Air filtering and air drying are achieved through the dustproof sponges and the desiccant, oil mist is gathered through the expansion cavity and the meshy oil mist gathering device, so that oil linkage is prevented from occurring, a threaded connection structure is adopted, and therefore the gearbox ventilator is convenient to demount and easy to maintain.
Description
Technical field
The utility model belongs to the transmission device technical field, relates in particular to a kind of gear-box breather for wind power generating set.
Background technique
Gear-box as coupling transmission vitals is one of most important parts in the system, be efficient running and the rational life-span that guarantees gear, can add lubricant oil in the gear-box, in the course of the work, the oil temperature of lubricant oil can raise gradually, and then in transmission case, produce the oil gas of heat, because gear-box is the casing of sealing, along with the increase of oil gas, the pressure in the transmission case also can increase, so it is the oil gas of heat must be disposed in the outside atmosphere by exhaust gear, working properly to guarantee gear-box.Traditional exhaust gear is to adopt a breathing pipe, one end of breathing pipe stretches in the gear-box, the other end leads to atmosphere, but after work a period of time, the oil gas of lubricant oil can be assembled and forms profit and oil occurs getting rid of and in the phenomenon of exhaust port place generation oil impregnate in the gear-box, lubricant oil can be disposed in the atmosphere with oil gas along breathing pipe, has not only caused loss of lubrication but also befouling environment.Prior art is made certain improvement to this exhaust gear, has formed existing breather.
Existing breather mainly contains three kinds of structures, wherein a kind ofly is made up of breathing pipe and the oily device of retaining, and gear-box is inside and outside directly to be communicated with by breathing pipe, but in a humid environment, water vapour enters in the gear-box by pipeline, understands the quality that directly influence lubricant oil; Another kind of breather is as described in the breather of 200,620,140,812 1 kinds of speed reduceres of Chinese patent, formed by cap body, cap, spring, steel ball, the internal pressure jack-up spring that produces when relying on the gear-box operation and outside ventilation, this breather just can carry out pressure release when only producing malleation in inside, long-time running may cause gear-box inside to be in negative pressure state, does not reach ventilatory effect; Also have a kind of breather to be formed by ventilation body and breather line, place siccative in the ventilation body, breather line adopts straight tube structure, this structure has only been considered the functions/drying to the gear-box outer air, when in the gear-box running, producing a large amount of mist of oil, mist of oil still can overflow by breather line, produces leakage of oil.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of gear-box breather, to filtration and the drying of air, solves the problem of leakage of oil simultaneously when realizing breather work, and is convenient to dismantle and safeguard.
The purpose of this utility model will be achieved by the following technical programs:
A kind of gear-box breather comprises ventilation body and a breather line, and described ventilation body is cylinder-like structure, the top seal of described ventilation body; The bottom of described ventilation body is connected with described breather line, and the upper end-hole of described breather line is extended with an expansion cavity to the inside of described ventilation body, and the lower end mouth of described breather line is connected with gear-box; The internal communication of the upper end of described expansion cavity and described ventilation body, the lower end of described expansion cavity are provided with a netted carriage, and described netted carriage is provided with a netted oil mist trapping device; The bottom of the described ventilation body vent with internal communication described ventilation body that also be provided with at least one is coated with the dustproof sponge of each one deck up and down on the described vent, be filled with siccative between the described dustproof sponge.
Preferably, above-mentioned a kind of gear-box breather, wherein: the top of described ventilation body is by being connected sealing with a breather cover.
Preferably, above-mentioned a kind of gear-box breather, wherein: be provided with an O type circle between described breather cover and the described ventilation body.
Preferably, above-mentioned a kind of gear-box breather, wherein: between described ventilation body and the described breather cover by being threaded.
Preferably, above-mentioned a kind of gear-box breather, wherein: described netted oil mist trapping device is one by the intensive netted cylinder that is entwined of steel wire.
Preferably, above-mentioned a kind of gear-box breather, wherein: between the bottom of described ventilation body and the described breather line by welding or be threaded.
Preferably, above-mentioned a kind of gear-box breather, wherein: between the lower end mouth of described breather line and the gear-box by being threaded.
Outstanding effect of the present utility model is: a kind of gear-box breather of the present utility model utilizes dustproof sponge and siccative effectively to realize filtration and drying to air, collect mist of oil by expansion cavity and netted oil mist trapping device, avoided the generation of leakage of oil, adopt screw connection structure simultaneously, convenient disassembly is safeguarded simple.
Following constipation closes embodiment's accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the utility model embodiment's sectional view.
Embodiment
A kind of gear-box breather of present embodiment, as shown in Figure 1, comprise ventilation body 1 and breather line 2, ventilation body 1 is cylinder-like structure, the top of ventilation body 1 also is provided with an O type circle 4 that seals by the sealing that is threaded with breather cover 3 between breather cover 3 and the ventilation body 1; The bottom thread of ventilation body 1 connects or is welded with breather line 2, and the upper end-hole of breather line 2 is extended with expansion cavity 5 to the inside of ventilation body 1, and the lower end mouth of breather line 2 can be threaded with gear-box; The internal communication of the upper end of expansion cavity 5 and ventilation body 1, the lower end of expansion cavity 5 is provided with netted carriage 6, and netted carriage 6 is provided with one by the netted oil mist trapping device 7 of the intensive netted cylinder shape that is entwined of steel wire; The bottom of ventilation body 1 that also be provided with several with the vent 8 of internal communication ventilation body 1, be coated with the dustproof sponge 9 of each one deck up and down on the vent 8, be filled with siccative 10 between the dustproof sponge 9.
