Abstract

The utility model discloses a bearing box sealing device which comprises an end cap, a sealing gland and bolt fasteners arranged between the end cap and the sealing gland. The bearing box sealing device is characterized by further comprising a rotary bushing, a double-lip frame seal and a vent plug screw; the double-lip frame seal is mounted between the sealing gland and the rotary bushing, the vent plug screw is mounted on a vent in the upper portion of the end cap, an oil return hole is formed in the end cap, the sealing gland is provided with an oil return cavity, and a through hole is formed below the oil return cavity; a protruded oil slinger is arranged on the rotary bushing and oil slinger teeth are formed in the middle of the rotary bushing. The bearing box sealing device is simple in structure and convenient to machine, oil leakage easy to be caused in running of the bearing box is avoided, utilization rate of lubricating oil is increased effectively, and lubricating effect is improved.

Description

The Seal in Bearing Box device

Technical field:

The utility model relates to a kind of seal arrangement of axial-flow blower bearing housing technical field.

Background technique:

In fields such as metallurgy, electric power, environmental protection, moving (quiet) leaf adjustable shaft flow fan is used very extensive, and bearing housing is as the key component of axial-flow blower, and can its working state be related to whole metallurgy, generating, desulphurization system and normally move.The normal flinger ring retaining oil that rotates with the axis that adopts of bearing housing oil sealing in the tradition, stop the leakage of lubricant oil in conjunction with the labyrinth seal form, but when bearing and main shaft size hour, the flinger ring role will be restricted, and when there is pressure reduction in sealing both sides air pressure, can cause a part of lubricant oil because of draught head along the main shaft surface seep.Because the above-mentioned leakage of oil problem of bearing housing frequent appearance in service has not only increased oil consumption and operating cost, has improved maintenance difficulties, also may cause bearing lubrication bad simultaneously, and produce potential safety hazard.

Summary of the invention:

It is a kind of for the seal arrangement that prevents the oil leak of axial-flow blower forced-lubrication bearing case that the purpose of this utility model is to provide.

Technical solution of the present utility model is:

The utility model relates to a kind of Seal in Bearing Box device, comprise end cap, sealing cover, reach the bolt fastener between end cap and sealing cover, it is characterized in that, also comprise rotary sleeve, lips reinforced seal and ventilation plug screw, one cover lips reinforced seal has been installed between sealing cover and rotary sleeve, the ventilation plug screw has been installed on the vent on end cap top.

End cap is provided with spill port.

Sealing cover is provided with oil back chamber, is provided with through hole below the oil back chamber.

Rotary sleeve is provided with the disc of projection, and the rotary sleeve middle part is provided with gets rid of oily broach.

The beneficial effects of the utility model are: the utility model is simple in structure, and is easy to process, solved bearing

The leakage of oil problem of case easy appearance in service has effectively improved the lubricant oil utilization efficiency, has promoted lubrication effect.

Description of drawings:

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is an embodiment's of the utility model configuration diagram.

Fig. 2 is the partial enlarged drawing of Fig. 1.

Embodiment:

The utility model relates to a kind of Seal in Bearing Box device that prevents leakage of oil, comprise end cap 1, sealing cover 2, and the bolt fastener 3 of 2 of end cap 1 and sealing covers, it is characterized in that, also comprise rotary sleeve 4, lips reinforced seal 5 and ventilation plug screw 6,4 of sealing cover 2 and rotary sleeves have been installed a cover lips reinforced seal 5, and 8 have installed ventilation plug screw 6 on the vent on end cap 1 top.

End cap 1 is provided with spill port 7, and sealing cover 2 is provided with oil back chamber 9, is provided with through hole 10 below the oil back chamber 9.Rotary sleeve 4 is provided with the disc 11 of projection, and rotary sleeve 4 middle parts are provided with gets rid of oily broach 12.

During seal arrangement work, spray to the pressure oil of roller bearing, roller bearing is lubricated, intercepted by end cap 1 behind the pressure oil process roller bearing rolling element, most of lubricant oil is stopped by end cap 1, flows to downwards in the little oil sump of roller bearing; The lubricant oil that sub-fraction is leaked is subjected to being rotated centrifugal force that the disc 11 of axle sleeve 4 upper process produces and is thrown in the cavity and enters spill port 7 along housing surface; Cross the oil of disc when being seeped into rotary sleeve 4 middle parts, the centrifugal force that gets rid of oily broach 12 that is designed in rotary sleeve 4 middle parts is brought in the oil back chamber 9 of sealing cover 2, and flows into spill port 7 through 3 through holes 10 of oil back chamber 9 bottoms; At sealing cover 2 and 4 of rotary sleeves a cover lips reinforced seal 5 is installed, to play the effect of isolated lubricant oil and external dust; At the vent 8 on end cap 1 top a ventilation plug screw 6 is installed in addition, with air pressure before and after the equalizer bearing case, prevent the oil leak that causes because of the bearing housing inside and outside differential pressure, through this 5 road leak free design, guaranteed the sealing that bearing support is good, solve the leakage of oil problem of bearing housing easy appearance in service, improve circulating lubrication efficient, and the safe operation of blower fan is reliably guaranteed.
