheel 8;
In implementing axle journal torture test process, try wheel shaft 4 to do circumferential rotation at the uniform velocity, above-mentioned vertical cylinder 6, laterally cylinder 1 and vertically cylinder 9 operate to accomplish the required cycle of torture test respectively to by the axle journal imposed load of examination wheel shaft 4.
Before implementing the axle journal torture test, carrying out the wheel shaft radial stress demarcates; Promptly in horizontal cylinder 1 when axle journal applies horizontal push-and-pull load times without number; Vertical cylinder 6 is in free state with vertical cylinder 9, obtains the stress detection lug data output of being pasted by examination wheel shaft 4 corners;
In vertical cylinder 9 when axle journal applies vertical push-and-pull load times without number; Vertical cylinder 6 is in free state with horizontal cylinder 1; Obtain the stress detection lug data output of being pasted, thereby obtain the stress corresponding relation of rotation bent angle between radially push-and-pull load and the quilt examination wheel shaft 4 by examination wheel shaft 4 corners.
Before implementing the axle journal torture test, carrying out axle axial stress demarcates; Promptly in vertical cylinder 6 when axle journal applies axial push-and-pull load times without number; Vertically cylinder 9 is in free state with horizontal cylinder 1; Obtain the stress detection lug data output of being pasted, thereby obtain the stress corresponding relation of rotation bent angle between axial push-and-pull load and the quilt examination wheel shaft 4 by examination wheel shaft 4 corners.
In implementing radially torture test process of axle journal, laterally cylinder 1, vertical cylinder 9 apply radially push-and-pull load to accomplish the torture test of regulation cycle times without number to axle journal.
Implementing journal shaft in the torture test process, vertical cylinder 6 applies axial push-and-pull load times without number to axle journal, promptly in the axial fatigue test, implements radially torture test of axle journal.
