Abstract

The utility model relates to the circulation and lubrication bearing device of the vertical pump of fluid machinery and comprises a bearing box, a bearing body, a bearing seat, a bearing gland, an adjusting screw cap, a cylinder, a ball bearing and a thrust bearing. The inner hole of the bearing body is the structure of a spiral groove and forms spiral clearance with the excircle of the cylinder; a oil storage house which is communicated with the upward slant hole is positioned above the spiral groove structure of the bearing body. The utility model can circulate the lubricant automatically and pour the lubricant substantially on the bearing so as to keep the system working under relatively lower temperature. The utility model improves the reliability of the mainframe and prolongs the maintenance circle.

Description

The chain-oiled bearing device

Technical field

The utility model relates to the bearing means of vertical pump in the fluid machinery.

Background technique

Lubricating of traditional vertical pump bearing parts, mainly be by bearing in rotatablely moving, rolling element spatters effect to fluid sharp, forms the oil droplet mist of oil circle of parabolic cone shape, wherein a part of oil droplet mist of oil has arrived the bottom of ball bearing, so ball bearing just obtains certain lubricated cooling action.If but rolling element is less to the sharp power of spattering of fluid, just then lubrication effect is little desirable.So traditional bearing means tends to because of lubricating not in place and making the temperature of bearing and lubricant oil too high, bearing life shortens.Cause the main frame time between failures short, the rate of fault height.

The model utility content

The technical problem that the utility model need solve is: at the problem lubricated not in place of traditional vertical pump bearing parts existence, and provide a kind of chain-oiled bearing device, can make the lubricant oil automatic cycle, and bearing is worked at a lower temperature.

The technological scheme that the utility model adopted: the utility model comprises bearing housing, bearing support, bearing support, bearing gland, adjust nut, oil tube, ball bearing, parts such as thrust-bearing, the endoporus of bearing support are helical groove structure, and form gap between screw with the cylindrical of oil tube; The helical groove structure top of bearing support endoporus has shoe cream room, and oil pocket is connected upwards inclined hole.

The beneficial effects of the utility model: because the endoporus of the utility model bearing support is a helical groove structure, formed one gap between screw between it and the oil tube, thereby generation pump-absorb action, a large amount of lubricant oil are pumped to shoe cream room from oil sump, throw away by the inclined hole that makes progress again, water and drench on ball bearing, ball bearing is lubricated, then lubricant oil falls back in the oil sump again.So circulation can make bearing remain at the good lubrication state repeatedly.

Fig. 2 is the helical groove structure schematic representation of the utility model bearing support endoporus.

Embodiment

Referring to Fig. 1, Fig. 2, the utility model comprises bearing housing 1, bearing support 2, bearing support 3, bearing gland 4 is adjusted nut 5, oil tube 6, ball bearing 7, thrust-bearing 8 parts such as grade, wherein the effect of bearing housing 1 is to provide a mounting base and benchmark to all the other all parts, and forms a good oil sump of connectedness, increase heat diffusion area again, and played stable pasta.Bearing support 3 provides reference for installation and bears the radial force that main shaft 10 transmits by bearing support 2 for ball bearing 7.Bearing gland 4 makes ball bearing 7 axially locating and whole system is communicated with atmosphere.Adjust nut 5 except that directly the axial force of main shaft 10 being passed to the thrust-bearing 8 by bearing support 2, it is the height of can regulate main shaft 10 also.The effect of bearing support 2 is by flat key 11 axial force of main shaft 10 and radial force to be passed to ball bearing 7 and thrust-bearing 8.The endoporus of bearing support 2 is helical groove structure (shown in the label among Fig. 2 12), form a suitable gap between screw between it and the oil tube 6, the bottom of this gap is about to be flooded more than 1/3 in oil sump 22, because the effect of flat key 11, bearing support 2 rotates synchronously with main shaft 10, at this moment, suitable gap between screw just can produce pump-absorb action, lubricant oil is risen to the shoe cream room 20 from oil sump 22, throw away by the inclined hole 21 that makes progress rapidly owing to action of centrifugal force then, water and drench above ball bearing 7, thus comprehensive lubricating bearings and take away its part heat, and the lubricant oil of working drops in the oil sump 23.Big section channel connection is arranged between oil sump 22 and the oil sump 23, thereby realize the automatic cycle of lubricant oil.All there are a plurality of inner web pieces 13 and outer muscle sheet 14 in the interior outside of the oil pocket 23 of bearing housing 1, and they have bigger area and remove to absorb and distribute heat in the fluid.Simultaneously its outer muscle sheet 14 be air-cooled be again the radiating fin of water-cooled, just form water cavity 24 in case load onto water jacket 9, the access turnover water pipe just can be realized water-cooled.Therefore, water jacket 9 can be loaded onto at any time or pull down according to the temperature of working medium.The utility model assembles according to following order:

A, thrust-bearing 8 inner rings are contained in bearing support 2 bottoms, then ball bearing 7 are loaded on its middle part;

B, be loaded on the outer ring of thrust-bearing 8 in the bearing housing 1 after, promptly the part that above-mentioned a step is installed swings in wherein stably; If high temperature media should be adorned water jacket 9 this moment;

C, be pressed into bearing support 3 on top, the bearing gland 4 of then packing into;

D, up install oil tube 6 from the bottom, this moment, assembling finished at last, and can integral body be loaded on the pedestal;

When e, general assembly, main shaft 10 is worn from the mesopore of oil tube 6 from the bottom up, and works good with the hole and the flat key 11 of bearing support 2, with adjusting the relative position that nut 5 mixes up main shaft 10.
