Embodiment 1

[0026] Such as Figure 1-Figure 5 as shown,

[0027] An integrated waterproof and dustproof test machine for subway axle box bearings, including a body 1, a main shaft 2, a waterproof test box 3 and a dustproof test box 4, the main shaft 2 is installed on the body 1 through a bearing seat 5, and the main shaft 2 is connected to a power transmission device And can rotate around bearing seat 5 under the drive of power transmission device, the quantity of bearing seat 5 is two, is provided with angular contact ball bearing in bearing seat 5, is provided with bearing gland 6 on bearing seat 5. The bearing seat 5 is processed from a high-quality steel, and is used to install the supporting bearing of the main shaft 2 - an angular contact ball bearing. The bearings are used in pairs, installed back to back, and bear a large axial force. The bearing seat is used in conjunction with the main shaft and the bearing gland to realize the axial positioning of the angular contact ball bear...

Abstract

A subway axle box bearing waterproof and dustproof integrated testing machine provided by the present invention comprises a machine body, a main shaft, a waterproof test box and a dustproof test box, the main shaft is installed on the machine body through a bearing pedestal, two ends of the main shaft are respectively provided with a positioning device used for installing an axle box body, and the axle box body can be fixed on the machine body through the positioning devices. An axle box bearing is arranged in an inner hole of the axle box body; the end part of the main shaft can be mounted in an inner hole of the axle box bearing; the waterproof test box and the dustproof test box are located at the two ends of the spindle respectively, and the spindle box body is located in the waterproof test box or the dustproof test box. A water circulation device or an air circulation device in the waterproof test box or the dustproof test box truly simulates raining weather and sand storm weather, stable water flow, uniform spraying, stable air pressure, sand and dust raising, inlet and outlet circulation and good waterproof and dustproof effects are guaranteed, the test requirements are met to the maximum extent, the universality is high, and the test efficiency is high. The industrial blank of waterproof and dustproof test equipment for the type of subway axle box bearing is filled.

Description

technical field [0001] The invention relates to the technical field of mechanical testing, in particular to a waterproof and dustproof integrated testing machine for subway axle box bearings. Background technique [0002] Axle box bearings used in subway lines need to do waterproof and dustproof tests. The integrated waterproof and dustproof test of subway axle box bearings is also called sealing test. It is used to test the sealing performance of bearings or axle boxes. It can be divided into static Sealing test and dynamic sealing test. The static sealing test is used to detect the sealing performance of the axle box body; the dynamic sealing test is used to detect the sealing performance of the subway axle box bearing. At present, there is no such waterproof and dustproof test equipment specially for subway axle box bearings in the market. Contents of the invention [0003] The object of the present invention is to provide an integrated waterproof and dustproof testin...
