Abstract
The utility model relates to an upright reducer leakproof seal device, while the prior art can not resolve the leakage seal problem of upright reducer and upright rotation machine. The upright reducer leakproof seal device is characterized in that an oil chamber is provided under the reducer box body; the lower end of an output shaft is mounted with an oil thrower wheel for throwing flown oil into the oil chamber; the gear shaft around the output shaft can absorb oil; the center of the gear shaft is drilled with an oil suction hole from down to up, the upper end is provided with a plurality of transverse holes, and an oil sucker at lower end is inserted into the oil chamber; when the gear shaft rotates, the transverse holes at upper end can discharge the air in the oil suction holes and the transverse holes to form vacuum condition, to suck the oil of the oil chamber upwards and discharge the oil from the oil throwing transverse holes, thereby cyclically lubricating components from up to down by lubricant and realizing leakproof sealing effect.
Description
The model utility field
The utility model relates to a kind of vertical type speed reducer (change gear) leak-proof sealing device, belongs to general gearing field.(hereinafter to be referred as seal arrangement)
Background technique
All the time, the seepage sealing problem of vertical type speed reducer (change gear) and vertical rotary machine can not get solving always.The method that the liquid oils that general employing is installed a plurality of seal rings additional or adopted oil pump to leak down at the output axle head is extracted out solves the problems referred to above.Because, the wearing and tearing of oil sealing and the damage of oil pump, thus the frequent generation of leakage of oil incident caused, cause certain loss to the user.Therefore, fundamentally do not address the above problem completely.
The model utility content
The purpose of this utility model provides a kind of vertical type speed reducer (change gear) leak-proof sealing device satisfying manufacturing requirements, and this device adopts centrifugal vacuum oil suction principle, the liquid oils of seepage is sucted the top discharge.Spontaneous current lubricates each parts down again.Its technical characterstic is that a grease chamber is arranged below the speed reducer casing.The output shaft lower end is equipped with disc, the oil that flows down can be thrown in the grease chamber, utilizes the axial gear shaft oil suction of output.This Gear center has bored an oil-sucking hole from bottom to up, there is an amount of cross-drilled hole the upper end, the oil-Absorbing nozzle straight cutting of lower end is gone in the above-mentioned grease chamber, when gear shaft rotates, the cross-drilled hole of upper end discharges the air in oil-sucking hole and the cross-drilled hole, form vacuum, discharge so that the oil of grease chamber upwards inhaled from getting rid of oily cross-drilled hole, thus realized lubricant oil from top to down the circulating lubrication parts purpose and reached the effect of leakproof seal.
The utlity model has simple in structurely, oil absorbency is reliable, characteristics such as high lubricating effect.
Description of drawings
Accompanying drawing is the structure sectional view of seal arrangement
Among the figure: casing (1), grease chamber (2), output shaft (3), seal ring (4), disc (5), oil-Absorbing nozzle (6), gear shaft (7), get rid of oily cross-drilled hole (8), motor (9).
Embodiment
Now be illustrated in conjunction with the accompanying drawings
From accompanying drawing, seal arrangement is made up of speed reducer casing, seal ring, disc, oil-Absorbing nozzle and gear shaft spare.Its characteristics are, the center of gear shaft (7) is processed with a straight hole, the top is processed with an amount of oily cross-drilled hole (8) that gets rid of, one oil-Absorbing nozzle (6) is arranged at the bottom, and communicates with above-mentioned straight hole, and this oil-Absorbing nozzle (6) directly is inserted in the grease chamber (2) of casing (1), when gear shaft rotates, liquid oils in grease chamber (2) can be drawn to the top, in the bottom of output shaft (3) disc (5) is installed, so that the oil that will flow down get rid of in grease chamber (2).
Concrete oil suction principle is: when motor (9) driven gear axle (7) rotates, the oily cross-drilled hole (8) that gets rid of at this top produces centrifugal force, air in the oil suction straight hole at gear shaft (7) center is discharged, produce suction to form vacuum in the pore, therefore, by oil-Absorbing nozzle the oil in grease chamber (2) is drawn to the top and gets rid of oily cross-drilled hole (8) and discharge.When the oil of discharging flows down downwards, through the centrifugal force of disc (5) endlessly oil get rid of in grease chamber (2), to form a lubricated cyclic process.Prevented the leakage of oil problem that output shaft (3) output axle head causes because of the damage and the inefficacy of seal ring like this.Seal ring (4) has played the dual fail-safe effect.
The utlity model has good sealing effect, anti-leakage is strong, need not increase by a cover oil pump systems oil suction, and the manufacturing process letter Single, save cost, stable and reliable for performance. The characteristics such as long service life. Be applicable to vertical installation and forbid the subtracting of downward leakage of oil The speed machine is with other gearings.
Claims (1)
- A kind of vertical type speed reducer (change gear) leak-proof sealing device is made up of speed reducer casing, seal ring, disc, oil-Absorbing nozzle and gear shaft, it is characterized in that: the center of gear shaft (7) is processed with a straight hole, the top is processed with an amount of oily cross-drilled hole (8) that gets rid of, there is an oil-Absorbing nozzle (6) bottom and communicates with above-mentioned straight hole, this oil-Absorbing nozzle (6) directly is inserted in the grease chamber (2) of casing (1), when gear shaft (7) rotates, the liquid oils in grease chamber (2) can be drawn to the top; In the bottom of output shaft (3) disc (5) is installed, so that the oil that will flow down gets rid of in grease chamber (2).
