Embodiment 1

[0068] An eddy current displacement sensor 10 is installed at the gear end of the axle box 1 of the wheel set driving device. Install the eddy current displacement sensor 10 on the ring hoop body 1-1 at the gear end of the shaft holding box 1, and the supporting surface of the sensor hollow hexagonal head 10-3 is pressed on the shaft holding box through the gap adjustment pad 11 and the anti-loosening pad 12, The driven gear 2 mounted on the axle by interference is used as the measured piece, the side surface of the web 2-1 is the measured surface, and the gap A between the measured surface and the end face of the sensor head is the physical quantity actually measured by the sensor.

[0069] Taking the displacement sensor for monitoring the transverse momentum of the axle-holding box at the gear end as an example, first determine that the allowable range of the transverse momentum of the axle-holding box is 0.05mm~0.5mm. When the traverse amount detected in real time is greate...

Embodiment 2

[0075] An eddy current displacement sensor 10 is installed at the non-tooth end of the axle box 1 of the wheel set driving device. Install the eddy current displacement sensor 10 on the ring hoop body 2 1-2 of the non-tooth end of the shaft holding box 1, and the front end of the eddy current displacement sensor 10 passes through the static seal 2 5, the transverse momentum adjustment seat 6 and the transverse momentum adjustment pad 7 The through hole 14, the supporting surface of the hollow hexagonal head 10-3 of the sensor is pressed on the axle holding box through the gap adjustment pad 11 and the anti-loosening pad 12, and the annular groove bottom surface 4- of the dynamic seal 4 installed on the axle is interference-pressed 1 as the measured surface.

[0076] As another embodiment, a displacement sensor for monitoring the transverse momentum of the axle box is provided at the non-tooth end. Firstly, the allowable range of the transverse momentum of the axle box is deter...

Embodiment 3

[0082] According to the first and second embodiments, the eddy current displacement sensor 10 is installed at the gear end and the non-tooth end of the axle box 1 of the wheel set driving device. The value at either end can be used as a check value for the value at the other end.

Abstract

The invention relates to the technical field of railway vehicles, in particular to a railway vehicle power wheel set axle-hung box transverse momentum monitoring method . The railway vehicle power wheel set axle-hung box transverse momentum monitoring method comprises the following steps: processing a mounting interface and an induction space for an eddy current displacement sensor on a gear end and a non-tooth end of an axle-hung box of a wheel set driving device, and assembling the processed wheel set driving device, comprising the following steps: installing an eddy current displacement sensor, an anti-loosening pad and a gap adjusting pad, completing the installation of an eddy current displacement sensor line, and carrying out the calculation of converting a measured gap value into the transverse momentum of the axle-hung box. According to the railway vehicle power wheel set axle-hung box transverse momentum monitoring method, problems caused by abnormal transverse momentum of the axle-hung box due to various reasons such as abrasion of parts of a driving device can be found in time; and the occurrence of abnormal grinding of parts, unbalance loading of the bearing, bearing faults and damage of related parts caused by abnormal grinding of the parts and unbalance loading of the bearing is reduced or even eliminated.

Description

technical field [0001] The invention relates to a method for monitoring lateral momentum, in particular to a method for monitoring lateral momentum of a railway vehicle power wheel set axle holding box. Background technique [0002] Railway vehicle power bogies usually use traction motors as the driving force. With the development of technology, the shaft-holding suspension of traction motors has been improved from the earlier use of sliding bearings to the shaft-holding suspension of rolling bearings. The specific suspension method is that the traction motor and the axle box are fastened together with bolts; each end of the axle box has a tapered roller bearing installed on the axle, which is used to realize the rotation of the axle relative to the axle box; The side of the traction motor away from the axle is hung on the bogie by flexible connection. In order to realize the reliable operation of the two tapered roller bearings, the two tapered roller bearings are arrange...
