Description
Technical field
The present invention relates to the multi-functional oiling respirators that a kind of motor bearings uses.
Background technique:
There are the fuel tank or oil groove of a storage lubricating oil using the motor bearings of thin oil lubricant, in motor work, because
Bearing and motor shaft friction and generate heat and heat lubricating oil so that volume of air increases even in lubricating oil and cavity
Generating mist of oil makes pressure rise in bearing bore body be greater than ambient atmosphere pressure；When bearing cavity inner temperature is lower from height, lubrication
Oil from large to small, causes bearing cavity internal pressure to be less than ambient atmosphere pressure with volume of air in cavity.It such as cannot timely adjustment axis
Cavity internal pressure is held, just will appear oil leak or sucks external sundries in bearing bore body and the problem of cause bearing damage.Also
Excessive gas in cavity cannot such as be discharged when bearing oiling in time, then will appear lubricating oil splash, both having wasted lubricating oil also reduces
Oiling efficiency.
Summary of the invention:
The object of the present invention is to provide the multi-functional oiling respirators that a kind of motor bearings uses, and are mounted on motor bearings chamber
The top of body for bearing oiling and adjusts bearing cavity internal pressure and external atmosphere pressure holding balance, avoids oil leak or suction
Enter sundries.The technical solution of the present invention is as follows: the multi-functional oiling respirator that a kind of motor bearings uses, respirator lid 2 passes through interior
Screw thread is connected as one with respirator ontology 1, forms multi-functional oiling respirator, and vented platen 2-3 will be empty with ventilation inner cover 2-2
Gas filter screen 2-4 is clipped in the middle by the way of welding and is fixed together, the venthole on vented platen 2-3 and ventilation inner cover 2-
Venthole on 2 corresponds, and respirator connector 1-1, respiratory siphon 1-4 and pipe plug 1-5 will by the way of clamping and welding
Oiling filter screen 1-3 is fixed on respiratory siphon 1-4 inner wall, installs snorkel 1-2, snorkel with a hole on pipe plug 1-5
The lower end 1-2 welds together with pipe plug 1-5, and spot welding is fixed between the upper end snorkel 1-2 and respirator connector 1-1.
The ventilation center inner cover 2-2 is machined with several circular holes, is machined on vented platen 2-3 and ventilation inner cover 2-2
The circular hole of the identical quantity in center hole, size and location, airstrainer 2-4 are sandwiched in ventilation inner cover 2-2 and vented platen
Between 2-3, vented platen 2-3 is aligned with the hole on ventilation inner cover 2-2, the edge of vented platen 2-3 and ventilation inner cover 2-2 welding
Air filter module is formed together.
Working principle of the present invention:
In motor operation, the multi-functional oiling respirator of bearing cavity through the invention keeps the pressure in bearing cavity
It is identical as ambient atmosphere pressure.Air enters respiratory siphon 1-4 by hole on respiratory siphon 1-4 and oiling filter screen 1-3 in cavity
Inner cavity, then ventilate inner cover 2-2 centre bore, airstrainer 2-4 and vented platen 2-3 enter outer cover 2-1 and ventilation inner cover
In the cavity of 2-2 composition, is communicated finally by the hole at ventilation inner sleeve 2-2 outer circle with ambient air, keep external and internal pressure consistent.
The filtering that airstrainer 2-4 and oiling filter screen 1-3 will be passed through into the intracorporal air of bearing bore, avoids miscellaneous in air
Object enters bearing cavity.When oiling, the sundries in lubricating oil can be stopped external in bearing bore by oiling filter screen 1-3.Work as axis
Cavity inner temperature raising is held, air pressure is higher than ambient pressure in cavity, and the intracorporal air of chamber is exhaled by the multi-functional oiling of the utility model
Haustorium is discharged in environment；When air pressure is lower than ambient pressure in cavity, then environmental air passes through the multi-functional oiling of the utility model
Respirator enters in bearing cavity.
When needing oiling in motor bearings, respirator lid 1 is backed out, lubricating oil is infused after being filtered by respirator ontology 1
Enter in bearing.The specific method is as follows: lubricating oil slowly being poured into respirator connector 1-1, pays attention to not forgiving and pour into snorkel
In 1-2, lubricating oil is entered in respiratory siphon 1-4, after oiling filter screen 1-3 filtering, is injected by the hole on respiratory siphon 1-4
In bearing cavity, snorkel 1-2 can be consistent with holding chamber inside and outside air pressure when oiling, avoids lubricating oil splash, improves oiling effect
Rate.
Inventive technique effect:
The present invention meets the motor bearings self-aligning bearing cavity internal pressure and external environment atmosphere using thin oil lubricant
Pressure keeps balance, avoids oil leak or sucking sundries, moreover it is possible to improve lubricating oil injection efficiency, avoid splash.Vented platen 2-3 and logical
Airstrainer 2-4 is clipped in the middle by the way of welding and is fixed together by gas inner cover 2-2, the ventilation on vented platen 2-3
Venthole on hole and ventilation inner cover 2-2 corresponds.Respirator connector 1-1, respiratory siphon 1-4 and pipe plug 1-5 are using clamping
Oiling filter screen 1-3 is fixed on respiratory siphon 1-4 inner wall with the mode of welding.It is logical that a hole installation is processed on pipe plug 1-5
Tracheae 1-2, the lower end snorkel 1-2 weld together with pipe plug 1-5, point between the upper end snorkel 1-2 and respirator connector 1-1
Solid welding is fixed.The filtering that airstrainer 2-4 and oiling filter screen 1-3 will be passed through into the intracorporal air of bearing bore, avoids sky
Sundries in gas enters bearing cavity.When oiling, the sundries in lubricating oil can be stopped by oiling filter screen 1-3 in bearing cavity
Outside.To avoid corrosion from polluting, stainless steel material is can be used in present apparatus all material.
