Description
Technical field
The utility model relates to a kind of speed reducer of oil-leakage-prevention.
Background technique
Speed reducer is widely used in metallurgy industry.But, in actual production speed reducer oil leakage phenomenon also ubiquity.Integrate, have following local leakage of oil: 1, inspection opening and the place's leakage of oil of upper box junction plane.Because oil temperature when speed reducer works raises, to make in casing air expand, pressure increases, thus case internal air pressure is greater than ambient pressure, and modal analysis according to observations, and effect is unsatisfactory at the scene for the usual speed reducer vent hood of all pressing for ventilating.Though speed reducer has Ventilated cap, air hole is too little, and easily by blockings such as steel mill's iron ash, greasy dirts, and each oiling all will open access plate oiling, easily produces leakage.In the speed reducer closed, every a pair gear is meshed to occur to rub and just wants the evolution of heat, and according to boyle boyle's law, along with the lengthening of running time, decelerating chassis internal pressure is increased thereupon, in case, lubricant oil is through splashing, and is sprinkled upon decelerating chassis inwall.Because the permeability of oil is stronger, under case internal pressure, which place is poorly sealed, and oil just oozes out wherefrom; 2, bearing (ball) cover output shaft place leakage of oil, common solution installs an oil baffle disc in the outside of bearing, but effect is not ideal.Speed reducer oil leakage phenomenon not only causes environmental pollution, and causes gearbox drive component wear serious because of insufficient lubrication, and component shorten working life greatly, and lubricant charging is frequent.While causing huge economic benefit loss, also bring great threat to actual safety in production.
At present, the most conventional control speed reducer leakage of oil method is: leak stopping.But, blindly " block up " passively and make control speed reducer leakage of oil blindness and passive more.Practice for many years shows that effect is very undesirable.
Model utility content
Technical problem to be solved in the utility model is that the deficiency existed for above-mentioned prior art provides a kind of anti-oil-leakage retarding machine preventing speed reducer leakage of oil.
The technological scheme that the utility model adopts is: a kind of speed reducer of oil-leakage-prevention, it perspective air-breather comprising casing and arrange mutually with casing, it is characterized in that lower cover plate, rectangular shape air hole that described perspective air-breather is comprised upper cover plate, is connected with upper cover plate by connecting plate, the lower end of described air hole is interted successively after upper cover plate and lower cover plate and is stretched in casing.
By technique scheme, in the outlet of air hole, be provided with mazy type dust baffle plate.
By technique scheme, be provided with the gear oil flange plate of perpendicular setting at the lower limb of lower cover plate.
By technique scheme, the logical lid that described speed reducer comprises output shaft, arranges bearing with output shaft mutually, arrange mutually with output shaft, the supporting surface of described logical lid is arranged at intervals with multiple oil duct vertically, and support end face is provided with axial spill port, and described spill port is communicated with each oil duct.
By technique scheme, bearing and logical cover between be provided with oil baffle disc, described oil baffle disc is arranged on the logical interior step place covered.
By technique scheme, in described logical lid step end face on be circumferentially arranged at intervals with multiple oil return aperture.
Beneficial effect acquired by the utility model is: the utility model is by arranging the double-layer perspective device and the logical lid of return flow type with drainage function, effectively backflow is dredged to the lubricant oil in speed reducer, effectively prevent the leakage of oil situation of speed reducer, improve the working life of speed reducer greatly; Air hole is arranged to right angle type and can be prevented oil droplet from directly spilling, internal vent place is arranged to mazy type dust baffle plate, enter in speed reducer with blocks dust, when dirt accumulation is herein more, can take off and blow off with airduct, the problem of air pressure inequality can be solved, effectively prevent the problem of seepage because speed reducer internal pressure is excessive.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figs. 1-7, the speed reducer of a kind of oil-leakage-prevention that the present embodiment provides, the perspective air-breather that it comprises casing 7, arrange mutually with casing, output shaft, the logical lid 8 arranging bearing 10 with output shaft mutually, arrange mutually with output shaft, lower cover plate 4, rectangular shape air hole 1 that described perspective air-breather is comprised upper cover plate 2, is connected with upper cover plate 2 by connecting plate 3, the lower end of described air hole 1 is interted successively after upper cover plate and lower cover plate and is stretched in casing 7.Wherein upper cover plate 2 is for blocks dust and the effect playing support, lower cover plate 4 is positioned on the edge of a wing of block inside, for stopping the oil droplet upwards splashed, also can play certain supporting effect, (being installed on side lower after on speed reducer) on the edge of a wing of block inside has three spill ports; The gear oil flange plate 5 of perpendicular setting is provided with, for stopping the oil droplet of oblique splashing at the lower limb of lower cover plate 4; Like this, the lubricant oil that the overwhelming majority is splashed all directly is stopped back in speed reducer, and the lubricant oil that part is oozed out from lower cover plate 4 and the edge of a wing, the plane of inclination along speed reducer is flowed downward and accumulates in lowest part, then flow back to speed reducer inside by spill port.Because the space between upper and lower cover plates does not have dust, therefore the lubricant oil of backflow can not bring impurity into.
In the utility model, in the outlet of air hole 1, be provided with mazy type dust baffle plate.This air hole is made right angle type and can be prevented oil droplet from directly spilling, internal vent place is arranged to mazy type dust baffle plate, enter in speed reducer with blocks dust, when dirt accumulation is herein more, can take off and blow off with airduct, the problem of air pressure inequality can be solved, effectively prevent the problem of seepage because speed reducer internal pressure is excessive.
In order to prevent the generation of leakage of oil situation further, the supporting surface of described logical lid 8 is arranged at intervals with multiple oil duct 13 vertically, support end face is provided with axial oil return aperture 12, and described spill port 12 is communicated with each oil duct 13.Between bearing 10 and logical lid 8, be provided with oil baffle disc 9, described oil baffle disc 9 is arranged on the interior step place of logical lid 8, further reduces the impact force of lubricant oil to Sealing, makes the lubricant oil overflowed from bearing directly can not enter Tong Gai.In addition, in described logical lid 8 step end face on be circumferentially arranged at intervals with 8 oil return apertures 11, even if there is the lubricant oil crossing oil baffle disc to flow into the inside of logical lid, this part oil also flows back in speed reducer by the backflow aperture of platform in logical lid, effectively prevents the generation of speed reducer leakage of oil situation.
