Description

Hot-fluid vapour-pressure type bearing defatting machine

Technical field

Hot-fluid vapour-pressure type bearing defatting machine described in the utility model is to apply to railway get off in the bearing maintenance, remove by maintenance bearing inside the equipment of residual waste lubricating oil fat.

Background technology

At present, in the service work of rolling stock, each car inspection and repair department is for the removing work of the bearing internal grease of getting off of being overhauled, owing to do not have degreasing equipment so generally take method degreases such as water under high pressure, high temperature oil cooking method or washing agent cleaning.The energy that the consumption of said method ubiquity is a large amount of and material also cause the pollution of environment, contract I year over become the insoluble problem of car inspection and repair department always.At existing problem in the above-mentioned prior art, design a kind of novel hot-fluid vapour-pressure type bearing defatting machine, thereby existing be very necessary in problem.

Summary of the invention

In view of existing problem in the above-mentioned prior art, the purpose of this utility model be a kind of novel structure of design, advanced in performance, power consumption is little, efficient is high, energy is big, cost is low, degreasing is clean, pollution face is little, do not need the new type passenger car bearing of characteristics such as additional treatments equipment and the degreasing plant of other all kinds of bearings.So being a kind of being suitable for, the utility model in maintenance such as passenger vehicle vehicle, locomotive, lorry, is used to remove the novel hot-fluid vapour-pressure type bearing defatting machine of bearing internal grease.

Hot-fluid vapour-pressure type bearing defatting machine described in the utility model; Its structure is by heater, the bearing inner ring lifting mechanism, and the sealed bearing device, gas impact machine structure is formed; Heater is loaded on the feed end of body, and the sealed bearing device is loaded on the body discharge end, and the sealed bearing device links to each other with gas impact machine structure; The bearing inner ring lifting mechanism is loaded in the sealed bearing device body; The sealed bearing device is combined by fixing upper cover and removable low head, and is installed in the top and bottom of sealed bearing appliance stand respectively; Heater is made up of one group of three heat induced coil; Be respectively bearing and give thermoinduction coil, bearing heat induced coil and bearing insulation induction coil; Three kinds of induction coils are installed on the heating arrangements support of body, and can realize upper and lowerly moving both vertically synchronously.Bearing inner ring lifting mechanism described in the utility model is by lifting cylinder and supporting pallet and formed; Support pallet and be loaded on the piston rod top of lifting cylinder.The upper cover of sealed bearing device described in the utility model is a drum-shaped structure, low head is the truncated cone-shaped structure, has open-work in the middle of the round platform, the lower end of upper cover and the upper end of low head all have the sealing seam, in the sealing seam rubber seal ring is housed, the middle open-work of low head links to each other with the connect fat box of grease-conveying tube with underpart by leading the fat groove.Low head described in the utility model is combined by low head outer ring body and support pallet, supports the middle concentric structure that forms that pallet is positioned at outer ring body, and outline body is a truncated cone-shaped.

In the maintenance of railway passenger train, each maintenance department must dispose a large amount of lubricant greases in the bearing before the vehicle wheel set bearing is overhauled.And methods such as high temperature poach, the oil of currently used removing lubricating grease boil, activated detergent cleaning all will cause the change of lubricant grease generation physics or chemical property, then increase the expense of harmless processing before the discharging, increase simultaneously and handle the place of polluting.The utility model is different from the existing processes flow process fully, and bearing heating, grease soften, bearing inner ring lifts integrally closed and utilize, thus the technological process that utilizes the pressure air circulation that grease is blown down.The utility model fully takes into account the structural shape of passenger vehicle bearing and designs has following outstanding design feature:

1, because only adopting simple disposable high temperature heating can not reach whole grease desaturations, the inner contained waste and old grease of maintenance bearing forms grease stream, and potential variation harm is arranged because unexpected high temperature heated mandrel is honoured the bearing material, so the utility model adopts three step heatings promptly to adopt and gives heat, heating, insulation, make like this in the bearing body waste and old grease fully thinning being easy to flow, and the plastic-steel retainer that does not damage bearing makes its temperature between 70-80 ℃.

2, the utility model structure is primarily aimed at the passenger vehicle bearing, because the inner and outer rings of passenger vehicle bearing has rib, and be clipped in the slit that grease between retainer and inner and outer rings does not have outflow, so must make inner and outer rings throw off certain distance mutually can go out internal grease usefulness gas, ring lifting mechanism in the utility model adopts, interior ring is lifted, make between inner and outer rings to produce the slit and flow out in order to grease.

3, the utility model hermetically sealed when guaranteeing gas towards bearing grease, so increased the sealed bearing device, and the low head of employing activity promotes to move on the bearing lower end, the bearing upper end is closely contacted with upper cover, form a combined sealed body, thereby with interior ring lifting mechanism and bearing seal in it.

4, the upper cover in the sealing device of the present utility model is loaded on the upper bracket, and with the appendix of gas impact machine structure be connected with guarantee upper and lower end socket close close into a sealing device after, the compressed air of gas impact machine structure flings the internal void of bearing through appendix through upper cover, and wherein waste and old grease is discharged in the collection fat case through the grease-conveying tube of leading the fat groove of low head bottom.

5, upper and lower end socket of the present utility model improves the degreasing requirement that can adapt to freight car bearing and locomotive bearing a little.

6, the utility model adopts special material to manufacture bearing drive transfer mechanism, thus bearing after heat treated, be not magnetized, so the utility model can not adorned the bearing demagnetization machine structure in housing construction.But also can install as requested do standby.

In sum, the utlity model has advanced technological process; Adopt the utility model directly to reclaim,,, also will bring huge economic benefit and social benefit simultaneously for car inspection and repair department maintenance bearing provides convenience so reduced pollution and producing cost to bearing grease.
