Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of vacuum extractor, particularly to a kind of reductor vacuum extractor.
Background technology
Reductor is a kind of individual components being made up of the gear drive being enclosed in stiff case, worm-drive, pinion-endless screw transmission, the speed reduction gearing being commonly used between driving link and work package, between prime mover and working machine or actuator, play coupling rotating speed and the effect of transmission torque, apply extremely wide in modern mechanical.Single-stage and multistage speed reducer can be divided into according to transmission progression difference；Cylindrical gear reducer, conical gear reducer and circular cone-roller gear running wheel reductor can be divided into according to gear shape；Expansion, shunting can be divided into again according to the arrangement form of transmission and enter together shaft type reductor.
Above-mentioned various reductor is in use, in order to avoid gear teeth odontotripsis, the tank filler sleeve that will pass through to offer on box body of speed reducer is to box house oil addition, to increase the lubricant effect between inner body, increase the service life, but after reductor runs a period of time, internal easily heating, lubricating oil is expanded, chemical reaction occurs, cause internal producing pressure and leakage of oil.
Having some vaccum-pumping equipments of sale in the market, some has also applied for that patent, such as Chinese patent literature data disclose a kind of vacuum extractor [application number: 200920158159.0；Authorization Notice No.: CN201428598Y], including actuator, vacuum pump, support shell, air exhaust nozzle, shaft coupling and planetary gear reducing mechanism, actuator and support shell link into an integrated entity, vacuum pump is arranged on support enclosure, air exhaust nozzle spiral-lock is on the lower surface supporting shell, actuator is provided with an output shaft along its longitudinal central axis line, cross recess it is provided with vertically on the lower surface of this output shaft, the upper end of shaft coupling is assemblied in cross recess, the lower end of shaft coupling is connected with the power shaft of planetary gear reducing mechanism, the output shaft of planetary gear reducing mechanism is connected with the power shaft of vacuum pump.The volume of this vacuum extractor is little, but structure is complicated, manufacturing cost is high, air exhaust nozzle need to be inserted during evacuation in the tank filler sleeve of reductor and bleed, after evacuation, air exhaust nozzle is detached tank filler sleeve, even if quickly plug cock being threadeded with tank filler sleeve, still suffering from air and entering in decelerating chassis body from tank filler sleeve, in decelerating chassis body, vacuum is bad, and reductor in use still suffers from the excessive phenomenon causing leakage of oil of internal pressure.
Chinese patent literature data also discloses a kind of air exhauster [application number: 200920061523.1；Authorization Notice No.: CN201448216U], including shell, one end of shell is equipped with air exhaust nozzle, shell is built with pump bowl, the air inlet of pump bowl is identical with air exhaust nozzle, and shell, built with motor, the motor shaft of motor connects and has rotating disk, the tail end deviation electrical axis of the piston rod of pump bowl is hinged on rotating disk, and shell is built with the electric supply installation electrically connected with motor.This air exhauster is small and exquisite, and it is the most convenient to use, but the problem being difficult on reductor after there is also evacuation carry out sealing.
Summary of the invention
It is an object of the invention to for the above-mentioned problems in the prior art, it is provided that a kind of simple in construction, easy to operate and make the reductor vacuum extractor that vacuum is good.
The purpose of the present invention can be realized by following technical proposal: a kind of reductor vacuum extractor, described reductor includes casing, described casing is provided with the oil nozzle protruding from casing and being connected with box house, described oil nozzle is threaded plug cock, it is characterized in that, this vacuum extractor includes tubular vacuum tube, described vacuum tube is axially equipped with the bull stick that can move axially along vacuum tube, the lower end of described bull stick has the location division of delivery plug location, vacuum tube is stretched out in the upper end of bull stick, the lower end of described vacuum tube has the connection end for connecting oil nozzle, it is provided with sealing structure between upper end and the bull stick of vacuum tube, the sidepiece connection between inwall and the bull stick outer wall of described vacuum tube with air flue and vacuum tube has the trachea being connected with air flue, the other end of described trachea connects vacuum pump.
nullWhen this reductor uses with vacuum extractor，The connection end of vacuum tube lower end is connected with oil nozzle，Plug cock is positioned by the location division of bull stick lower end，Rotate bull stick afterwards，Bull stick drives plug cock to depart from oil nozzle，Then bull stick is made to move to vacuum tube top axial，Oil nozzle is connected with air flue，Vacuum pump works，Air in casing enters trachea through air flue from oil nozzle，So air in vacuum pump extraction casing，After completing evacuation，Bull stick is made to move axially to vacuum tube lower end，Rotating bull stick afterwards makes the location division of bull stick lower end drive plug cock to threaded with oil nozzle，Air flue does not connects with oil nozzle，Then vacuum tube is taken off，Complete the evacuation of casing，Easy to operate，The sealing that bull stick rotates and sealing mechanism ensure that between bull stick and vacuum tube during moving axially，After evacuation, plug cock and oil nozzle are easy to connect，Air will not be made to enter in casing，In casing, vacuum is good，Casing is in negative pressure state all the time，Greatly reduce reductor original because running a period of time，Box house heating makes lubricating oil expand、Produce chemical reaction，Box house is caused to produce pressure and leak oil condition，Reductor can the most normally be worked，Service life is long.
In above-mentioned reductor vacuum extractor, described sealing structure includes that vacuum tube upper end has the flange of fold inward, and the interior edge of described flange is tightly contacted bull stick, and described flange is fixed with the sealing ring between flange and bull stick.Sealing ring ensure that the sealing between flange and bull stick, also avoids dust to enter between flange and bull stick, it is to avoid abrasion, extends service life.
As another kind of situation, in above-mentioned reductor vacuum extractor, described sealing structure includes that vacuum tube upper end has the flange of fold inward, and described flange is threadeded with bull stick.
In above-mentioned reductor vacuum extractor, described trachea connects pressure regulator valve.Can accurate air pressure in control chamber body by pressure regulator valve, it is ensured that there is in casing enough vacuum.
In above-mentioned reductor vacuum extractor, the described end that connects is that rubber is made and tubular rubber base.Rubber base has elasticity, it is possible to be well buckled on oil nozzle, good airproof performance.
In above-mentioned reductor vacuum extractor, described location division is the projection protruding from bull stick lower end.Projection can embed plug cock, so that bull stick can drive plug cock lifting, rotate.
In above-mentioned reductor vacuum extractor, described bull stick upper end has the scrap (bridge) of outwards turnover, and the top of described bull stick offers the rotating hole of hexagonal configuration.Scrap (bridge) avoids bull stick to come off from vacuum tube, and can gripping scrap (bridge), that bull stick is moved axially is convenient and swift, inserts rotating hole by hexagonal bull stick and can conveniently drive bar rotation, so that plug cock threadeds fastening with oil nozzle.
Compared with prior art, simple and compact for structure with vacuum extractor of this reductor, it is possible to convenient air in decelerating chassis body is extracted, and vacuum is good in ensureing decelerating chassis body, thus reduce the increase of box body of speed reducer internal pressure and leak oil condition.
