Description

A kind of high-speed overload bearing seal performance test table apparatus
Technical field
The utility model relates to the testing apparatus of bearing seal performance, particularly relates to a kind of high-speed overload bearing seal performance test table apparatus.
Background technology
Railway bearing is realizing that the railway locomotive speed per hour can be described as the high-speed railway bearing when running to 200km/h; In recent years; Effort through domestic bearing industry; Design and manufacture view at the high-speed railway bearing makes important progress, developed 350 kilometers EMUs wheels of speed per hour to the axle box bearing sample.Yet, owing to do not have speed per hour more than 300 kilometers high-speed railway bearing correlation test platform lack test figure accumulation, enough bearing performance data can not be provided, can't satisfy high-speed railway bearing application requirements.Modern bearing seal performance test apparatus generally adopts two kinds of physical constructions, i.e. bridge architecture and cantilever design.The advantage of cantilever design is that each test process is simple to operate; Need not the dismounting main shaft during assembling test bearing; Directly change measured bearing and get final product, be only applicable to the test occasion that load is less or rotating speed is lower but this structure is subject to the restriction of cantilever design and spring bearing.A kind of in addition bridge architecture main shaft is a two end supports; Measured bearing places the main shaft centre position; The load-bearing capacity of its main shaft is greater than the load-bearing capacity of the main shaft of cantilever design, and owing to be two end supports, so can load the power of cantilever design twice under the situation of identical spring bearing; But this structure need be dismantled main shaft when changing measured bearing at every turn fully, and just can carry out the replacing of measured bearing after need spring bearing being pulled down.Though bridge architecture has promoted the size of the loading force of bearing test; When but the requirement of experiment of working as the bearing of being tested applies king-sized load and requires extra high rotating speed simultaneously; This kind structure is same because the restriction of spring bearing also can't or be difficult to satisfy requirement of experiment.
Summary of the invention
Solve the sealing property test problem of large high-speed heavy-duty bearing pointedly, the purpose of the utility model provides a kind of high-speed overload bearing seal performance test stand device experiment table apparatus that carries out performance test under the situation of simulation bearing real work.
The technical scheme that the utility model adopts is:
The utility model is coaxial installation main shaft in the dissection type high-low temperature test chamber; Stretching out the outer main shaft two ends of dissection type high-low temperature test chamber is bearing in the bearing seat separately through spring bearing respectively; The main shaft external part that is positioned at a bearing seat is connected with the output shaft of motor through shaft coupling, and dissection type high-low temperature test chamber, two bearing seats and electric machine support are installed on the same base; The axle journal that is positioned at the main shaft axle collar both sides of dissection type high-low temperature test chamber is respectively identical, a big outer little cone; Two tested high-speed overload bearings are installed in respectively on the cone of both sides, fix with axle sleeve set nut separately after the bearing axle sleeve is installed respectively on two cones; Two tested high-speed overload bearing outer rings are installed respectively and are loaded cover; Two axial loading cylinder piston rods that symmetria bilateralis is installed symmetry respectively withstand on each bootstrap loading cover lateral surface; Two radial loaded cylinder piston rods reverse vertical respectively withstand on each bootstrap loading cover face of cylinder; More than each loads cylinder cylinder part and is installed in outside the sweat box, only will load cylinder piston rod and stretch in the dissection type high-low temperature test chamber; At dissection type thermocycling upper box part water, wind shower nozzle are installed, temperature sensor and capillary pipeline are set in the dissection type high-low temperature test chamber, capillary pipeline is connected with outside heating-cooling equipment.
The beneficial effect that the utlity model has is:
The technological difficulties of high-speed overload bearing test-bed mainly contain two aspects; Be the strength problem and the support problem of main shaft; Because testing table turns round under the high-speed overload operating mode; The guarantee of the security of its main shaft has great importance, and on the other hand, general plain bearing also can't satisfy such working condition requirement at all.This bearing test-bed invention agent structure has been given up employed bridge architecture of general bearing test-bed main shaft and cantilever design, and has been to use a kind of load to offset, the new structure of couple type.The superiority of its structure is:
Loading force was in the opposite direction when (1) two measured bearing loaded, and on same plane, then two measured bearings lean on closely more, and the couple that radial load produces on main shaft will be more little, and the suffered moment of flexure of axle will be more little, helps improving the fatigue strength of main shaft more.
(2) moment of flexure and the constraining force balance of spring bearing that produce of radial load, theoretically, the strong point is far away more apart from load(ing) point, and the suffered load of spring bearing is just more little.Reach certain distance, even very big of loaded load, therefore the load that spring bearing receives also seldom also can adopt common bearing as spring bearing.
The utility model can be to internal diameter greater than 130mm, and rotating speed requires 2000r/min above (corresponding train speed per hour 330km/h), and single cover bearing loaded load requires the above sealing bearing of 200kN to test.
