Description

A kind of bearing cavity exhaust stopple

Technical field

The utility model is related to the parts of bearings of pump, more specifically to a kind of bearing cavity exhaust stopple.

Background technology

As shown in Figure 1, pump is typically to be made of several parts such as rotor part, seal member, parts of bearings 1, rotating speed is higher Parts of bearings 1 generally all also use thin oil lubricant, in this way, on the one hand bearing cavity 2 is required to need good leakproofness, together When, bearing 3, which rotates at a high speed, makes bearing oil disturbance fever, bearing 3 generate heat, oil temperature rise, air expansion in bearing cavity 2, It needs to eject 2 internal high temperature gas of bearing cavity, therefore an exhaust stopple 4 is set on parts of bearings 1.

As shown in Fig. 2, the exhaust stopple 4, using common common part, including stopple 5 and lid 6, stopple 5 is resistance to Oily plastics are made, and two seals ring recess is opened on the lateral surface of stopple 5, the mounting O-shaped sealing ring 7, Ran Houzhi in seal groove It connects on parts of bearings 1, stomata 8 is opened among stopple 5, surrounding is evenly distributed with gas vent 9 to lid 6 below, makes by gas vent 9 Stomata 8 communicates (discharge directions are shown in the arrow direction in Fig. 2) with outside atmosphere.

But above-mentioned exhaust stopple there is it is following the defects of：

1. gas vent clearance gauge cun is smaller or after being used for multiple times, stopple coordinates more loose, stopple with the hole on parts of bearings Easily drop from parts of bearings, meanwhile, because of bearing, rotation drives lubricating oil splash at a high speed, and lubricating oil is also easily from stopple and axis It is leaked out between hole on bearing portion part in gap；

2. there is through hole on stopple, outside atmosphere is led directly to, the lubricating oil of splashing can also come out from stopple stomata, and along gas vent Outside is leaked into, generates some oil leakage phenomenons；

3. because stopple stomata leads directly to outside atmosphere, the foreign matters such as external dust, small winged insect can also enter in bearing bore body, from And pollute lubricating oil.

Utility model content

In view of the above defects of the prior art, the purpose of this utility model is to provide a kind of bearing cavity exhaust There is leakage, contaminated situation, make the safe to use, reliable of pump in stopple, the lubricating oil for avoiding bearing cavity.

To achieve the above object, the utility model adopts the following technical solution：

A kind of bearing cavity exhaust stopple, including stopple lid and stopple, offers through hole, stopple lid and stopple in stopple Upper end be connected, stopple upper end is equipped with several uniformly distributed gas vents, offers several gusset in stopple lid, the upper end of through hole is set There is filtering net plate, gusset is to compress filtering net plate, and through hole is interior to be equipped with several splashproof cut waters, and the lateral surface of stopple is equipped with screw thread, with Bearing bore body, which is formed, to be threadedly coupled, and gasket is also arranged on the lateral surface of stopple.

The stopple lid is to be threadedly coupled with the upper end of stopple.

The stopple upper end is set with stopple lid link position in hexagon, and gas vent is arranged on hexagon.

There are six the gas vent is set, semicircular in shape shape is respectively provided with.

There are two the splashproof cut water is set, the rear end of splashproof cut water is connected on the inner wall of through hole, before splashproof cut water End tilts down setting.

Several uniformly distributed tooth mouths are opened up on the week circle side of the stopple lid.

Several described gusset is set in radiation shapes.

In above-mentioned technical solution, a kind of bearing cavity provided by the utility model exhaust stopple is easy to make, Convenient for cleaning and draping, it can effectively prevent the leakage of lubricating oil and foreign enter bearing inside cavity, meanwhile, and adopt Be threadedly coupled also can effectively prevent exhaust stopple drop or lose.

Specific embodiment

The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.

Incorporated by reference to shown in Fig. 1 to Fig. 5, a kind of bearing cavity provided by the utility model is with stopple is vented, including stopple 11 two parts of lid 10 and stopple, make the utility model easy to make, and stopple lid 10 is used with the upper end of stopple 11 and is threadedly coupled, hole Through hole 12 is offered in plug 11,11 upper end of stopple is equipped with several uniformly distributed gas vents 13, several muscle is offered in stopple lid 10 Plate 14, several gusset 14 are set in radiation shapes, and the upper end of through hole 12 is mounted with filtering net plate 15, and gusset 14 is compressing filtering net plate 15, it sets in through hole 12 there are two splashproof cut water 16, is arranged to screw thread on the lateral surface of stopple 11, screw thread is formed with bearing cavity 1 Connection, prevents stopple 11 from dropping or losing, gasket 17 is also arranged on the lateral surface of stopple 11, to seal stopple 11 and axis The gap connected between cavity 1 is held, prevents the oil leak in bearing cavity 1.

Preferably, the stopple lid 10 is to be threadedly coupled with the upper end of stopple 11,11 upper end of stopple connects with stopple lid 10 It connects position to set in hexagon, gas vent 13 is arranged on hexagon, there are six gas vent 13 is set, is respectively provided with semicircular in shape shape, hole Several uniformly distributed tooth mouths 18 are opened up on the week circle side of corking 10.

Preferably, there are two the splashproof cut water 16 sets, the rear end of splashproof cut water 16 is connected on the inner wall of through hole 12, The front end of splashproof cut water 16 tilts down setting.

The utility model stopple lid 10 and stopple 11 are using being threadedly coupled, convenient for cleaning or replacing filtering net plate 15, during installation, Stopple lid 10 is opened, stopple 11 can be twisted to bearing cavity 1 with the spanner for being adapted to 11 upper end hexagon of stopple.

Installation two panels splashproof cut water 16 in through hole 12, and two panels splashproof cut water 16 partly overlaps, two panels splashproof cut water 16 Head downward, when coming in bearing cavity 1 on lubricating oil splash, can be blocked by splashproof cut water 16, and drip, can so prevent from flying Splash oil leakage phenomenon.

Filtering net plate 15 has been installed additional in 12 upper end of through hole, on the one hand, when oil gas rises to filtering net plate 15, oil gas can be liquefied as Oil, and drip, it prevents that oil gas comes out in bearing cavity 1, on the other hand, and prevents bearing cavity 1 and the direct phase of outside atmosphere It is logical, it can prevent external dust, small worm etc. from entering in bearing cavity 1, lubricating oil is prevented to be contaminated.

Using being threadedly coupled between stopple 11 and bearing cavity 1, it can prevent stopple 11 from dropping or losing, be avoided that stopple 11 The risk dropped out.Packing 17 is encrypted between stopple 11 and bearing cavity 1, so by the hole on stopple 11 and bearing cavity 1 it Between gap be fully sealed, can prevent oil leak in bearing cavity 1.

Stomata 13 is opened on 11 upper end hexagon of stopple, so reaches ventilation, the function of connection, and easy disassembly.

The radial gusset 14 of arrangement in stopple lid 10, can form radial direction exhaust passage, 10 intensity of reinforced hole corking, simultaneously Filtering net plate 15 can be tightly suppressed.The tooth mouth 18 arranged on the week circle side of stopple lid 10, it is also convenient while aesthetic effect is reached Twist stopple lid 10.10 upper face of stopple lid can arrange the marks such as corporate logo, stopple specification, rotation direction.

Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this practicality is new Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above Variation, the modification of embodiment will all fall in the Claims scope of the utility model.
