Abstract
The utility model relates to the technical field of speed reducers, in particular to a breather plug of a speed reducer. The breather plug comprises a hollow outer plug body, the lower portion of the hollow outer plug body is in threaded connection with the speed reducer, a plug cap is sleeved on the upper portion of the outer plug body, a clearance for airflow is formed between the outer plug body and the plug cap, an inner plug body is mounted in the outer plug body and provided with oil baffle plates, and a clearance for airflow is formed between the oil baffle plates. The breather plug of a speed reducer is novel in structure, can guarantee excellent ventilation property of the speed reducer, simultaneously prevents lubricating oil splashing out of the breather plug, and avoids blocking passages.
Description
Technical field
The utility model relates to the speed reducer technical field, especially a kind of breather plug of speed reducer.
Background technique
Speed reducer inside temperature when work raises and makes air expansion, in order not damage the dynamic oil sealing of speed reducer, air-breather need be set come the inside and outside atmospheric pressure of balance speed reducer, the breather plug of existing speed reducer is to make a call to a coaxial hole on the screw rod, make a call to a horizontal hole on the nut, two holes link to each other, reach the ventilation purpose, this abat-vent lubricant oil in use can spatter in the hole, along with the rising of temperature, under the effect of gas even can overflow and stain casing, lubricant oil residual in the hole can stick dust etc., and the time has been grown and can cause obstruction, influences the ventilation of breather plug, thereby the speed reducer internal pressure is raise, influence proper functioning.
The model utility content
The technical problems to be solved in the utility model is: a kind of breather plug of speed reducer is provided, and the breather plug that solves speed reducer can spill lubricant oil, easily the technical problem of blocking.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of breather plug of speed reducer, the outer cock body that comprises hollow, outer cock body bottom is threaded with speed reducer, outer cock body top is set with cock cap, the gap that has supplied gas to flow between outer cock body and the cock cap, in the outer cock body inner plug body is installed, inner plug body has grease baffle, the gap that has supplied gas to flow between the grease baffle.
Further, the grease baffle of inner plug body is the fan-shaped grease baffle of two helical layer formula structures, and the grease baffle on upper strata has a down dip from right to left, and the grease baffle of lower floor has a down dip from left to right.
Further, outer cock body middle part is provided with shoulder block, and the smooth and easy mobile gap of supplied gas is arranged between shoulder block and the cock cap, and outer cock body outer wall is provided with card article, and the cock cap inwall is provided with corresponding draw-in groove, and outer cock body is connected by the card article draw-in groove with cock cap.
Further, card article is the cock body end face outside axially exceeding, and the draw-in groove top is provided with spacing muscle.
Further, the cock cap outer wall is provided with anti-skidding line.
The beneficial effects of the utility model are that the breather plug novel structure of speed reducer of the present utility model can also prevent that lubricant oil from spilling breather plug when guaranteeing the good venting capability of speed reducer, the problem of passage can not occur.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. outer cock body 11. card articles 2. inner plug bodies 21. grease baffles 3. cock caps 31. draw-in grooves among the figure.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the breather plug of a kind of speed reducer of the present utility model, the outer cock body 1 that comprises hollow, outer cock body 1 bottom is threaded with speed reducer, outer cock body 1 top is set with cock cap 3, and the gap that has supplied gas to flow between outer cock body 1 and the cock cap 3 is equipped with inner plug body 2 in the outer cock body 1, inner plug body 2 has grease baffle 21, the gap that has supplied gas to flow between the grease baffle 21.
Further, the grease baffle 21 of inner plug body 2 is the fan-shaped grease baffle of two helical layer formula structures, and the grease baffle 21 on upper strata has a down dip from right to left, and the grease baffle 21 of lower floor has a down dip from left to right.
Further, outer cock body 1 middle part is provided with shoulder block, the gap that has supplied gas to flow between shoulder block and the cock cap 3, and outer cock body 1 outer wall is provided with card article 11, and cock cap 3 inwalls are provided with corresponding draw-in groove 31, and outer cock body 1 is connected by card article 11 draw-in grooves 31 with cock cap 3.
For between the shoulder block that guarantees outer cock body 1 and end face and the cock cap 3 enough gaps being arranged, further, card article 11 is cock body 1 end face outside axially exceeding, and draw-in groove 31 tops are provided with spacing muscle.
For making things convenient for the installation of breather plug, further, cock cap 3 outer walls are provided with anti-skidding line.
During use, gas enters from the outer cock body 1 of hollow, pass inner plug body 2, discharge from the gap between outer cock body 1 and the cock cap 3, the lubricant oil that spatters at breather plug is blocked by the grease baffle 21 of inner plug body 2, and can flow back in the casing along the true dip direction of grease baffle 21, because being two helical layer formula sector structures, grease baffle 21 can block lubricant oil fully, prevent to spill to casing.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.
