Abstract
Gear-box piston type air-breather, belongs to gear drive field.The utility model overcome gear-box due to changed by inside and outside differential pressure influenced and cause gear-box occur oil leakage phenomenon.Its composition of the utility model includes: gear case body, plane is equipped with stairstepping through-hole one on the gear case body, piston is provided in the stairstepping through-hole one, the upper plane of the piston is connect with pressure spring one end, upper plane connection in the other end and vent hood of the pressure spring, the lower end of the vent hood is detachably connected with sealing plate, central through hole one is equipped in the middle part of the sealing plate, one ring set of central through hole of sealing plate is on piston, plane is detachably connected on the lower end of the sealing plate and gear case body, gasket is provided between gear case body and sealing plate.The utility model is by the inside and outside portion's pressure difference of piston adjusting tooth roller box, to solve gearbox leakage.
Description
Technical field
The utility model relates to a kind of gear-box air-breathers, belong to gear drive field.
Background technique
When larger change occurs for gear-box working environment, gear rotational speed, the air pressure of gear-box inside and outside can occur sharply to become
Change, when the inside and outside portion's air pressure difference of gear-box reaches certain numerical value, the lubrication oil gas inside gear-box is just easily flowed out.It is existing
Gear-box air-breather structure it is simple, can not solve due to inside and outside differential pressure change caused by Leakage, so as to cause profit
Lubricating oil is reduced, and increases the abrasion in gear drive, the service life for eventually leading to gear-box substantially reduces.
In addition, gear wear is inevitable during gear transmission, iron powder can be generated in abrasion,
Iron powder is usually mixed into lubricating grease.When iron powder increases, as the flowing of lubricating grease can also cause certain abrasion to gear,
Original gear-box air-breather can not solve the problems, such as this.
Summary of the invention
The purpose of the utility model is to provide a kind of gear-box piston type air-breathers, to overcome gear-box due to by inside and outside
Pressure difference variation influence and cause gear-box occur oil leakage phenomenon.
Above-mentioned purpose is realized through the following technical scheme:
Gear-box piston type air-breather, composition includes: gear case body, and plane is equipped on the gear case body
Stairstepping through-hole one is provided with piston in the stairstepping through-hole one, and the upper plane of the piston is connect with pressure spring one end,
Upper plane connection in the other end and vent hood of the pressure spring, the lower end of the vent hood detachably connects with sealing plate
It connects, central through hole one is equipped in the middle part of the sealing plate, one ring set of central through hole of sealing plate is on piston, the sealing
Plane is detachably connected on the lower end of plate and gear case body, and gasket is provided between gear case body and sealing plate.
The beneficial effect of the utility model compared with the existing technology is:
The utility model is a kind of gear-box piston type air-breather, is pressed by the inside and outside portion of the adjustable gear-box of piston
Difference, to solve gearbox leakage.When gear-box causes in gear-box since gear rotational speed is high or working environment influences
When portion's temperature increases, air pressure inside is also increased.At this point, piston can be moved up due to gas pressure, thus there is gap,
So that gear-box internal gas discharges outward, in the case where oil-proof, gear-box air pressure inside is reduced.In the normal work of gear-box
Make under situation, the pressure spring of piston upper end can push down piston, to realize the sealing inside gear-box.Rank is provided among piston
Trapezoidal hole two, is also provided with demountable magnetic pole in stairstepping through-hole two, and under normality, magnetic pole lower end is together with piston one
It is same to go deep into lubricating grease, the iron powder generated in lubricating grease due to gear wear can be sucked.Periodic cleaning magnetic pole, to subtract
Iron powder in few lubricating grease, and then extend the service life of gear-box.

Sealing plate 3 in the middle part of be equipped with central through hole one, one ring set of central through hole of sealing plate 3 is on piston 7, the sealing plate 3
Lower end (passing through screw) be detachably connected with plane on gear case body 1, be provided between gear case body 1 and sealing plate 3
Gasket 2.
Specific embodiment 2: as shown in Figure 1, present embodiment is made furtherly to specific embodiment one
It is bright, it is equipped with stairstepping through-hole two in the middle part of the piston 7, is provided with magnetic pole 8, the ventilation in the stairstepping through-hole two
It covers 4 upper ends and is equipped with central through hole two, be fixed with filter screen 9 in the central through hole two, filter screen 9 is utilized to filter outside air
Middle dust prevents extraneous dust from entering in lubricating grease, pollutes lubricating grease；4 inner wall of vent hood is fixed with dry ring 6, for absorbing
Moisture in outside air, it is ensured that the working environment of lubricating grease in gear-box.
