Abstract
The utility model relates to road gates, and discloses an oil-leakage-proof structure of a road gate. The oil-leakage-proof structure comprises a driving motor and a reduction gearbox. The driving motor and the reduction gearbox are fixed onto a framework, reduction transmission mechanism with a gear transmission or worm transmission or gear-worm transmission function is arranged in the reduction gearbox, the driving motor is arranged on the upper side of the reduction gearbox in an inverted manner, an output shaft of the reduction gearbox is arranged above the reduction transmission mechanism, and the lower side of the reduction gearbox is sealed. The oil-leakage-proof structure has the advantage that oil leakage due to influence of the quality of an oil seal of a spindle of the motor, the quality of an oil seal of the output shaft of the reduction gearbox, abrasion to the oil seal of the spindle of the motor and abrasion to the oil seal of the output shaft of the reduction gearbox can be prevented.
Description
Technical field
The utility model relates to banister, especially relates to the banister leak-proof arrangement of not easy oil leakage of a kind of reduction box.
Background technology
Banister claims again car lug, for limiting the entrance and exit of the passage management equipment of motor-driven vehicle going on road, is now widely used in toll station, parking lot management management vehicle passage, for the discrepancy of management vehicle.At power-off or other in particular cases, when restrictor bar need to rely on human factor to rise and fall, traditional banister as shown in Figure 1, its motor 100 is all mounted in the below of reduction box 200, being connected below reduction box 200 of motor 100 and reduction box 200 like this, the operation of motor can affect its junction sealing, lubrication oil after operation certain hour in reduction box 200 there will be seepage, the oil sealing that simultaneously operation of motor also can be worn and torn on motor driving shaft, can produce the phenomenon of seepage lubrication oil equally.
Summary of the invention
For overcoming the shortcoming of the lubrication oil easy to leak of existing banister in reduction box, the utility model object is to provide the banister leak-proof arrangement of not easy oil leakage of a kind of reduction box.
The utility model is realized by following technical measures, a kind of banister leak-proof arrangement, comprise the drive motors and the reduction box that are fixed in frame, in described reduction box, be provided with gear drive, worm-drive or gear-worm geared reduction gearing mechanism, described drive motors is inverted in the top of reduction box, the output shaft of described reduction box is arranged on the top of reduction gearing mechanism, and the below sealing of described reduction box arranges.
As a kind of optimal way, described reduction gearing mechanism is double reduction transmission.
As a kind of optimal way, between the line shaft of described drive motors and reduction gearing mechanism, be endless screw-worm gear transmission, worm shaft oil sealing is arranged on reduction gearing mechanism top.
As a kind of optimal way, described shell of reduction box is I shape.
As a kind of optimal way, described shell of reduction box is Al-alloy casing.
Motor of the present utility model is positioned at reduction box top, thereby the oil sealing on electric machine main shaft is also arranged on the top of reduction gearing mechanism, the output shaft of reduction box is also arranged on the top of reduction gearing mechanism in addition, lubrication oil in reduction box is generally no more than the height of final drive shaft center line, so lubricated fuel head is much higher than in electric machine main shaft oil sealing and reduction gearbox output shaft oil sealing position.So the quality of electric machine main shaft oil sealing and reduction gearbox output shaft oil sealing and wearing and tearing can not affect leakage of oil.
Brief description of the drawings
Fig. 1 is the structural representation of traditional banister;
Fig. 2 is the decomposing schematic representation of the utility model embodiment;
Fig. 3 is the structural representation of the utility model embodiment;
Fig. 4 is the schematic appearance of the utility model embodiment;
Fig. 5 is the structural representation that the utility model embodiment uses on banister.
Detailed description of the invention
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A kind of banister leak-proof arrangement, referring to figs. 2 to Fig. 5, comprise the drive motors 1 and the reduction box 2 that are fixed in frame 20, in reduction box 2, be provided with gear drive, worm-drive or gear-worm geared reduction gearing mechanism, drive motors 1 is inverted in the top of reduction box 2, the output shaft 14 of reduction box 2 is arranged on the top of reduction gearing mechanism, and reduction box 2 below sealings arrange.Motor 1 is positioned at reduction box 2 tops, thereby the worm screw oil sealing 6 on the worm screw 3 that electric machine main shaft connects is also arranged on the top of reduction gearing mechanism, the output shaft 14 of reduction box 2 is also arranged on the top of reduction gearing mechanism in addition, lubrication oil in reduction box 2 is generally no more than the height of final drive shaft 11 center lines, so lubricated fuel head is much higher than in worm screw oil sealing 6 and reduction gearbox output shaft oil sealing 16 positions.Thereby the quality of worm screw oil sealing 6 and reduction gearbox output shaft oil sealing 16 and wearing and tearing can not affect leakage of oil.Because output shaft 14 center lines are main benchmark of design barrier gate machine core, final drive shaft 11 has obviously down dragged down corresponding height motor 1 relatively, has also improved the obstacle of motor 1 superelevation to frame 20.
Banister leak-proof arrangement of the present utility model, referring to figs. 2 to Fig. 3, on the basis of previous technique scheme, specifically reduction gearing mechanism is double reduction transmission, the worm gear 10 of worm screw 3 deceleration transmission final drive shaft 11 one end that connected by electric machine main shaft, the driven gear 13 on the driving gear 12 deceleration transmission output shafts 14 of final drive shaft 11 other ends; Worm screw 3 is fixing by bearing 4,5, and final drive shaft 11 is fixing by bearing 8,18, and output shaft 14 is fixing by bearing 9,15; The side cover 17 that reduction box 2 arranges output shaft 14 seals fixing by side cover oil sealing 7 by multiple screws 19.
Banister leak-proof arrangement of the present utility model, referring to figs. 2 to Fig. 5, the Al-alloy casing that concrete reduction box 2 shells are I shape on the basis of previous technique scheme.Reduction box 2 adopts I shape design with frame 20 standing parts, also saves aluminum alloy materials when ensureing reduction box 2 intensity.
More than that the utility model banister leak-proof arrangement is set forth; be used for helping to understand the utility model; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
